Sugar Beet Pests and Diseases Biocontrol Management

The pest and disease issue in sugar crops is a major issue that has raised concern since a number of insect pests and pathological organisms have posed threat to the productivity of crops and the quality of sugar such as long term sustainability of farming systems. The extensive knowledge of the prevalent sugar beet pests and diseases enables the growers to employ the appropriate management strategies on time and at appropriate levels that safeguard the crops without violating organic certification and in addition to abiding by the environmental custodianship.

There are several groups of insects that lie on sugar crop pests. The piercing-sucking insects like aphids, leafhoppers and whitefly weaken the plants by sucking the sap and also play a role in transmitting viruses, like the curly top virus and other systemic pathogens. Direct defoliation and skeletonization- The insect weaver beet armyworms, cutworms, and weevils cause negative effects on stems and roots, and mostly leaves can be affected, leading to loss of plant vigor and adversely affecting sugar levels. The larvae that reside in the soil like the sugar beet root maggots and wireworms, as well as the seed maggots, destroy the root systems and contribute to yield loss even more.

Crop disease is also vulnerable to sugar crops. Fungal or fungi are found in roots and crowns and cause fungus diseases that include Rhizoctonia root rot, Phytophthora root rot, Fusarium yellows, and Sclerotinia crown rot that lead to stunted growth, wilting and rotting. Foliar-induced leaf spots include cercospora, powdery mildew, rust, Ramularia, downy mildew, which in turn reduces the effectiveness of photosynthesis which results in early sugar beet leaf diseases loss. Sugar beet bacterial diseases such as bacterial blight are known to cause leaf spotting, lesions at the stems, and damage in the vascular tissues and nematodes such as root-knot nematodes are known to cause galls that disrupt nutrient and water absorption.

The traditional sugar pest and disease control which involves the use of synthetic chemical pesticides alone is increasingly being challenged. Recurring exposures to sugar beet pesticides​ may result in resistant populations of pests, altered populations of helpful human insects promotes natural pest sugar beet pest control and pollination, deposits under crops and causes soil and water pollution. These concerns have pointed towards the importance of pest and disease management measures that are sustainable and based on the use of biological solutions, which protect the health, productivity and ecology of crops.

Organic Sugar Beet Pest Control

Target Pests: Aphid, Spider mite,Sugar beet root aphid 

Recommended Product: Beaveria WP

Active ingredient: Beauveria bassiana

Sap and suck insect pests like aphids, spider mites and sugar beet root aphids are commonplaces in sugar crops, thus having a dire impact on the overall health of the plant as well as the yield of sugar. These pests consume at all times by feeding on the plant tissues by piercing and sucking out sap which weakens the plants making them less vigorous. They emit messy balls of honeydew during feeding which clings on stems and leaves. This honeydew promotes the growth of sooty mould which prevents penetration of sunlight, impairs photosynthesis and eventually inhibits stalk growth and sugar salvage.

The aphids and sugar beet root aphids are especially harmful in that they are also vectors of viral diseases thereby infecting fields at a very fast rate. Sugar beet root aphid feeds on the roots below the soil surface resulting in stunted growth, yellowing and low sugar content. Even though spider mites are not honeydew makers, they induce chlorotic speckling, bronzing of leaves, and premature leaf drying, even though they are sucking cell materials leading to low photosynthetic effectiveness, and agricultural yield.

Beveria WP is a biological insecticide for sugar beets made using entomopathogenic fungus Beauveria bassiana as an environmentally friendly substitute of the chemical insecticides with synthetic chemicals which are known to cause numerous problems in pest control. Beauveria bassiana operates by generating spore which attaches to the insect surface of the exoskeleton. Such spores hatch and pierce the insect cuticle. When the insect (hemicoel) is inside, the fungus multiplies emitting toxins and blastospores that interfere with the metabolism, drain internal nourishment and ultimately kill the insect in three to seven days.

This type of biological mode of action, despite its low speed compared to the chemical contact insecticides, supplies long-term control needs and suits well in the Integrated Pest Management (IPM) programs.

Beveria WP is most effective at the onset of the infestation so the target areas are always on the early nymph and juvenile stages where aphids and spider mites are the most susceptible. A foliar spray of 1-2 grams of water per liter should be used to cover the foliage and feeding sites on coleopteran and other stems and leaves. The sugar beet root aphids should be treated by soil drenching in the root area to ensure that the root area is destroyed. The repeated applications at 7-10 days will be used to sustain the active pressure of fungi and avoid resurrection of pests.

Beveria WP does not leave any toxic chemical residues, can be used fully in organic production systems and minimizes the chances of developing resistance since it is a biological action. The fact that it can propagate by secondary infection also increases field level suppression in the long run. As such, Beveria WP offers a workable and viable solution to the issues encountered in protecting the sugar crops against aphids, spider mites and root aphids of the sugar beets on a long-term basis.

Target Pests: Beet Armyworm, False Celery Leaftier, Beet Leafminer, Beet Moth

Recommended Product: BT Thuricide

Active ingredient: Bacillus thuringiensis (BT)

A kind of group of chewing pests that sap such as curly top Beet Armyworm (Spodoptera exigua), Beet leafminers and Beet moths, are often a threat to vegetable and field crops. These pests lead to wide spread defoliation of growing plants, tunneling in the leaf tissues, and rapid degradation of crops. Large masses of foliage are eaten in a brief time by the larvae of the Armyworms, and serpentine mines are made by leafminers, interfering with the photosynthesis. Curly top add extra damage by diffusing viral ailments that decelerate the growth and create a large decrease in yield capacity.

BT Thuricide is a biological insecticide for sugar beets composed of microorganism Bacillus thuringiensis that is a naturally occurring serial bacteria present on the soil and is commonly utilized in biological insecticidal management programs. After the ingested larvae swallow it, Bacillus thuringiensis releases crystalline proteins that connect with receptors in the insect gut, leading to the paralysis of the digestive system and the termination of feeding in a short period. The larvae perishes in a matter of days avoiding future crop devastation and still being environmentally safe.

BT Thuricide may be used most effectively when first visible population of pests, especially at the early stages of their larval development when feeding commences. The foliar sprays must cover the leaf surfaces making sure that they are full of larval feeding and hatching areas. Reapplications at 5-7 days preventive measures assist in the maintenance of active protection on the time of high infestation. As the product is ingestible, it is necessary to monitor and apply it consistently due to its consistent nature of control.

BT Thuricide does not result in any chemical residues, is non-toxic to beneficial insects and pollinators and can be incorporated effortlessly into certified organic and integrated pest management. It lacks the possibility of development of resistance and acts against the enormous collection of caterpillar pests, it offers a lasting and efficient crop protection system, which is not harmful to the ecological balance.

Target Pests: Flea Beetles (Phyllotreta spp.), Blister Beetles 

Recommended Product: Myco Pestop

Active ingredient: Metarhizium anisopliae

Phyllotreta spp and blister of beetles are believed to be among the most devastating of chewing pests, which assault vegetable crops, field and ornamental crops. Flea beetles feed on tenders of the plants and leave a proliferation of small issues in the form of shot holes on the leaves, making the plant lose the ability to produce enough food and thus early loss of crops. With heavy infestation, growth may be retarded or lead to the fully destruction of seedlings. The blister beetles are known to cause the rapid defoliation that farmers can lose large section of foliage usually in large swarms which can leave a plant naked in just a few days causing debilitating yield loss unless treated immediately.

As an alternative to the use of conventional chemical insecticide, Myco Pestop is a fungal-based insecticide, which is a biological pesticide derived by using the entomopathogenic microorganism, Metarhizium anisopliae. After application; Metarhizium anisopliae spores settle on the insect exoskeleton, germinate and invade the insect body via cuticle. The fungus then spread in the hemocoel where it releases toxins and then eats the internal nutrients of the insect leading to its death in a space of three to seven days. This biological mode of action is applied in IPM programs though it is slower acting than horticides which contain contact than giving long-term population suppression.

To ensure the best outcomes, Myco Pestop is to be used as soon as the activity of the flea beetle or blister beetle has been detected, especially in early infestation of the larva or young adult insects that are most susceptible. Complete foliar coverage will guarantee first hand contact with spores and feeding insects. Regular applications after every 7 to 10 days assist in the formation of regular biological pressure and eliminate reinfestation of pests at their peak seasons.

Myco Pestop does not leave any harmful residue, does not limit the production of organic farming systems anyhow, and offers no danger of resistance development. Its inherent property of complete secondary infection spreading further increases long-term sugar beet pest control of the fields thus it is an effective and environmentally friendly tool to controlling pests sustainably.

Target Pests:  Sugar Beet Root Maggot (Pegomya betae), Beet Seed Maggot, Weevils, Cutworms, Wireworms

Recommended Product: Met Zone    

Active ingredient: Metarhizium anisopliae 

Field crops such as sugar beets are very susceptible to various soil dwelling, root-eating, pests such as sugar beet root maggot (Pegomya betae), beet seed maggot, weevils, cutworms and wireworms. These pests destroy seeds that are just germinating or invaded roots as well as young plants resulting in poor stand establishment, wilting, tunneling and plant death. Root maggot larvae consume a lot of underground tissues making them susceptible to secondary infections and become highly malnourished. Cutworms and wireworms also exacerbate the damage by cutting seedlings at the soil line and piercing the root systems leading to great losses in terms of yields in case of uncontrolled infestation.

Met Zone is a microbial based biological insecticide for sugar beets that has been made using the entomopathic fungi Metarhizium anisopliae that is offering as the alternative to the conventional soil insecticides, sustainable. After being exposed to the soil environment, Metarhizium anisopliae spores adhere to the insect larvae and adults and enter the body by cutting the cuticle and proliferating inside the insects. The fungus secreted toxins and fed on internal tissues and insects die after three to seven days. The benefit of this biological infection process is that it provides long-term control of the pest population and solves the rapid rise which is common with the use of chemicals.

Met Zone must be sprayed to the soil upon planting or when the crop is actively growing so that the pest larva is most active. The product can be either incorporated in the soil, used as drip irrigation, or as a drench to be able to evenly sow the spores in the root zone. Repetition at high pest pressure assists in sustaining active fungal populations when the protection is required to be long-term.

Met Zone has no residual chemicals in it, it helps in maintaining helpful soil microorganisms, and head-on clashes with organic and integrated pest management programs. Having zero chances of developing resistance, it is an eco-friendly, long-term solution to destroying the crops using harmful soil insects.

Sugar Beet Leaf Diseases

Target Diseases: Cercospora Leaf Spot, Powdery Mildew, Rust, Ramularia Leaf Spot, Downy Mildew 

Recommended Product: FloraEgis  

Active Ingredient: Trichoderma harzianum   

The destructive foliar fungi diseases predominant with most crops of vegetable and field farming systems include Cercospora leaf spot, powdery mildew, rust, Ramularia leaf spot, and downy mildew. The diseases lower the capacity of photosynthesis by destroying the leaf tissue, leading to spotting, yellowing, untimely defoliation as well as weak plants. Cercospora and Ramularia cause growing necrotic spots and increase the speed of leaf fall, and powdery mildew forms patches of white fungi which strangle the exchange of gases. The spreading of rust infections by spores via the air and downy mildew grows in cool and humid environments, hence commonly causing massive crop destruction when not controlled at an early stage.

The FloraEgis is a micro-organism-derived biological sugar beet fungicides, which entails the use of a useful microorganism termed Trichoderma harzianum, which offers a mosquito-like fungicide in place of chemical-based fungicides whose use has led to environmental contamination. The activation of trichoderma harzianum is based on several biological mechanisms such as antagonism of pathologically active fungi, nutrients/colonization site competition, antifungal metabolic products as well as induction of plant defense mechanisms. The synergies of these measures will prevent disease formation as well as enhance the innate resistance of the plant to infection.

FloraEgis would work best when used preventatively or at the onset of signs of stress of the disease to develop protective microbial populations on the leaf surfaces. Foliar spraying provides even distribution of the vulnerable tissues where the pathogens trigger the infections. Frequent reapplications at times of great disease risk are used to sustain excellent biological protection and diminish disease transmission across the crop canopy.

FloraEgis has no residual toxins, has no adverse effects on living beings, fits in both the organic and integrated disease management. Being free of danger of development of resistance and having a long-term preventive effect, it can be discussed as a stable and environmentally conscious method of the sustainable control of the widespread fungal foliar diseases.

Sugar Beet Disease Control

Target Diseases: Rhizomania, Rhizoctonia Root Rot, Phytophthora Root Rot, Fusarium Yellows,  Sclerotinia Crown Rot 

Recommended Product: HarzShield

Active Ingredient: Trichoderma harzianum

Sugarbeets are incredibly sought after by the devastating soil borne infections, including rhizomania, Rhizoctonia root rot, Phyto root rot, Fusarium yellows and Sclerotinia crown rot. These pathogens strike against roots and the crown tissues causing the interference with the uptake of water and nutrients and causing wilting, yellowing foliage, slow growth and marked reduction of yield. Rhizomania leads to excessive branching of roots and lack of sugar accumulation whereas Rhizoctonia root rots, Phytophthora rots cause tissue decline and plant death. Fusarium yellows limit the circulation of all vascular systems, and brings plants down during the growth period and Sclerotinia crown rot propagates rot during cool and wet seasons.

HarzShield is a biologic disease control product that is developed with a benefit fungus Trichoderma harzianum providing an alternative to chemical fungicide for sugar beets as a sustainable sugar beet pest control method against complicated soil-borne pathogens. Trichoderma harzianum interacts in several ways; colonizing the root zone, competing with pathogenic fungi on space and nutrients, synthesizing anti-fungal molecules and also directly parasitizing disease-causing fungi. This multi-action technique kills pathogen growth and enhances healthier roots and increased vigor of the plants.

HarzShield must be applied at the root zone or early stages of crops when they are in optimal condition to ensure that pathogens remain dormant until all the microbial populations are in a healthy state. The product may be added into soil, the irrigation system applied, or the seed and root-zone treatment should be applied to guarantee an even distribution all over. The persistence of the application in the conditions of high disease pressure contributes to the preservation of good biological barriers in the face of the disease.

HarzShield also does not leave any chemical traces behind, and it improves the microbial balance of soil and it easily fits into the organic and integrated disease management programs. Having no threat of pathogen resistance and long-term protection benefits of the root, it is an adequate environmentally sound solution to the sustainable sugar beet disease control​.

Target Diseases: Bacterial Blight

Recommended Product: Bactonus      

Active Ingredient: Bacillus safensis, Bacillus velezensis, and Pseudomonas chlororaphis

The sugar beet bacterial diseases​ blight has been extremely destructive on numerous field and vegetable crops. It brings about spotting of leaves, water filled holes, streaking on stems as well as infections of fruits, which eventually result into decreased plant vigor, retarded growth and high fruit losses. Plants that are infected, tend to develop rapid tissue necrosis and early leaves fall, which aids in the further transmission of the pathogen in and without the field. The control of bacterial blight is especially a hard task as the conventional chemical bactericides are not very effective and their frequent application can affect the health of soil and the useful populations of microbes.

Bactonus is a biologically-based disease control product developed as a consortium of useful microorganisms: Bacillus safensis, Bacillus velezensis and Pseudomonas chlororaphis. These microbes are part of nature, they are biological antagonists of pathogenic bacteria in more than one way, such as competition both in nutrients and colonization sites, antimicrobial compounds, as well as development of systemic resistance in the host plant. This poly-layered mechanism of action reduces bacterial growth, improves plant defense and reduces disease severity and oftenness without the presence of chemical residues.

To do this best, Bactonus needs to be used as soon as bacterial blight symptoms appear or as a preventive against infection in areas with a prior history of infection. Foliar sprays make sure the targets have been covered, including leaves, stems, and fruit surfaces on which the pathogens begin colonizing. Periodic repeat applications retain active populations of microbes and support disease suppression over the growing season.

Bactonus does not develop any harmful residual, is fully compatible with organic and integrated disease management programs and is not related to the development of resistance. Its application promotes the healthy growth of crops on long-term basis, the presence of soil microbes, and the sustainable control of bacterial bait, which provides growers with the solution of good quality and productivity of crops as an environmental friendly aspect.

Target Diseases: Verticillium Wilt, Blackleg

Recommended Product: Cropium

Active Ingredient: Penicillium bilaiae

Soil-borne diseases in the vegetable, brassica and root crop, mainly include the Verticillium wilt and Blackleg. Verticillium wilt assacks vascular tissues making the leaves yellow, wither, unproductive and death of the plant. The symptomatic results of Blackleg are mainly stem and sugar beet root diseases attack which results in cankers, rot and poor establishment of stands. The two diseases are contagious and can easily be transmitted to adjacent soils, irrigation water, and infected plant debris which can lead to massive losses in yield, in case it is not controlled at an early stage. The absence of microbial and other beneficial soil life may characterize traditional chemical methods in which people assume control yet cause harm to the soil.

Cropium is a biological disease control product containing a useful fungus Penicillium bilaiae, which appears to be a sustainable and organic disease suppressant after being used on soils. Penicillium bilaiae helps to make plants more resilient by enhancing nutrient availability through colonization of roots in the rhizosphere, and by enhancing plant defense against pathogenic fungi and bacteria. Its activity stimulates the development of good root systems and controls the severity of diseases that enable crops to recover and grow under the influence of pathogens.

To achieve maximum effects, Cropium is needed to be applied to soil at planting or at the formative stage of crop development to ensure beneficial microbial populations are developed in the root zone before the attack of pathogens. Its uses include the product being applied as a drench to the soil, in irrigation systems or in seedling trays to provide protection at an early stage. Frequent uses in the high pressure areas may also contribute to long term disease repression and the vitality of plants.

Cropium is entirely organic and integrated crop management programs, and there are no chemical residues and it promotes soil microbial diversity. Also, as there is no threat of resistant development, it offers a good, ecologically friendly option to rectify Verticillium wilt and Blackleg besides producing healthier, stronger crops.
