Microbial Solution For Tomato Pests and Diseases


Tomatoes form one of the many key crops in world farming and are prone to a number of pests, viruses etc. Well management is the key to health plants and good crops. This manual covers all the important and troublesome tomato pests, diseases causing wilting of tomatoes plants as well as ways to control them.

Tomato Pests

Tomato Hornworm (Manduca quinquemaculata) Tomato Pests 


Symptoms and features: The Hornworm, a notorious tomato pest, can grow up to 4 inches long. These caterpillars are easily identified by their bright green color, V-shaped markings, and a prominent horn on their rear. They are voracious eaters, primarily targeting the upper parts of tomato plants, causing severe defoliation and even attacking the fruit. 

Management: Effective management strategies include diligent plant inspection for early detection and handpicking the larvae. Biological control methods, such as introducing natural predators like birds and parasitic wasps, are beneficial. For organic control, Bacillus thuringiensis (Bt), a naturally occurring soil bacterium, can be applied to infested plants, effectively targeting the larvae while being safe for other wildlife and the environment.

Solution:   To address Tomato Hornworm issues, employ BT Thuricide, a formulation of Bacillus thuringiensis. This biological approach offers a sustainable and effective alternative to synthetic insecticides.

Whiteflies (Bemisia tabaci)


Symptoms and features: Whiteflies are tiny, white-winged insects that swarm in large numbers, particularly on the undersides of tomato plant leaves. These pests feed on the sap of the plants, leading to chlorosis (yellowing of leaves), tomato plant wilting, defoliation, and overall stunted growth.

Management: Managing whiteflies involves regular monitoring with yellow sticky traps to detect and reduce their population. Encouraging natural predators, such as ladybugs, can provide biological control. 

Solution:   For managing whitefly infestations, Beveria WP and Beauveria Bassiana serve as natural fungal biocontrol agents. These environmentally conscious options effectively diminish whitefly numbers, bypassing the need for chemical pesticides.

Spider Mites (Tetranychus spp.)
