Blossom End Rot in Tomatoes: Causes, Prevention, and Treatment

Tomato growers know all about this disturbance called Blossom End Rot (BER) and I’ve been no exception given my years of gardening experience. It is an unrelenting problem that not only defeats our crops' productivity but also significantly limits the quality of our crops. In this regard however there is new hope provided by new biological treatments especially when using fungi such as Trichoderma harzianum and bacteria such as Bacillus subtilis. These innovations offer the potential for these approaches to address this common issue. In this blog, I’ll let you know what causes blossom end rot on tomatoes​ and tomato blossom end rot treatment​.

What causes blossom end rot on tomatoes?

Blossom End Rot, also called tomato plants bottom rot, is a physiological disorder of tomato, which is characterized by black or dark sunken appearance at the blossom end of the fruit. This condition is mainly precipitated by low levels of calcium in the body. Among them, fluctuating climate conditions and inadequate state of the soil inhibit the uptake of calcium in the plant. It is therefore important to identify these warning signs in the early stages to prevent lots of loss of crops and poor production.

What causes this problem?

Several factors contribute to the development of Blossom End Rot in tomatoes:

1. Calcium Deficiency: The main proximate cause is calcium defecit, which is attributed to erratic irrigation regimes that allow calcium, which is an important nutrient to be inadequate in the plant.
2.  Environmental Stress: Both temperature changes and moisture stress add extra pressure to the plant physiological processes deepening the problem.   
3.  Root Health: Nutrient uptake is significantly influenced by either poor root development of rot and is often deficient in nutrients which in turn causes Blossom End Rot.

How to prevent blossom end rot in tomatoes?

Tomato blossom end rot treatment involves a multi-faceted approach:

1. Soil and Water Management: Keeping the right fertility and pH of the soil should be observed. Regular and thorough watering avoids water stress on the plants and adding mulch has the effect of stabilizing the temperature in the root zone and reducing such effects as rapid evaporation of moisture from the soil surface.
2. Use of Biological Agents: Working with the specialists in microbial agriculture I realized that the biological agents are incredibly helpful in aspects of garden care:   

          -Trichoderma harzianum: This beneficial fungus increases the percentage of root vigor and the calcium nutrition through triggering plant resistance and favorable microbial activities in the rhizosphere.
          -Bacillus subtilis: This bacterium is associated with increase in soil fertility, increases root mass, and suppresses soil-borne diseases. This enhances calcium uptake and strengthens plants to cut on root injury and hence, lowering chances of B.E.R.

Tomato Blossom End Rot Cure: Usage of Biologicals

Tomato blossom end rot can be controlled with products containing Trichoderma harzianum and Bacillus subtilis, through soil drenches, foliar spray or seeds. It is therefore important to ensure that through the time of application, the method adapts fully and harmonizes with what is commonly associated with horticulture.

A Sustainable Approach to Managing Tomato Blossom End Rot

It, therefore, stands out clearly that effective tomato blossom end rot treatment​ need not result in the agriculture industry resorting to chemical control measures but rather through combining the two byilian trap biological control agents such as Trichoderma harzianum and Bacillus subtilis with cultural practices. It is my considered opinion that fellow gardeners and farmers should try these bio-products to boost the standing of crops and to increase the effectiveness of sustainability in farming techniques. The integration of based experience of gardening with vital scientific research constitutes an excellent model of healthy crop production and bumper yields, unmarred by the menace of Blossom End Rot.
