Bacillus thuringiensis subsp. Kurstaki strain ABTS-351

Bacillus thuringiensis subsp. Kurstaki strain ABTS-351 is a highly specialized biological insecticide that utilizes specific strains of bacteria to manage pest populations. It is widely recognized in the agricultural sector as a cornerstone of Integrated Pest Management (IPM) due to its high selectivity and low environmental impact.

The primary mode of action relies on the production of crystalline proteins known as endotoxins during the bacterial sporulation process. When ingested by susceptible larvae, these crystals are dissolved in the alkaline environment of the insect's midgut, causing the gut wall to rupture. This leads to the cessation of feeding within hours and subsequent death of the larvae.

This strain is effectively used across a vast range of crops, including vegetables, fruit trees, and ornamental plants. It is particularly potent against Lepidopteran pests such as cabbage loopers, tomato fruitworms, codling moths, and various leafrollers. By targeting specific digestive systems of these pests, the substance ensures that beneficial insects remain unaffected.

Application strategies focus on achieving thorough coverage, as the insect must ingest the treated foliage. It is critical to apply the product during the early stages of larval development for maximum efficacy. Furthermore, because the active proteins are sensitive to degradation by UV rays, application during late afternoon or cloudy conditions is highly recommended.

• Ensures high efficacy against early larval instars (first to third instar).
• Allows for a short pre-harvest interval due to its low toxicity profile.
• Can be integrated with other biological and chemical control methods to improve sustainability.

Safety precautions are straightforward but essential: protective gear such as gloves and masks should be worn during handling to prevent skin and respiratory irritation. The product should be stored in a cool, dry place away from direct sunlight to preserve the integrity of the bacterial spores. Always consult local regulations regarding the specific dosage rates and environmental safety guidelines.
