Beta-Bak, the flagship product of DSC Lab, has established itself as a market leader, consistently topping sales charts, including being Karabos Natural Farming's best-selling product in 2023 amongst their extensive range of over 100 offerings.
This highly effective Bt microbe specifically targets bollworms, delivering exceptional results for farmers.
Developed by the esteemed Prof. Steyn, the isolation of this unique bacterium adds another layer of prestige and value to the Beta-Bak offering.
Furthermore, it boasts a crucial L-registration, officially recognized as an Agricultural Remedy. This rigorous certification underlines the product's safety and efficacy.
Beta-Bak's potential extends far beyond its current application. While currently registered for citrus, it has also demonstrated effectiveness against Bollworm on maize, soybeans, sunflowers, and grain sorghum. However, data gaps have hindered its registration for these additional crops.
Despite this temporary setback, extensive research is ongoing to bridge these gaps and unlock Beta-Bak's full potential across a wider range of agricultural applications.
Beta-Bak represents a groundbreaking innovation in the field of agricultural remedies. Its unique properties, proven effectiveness, and ongoing development make it a valuable asset for farmers seeking sustainable and successful crop protection.

Description: Biological insecticide for the control of American bollworm larvae (Helicoverpa armigera) on crops as specified.
Description: Biological insecticide for the control of American bollworm larvae (Helicoverpa armigera) on crops as specified.
Mode of action: BETA-BAK becomes systemic in the plant after seed or foliar application. The endotoxin crystals are produced inside or on the plant tissue where it will be consumed by larvae as soon as they hatch. Larvae stops eating within 48 h and die as a result of the leaking of gut fluids.

Results: Beta-Bak persisted longer than the biological standard and after two to three weeks Beta-Bak outperformed the biological standard after a single application. Beta-Bak was applied curative, after bollworm was detected. The recommended application of Beta-Bak is a preventative application that ensures quicker results.
