Sun bio Bt is a natural and non pathogenic pesticide containing (Bacillus thuringiensis) as an active ingredient. (Bacillus thuringiensis), commonly known as Bt, is a bacterium that occurs naturally in the soil and it is safe for non target insects and animals. Having a UV Protectant, the product is effective for a longer period in the field. The most significant benefit of SUN BIO Bt is the reduction in insecticidal usage for the control of bollworms. Once ingested by larval insect, it releases toxic crystal which destroys digestive system of insect and enters into blood stream causing death of insect due to blood poisoning.
