First, it is non-toxic to humans and animals and safe to use. The protein toxin of Bt bacteria does not play a role in the gastrointestinal tract of humans and livestock and poultry. Second, the selectivity is strong and does not harm natural enemies. Bt bacteria only specifically infect certain types of insects and protect natural enemies. Third, it is a clean pesticide that does not pollute the environment and does not affect the activities of soil microorganisms. Fourth, continuous use will result in the epidemic area of ​​pests, resulting in widespread spread of pest pathogens and achieving the goal of naturally controlling insect population density. Fifth, there is no residual poison, the products produced can be safely eaten, and at the same time, the color and flavor of vegetables and fruits are not changed. sixth. It is not easy to develop resistance, which is only relative. The struggle between humans and harmful insects is extremely difficult and complicated. Recently, reports of drug resistance have been discovered, but not as fast as chemical pesticides .
Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
