What is the resistance of pesticides?
When pests become genetically adapted to pesticide and are no longer affected by its use, the condition is known as pesticide resistance. Studies suggest that more than 500 pest species have developed resistance to pesticides. The situation is often caused by the same classes of pesticides, which are repeatedly used for a significant time; The pests gradually create tolerance that passes into their genetic structures.
The genetic composition is the key to pesticide resistance. When pesticide is released on the tract of Earth, it is only natural that some pests will be killed and some will survive. The survivors then reproduce - and pests tend to reproduce at an extremely high rate - resulting in offspring that share the same genetic make -up as their progenitors. With each consecutive generation of offspring, this genetic composition will only become enlarged, eventually leading to the development of the whole type of adap pestration. The natural reaction is to use a larger amount of pesticide in the hope of killingThe pest. However, it turned out that this is a very ineffective way, because other pesticides of the same class only help pests to develop stronger and stronger resistors.
pesticide creators define pesticide resistance in a slightly different - but important - way. Industry does not call it resistance to pesticides; They called it resistance in the field. In the field resistance, pesticide is only associated with pesticide failure. The industry basically says that if a better product was used, pests would not develop resistance.
There are several specifications that have become resistant to different types of pesticides. Some fruit flies in the United States have cultivated resistance to pesticide malathion. In the UK, some rats have adapted to rats poison and can receive larger and larger amounts without effect. Colorado -Brambor beetle has built an extremely high tolerance to a certain PEsticides: Studies show that resistant insects are resistant to more than 50 types.
To fight the resistance of pesticides, experts propose to use another class of pesticides. However, research has emerged and said it could be difficult because the pesticides used in rotation are harder and heavier. In the short term, however, a new class of pesticides may probably be a small amount of progress in the management of pests.
