Avoiding resistance - We need to maintain the susceptibility of pests in order to prolong the useful life of pesticides

摘要

When a grower notices that a pesticide no longer works as efficiently as it did in the past, it is likely that the grower is experiencing pesticide resistance, barring errors related to spray rate and coverage. It is estimated that worldwide, more than 500 species of insects and its relatives have shown resistance to at least one class of insecticides. Given the difficulty and cost of developing and registering new pesticides, we need to make every effort to minimize the development of resistance inthe products that we currently have. That is, we need to maintain the susceptibility of pests in order to prolong the useful life of pesticides.
