农药治虫是农作物保产的必要措施。根据近来研究的结果,有的农药除了治虫保产之外,还能促进作物生长,提高产品质量,增加产量。但是由于长期使用,或由于滥用农药,害虫产生了抗药性,降低了治虫效果,形成治虫不保产,因此,农作物遭受虫害损失,需要研究对策,预防抗性的产生,克服抗性,充分发挥农药的保产增产效益。 Pesticide pest control is a necessary measure for crop protection. According to recent research results, some pesticides in addition to pest control, but also to promote crop growth, improve product quality and increase production. However, due to long-term use, or due to the abuse of pesticides, pests have become resistant, reducing the effect of pest control, the formation of insects do not maintain production, therefore, crops suffer pests, the need to study countermeasures to prevent the emergence of resistance to overcome resistance and give full play Pesticide production increase efficiency.
