首先,我们为农药药害界定一个概念,即什么是农药药害?其范围是,若使用农药方法不当,技术要求控制不严,不但不能达到杀虫、防病、除草、调节作物生长的效果,还能引起被施药的农作物或种子发生不正常的生长发育及生理症状、质量下降等。如出现落叶、落果、叶子变黄、严重叶斑、凋萎、灼伤、矮化、生长缓慢、畸形、徒长乃至枯萎或植株死亡或种子发芽率降低等症状,便可称为药害。
First of all, we define a concept of pesticide injury, that is, what is pesticide injury? The scope is that if pesticides are improperly used and the technical requirements are not properly controlled, insecticide, disease prevention, weeding and crop growth regulation can not be achieved , But also can cause the crop or seed to be administered to have abnormal growth and physiological symptoms and quality degradation. Such as the emergence of deciduous, deciduous, yellow leaves, severe leaf spot, wilting, burns, dwarfing, slow growth, deformity, leggy or even withered or plant death or seed germination rate and other symptoms can be called injury.
