农药是植物保护的重要手段,但农药抗性是一个不可忽略的问题。最近报道,在251种引起作物及储粮损失的真菌中,只有27种真菌分别对一类杀菌剂有严重抗性,用相对应类别的杀菌剂防治时会造成重大的损失,有时损失殆尽。尽管如此,人们并未丧失对这些病菌造成病害的控制,因为对此可用不同作用机制的杀菌剂来防治。杀虫剂、除草剂的情况也如此,这说明成功的抗性管理依赖于新作 Pesticide is an important means of plant protection, but pesticide resistance is a problem that can not be neglected. It has recently been reported that out of 251 species of fungi causing crop and grain losses, only 27 are highly resistant to one type of fungicide, respectively, causing significant losses and sometimes loss of control with the corresponding classes of fungicides . In spite of this, there is no loss of control over the disease causing these germs, for which fungicides with different mechanisms of action can be used for prevention. The same is true for pesticides and herbicides, suggesting that successful resistance management relies on new work
