为了抗御不断发生的抗性和取代那些高毒、高残留和对环境有不良影响的农药品种,开发具有新颖结构和作用机制的新农药品种也是一个重大措施。尽管一批批新的农药品种不断问世,但人们仍孜孜不倦地研发新的具有农药活性的化合物。本文收集了26个正研究的新结构的农药化合物,其中,杀菌剂10个,除草剂9个,杀虫剂7个。以下分别予以介绍。 The development of new varieties of pesticides with novel structures and mechanisms of action is also an important measure in order to combat the ongoing resistance and to replace those highly toxic, high-residue and environmentally unfriendly pesticides. Although a batch of new varieties of pesticides continue to come out, people are still tirelessly developing new pesticide-active compounds. Twenty-six new pesticides are being studied, including 10 fungicides, 9 herbicides and 7 insecticides. The following were introduced.
