农业的可持续发展越来越受到重视,这直接影响到化学农药的发展趋势。可持续发展农业的特点要求21世纪的化学农药向“环保型”发展,即必须具备“三高”的特点:第一是高性能。过去每一单位面积耕地的农药有效成份用量几十克甚至上百克,现在许多新品种使用量降到几克甚至不到1克,从发展趋势看,可能还会出现效率更高的化合物。第二是高安全性。整个社会对农药的安全评价要求越来越高,因此农药必须达到既能防治病虫草害,又不能对人畜安全造成损害的标准
The sustainable development of agriculture is getting more and more attention, which has a direct impact on the development trend of chemical pesticides. The characteristics of sustainable agriculture require chemical pesticides in the 21st century to “green” development, which must have “three high ” features: The first is high performance. In the past, the effective amount of pesticide per unit area of cultivated land was tens or even hundreds of grams. Nowadays, the usage of many new varieties is reduced to several grams or even less than 1 gram. From the development trend, more efficient compounds may appear. The second is high security. The society as a whole needs to evaluate the safety of pesticides more and more. Therefore, pesticides must meet the standards that can both prevent pests and weeds without compromising the safety of human beings and animals
