随着农业现代化的进程,应用农药防治农作物病虫害的范围越来越广。但是农药是一类毒剂,它的应用是一项技术性很强的工作。农药种类繁多,目前常用的就有百余种,如果使用不当,不但达不到预期的防治效果,甚至发生人、畜中毒,危及生命安全和对植物发生药害、污染环境等不良后果。据资料,全世界近年来每年约有200万人因接触农药而引起中毒,其中死亡约在4万人以上。为了合理、安全、经济、有效地使用农药,针对目前农药使用中存在的问题,我们从本期起开辟了“农药使用技术”讲座,供大家学习和参考。
With the process of agricultural modernization, the scope of applying pesticides to prevent and control crop diseases and pests has become wider and wider. But pesticides are a type of poison and its use is a highly technical job. There are a hundred kinds of pesticides currently used. If used improperly, they will not only fail to achieve the expected results of prevention and treatment, but may even cause human and livestock poisoning, endangering the safety of life, and causing harmful effects on plants and environmental pollution. According to statistics, in the world each year, about 2 million people are poisoned by pesticide exposure each year, of which about 40,000 are dead. In order to rationally, safely, economically and effectively use pesticides, we have opened a lecture on “Pesticide Use Technology” for the current study and reference for the existing problems in the use of pesticides.
