蔬菜主要病虫害有100多种,在防治方面除引导菜农选用抗病虫丰产良种,合理布局品种,实行轮作倒茬等农业技术措施外,目前主要靠施用化学农药进行防治。由于蔬菜生育期短,大部分蔬菜收获后即被食用,有的甚至生食。因此,它要求菜田所用农药具有高效低毒低残留之特性,现依据我们的试验和所查资料,系统地将菜田常用农药品种、主要防治对象、使用方法、用药量等总结归表于后,以便指导菜农科学合理用药,为市场提供更多无农药污染蔬菜,保证人民身体健康。
There are more than 100 kinds of major diseases and pests in vegetables. In the aspects of prevention and control, in addition to guiding the vegetable farmers to use resistant and worm-resistant high yielding varieties, rationally arranging varieties and implementing agricultural technical measures such as crop rotation and stubble, chemical pesticides are mainly used for prevention and control. Due to the short growth period of vegetables, most of the vegetables are consumed after harvest, and some are even eaten raw. Therefore, it requires that the pesticides used in vegetable fields have the characteristics of high efficiency, low toxicity and low residue. Based on our tests and the data collected, it systematically summarizes the common pesticide varieties, main control objects, methods of use and dosage in vegetable fields After that, in order to guide the vegetable science and rational use of medicines, to provide the market with more pesticide-free vegetables to ensure healthy people’s health.
