新的化合物是否可作为农药而具有实际效用十分重要的是要进行室内药效试验,并要考虑到其化学稳定性、蒸散性、溶解性、吸附性等物理化学特性及与病虫的生理生态相适应的施用方法,然后进行综合性的判断。而农药试验农场可就上述与农药实用性有关的种种因素进行综合的评价。另外,通过农场试验还能发现室内试验难于判断的杀虫、杀菌剂的残效或迟效特性。除此之外,许多事例表明,田间试验还能对药剂的增产、减产效果及药害等副作用作出评价。因此,田间试验是促进研制新农药必不可少的试验阶段,人们对它的重要性的认识正在提高。
It is important that new compounds have practical utility as pesticides for indoor efficacy testing, taking into account physicochemical properties such as chemical stability, evapotranspiration, solubility, adsorption, Adapt to the application method, and then make a comprehensive judgment. However, the pesticide testing farm may comprehensively evaluate the above factors related to the practicability of pesticides. In addition, farms can also be found through laboratory tests difficult to determine the indoor test insecticide, fungicide residues or delayed characteristics. In addition, many examples show that field trials can also evaluate the side effects of pesticide production, yield reduction and phytotoxicity. Therefore, field trials are an indispensable experimental stage to promote the development of new pesticides. People’s awareness of its importance is on the rise.
