目前我国农药品种结构上存在的主要问题是杀虫剂比重偏大,除草剂比重偏小。我国每年由于草害所造成的损失占全国农作物总量的10％以上,超过了虫害和病害。 最近几年的农药需求总量基本稳定在21万吨左右,据测算,我国每年水稻虫害防治面积7亿亩次,需农药4.5万吨;棉花虫害防治面积5.1亿亩次,需农药3万吨;小麦虫害防治面积2.2亿亩次,需农药约1.7万吨;其他害虫防治面积6.6
At present, the main problems in the structure of pesticides in China are the large proportion of pesticides and the small proportion of herbicides. China’s annual loss due to grass damage accounts for over 10% of the country’s total crops, which exceeds pests and diseases. The total amount of pesticide demand in recent years has basically stabilized at about 210,000 tons. According to calculations, China annually controls 700 million mu of rice pests, requires 45,000 tons of pesticides, controls 510 million mu of cotton pests, and requires 30,000 tons of pesticides. ; Wheat pest control area of 220 million mu, requires about 17,000 tons of pesticides; other pest control area 6.6
