据记者近日调查,我国许多水稻种植地区虫害较去年普遍发生较轻,一些地区农民往年每周用药一次,而今年至少要两周时间才用一次药。虫害的减少给杀虫剂的市场销售带来不利影响。虽然受虫害较轻影响,但低毒且对环境友好的常规杀虫剂甲维盐却没有因此而现颓势,各地甲维盐用量仍较大。 According to a recent survey by reporters, pests in many paddy planting areas in our country have generally occurred less than last year. In some areas, peasants once took medicine once a week in previous years, and this year, at least two weeks before using it once. The reduction of pests has adversely affected the marketing of pesticides. Although less susceptible to pests, the low toxicity and environmentally friendly conventional carbaryl salt did not show any signs of decline and the salt consumption in each dimension was still high.
