化学农药的使用对农业稳产、高产起到了良好作用。据统计,如果停止使用农药,农作物收获量的一半将被病、虫、草、鼠所吞噬。目前,世界每年被老鼠遭踏的粮食约占总产量的五分之一,仅亚州就损失稻谷4800多万吨,足够2.51亿人吃一年。另外,农药在卫生防病方面作用也是很大的。 The use of chemical pesticides has played a good role in agricultural stable production and high yield. According to statistics, if you stop using pesticides, half the amount of crops harvested will be disease, insects, grass, rats swallowed. At present, every year the world is deprived of food by rats accounts for about one fifth of the total output. Only Asia lost more than 48 million tons of rice and 251 million people a year.
