我省自1953年起,开始大量使用化学农药防治农作物病虫。由于化学农药有效果高、见效快、使用方便等显著的优点,因此发展异常迅速。据统计,1957年我省化学农药年销售量比1952年增加30.4倍,而1970年和1972年销售量分别比1952年增加330倍和408倍。化学农药的使用在农作物病虫害防治中曾起了较大的作用,化学农药防治作为一项救急性措施,在今后的病虫害综合防治的体系中,仍将会占有不可忽视的地位。
Since 1953, our province has started extensive use of chemical pesticides to control crop pests and diseases.

According to statistics, in 1957, the annual sales volume of chemical pesticides in our province increased 30.4 times compared with 1952, while the sales volume in 1970 and 1972 respectively increased 330 times and 408 times than that of 1952. The use of chemical pesticides has played a greater role in the prevention and control of crop pests and diseases. As a rescue measure, chemical pesticide control will still occupy a place of neglect in the future comprehensive pest management system.
