1974年我站用镇江农药厂提供的25％螟铃畏可湿性粉剂,在秦南公社商侍、秦北、关陈、灯塔大队和楼王公社新沟大队进行治螟试验。小区试验主要有药效观察、不同用药量、不同用药时间、不同用药方法、药剂持效期观察等五项,每小区面积0.2—0.3亩,部分项目采用大田防治比较结合大面积防治示范,用药面积计623.7亩(其中防治一代二化螟280亩,防治二代三化螟26.2亩,防治二代二化螟123.5亩,防治三代三化螟194亩),主要是检查杀虫保苗(或保穗)效果。同时观察对其它病虫的兼治作用。试验和示范均以大面积常用治螟农药1.5％甲基1605、3％666混合粉(简称甲六粉)以及25％杀虫脒水剂和不用药为对照。结果如下。
In 1974, I used the pesticide factory in Zhenjiang, Peking 25% RBW WP, Qinshan commune paternity, Qin North, Guan Chen, the Lighthouse Brigade and Lou Wang commune Xingou brigade to deal with the stem borer test. Community trials are the efficacy of observation, different doses, different medication time, different methods of drug use, drug retention period observed five, each plot area 0.2-0.3 acres, some projects using field control combined with large-scale prevention and control demonstration, medication An area of 623.7 acres (of which prevention and control of a generation of stem borer 280 mus, prevention and control of two generations of Borer borer 26.2 mus, prevention and control of 123.5 acres of second generation stem borer, prevention and treatment of three generations of borer 194 acres), mainly to check insecticidal seedling (or Spike) effect. At the same time observe the role of both pest and disease. Tests and demonstrations are commonly used in a large area of rice borer pesticides 1.5% methyl 1605,3% 666 mixed powder (referred to as A powder) and 25% of the insecticide amidine water agent and no medication as a control. The result is as follows.
