1975年湖北省沔阳县下查埠公社,于棉铃虫棉田二,三代发生期间,进行了大面积棉叶喷过磷酸钙驱避棉铃虫产卵的效果试验。喷磷面积共12,878亩占公社棉田的63.9‰,据多点调查的百株卵量结果,在棉田二代棉铃虫发生期间,喷磷区4383亩,均在防治标准百株卵量十粒以下,而对照未喷磷的15,717亩,有57.5%的面积达到除治标准。棉田三代棉铃虫发生期间,喷磷区8490亩,达到防治标准的面积占59.1%,而对照区11,610亩达86.4‰说明棉叶喷磷有较显著的驱避棉铃虫产卵的效果。
In 1975, Hubei Province, Xuyang County Xia Cha port commune, cotton bollworm cotton fields occurred during the second and third generation, carried out a large area of cotton leaves sprayed with calcium phosphate to repel cotton bollworm spawning effect test. According to the results of more than 100 eggs surveyed, during the occurrence of the second generation cotton bollworm in the cotton field, 4383 mu of phosphorus spraying area was under the standard of prevention and control of one hundred eggs , While the control did not spray phosphorus 15,717 mu, 57.5% of the area to reach the standard in addition to governance. Cotton bollworm occurred during the three generations, 8490 acres of phosphorus spray area, to control the standard area accounted for 59.1%, while the control area of 11,610 acres reached 86.4 ‰ that cotton leaf phosphorus spray more significantly repel cotton bollworm spawning effect.
