为探索防治棉铃虫的新途径,我所在试验研究用久效磷缓释剂涂茎防治棉花苗蚜的基础上,于1979、1980两年进行了涂茎防治棉铃虫的试验示范,取得了较好的效果。为进一步验证其成效,1981年在聊城以聊城镇为中心搞了近万亩样板。大面积生产实践证明,涂茎防治棉田一代棉铃虫效果明显,切实可行。配制容易操作简便久效磷缓释剂系久效磷内吸剂加聚乙烯醇为缓释剂按一定比例配制而成。久效磷为山东省青岛农药厂生产,固体聚乙烯
In order to explore a new way to prevent and control the cotton bollworm, my experimental study of the use of monocrotophos slow-release agent coated cotton seedling control aphids on the basis of cotton stem bollworm in 1979 and 1980 two years pilot demonstration and achieved more Good results. To further verify its effectiveness, in Liaocheng in Liaocheng in 1981 as the center engaged in nearly mu model. Large-scale production practice has proved that the cotton seedling control cotton bollworm effect is obvious, feasible. Preparation of easy and easy to operate monocrotophos slow release of long-acting phosphorus in the agent plus polyvinyl alcohol as a sustained-release agent formulated according to a certain percentage.
