砻糠载体不均匀施药技术的研究

选择多种物料作为防护剂载体,以马拉硫磷10ppm处理玉米象,以砻糠效果最好,其次按顺序为小麦、聚乙烯树酯、毛竹、天竺竹、松木、梓木、聚氯乙烯树酯。砻糠载体法比常规的喷雾法或药谷法对玉米象和谷蠹效果好。在粮食中残留始终很低。同时发现粮层厚度30厘米以内间隔施药药效好。生产性试验表明随粮食边入库边撒药糠的不均匀施药法是可行的,革除了旧法施药后彻底搅拌粮食的笨重体力劳动,提高了施药和食用安全程度。

RESEARCH OF RICEHUSK-CARRIER METHOD AS NON-UNIFORM TREATMENT WITH MALATHION

Various protectant carriers were evaluated,using malathion 10ppm treatment,which was tested on it''s effectiveness against Sitophilus zeamais.Rice husk showed the best results,the order of effectivenessfor the rest was wheat,polyethylene,moso bamboo,tianjur bamboo,masson pine,Chinese catalpa and polyethylene chloride.The rice-husk-carrier method had better persistant effectivenessand lower residue levels than the general spraying method.Also,it wasfound that a thirty centimeters protectant layer produced good effective-ness.Full scale trials showed that nonuniform treatment by the ricehusk-carrier method produced adequate results.There was no need formixing whole bulk of grain as in the spraying method,so doing awaywith hard work.
