摘要
本试验采用粮食边入库边用防虫磷机械喷雾的方法,利用冬季自然低温,结合机械通风降温,减少药剂用量来延长对害虫的有效防虫期,降低费用及粮食中药剂残留量。试验结果表明:防虫磷剂量为20mg/kg时结合机械通风降温对玉米象有效防治期为9个月以上,对谷蠹为6个月以上,比不通风仓防治玉米象和谷蠹可节约防虫磷用药量33％～50％。
The test was carried out under the condition of putting the grain into the warehouse while malathion spraying, making use of natural low temperature in winter and mechanical ventilation to lower temperature, using low dose of malathion in order to prolong the control period, reduce costs and residue in grain. The results showed that combination of 20mg/kg malathion with mechanical ventilation could control effectively Sitophilus zeamais for more than 9 months, Rhyzopertha dominica for more than 6 months. 33％—50％ dose was reduced compared with warehouse without ventilation.
