作者用山东农药厂出品的40%敌敌畏乳剂,燻蒸防治大米、小麦仓庫害虫(米象、米出尾虫、米黑虫、拟谷盗、鋸谷盜等)。从試驗結果可以看出:一、敌敌畏渗透能力很差。包装米渗透可达三十至四十厘米,散装米仅能达二十厘米。因此,仓庫儲粮大規模燻蒸时敌敌畏并不是理想的药剂。但是由于它使用方便、安全,对少量粮食、标本样品等另星东西,还是可以应用的。对数量較多的粮食,先将药液噴洒在麻袋或蘆席上,然后将粮食薄摊,厚度不超过二十厘米;数量更多的粮食,可采用探管
The author uses Shandong pesticide plant produced 40% dichlorvos emulsion, fumigation control of rice, wheat warehouse pests (rice elephant, rice tail insects, rice black worms, to be cereal, Saw Valley Pirates, etc.). It can be seen from the test results: First, the ability to penetrate dichlorvos is poor. Packed rice infiltration of up to thirty to forty centimeters, bulk rice can only reach twenty centimeters. Therefore, the large-scale storage of grain storage fumigation Dichlorvos is not an ideal agent. However, due to its ease of use and safety, it can still be applied to other food items such as small quantities of food and specimen samples. For larger quantities of food, spray the liquid first on the sacks or on the mat, and then thin the foodstuff at a thickness of no more than twenty centimeters. For more food, use a probe
