一、前言绿豆是我县除小麦外最大的杂粮品种,每年收购上千万斤,库存大、外调任务重。绿豆象为害极其严重,被害率达30—40%,有的高达70%,重量损失10—15%。民间储藏在坛、缸、袋内的少量绿豆和豇豆,也深受其害。历年来,我们都是在收购完毕后进行高剂量熏蒸,用药多,杀虫不彻底,药剂浪费严重而且由于熏蒸不及时,虫蚀率高,死虫密度大,外调常常降级降等,造成经济上的损失不小。去年,我们进行了微量磷化铝间歇熏蒸旱期防治绿豆象的试验,对保证商品质量,提高经济效益有很好的效果。试验证明:每万斤绿豆用磷化铝片剂 First, the preface Mung bean is my county in addition to wheat, the largest non-staple food varieties, the acquisition of tens of thousands of pounds per year, large inventories, the transfer of heavy task. Mung bean like extremely serious harm, the victimization rate of 30-40%, and some as high as 70%, 10-15% weight loss. Private storage in the altar, cylinder, a small amount of bags of mung beans and cowpea, but also suffer. Over the years, we are all in the high-dose fumigation after the acquisition, and more medication, insecticide is not complete, serious waste of pharmaceuticals and due to fumigation is not timely, the high rate of insect pests, dead bugs density, often relegation downgrade, resulting in economic The loss is not small. Last year, we conducted a trial of intermittent smuggling with aluminum phosphide to prevent and cure mung bean in the dry period, which has a good effect on ensuring the quality of the commodities and improving the economic benefits. Test proved: Mung bean per kilogram with aluminum phosphide tablets
