甲拌磷因其毒性高防治应用受到限制。国外仅应用粒剂根施于麦类、豆类、玉米、水稻、高粱、棉花、甜菜、甘蔗、马铃薯、莴苣、番茄、黄瓜等多种作物上。我国甲拌磷乳油也仅限于棉花拌种使用。本试验目的在于利用甲拌磷颗粒剂熏蒸作用防治高粱蚜虫,探索利用颗粒剂熏蒸作用防治高粱蚜虫的新途径。 Phorate because of its high toxicity and control applications are limited. Foreign only applied granule root applied to wheat, beans, corn, rice, sorghum, cotton, sugar beet, sugar cane, potato, lettuce, tomato, cucumber and other crops. China phorate phosphoric acid is also limited to cotton seed dressing use. The purpose of this experiment is the use of phorate particles fumigation control of sorghum aphids, to explore the use of granules fumigation a new approach to the control of sorghum aphids.
