摘要
１９８３—１９９１年用杀虫剂甲基异柳磷对花生根结线虫病的防效进行了研究，结果表明，于花生播种时，按每公顷用４０％甲基异柳磷乳油有效成分４．５ｋｇ，兑土或水稀释后，施于播种沟内，防效为４６．１％，增产７５％，并有兼治种苗期蚜虫等多种害虫作用。适合于花生根结线虫病发生较轻而虫害发生严重的地区或田块施用。
During the period of 1983-1991,studies on control of peanut root-knot nematode disease with isofenphos-methy1,a kind of insecticide,were conducted. Results indicated that the control effect of applying isofenphos-methy1 4.5kga.i/ha mixed with soil or water to seed furrow with seeding on Meloidogyne hapla was 46.1%,and the yield increased by 75%,compared with the check.This kind of insecticide also showed an obvious effect of controlling aphis and some other pets damaging Peanut seedlings.Using isofenphos-methy1 in those peanut fields with relatively low nematode population level and severe damase of pests,a multiple effect can be obtained.
