6%增效阿罗蒎兹微乳剂防治黄瓜根结线虫

Effect of Alopaizi 6% ME on Cucumber Root Knot Nematode

用6%增效阿罗蒎兹微乳剂(有效成分:苦豆子水提取物、阿维菌素)处理温室土壤防治黄瓜根结线虫试验表明:阿罗蒎兹微乳剂可较好地控制黄瓜根结线虫危害。阿罗蒎兹微乳剂7.5、15.0、22.5L/hm2三个处理,药后90d土壤中2龄幼虫减退率分别为-12.23%、31.50%、43.52%,而对照药剂1.8%阿维菌素15L/hm2处理的线虫减退率为-37.65%。药后90d6%增效阿罗蒎兹微乳剂及各处理防治效果分别为54.52%、70.16%、74.84%,而对照药剂为50.81%。阿罗蒎兹微乳剂可有效地控制黄瓜根结线虫的危害,有较高的推广应用价值。

The trial experiment showed that Alopaizi 6% ME（the mixture extract of Sophora alopecuraides and avermectin） was an excellent nematicide for controlling cucumber root knot nematode. The decline rate of J2 was -12.23, 31.50 and 43.52% by Alopaizi 6% ME applied at 7.5, 15.0, 22.5 L/ha, respectively while avermectin was -37.65% after 90 days. The control effect was 54.52, 70.16 and 74.84% by Alopaizi 6% ME applied at 7.5, 15.0, 22.5 L/ha, respectively while Avermectin was 50.81% after 90 days. These results indicated that Alopaizi 6% ME could be a prospective nematocide for cucumber root-knot nematodes control.
