中文摘要: |
为减少化学农药的施用量, 筛选出高效生物杀线剂, 选用0.3%苦参碱水剂?1.8%阿维菌素乳油?2亿孢子/g淡紫拟青霉粉剂和2.5亿孢子/g厚孢轮枝菌微粒剂4种生物杀线剂进行田间药效试验?结果表明, 0.3%苦参碱AS?1.8%阿维菌素EC?淡紫拟青霉DP和厚孢轮枝菌MG对番茄根结线虫病的防效分别为64.0%?44.0%?44.0%和32.0%, 增产率分别为92.6%, 53.1%, 15.9%和-0.1%?苦参碱对番茄根结线虫病的防效明显高于对照10%噻唑膦GR和其他生物杀线剂, 可以更好地抑制番茄根部根结的形成, 控制土壤中2龄幼虫的数量, 促进植株生长, 适合在生产上推广应用, 促进设施蔬菜的可持续安全高产和稳产? |
英文摘要: |
In order to reduce the amount of chemical pesticides and screen out high-efficient bio-nematicides, the control effect of four bio-nematicides including matrine 0.3% AS, abamectin 1.8% EC, Paecilomyces lilacinus 200 million spores/g DP and Verticillium chlamydosporium 250 million spores/g MG were evaluated on tomato root knot nematodes, and the influences on tomato yield were also investigated. The results demonstrated that matrine 0.3% AS, abamectin 1.8% EC, P.lilacinus DP and V.chlamydosporium MG displayed control efficacies of 64.0%, 44.0%, 44.0% and 32.0% against tomato root-knot nematode and yield increase rate of 92.6%, 53.1%, 15.9% and -0.1%, respectively. The control effect of matrine was significantly higher than fosthiazate 10% GR and the other three bio-nematicides. Matrine showed the best control effect on J2 larvae and the formation of root-knots, and also could promote plant growth.Thus, in order to promote sustainable, safe and high yield development of greenhouse vegetables, matrine was suitable for popularization and application in production. |
