23%乙螨唑·三唑锡悬浮剂对柑橘红蜘蛛的田间药效研究

Field Efficacy of 23% Etoxazole and Azocyclotin Suspension Concentrate on Panonychus Citri

乙螨唑为噁唑类新型专用杀螨剂,三唑锡为触杀作用较强的广谱性杀螨剂,由二者制成的复配悬浮剂可起到增效作用。开展了对23%乙螨唑·三唑锡悬浮剂防治柑橘红蜘蛛的田间药效试验。结果表明,有效成分浓度为200、100、50 mg/kg的23%乙螨唑·三唑锡悬浮剂,防治柑橘红蜘蛛速效性好,持效期长;药后1、3、10、15、20、30 d的防效均达到95%以上,与对照药剂20%三唑锡悬浮剂100 mg/kg和110 g/L乙螨唑悬浮剂比较,各处理与三唑锡对照防效相当,极显著优于乙螨唑对照。

Etoxazole is a oxazole special acaricide, azocyclotin is a broad spectrum acaricide with strong contact toxicity, by compound of the two composition,the obtained composite suspension concentrate has the synergistic effect.The field efficacy trials of 23% etoxazole and azocyclotin suspension concentrate on panonychus citri were achieved. The results showed that the acaricide had both excellent fast-acting property and long-last period persistence when the concentration were 200,100,50 mg/kg respectively,the control effect were all above 95% after 1,3,10,15,20,30 days;compared with the check sample ,100 mg/kg 20% azocyclotin suspension concentrate and 110 g/L etoxazole suspension concentrate,the control effects were equivalent to azacyclotin,and he control effects were better than that of etoxazole.
