摘　　要：[目的]为了探究乙螨唑、阿维菌素、联苯肼酯桶混氨基酸水溶肥对柑橘全爪螨的减量增效作用,为农药减量增效使用提供理论支撑。[方法]以乙螨唑、阿维菌素、联苯肼酯常量及分别减量25%、减量50%桶混氨基酸水溶肥田间测试其增效作用。[结果]添加氨基酸水溶肥后,乙螨唑速效性增强,药后1 d,乙螨唑减量25%、50%及乙螨唑常量的防效高于单剂常量7.67%~13.82%;添加氨基酸水溶肥后,除了药后1 d,阿维菌素减量50%+氨基酸水溶肥低于阿维菌素单剂常量4.8%外,阿维菌素常量+氨基酸水溶肥、阿维菌素减量25%+氨基酸水溶肥的防效提升4.45%~5.4%,在其他调查时段添加氨基酸水溶肥后,阿维菌素各剂量的防效均高于单剂常量;添加氨基酸水溶肥后,联苯肼酯常量、减量25%、减量50%的防效均高于联苯肼酯单剂常量。[结论]添加氨基酸水溶肥可以减少乙螨唑、阿维菌素、联苯肼酯的使用量,具有减量增效作用。[Aims] This study aims to evaluate the decrement and synergistic effects of etoxazole, abamectin and bifenazate barrel-mixed with amino acid water soluble fertilizer on citrus Panonychus citri and provides theoretical support for pesticides decrement and synergism. [Methods] The decrement and synergistic effects of etoxazole,abamectin and bifenazate barrel-mixed with amino acid water soluble fertilizer additives were tested in the field by constant treatment and reduction treatments. [Results] By adding amino acid water soluble fertilizer, the fast effect of etoxazole were enhanced, and the control effect of etoxazole with constant, 25 and 50% reduction treatment were7.67-13.82% higher than that of etoxazole single dose constant when 1 DAT [day(s) after treatment]. By adding amino acid water soluble fertilizer, the control effect of abamectin with 50% decrement treatment was reduced by 4.8% when1 DAT, however, the control effect of abamectin with constant and 25% decrement treatment increased by 4.45-5.4%in other investigation periods. By adding amino acid water soluble fertilizer, the control effect of bifenazate with constant, 25 and 50%reduction treatment were all higher than that of bifenazate single dose constant. [Conclusions]The decrement and synergism of etoxazole abamectin and bifenazate could be obtained by adding amino acid water soluble fertilizer.
