摘要
为给防治烟草普通花叶病的药剂选择提供依据 ,进行了“毒消”6 0 0倍、“病毒必克”5 0 0倍 (药剂 )和氨基酸 30 0倍、“丰农”5 0 0倍 (叶面肥 )田间防效试验。结果表明 ,烟株发病初期开始施药 ,“毒消”6 0 0倍在首次施药后防效达 73.2 4 % ,第 3次施药后各药剂防效下降并在停止施药后 30d病情发生反弹 ;烟株发病中期开始施药 ,首次施药后“病毒必克”5 0 0倍防效达 75 .90 % ,此后各药剂防效均下降 ;氨基酸30 0倍和“丰农”5 0
For selecting more effective chemicals to control TMV, the field control effect experiments of Duxiao at a dilution of 600, Ribaririn at a dilution of 500, amino acid at a dilution of 300, and photosynthesis bacterium at a dilution of 500 (foliar fertilizer) were conducted. The results showed that the control effects of Duxiao at a dilution of 600 was 73.24% in the initial stage of TMV, and that of Ribaririn at a dilution of 500 was 75.90% while started application in the metaphase of TMV, the effects of all these chemicals were decreased thereafter. The control (effects) of amino acid and photosynthesis bacterium were worse.
