Experiment on Mixed Pesticides for Controlling Tobacco Brown Spot and Myzus persicae (Sulzer)

In order to study the practical control effect on tobacco brown spot and Myzus persicae (Sulzer),plot and indoor experiments on 5 mixtures of pesticide and bactericide, such as Admire+Carbcndazim+Dimethachlon, Decis+Dali, Meiyaning+Polyoxins, DDVP+Dimethachlon, Dipterex+Dimethachlon and Copper,were conducted with single agents as the contrast. The results showed that two mixtures, Admire at a dilution of 3000 + (Carbcndazim+Dimethachlon) at a dilution of 500 and Decis at a dilution of 2000+Dali at a dilution of 500, had better control effects both on tobacco brown spot and Myzus persicae (Sulzer).
