Abstract

The field experiment was carried out to determine the control effects of different concentrations of 0.3%matrine·berberine·flavone aqueous solution on tomato late blight.The results showed that the control efficiency of 50,100 and 200 times solutions of 0.3% matrine·berberine·flavone were 77.89%,74.11%,73.56% to leaves,and 79.50%,75.75%,73.75% to fruits.The control efficiency of 25% Amister suspension concentrate(SC) and 80% Mancozeb wettable powder(WP) were 80%,61.38% to leaves,and 78.34%,63.25% to fruits.The control efficiency of the tested fungicide was similar to that of 25% Amister SC,but was significantly more effective than that of 80% Mancozeb WP.
