| Abstract: | The efficacy test of 77% wettable powder of coppersulfate calcium on controlling Citrus canker was conducted. The results showed that this reagent had better control efficiency on Citrus canker. With 400 and 500 times liquid, its control efficiencies to fruits were 79.92% - 85.65% and to leaves were 80.74% - 86.07% before the third spraying. Its control ef- ficiency to fruits were 80.06% -86.59% and to leaves were 81.48% -86.87% after 15 days of the third spraying. The recommended dose to control Citrus canker in its early occurrence were 400 and 500 times liquid, It should be continuously sprayed for more than 2 or 3 times in the interval of 10 days. |
