For other tree species, different formulas and ratios should be selected according to their characteristics. For apples that are sensitive to copper and resistant to lime, they can be used in lime or multi-type ratio; pears that are less sensitive to lime and copper can be used in the same amount of lime; sensitive to lime and resistant to copper. The grapes can be matched with a half-size of lime. When mixing with organic phosphorus, it should be used with caution. After spraying the stone sulfur mixture for 10 days, it can spray the Bordeaux mixture. After spraying the Bordeaux mixture, it takes 20-30 days to spray the stone sulfur mixture. 1 Avoid application on wet days or before the fog is dry to prevent phytotoxicity. Because of the strong permeability of copper sulfate, lime is drenched by rain or dew, and copper ions are left. The copper ions are very corrosive and easily cause damage to leaves and young fruits. Spray in the summer to avoid the hot sun at noon, so as not to cause high temperature damage caused by lime. Spray in the rainy season, increase the amount of lime as appropriate. 2 can not be mixed with alkaline agents, Bordeaux mixture with stone sulphur mixture, bacteriostatic, thiram, Fumei arsenic, etc., or alternate use interval is too short, are easy to produce phytotoxicity. 3 Bordeaux mixture should not be formulated in metal containers. 4 Bordeaux mixture is toxic to silkworms and should not be used on mulberry trees. 5 with the use.
