Avoid long-term use after preparation
It is best to use the stone sulphur mixture which has been prepared well, otherwise it will reduce the efficacy.
Do not look at the type and stage of fruit trees when applying
Some fruit trees are sensitive to sulfur, and blind use can cause phytotoxicity. For example, peach, plum, pear and other fruit trees should not use stone sulfur mixture. In addition, the fruit tree should not be used after the coloring, otherwise it will cause a lot of fruit drop.
Avoid excessive concentration
The concentration of the stone sulphur mixture in the orchard should be determined according to the climatic conditions and the object of control, otherwise it is easy to cause phytotoxicity. In winter, the temperature is low, the plants are in the dormant stage, and the concentration can be higher; in summer, the temperature is high and the concentration should be lower. Generally, a stone sulphur mixture of 3 degrees - 4 degrees can be used in the dormant period of the fruit tree, and only 0.3 degree - 0.4 degree can be used in the vigorous growth stage.
Avoid mixing at will
Stone sulphur mixture is an alkaline pesticide , which can not be mixed with organophosphorus pesticides and other base pesticides. Otherwise, acid-base neutralization will reduce the efficacy. Some people think that Bordeaux mixture is also an alkaline pesticide and it is mixed with a stone sulfur mixture. But this law is not appropriate. Because the chemical reaction can also occur after the two are mixed, not only the efficacy is lowered, but also the phytotoxicity is easily caused. In addition, it is not advisable to mix the stone sulphur mixture with other copper preparation pesticides.
Avoid long-term use
The long-term use of the stone sulphur agent makes the disease resistant to pests and diseases. The higher the concentration, the faster the resistance formation. Therefore, the stone sulphur mixture should be used interchangeably with other pesticides.
