Stone-sulfur mixture can kill diseases, pests and eggs by infiltrating and eroding the body walls of germs and pests. It is a kind of inorganic sulfur preparation which can not only kill bacteria but also kill insects and mites. It can control many kinds of diseases and insect pests, such as powdery mildew, rust, brown rot, brown spot, scab, red spider, scale insect and so on. The use of stone-sulfur mixture has the following points for attention: 1. Avoid random mixing: stone-sulfur mixture is an alkaline pesticide and should not be mixed with organophosphorus pesticides and other taboo alkali pesticides, otherwise, acid-base neutralization will reduce the efficacy. Some people think that Bordeaux liquid is also an alkaline pesticide and mix it with stone-sulfur mixture. But this method is also inappropriate. Because the mixture of the two can also have a chemical reaction, which not only reduces the efficacy, but also easily leads to drug damage. In addition, stone-sulfur mixture should not be mixed with other copper pesticides. 2. Avoid long-term use: long-term use of stone-sulfur mixture to make diseases and insects produce drug resistance, the higher the concentration, the faster the resistance is formed. Therefore, stone-sulfur mixture should be used alternately with other pesticides. 3. Avoid using it for a long time after preparation: the stone-sulfur mixture that has been boiled had better be used up at one time, otherwise it will reduce the efficacy. 4. do not look at the types and growth stages of fruit trees: some fruit trees are more sensitive to sulfur and will cause drug damage if they are used blindly. Such as peach, plum, pear and other fruit trees should not use stone sulfur mixture. In addition, stone sulfur mixture must not be used after fruit tree coloring, otherwise it will cause a large number of fruit drop. 5. Avoid too high concentration: the concentration of stone-sulfur mixture in orchard should be determined according to climatic conditions and control objects, otherwise it is easy to cause drug damage. The winter temperature is low, the plant is in the dormancy stage, the use concentration can be higher; the summer temperature is high, the use concentration should be lower. Generally speaking, the stone-sulfur mixture of 3-4 degrees can be used in the dormant period of fruit trees, but only 0.3-0.4 degrees can be used in the prosperous growth stage.
