A multipurpose bactericial composition for farm crop

Abstract

The invention provides a multi-purpose sterilizing combination for crops. The constituents has weight percentages that: constituent A is 1-50 percent, constituent B is 5-63 percent, constituent C is 0.1-5 percent, common carrier is 25-88 percent, and common assistant is 5.0-25 percent. The constituent A is any one of difenoconazole, prochloraz, prochloraz manganic salt, or metalaxyl-m. The constituent B is any one of basic copper sulfate, bluestone, copper hydroxide, copperchloride, cuprous oxide, copper acetate, cuaminosulfate, amber glue copper adipic acid, or copper rosinate. The constituent C is any one of diethyl aminoethyl hexanoate, sodium nitrophenolate, naphthyl acetic acid, gibberellins, or brassinosteroids lactone. The invention not only can multiply the expansion of the preventing spectrum on the crop disease, can delay the produce of the drug-resistance; can lower the dosage of each agent in the combination, can obviously improve the medical effect of the constituents when being used separately, can prevent and cure the disease, can facilitate the growth of the crop, and can increase the yield and the harvest of the crop.

Description

technical field [0001] The invention relates to a pesticide, which is a bactericidal composition which is applied to the prevention and control of crop diseases and has a certain yield-increasing effect. Background technique [0002] At present, the fungicides used in crop production are mainly for protection, treatment and eradication. Applying pesticides before the pathogens infect the crops protects the crops from the infection of the pathogens, and applying the pesticides after the pathogens have already infected the crops inhibits the growth of the pathogens or kills them. Germs. When the pathogens have infected the crops or the diseases have generally occurred, the pesticides have caused a certain loss to the crops, and the application of any fungicides will not make the diseased spots disappear, and the crops will recover as before, which will have a certain impact on the yield of the crops. [0003] Furthermore, any fungicides will cause phytotoxicity due to imprope...

AI Technical Summary

Problems solved by technology

When the germs have infected the crops or the disease has generally occurred, the pesticides have been applied, and the crops have caused a certain loss. No application of any fungicide can make the diseased spots disappear, and the crops recover as before, which has caused a certain impact on the yield of the crops.

[0003] Furthermore, any fungicides will cause phytotoxicity due to improper use, especially copper fungicides, when the dew is not dry in the morning, shortly after rain, continuous cloudy or dense fog and other adverse conditions, the water on the leaf surface will dissolve. The amount of copper exceeds the amount of copper that the crops can tolerate, and it is easy to cause phytotoxicity, cause damage to the crops, lead to scorched leaves, fallen flowers and fruits, stunted growth, and even plant death
