Oxazolyl quinoline organic copper compound, preparation method of the oxazolyl quinoline organic copper compound, oxazolyl quinoline organic copper compound agent, and use of the oxazolyl quinoline organic copper compound in prevention and treatment of crop diseases

Abstract

The invention discloses an oxazolyl quinoline organic copper compound, a preparation method of the oxazolyl quinoline organic copper compound, an oxazolyl quinoline organic copper compound agent and a use of the oxazolyl quinoline organic copper compound in prevention and treatment of crop diseases. The preparation method provided by the invention comprises the following steps that based on an aqueous phase method, hydroxylamine hydrochloride and ethyl acetoacetate undergo a reaction to produce 3-hydroxy-5-methylisoxazole; the 3-hydroxy-5-methylisoxazole, 8-hydroxyquinoline and a divalent copper salt are added into an organic solvent and undergo a reaction for 1 to 3 hours; and the reaction products are subjected to separation, washing and drying to obtain the oxazolyl quinoline organic copper compound which is a novel oxazolyl quinoline of copper-3-hydroxy-5-methylisoxazole-8-hydroxyquinoline. The preparation method provided by the invention is simple, can be realized easily, has a low cost and does not produce environmental pollution. The novel oxazolyl quinoline of copper-3-hydroxy-5-methylisoxazole-8-hydroxyquinoline has stable properties and a wide sterilization spectrum, can be widely utilized for preventing and treating diseases of tomato late blight, cucumber downy mildew, lychnee downy mildew and apple ring rot disease, has effects of preventing and treating diseases caused by fusarium sp., aphanomyces invadans, pythium aphanidermatum and corticiaceae, and has special effects of treating various soil-borne diseases and seedling blight.

Description

technical field [0001] The invention belongs to the technical field of pesticide chemical industry, and in particular relates to an oxazoquinoline organic copper compound, a preparation method, a preparation and an application in preventing and treating agricultural plant diseases. Background technique [0002] The molecular formula of 3-hydroxy-5-methylisoxazole (hymexazole) is C 4 h 5 NO 2 , the molecular weight is 99, soluble in most organic solvents, stable in acid and alkali solutions, non-corrosive, is a systemic fungicide and plant growth regulator, has systemic and conductivity, can be directly absorbed by Absorbed by the roots of the plant, enter the plant body, and move extremely quickly. It moves to the stem within 3 hours after moving in the root system, and moves to the whole body of the plant within 24 hours. Its metabolites in the plant are two kinds of glucosides, which can promote the growth of plants. The role of growth and root development. In addition...

Problems solved by technology

It is characterized by an advantageous protective fungicide with low cost, but its disadvantages are: first, it is easy to cause phytotoxicity, and its use is prohibited or restricted during the flowering and young fruit stages; second, its miscibility is poor, and most of the inorganic copper preparations are Alkaline pesticides cannot be mixed with most pesticides, which is inconvenient to use; third, it is easy to cause the proliferation of mites and rust ticks, which increases the cost of control in disguise; fourth, the treatment effect is not strong, and it is not easy to use on rice. use

[0008] Although copper fungicides have many advantages, excessive copper ions can easily cause phytotoxicity to crops
