Problems solved by technology

In some places where the disease occurs seriously, common fungicides such as chlorothalonil, thiophanate-methyl, thiram, etc. alone have no effect
Due to the large-scale application of triadimefon, etc., it has also caused serious resistance and is prone to phytotoxicity.
At present, no one has reported the compounding and application of cyprodinil and tebuconazole

Abstract

The invention provides a bactericidal composition containing cyprodinil, and the active components comprise cyprodinil and propiconazole, the weight percentage of the cyprodinil and the tebuconazole is 1:10 to 10:1, and the optical weight percentage of the active components is 1 to 5:1 through filtration by test formula. The bactericidal composition has obvious synergized function after compounding, is used for preventing and curing altemaria mali roberts, banana leaf spot, banana scab, pear scab, grape botrytis cinerea, and especially has remarkable preventing and curing effect to the grape botrytis cinerea, the banana scab and the pear scab.

Description

Technical field: [0001] The invention relates to the technical field of pesticides, in particular to a fungicidal composition containing cyprodinil and tebuconazole, which is used for the prevention and treatment of fruit tree diseases. Background technique: [0002] Cyprodinil belongs to the class of pyrimidine amine protective fungicides and inhibitors of methionine biosynthesis. No cross-resistance with triazoles, imidazoles, morpholines, phenylpyrroles, etc. The inhibited biosynthetic pathway does not exist in higher animals, and the drug works after spore germination, inhibiting the secretion of fungal hydrolase and the biosynthesis of methionine. It is mainly used to control fungal diseases such as gray mold, powdery mildew, scab, net spot, glume blight, and wheat eye spot. [0003] Tebuconazole, a triazole fungicide, is a systemic fungicide with protective and therapeutic effects. It is an episterol biosynthesis inhibitor, which can be quickly absorbed by the growin...
