Abstract

The invention discloses a grape downy mildew prevention and treatment medicine. The medicine is prepared by using the following components, by weight, 5 parts of sodium dichloroisocyanurate, 2-8 parts of eugenol, 2-6 parts of myclobutanil, 1-5 parts of kresoxim methyl, 20-30 parts of Fructus Cnidii, 15-25 parts of mulberry leaf, 12-20 parts of Perilla frutescens, 10-20 parts of Artemisia carvifolia, 0.2-0.6 parts of potassium nitrate, 40-60 parts of chitosan, 0.2-0.8 parts of carboxymethylcellulose sodium and 0.03-0.07 parts of Tween 80. Compared with medicines in the prior art, the grape downy mildew prevention and treatment medicine prepared in the invention has the advantages of protruding effect, long persistent period, reduction of the use frequency, raw material saving and environmental pollution reduction.

Description

technical field [0001] The invention relates to a control agent for grape downy mildew, which is applied in the field of agriculture. Background technique [0002] Grape downy mildew is a worldwide grape disease. It is distributed in various grape producing areas in my country, especially in rainy and humid areas. It is one of the main diseases of grapes. Grape downy mildew mainly damages leaves, and can also infect young tissues such as new shoots and young fruits. When the leaves are damaged, the initial light yellow water-soaked small spots with unclear edges gradually expand into brown irregular or polygonal lesions, and several spots connect to become large irregular spots. When the weather is humid, white downy mildew-like substances, which are the cyst peduncles and sporangia of the pathogen, are produced on the back of the lesions. When the disease is severe, the diseased leaves wither early and drop early. The young shoots are damaged, forming water-soaked spots...
