Abstract

The invention discloses a biological watermelon seed coating formulation and a preparation method and applications thereof. The biological watermelon seed coating formulation can effectively prevent various soil-borne diseases of watermelon and has the growth-promoting effect on the watermelon, increases the watermelon output remarkably, and meanwhile is free of environment pollution and is low in toxicity and safe. The biological watermelon seed coating formulation is simple in production process, low in production cost, convenient to implement and long in storage period, and is applicable to large-scale industrial production and seed treatment.

Description

technical field [0001] The invention relates to a biological pesticide preparation, in particular to a watermelon biological seed coating agent and its preparation and application. Background technique [0002] Watermelon is an annual vine herb. The flesh is crisp and tender, sweet and juicy. In addition to being free of fat and cholesterol, watermelon contains a lot of substances such as glucose, malic acid, fructose, protein amino acid, tomato element and rich vitamin C. Auxiliary curative effect. In addition, the oil content of its seeds reaches 50%, which can be pressed for oil, fried or used as ingredients for cakes. There are more than 10 kinds of watermelon diseases, among which the more serious ones are watermelon blight, watermelon wilt, watermelon anthracnose, watermelon virus disease, watermelon powdery mildew, watermelon leaf blight, watermelon blight, watermelon root-knot nematode, etc. The harm of the disease not only affects the yield of watermelon, but al...
