Problems solved by technology

Some inducers are sugar substances, which are prone to hydrolysis after being dissolved in water, reducing the active ingredients
At the same time, because the surface of vegetables generally has a waxy layer or superficial fluff, the inducer is not easily absorbed by the plant after spraying, and it is difficult to achieve the inducement and resistance effect.

specific Embodiment approach 1

[0010] Embodiment 1: The composition and mass percentage of this embodiment are: polyglutamic acid 40%, chitosan oligosaccharide 60%.

[0011] The preparation method is: uniformly mixing polyglutamic acid and chitosan oligosaccharide in proportion.

[0012] This specific embodiment adopts polyglutamic acid and chitosan oligosaccharide, mixes evenly according to the ratio, every 667m 2 , 15,000-20,000 times the water, sprayed on the plant surface before the disease occurs, for the prevention and treatment of cucumber downy mildew, tomato gray mold and other fungal diseases.

[0013] This specific embodiment adopts a reasonable ratio of two kinds of biological substances, which are not easy to be hydrolyzed after use, and are more easily absorbed by plants after spraying on vegetables, so as to quickly induce plant resistance, and finally achieve the effect of strong plant growth and disease resistance.

specific Embodiment approach 2

[0014] Embodiment 2: This embodiment differs from Embodiment 1 in that its composition and mass percentage are: polyglutamic acid 35%, chitosan oligosaccharide 65%, and its preparation method is the same as Embodiment 1.

specific Embodiment approach 3

[0015] Embodiment 3: This embodiment differs from Embodiment 1 in that its composition and mass percentage are: polyglutamic acid 65%, chitosan oligosaccharide 35%, and its preparation method is the same as Embodiment 1.

Abstract

The invention discloses a vegetable disease prevention and control preparation containing a plant inducer. The vegetable disease prevention and control preparation contains the components by weight percent of 30-70% of polyglutamic acid and 30-70% of chitooligo saccharide. The preparation method comprises the step of: evenly mixing the polyglutamic acid with the chitooligo saccharide according to a ratio. The polyglutamic acid and the chitooligo saccharide are mixed according to the ratio, namely 1.5-2g of the mixture of the polyglutamic acid and the chitooligo saccharide is mixed with water with the weight being 15000-20000 times that of the mixture of the polyglutamic acid and the chitooligo saccharide in each 667m<2>; and the vegetable disease prevention and control preparation is sprayed at the surfaces of plants for preventing and controlling fungal diseases such as cucumber downy mildews and botrytis cinereas before a disease appears.

Description

Technical field: [0001] The invention relates to the technical field of vegetable disease prevention and control, in particular to a vegetable disease prevention and control preparation containing plant inducers. Background technique: [0002] Vegetables, especially those cultivated in facilities, are susceptible to infection by fungi, bacteria, viruses and other pathogenic microorganisms during the growth process, or due to the stress of unfavorable environments, pathological or physiological diseases, such as cucumber powdery mildew, Chinese cabbage soft rot, Tomato yellow leaf curl disease, lettuce freeze damage, etc. To control vegetable diseases, agricultural control, physical control, biological control, and chemical control measures are generally used alone or in combination. These measures have their own advantages and disadvantages, and in practice, they need to be used in a reasonable manner according to local conditions. [0003] To prevent and control vegetable...
