Embodiment approach 1

[0014] Add 0.5% chitosan aqueous solution to solid components such as starch and granulate to make water-dispersible granules, and then mix it with 100 million spores / gram of Bacillus subtilis microcapsules. The mixed preparation contains chitin per kilogram Polysaccharide 5 grams, Bacillus subtilis 100 billion.

Embodiment approach 2

[0015] Embodiment 2 The effect of biological combination preparations on the prevention and treatment of plant virus diseases

[0016] The biological combination preparation prepared in Embodiment 1 is used for preventing and treating capsicum virus disease. The capsicum that has already had viral disease was selected for the test, and the biological combination preparation was divided into three concentrations and diluted as treatments, with 50 plants for each treatment, and repeated 4 times. A total of 5 treatments were set up in the experiment: treatment 1: the biological combination preparation was diluted 100 times the medicinal solution; treatment 2: the biological combination preparation was diluted 300 times the medicinal solution; treatment 3: the biological combination preparation was diluted 500 times the medicinal solution; treatment 4: virus killer; Treatment 5: clean water control. Spray once every 5 days, and investigate the incidence rate after using it three ...

Abstract

The invention relates to a biological combination preparation for preventing and controlling plant diseases and insect pests. The biological combination preparation is prepared by mixing active polysaccharide and bacillus subtilis according to the ratio that 100,000,000 to 10,000,000,000 bacillus subtilis per gram is added into 0.5 to 10 percent active polysaccharide; and the function of the combination preparation comprises but not limited to the biological combination preparation for preventing and controlling plant diseases and insect pests, which is used for adjusting the growth and development of plants and preventing and controlling plant diseases and insect pests. Positive significance in reducing dependence on chemical pesticide by agricultural production is achieved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a biological combination preparation for preventing and controlling plant diseases and insect pests and promoting plant growth. Background technique [0002] With the requirements of economic development and sustainable environmental development, many countries have introduced policy measures to reduce the use of chemical pesticides and fertilizers. Finding new agricultural disease control measures that conform to the sustainable development of agriculture has become a hot spot in current agricultural production research. Due to the advantages of no pollution and no residue, biological pesticide products have attracted people's attention. With the development of the chemical industry and the expansion of the use of pesticides and fertilizers, the number and variety of chemical pesticides are increasing. Now the world's total output of chemical pesticides (in terms of active ingredient...
