Embodiment 1

[0013] 10 grams of amino oligosaccharidone (100% weight), 100 grams of Bacillus subtilis with 200 billion live spores per gram, 30 grams of sodium lauryl sulfate, 40 grams of diffusing agent NNO, 50 grams of white carbon black, and the balance of kaolin, Add to 1000 grams, and the mixture is jet-milled to obtain a wettable powder with 1% amino-oligosaccharin content and 20 billion / gram Bacillus subtilis content.

Embodiment 2

[0015] Amino oligosaccharin (100% weight) 20 grams, 200 billion live spores / gram Bacillus subtilis 20 grams, sodium lauryl sulfate 70 grams, diffusing agent NNO 90 grams, white carbon black 120 grams, kaolin remainder, add to 1000 grams, the mixture is jet milled to obtain a wettable powder with an amino-oligosaccharin content of 2% and a Bacillus subtilis content of 4 billion / gram.

Embodiment 3

[0017] Add 5 grams of amino oligosaccharin (100% weight), 200 grams of Bacillus subtilis with 200 billion live spores per gram, directly add deionized water to make up to 1000 grams, filter and stir evenly with a high-speed homogenizer to obtain amino Aqueous formulation with oligosaccharin content of 0.5% and Bacillus subtilis content of 40 billion / g.

Abstract

The invention relates to a biological bactericide composition and an application thereof to a wilt. The biological bactericide composition comprises active components including amino-oligosaccharin and bacillus subtilis, wherein the weight content of the amino-oligosaccharin is 0.5-5%; the content of the bacillus subtilis is 1.0-1,000.0 hundred million active spores per gram. The biological bactericide composition disclosed by the invention is testified by a field trial and has good prevention and treatment effects on watermelon and melon wilts; meanwhile, all the active components are compounded to further improve the prevention effect and the prevention effect is obviously better than that of a single-dosage variety.

Description

technical field [0001] The invention relates to a biological fungicide composition and its application on fusarium wilt. Background technique [0002] Bacillus subtilis is a mesophilic, aerobic, spore-forming, rod-shaped bacterium with diverse physiological characteristics, wide distribution, and easy isolation and culture. The bacterium exists widely in nature, is non-toxic and harmless to humans and animals, does not pollute the environment, can produce a variety of antibiotics and enzymes, has broad-spectrum antibacterial activity and strong resistance to stress. Bacillus subtilis can not only widely exist in the external environment such as soil and plant rhizosphere surface, but also is a common endophytic bacteria in plants, especially in the roots and stems of plants. At present, the fungus has shown good disease control effect on rice, cotton, pepper, tomato flowers and other crops. Because Bacillus subtilis has outstanding characteristics such as fast growth, simp...
