Problems solved by technology

However, there are also unsatisfactory shortcomings in the Bacillus thuringiensis biopesticides, and there are two main shortcomings: (1) rapid decay under natural conditions, poor control effect in the field, and short duration of effect; (2) slow poisoning and killing effects (Yang Chunhe, Mu Canxian, Pesticide Translation Collection, 1997, 19(1), 1-7)

Embodiment 1

[0012] Add 100 grams of Bacillus thuringiensis insecticide and 10 grams of commercially available fulvic acid (purity ≥ 90%) into a stirring mixer, stir and mix evenly to obtain coal-based acid—Bacillus thuringiensis insecticide.

Embodiment 2

[0014] Add 100 grams of Bacillus thuringiensis insecticide and 30 grams of commercially available brown humic acid (purity ≥ 60%) into a stirring mixer, stir and mix evenly to obtain the product.

Embodiment 3

[0016] Take 50 grams of weathered coal with humic acid content ≥ 60% in the three-necked bottle, add 30% HNO 3 200g was stirred and reacted at 90°C for 2 hours, filtered, transferred the precipitate to a 400ml beaker, added 200ml of water, adjusted the pH to 7-8 with NaOH, extracted in a water bath at 100°C for 1 hour, and then used 40% HNO 3 Adjust the pH to 6, separate the bath liquid after settling, and dry it by infrared at 70°C to obtain coal-based acid; weigh 5g of the sample and add it to the mixer, and add 100 grams of Bacillus thuringiensis insecticide into the stirring mixer and stir to mix Get the product evenly.

Abstract

The present invention relates to a coal base acid bacillus thuringiensis pesticide. It is made up by using coal base acid and bacillus thuringiensis pesticide according to the weight ratio of 0.05-2.0:1 and uniformly mixing and stirring them by means of stirring mixer. Said invention can greatly raise its insecticidal effect, can promote growth and development of crops, can raise adverse resistance of crops and their disease-preventing and disease-resisting capability, and can improve quality of crops, etc.

Description

Technical field: [0001] The invention relates to a pesticide, in particular to a pesticide composed of coal-based acid and bacillus thuringiensis. Background technique: [0002] The long-term application of chemical pesticides not only increases the dosage due to the enhancement of drug resistance, but also causes more serious harm to the environment due to excessive application. Excessive application of chemical pesticides also seriously pollutes the quality of crops and directly damages human health. The emergence and development of biopesticides show bright prospects for solving this problem. Among them, the Bacillus thuringiensis preparation is currently the most widely used bacterial pesticide preparation, which can effectively control more than 150 kinds of Lepidoptera pests, and its consumption accounts for about 90% of the current various biological pesticides. The sale of this pesticide has reached 150 million U.S. dollars abroad in 1994 (Mao Shuilian, World Agricu...
