Abstract
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...
Examples
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 a three-necked bottle, add 30% NHO3 200g, stir and react at 90°C for 2 hours, filter, transfer the precipitate to a 400ml beaker, add 200ml of water, and adjust the pH to 7 with NaOH -8, extracted in a water bath at 100°C for 1 hour, adjusted the pH to 6 with 40% HNO3, separated the bath liquid after settling, dried it by infrared at 70°C to obtain coal-based acid; weighed 5g of the sample and added it to the mixer, and simultaneously Add 100 grams of Bacillus thuringiensis insecticide into the stirring mixer, stir and mix evenly to obtain the product.
