Problems solved by technology

For example, the invention patent with the patent application number of 200410018121.5 can overcome the problem of unstable performance and slow onset of Bacillus thuringiensis single use, and achieve the purpose of good insecticidal effect, but the proportion of abamectin in its formula is too high. (>8% or more), because the price of avermectin is relatively expensive, it costs about 1,200 yuan per kilogram at present, the cost is too high, and the economic benefits are not calculated

Abstract

The invention relates to a bio-pesticide which mainly solves the problems of the currently used bacillus thuringiensis (BT) such as unstable performance, narrow insecticidal spectrum and slow effect. The main compositions of the invention are avermectin and BT raw pesticide. The compositions also comprise filler calcium carbonate, detergent (LS), dispersant, white carbon black, sodium lauryl sulfate (K12) and solvent acetone. According to the weight percentage, the compositions comprise 0.2%-0.8% of avermectin, 5%-15% of BT, 2%-8% of detergent (LS), 2.8%-4% of dispersant (NNO), 3.5%-6% of white carbon black, 1%-5% of sodium lauryl sulphate (K12), 1%-3% of solvent acetone and 80%-85% of filler calcium carbonate. The bio-pesticide of the invention is a wettable powder and has the advantages of stable performance, good effect, wide insecticidal spectrum, quick effect, no effects on the environment, which is applicable for harmless and green agricultural products, forest and garden flowers.

Description

1. Technical field: [0001] The invention relates to a biological pesticide, in particular to a wettable powder of Bacillus thuringiensis. 2. Background technology: [0002] At present, with the development of science and technology and human beings attach great importance to green environmental protection, in terms of agricultural production and forest resource pest control, green and environmentally friendly biological pesticides are being researched and developed worldwide to replace chemical pesticides, especially in the prevention and control of forest pests and diseases. There is a lack of effective biopesticides. For example, the invention patent with the patent application number of 200410018121.5 can overcome the problem of unstable performance and slow onset of Bacillus thuringiensis single use, and achieve the purpose of good insecticidal effect, but the proportion of abamectin in its formula is too high. (>8% or more), because the price of avermectin is more e...
