Embodiment 1

[0016] Example 1: 10% epoxiconazole·5 billion CFU / gram Bacillus subtilis wettable powder

[0017] Formula: according to the weight ratio of econazole and Bacillus subtilis is 20:1, weigh econazole 10%, Bacillus subtilis 0.5%, sodium lauryl sulfate 3.5% (wetting agent), lignin Sodium sulfonate 3.5% (dispersant), kaolin (filler) make up to 100%. The above-mentioned components are coarsely pulverized according to the ratio of the formula, put into a mixer and mixed evenly, and then jet pulverized to obtain 10% epoxiconazole·5 billion CFU / gram Bacillus subtilis wettable powder.

Embodiment 2

[0018] Embodiment 2: 20% epoxiconazole·2 billion CFU / gram Bacillus subtilis wettable powder

[0019] Formula: According to the weight ratio of econazole and Bacillus subtilis as 100:1, take econazole 20%, Bacillus subtilis 0.2%, sodium lauryl sulfate 3.5% (wetting agent), lignin Sodium sulfonate 5% (dispersant), white carbon black 15% (filler), kaolin (filler) make up to 100%. The above-mentioned components are coarsely pulverized according to the ratio of the formula, put into a mixer and mixed uniformly, and then jet pulverized to obtain 20% epoxiconazole·2 billion CFU / gram Bacillus subtilis wettable powder.

Embodiment 3

[0020] Example 3: 25% epoxiconazole · 10 billion CFU / gram Bacillus subtilis wettable powder

[0021] Formula: According to the weight ratio of econazole and Bacillus subtilis is 25:1, take by weight 25% econazole, Bacillus subtilis 1.0%, lignosulfonate 4.5% (dispersant), lauryl Calcium benzenesulfonate 2.5% (wetting agent), white carbon black 8% (filler), kaolin (filler) to make up to 100%. After the above-mentioned components are roughly pulverized according to the ratio of the formula, they are put into a mixer and mixed evenly, and then jet pulverized to obtain a 31.5% epoxiconazole · Bacillus subtilis wettable powder.

Abstract

The invention relates to a bactericidal composition comprising epoxiconazole and bacillus subtilis. Active ingredients are epoxiconazole and bacillus subtilis. If bacillus subtilis technical materialwith a content of 1 trillion spores per gram is 100%, a weight ratio of epoxiconazole to bacillus subtilis is (5-100):1. The composition has a significant synergistic effect, can effectively control rice sheath blight diseases, slows down disease resistance development, and facilitates prolonging a life cycle of epoxiconazole.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a bactericidal composition containing epoxiconazole and Bacillus subtilis. Background technique [0002] Epoxiconazole, English common name: epoxiconazole, is a triazole fungicide. It works by inhibiting the biosynthesis of sterols. This product can effectively control wheat rust, rice false smut and sheath blight, banana leaf spot, apple brown spot. [0003] Bacillus subtilis, English name: bacillus subtilis, is a microbial fungicide, through the antibacterial substance produced by the active ingredient Bacillus subtilis and the mode of site competition and induction of resistance, it can kill and control pathogenic bacteria, so as to achieve the goal of disease prevention and treatment Purpose. [0004] Sheath blight is the main disease of rice. Frequent application of a single agent will lead to increased disease resistance, increased dosage, and shortened agent life cy...
