Embodiment 1

[0038] Test drug: 36% parent drug of Alternaria tennatus activating protein, 10% parent drug of Zhongshengmycin.

[0039] experiment method:

[0040] The leaves with typical corn bacterial wilt were selected in Yuanshi County, Shijiazhuang, Hebei Province, and the shape, size and color of the disease spots were observed and measured. In the laboratory, the collected diseased leaves are collected by tissue separation method to isolate the pathogenic bacteria, and then the colonies after purification are selected, and the hyphae of the pathogenic bacteria are picked to observe the morphological characteristics of the conidiophores and conidia.

[0041] The virulence of corn bacterial wilt was determined by mycelial growth rate method. Prepare the two medicaments to be tested to the required concentration with sterile water, draw 1 mL into 9 mL PDA medium (cooled to about 50°C), shake well and pour into a petri dish (φ=90mm) to prepare The drug-containing plates with different ...

Embodiment 2

[0053] Example 2. 30% Alternaria tennatus activating protein Zhongshengmycin aqueous solution (0.5:1)

[0054] Alternaria tennatus activating protein 10%, Zhongshengmycin 20%, Bacillus orientalis 8% (2 billion spores / g), alkyl polyglycoside 6%, ethylene glycol 4%, deionized water to make up to 100% .

Embodiment 3

[0055] Example 3. 30% Alternaria tennatus activating protein Zhongshengmycin aqueous solution (1:1)

[0056] Activating protein of Alternaria tennatus 15%, Zhongshengmycin 15%, Bacillus orientalis 8% (2 billion spores / g), polyacrylate 4%, isopropylene glycol 1.5%, rapeseed oil 11%, deionized water Top up to 100%.

Abstract

The invention discloses a bactericidal composition containing alternaria tenuissima activator protein and zhongshengmycin and application of the bactericidal composition, and relates to the field of agricultural chemicals. The bactericidal composition comprises two active components: alternaria tenuissima activator protein and zhongshengmycin, wherein the weight ratio of the alternaria tenuissima activator protein to the zhongshengmycin is (0.5-3.5): 1. Test results show that the bactericidal composition provided by the invention has obvious synergism, the application amount is reduced, and the use cost is reduced. According to the bactericidal composition, bactericides with different action mechanisms and action modes can be compounded, the application amount of each single agent is effectively reduced, and the bactericidal composition has very good effects in the aspects of enlarging a bactericidal spectrum, delaying the drug resistance of bacteria and fungi, improving the prevention and treatment effect and the like.

Description

technical field [0001] The present invention relates to the field of agricultural chemicals, in particular to a bactericidal composition with improved properties, in particular to a bactericidal composition containing Alternaria ultrafines activating protein and Zhongshengmycin and its antibacterial effect on preventing and treating cereals, vegetables, Application in bacterial or fungal diseases of fruit trees. Background technique [0002] Pesticides refer to chemical agents used in agriculture to prevent and control diseases and insect pests and regulate plant growth. They are widely used in agricultural, forestry and animal husbandry production, environmental and household sanitation, pest control and epidemic prevention, industrial products against mildew and moth, etc. Pesticides can be divided into minerals according to the source of raw materials. Source pesticides (inorganic pesticides), biological source pesticides (natural organic matter, microorganisms, antibioti...
