example 1

[0043] Example 1. Preparation of liquid compound bactericide (water emulsion)

[0044] The first step is the preparation of 10% propane amidine metalaxyl bactericidal composition (water emulsion)

[0045] Propanamidine 2.0%, Metalaxyl 8%, Methanol 45%, 5% DMF, Stabilizer Castor Oil 8%, Penetrating Agent Azone 0.1%, Antifreeze Ethylene Glycol 5%, Surfactant OP-1010 %, 16.9% of distilled water, stir evenly to obtain a sterile water emulsion.

[0046] In the second step, take 0.3-0.5% of 10% propane amidine metalaxyl sterilizing water emulsion, slowly add 99.5-99.7% of the prepared biogas slurry, and put it into a homogenizer for vigorous mixing and homogenization.

example 2

[0047] Example 2. Preparation of biogas slurry compound fungicide (emulsifiable concentrate)

[0048] The first step is the preparation of 10% propane amidine metalaxyl bactericidal composition (emulsifiable concentrate)

[0049] Propanamidine 2%, Metalaxyl 8%, Surfactant Agromilk 500 10%, 1601 5%, Solvent methanol 45%, DMF 10%, Ethyl acetate 9.5%, Stabilizer castor oil 10%, penetrant 0.5% lauryl azepine, put each component in a brewing kettle and mix thoroughly.

[0050] In the second step, 0.3-0.5% of 10% propane amidine metalaxyl sterilizing emulsifiable concentrate is slowly added to 99.5-99.7% of the prepared biogas slurry, and then put into a homogenizer for vigorous mixing and homogenization.

example 3

[0051] Example 3. Evaluation of the efficacy of the biogas slurry compound fungicide of the present invention on indoor potted cucumber downy mildew

[0052] Collect fresh cucumber downy mildew diseased leaves, dipped in sterile water to wash down the downy mildew on the back of the diseased leaves, prepare a sporangia suspension, inoculate at a concentration of 10×10 under a microscope, 80-100 spores / field of view, select At the stage of 4 to 5 true leaves (remove the growing points), potted cucumber seedlings with consistent growth are sprayed to inoculate cucumber seedlings, 10 mL / pot, and spray evenly on the surface of cucumber leaves. Then place the inoculated potted cucumber seedlings in a dark condition with a temperature of 23-25°C and RH>95% for 24 hours, and then spray the cucumber seedlings with different concentrations of medicament. Drip water shall prevail, 5 replicates (5 pots of seedlings) for each concentration, with clear water as the control, and dry naturally ...

Abstract

The invention relates to a biogas liquid composite disinfectant liquid and a preparation method thereof. The biogas liquid composite disinfectant liquid belongs to the field of pesticide, and comprises a bactericidal composition and prepared biogas liquid which are compounded by a certain weight percent, wherein the bactericidal composition comprises the following ingredients by weight percent: 0.1-2% of propamidine, 5-10% of metalaxyl, and 94.9-88% of solvent and pesticide adjuvant. The bactericidal composition can be prepared into missible oil, aqueous emulsion or soluble liquor. The prepared bactericidal composition and the biogas liquid are uniformly mixed by the weight percent of 99.5-99.7% of the biogas liquid and 0.3-0.5% of the bactericidal composition. The disinfectant liquid provided by the invention has remarkable bactericidal effect on downy mildew and gray mold, has remarkably improved bactericidal activity in comparison with single dose and the bactericidal composition, has prolonged lasting period, can play a role in treating various diseases with one medicine, obviously reduces the poisonousness of the pesticide, is safe to use, has various preparation formulations, can be prepared simply, and has extremely high popularization value.

Description

[0001] Inventor: Guo Shenghu, Zhang Yuanpei, Zheng Guobao, Kong Dejie, Zhu Jinxia, ​​Wang Ming, Chen Xiaojun [0002] Applicant: Ningxia Academy of Agriculture and Forestry Sciences Technical field [0003] The invention belongs to the technical field of agricultural sterilization preparations, and specifically relates to the processing and application of a biogas slurry composite sterilization liquid. Background technique [0004] With the development of science and technology, chemical pesticides have played an active role in promoting high-yield, high-quality, and high-efficiency agricultural cultivation. However, the excessive application of pesticides and the unreasonable development of agricultural natural resources have led to serious pollution of the atmosphere, water quality, and soil. Health has brought great harm. In recent years, the rapid development of the livestock and poultry breeding industry has made the pollution of livestock and poultry manure sewage increasingl...
