Problems solved by technology

Although powdery mildew can be controlled chemically, it is difficult for conventional chemical agents to achieve the ideal control effect due to the large number of physiological races that harm melon powdery mildew
[0003] Several mainstream fungicides currently on the market for the treatment and prevention of melon powdery mildew have been continuously used by farmers in recent years, and the resistance of the bacteria has increased.

Embodiment 1

[0057] A powdery mildew prevention and control synergist, comprising 4% tetraflurazole aqueous emulsion (trade name Domeco, produced by Italy Eseg Company) and potassium phosphite solution containing amino acid.

[0058] Dilute the 4% tetrafluconazole aqueous emulsion in the powdery mildew control synergist to 1000 times, and dilute the amino acid-containing potassium phosphite solution to 660 times before applying. The content of each component in the potassium phosphite solution containing amino acid is as follows:

[0059] P 2 o 5 30%, K 2 O 15%, free amino acid 18%, FeO 0.4%, MnO 0.5%, humic acid 2% and water 34.1%.

Embodiment 2

[0061] A powdery mildew prevention and control synergist, comprising 25% pyrimethrimol suspension concentrate (trade name Heyi pyrithrimol, produced by Jiangxi Heyi Chemical Co., Ltd.) and amino acid-containing potassium phosphite solution.

[0062] Dilute the 25% pyrimethrimol suspension concentrate in the powdery mildew control synergistic agent to 750 times, and dilute the amino acid-containing potassium phosphite solution to 660 times before applying. The content of each component in the potassium phosphite solution containing amino acid is as follows:

[0063] P 2 o 5 30%, K 2 O 15%, free amino acid 18%, FeO 0.4%, MnO 0.5%, humic acid 2% and water 34.1%.

Embodiment 3

[0065] A powdery mildew prevention and control synergist comprises 80% sulfur water dispersible granules (trade name Sturning, produced by German Sturning Company) and potassium phosphite solution containing amino acid.

[0066] Dilute the 80% sulfur water dispersible granule in the powdery mildew control synergistic agent to 500 times, and dilute the potassium phosphite solution containing amino acid to 660 times before applying. The content of each component in the potassium phosphite solution containing amino acid is as follows:

[0067] P 2 o 5 30%, K 2 O 15%, free amino acid 18%, FeO 0.4%, MnO 0.5%, humic acid 2% and water 34.1%.

Abstract

The invention provides a synergistic agent for preventing and treating powdery mildew, a synergistic method for preventing and treating powdery mildew by using the synergistic agent and an applicationof the synergistic agent, and relates to the technical field of agriculture. The synergistic agent provided by the invention comprises a powdery mildew prevention and treatment agent and an amino acid-containing potassium phosphite solution, and the powdery mildew prevention and treatment agent and the amino acid-containing potassium phosphite solution are matched with each other, so that the prevention effect on powdery mildew can be further improved, and the lasting period is prolonged, wherein the potassium phosphite solution containing amino acid comprises the following components in specific content: P2O5, K2O, amino acid, water, optional FeO, optional MnO and optional humic acid, and can block the growth of hyphae, interfere with the germination of spores, stimulate the generation of phytoalexin and the like, improve the resistance of plants to germs, and provide nutrient substances necessary for the growth and development of the plants, and the absorption of plants on nutrientsubstances is promoted.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a powdery mildew control synergistic agent, a synergistic method and application of the agent for preventing and controlling powdery mildew. Background technique [0002] Melon powdery mildew is caused by the fungus G.cichoracearum DC of the genus Erysiphyta of the family Ascomycota and the genus S.fuliginea (schlecht.) poll. It is the most common disease in melon production. A major disease. Although powdery mildew can be controlled chemically, it is difficult for conventional chemical agents to achieve the ideal control effect due to the large number of physiological races that harm melon powdery mildew and rapid differentiation. [0003] Several mainstream fungicides currently on the market for the treatment and prevention of melon powdery mildew have been continuously used by farmers in recent years, and the resistance of the bacteria has increased. Therefore, it is v...
