Titanium-sulfur powdery mildew prevention mixture

Abstract

The invention relates to a titanium-sulfur powdery mildew prevention mixture. The mixture comprises the following ingredients: 3 to 5 parts of shell-core structure 70-nm titanium microspheres, 6 to 10 parts of sulfur and 30 to 50 parts of 27% lipid film. The mixture is processed into emulsion and mainly used for preventing pumpkin powdery mildew, pepper powdery mildew and strawberry powdery mildew. According to the mechanism of action of the titanium-sulfur powdery mildew prevention liquid, a fatty acid film is formed on a leaf to prevent the invasion of germs and prevent the growth diffusion of the germs on a disease part and to produce little heat under the sunlight so as to damage the protective film and cell wall of germs, infect the wound of the germs by the sulfur which is sensitive to the germs, to alleviate the activity and diffusion of the germs and to kill the germs are further killed, so that the titanium-sulfur powdery mildew prevention mixture is a physical prevention method; in addition, an effect on preventing sunscald caused by high-intensity sunlight and improving photosynthesis and hydrophilia can be achieved. The titanium-sulfur powdery mildew prevention mixture is a safe, environment-friendly, toxic-free and no-drug-fast powdery mildew prevention mixture.

Description

technical field [0001] The invention relates to a titanium-sulfur powdery mildew control agent, which belongs to the technical field of plant disease and insect pest control. Background technique [0002] The pathogenic bacteria of powdery mildew are easy to produce drug resistance. The prevention and control of powdery mildew generally adopts the systemic conduction method to destroy the glyceraldehyde triphosphate deoxygenase of the powdery mildew pathogen, and combine with the cysteine ​​protein of the enzyme, thereby The principle of destroying the protease activity, destroying the metabolism of the powdery mildew pathogen and losing life; using this principle of prevention and control method is likely to cause pesticide residues and drug resistance with the powdery mildew pathogen; use physical control methods to seal the pathogen to avoid It diffuses, reduces its respiratory function, destroys its protective film and cell wall with sunlight, and can provide trace eleme...

[0002] The pathogenic bacteria of powdery mildew are easy to produce drug resistance. The prevention and control of powdery mildew generally adopts the systemic conduction method to destroy the glyceraldehyde triphosphate deoxygenase of the powdery mildew pathogen, and combine with the cysteine ​​protein of the enzyme, thereby The principle of destroying the protease activity, destroying the metabolism of the powdery mildew pathogen and losing life; using this principle of prevention and control method is likely to cause pesticide residues and drug resistance with the powdery mildew pathogen; use physical control methods to seal the pathogen to avoid It diffuses, reduces its respiratory function, destroys its protective film and cell wall with sunlight, and can provide trace elements needed for crop growth; for pesticide residues, it is necessary to provide a physical protection against powdery mildew damage.
