Description
Technical field
The present invention relates to a kind of compositions preventing and treating soil-borne disease, former particularly to one preventing and treating root-knot nematode, soil-borne disease
Fungus and the compositions of weeds.
Background technology
Nearly ten years, along with the adjustment of agricultural planting structure, Protectorate cultivation has had in China and has developed by leaps and bounds.The whole nation is protected
Protect ground area more than 2,000,000 hectares.And Protectorate cultivation is increased farmers' income as one in China, by traditional agriculture to existing
The Important Agricultural measure that generation agricultural changes, will develop continuation in future, and the crop of cultivation is also by by current vegetable, Fructus Fragariae Ananssae
Develop to directions such as flowers, melon, fruit tree, nursery, Chinese herbal medicine.The development of protecting field, is also root-knot nematode, soil-borne disease and miscellaneous
The generation of grass, development provide suitable environment, and after generally planting 3～5 years, the yield and quality of crop is by serious shadow
Ringing, the general underproduction 20～40%, Severe Reduction more than 60% even has no harvest.Along with continuation development and the high added value of protecting field are made
The cultivation year after year of thing, the problem of root-knot nematode, soil-borne disease and weeds will be more and more prominent, and will become and seriously restrict protecting field
The key factor of development.According to us in Shandong, Jiangsu, Liaoning, Hebei, Zhejiang, the investigation of the ground such as Henan, root-knot nematode, soil-borne disease
The harm of evil and weeds has become the outstanding problem in Protectorate cultivation.Due to without effectively preventing method, in ground agricultures such as Shandong
The people use medicament (such as Aldicarb, carbofuran, thimet etc.) preventing and treating root-knot nematode, soil-borne disease and the weeds of country's disabling in a large number
Deng, the life and health of serious harm people.Owing to protecting field investment is big, some process time length, need the longer crop rotation time
Method is difficult to carry out in greenhouse, it is also difficult to accepted by peasant.And soil chemistry disinfection technology is increasingly becoming current guarantor before planting
Protect one of one preferred technique of ground agriculture plant protection.
Ethyl formate has distinctive peppery pungent taste and the Fructus Ananadis comosi sample fragrance of similar ethyl acetate, have spirit happy, clear,
Elegant, gentle Rum is fragrant, and extension is good, but fragrance remaining time is of short duration, micro-strip bitter taste.Ethyl formate is to allow to use
Flavorant, its chemical constitution has active carbonyl and ester group character, has reproducibility, can carry out ester condensation reaction, can be miscible
In ethanol, ether, benzene and propylene glycol, being slightly soluble in mineral oil and water, easy firing, steam can form explosive mixture with air.
Insoluble in glycerol, alkalescence is easily hydrolyzed into free acid and ethanol.Human body is safe from harm by Ethyl formate, is mainly used in food
Product technical field, does not the most develop at pesticide field.
Summary of the invention
