Abstract
The invention discloses a cyhalothrin-containing low-volume spray and relates to pesticides. The spray comprises the following raw materials in percentage by mass: 2.5-30% of cyhalothrin, 5-15% of tea saponin and the balance of water. During preparation, water and tea saponin are added into a blending kettle for uniform mixing, and then cyhalothrin is added to ensure that cyhalothrin sufficiently disperses in the water and tea saponin mixed solution; milling with a sand mill is carried out, sampling for qualification inspection is performed, and filling package is carried out. Water and tea saponin are taken as carriers, so that the spray is safe to human and animals, low in phytotoxicity to crops, safe and environmentally friendly; the formula is simple and water is taken as the carrier, so that the cost is low and the cost performance is high; the consumption of water for pesticide dilution is low, so that the spray is particularly suitable for arid regions and water-deficient high mountain regions; the spray can be applied to low-volume and super-low-volume spraying; compared with the normal-volume spraying, the low-volume and super-low-volume spraying are higher in working efficiency and lower in labor cost; the liquid pesticide dropping loss is low and the pesticide utilization ratio is high, so that the environmental pollution is reduced.
Description
Technical field
The present invention relates to agricultural chemicals, especially relate to a kind of low-gallonage spraying agent of containing chlorine fluorine Cyano chrysanthemate.
Technical background
The medical treatment of diseases and pests of agronomic crop and sanitary insect pest, spray-on process is modal application method, is namely made into liquid with a certain amount of agricultural chemicals and appropriate water or oil, with spraying apparatus, medicine liquid spray is become droplet.By every mu of (667m
2) number of spray liquid amount, spray-on process is often divided into conventional spray, low volume and ultra low volume spray.
1, conventional spray, agricultural chemicals dilutes with water, and extension rate is greater than 1000 times, every mu of (667m
2) spouting liquid at 45 ~ 60L, be the conventional spray-on process in present stage China's plant protection field.This spray-on process spray amount is large, and work efficiency is not high, and liquid drippage runs off serious, and agricultural chemicals availability is less than 30%.
2, low volume, agricultural chemicals dilutes with water or oil, extension rate about 100 times, every mu of (667m
2) spray liquid amount 2.6 ~ 10L, be called low volume.This spray-on process, spray amount is lower, and work efficiency is 5 ~ 10 times of conventional spray.Agricultural chemicals runs off few, and availability can reach more than 60%.
3, ultra low volume spray, agricultural chemicals with water or oil dilution, extension rate lower than 10 times, every mu of (667m
2) spouting liquid is 0.5 ~ 2.5L, be called ultra low volume spray, spray amount is very low, and work efficiency is 10 ~ 50 times of conventional spray, and agricultural chemicals runs off seldom, utilizes the control of China's plant protection field crop disease and insect, at present still based on conventional spray.Because its droplet is large, target produces spring, drippage runs off serious, and agricultural chemicals availability is not high, to environment, also can make that agricultural product agriculture is residual to exceed standard; Again because its spray amount is large, spraying work efficiency is low, and cost of labor is also high; Conventional spray agent dilute with water multiple is greater than 1000 times, and water consumption is large, is unfavorable for that arid and high mountain water-deficient area use.
It is worth mentioning that, conventional spray agent with dimethylbenzene etc. to the organic solvent of human body and bad environmental and petrochemical industry class surfactant for carrier, safety and the feature of environmental protection are all bad, all can produce harm to human body and crop, can not in order to low amounts and ultra low volume spray; For realizing the accurate high-efficiency prevention and control of diseases and pests of agronomic crop, reducing agricultural chemicals and running off, reducing the pollution to environment and agricultural product, improving agricultural chemicals availability, improve spraying work efficiency, the agent of research and development low-gallonage spraying, very necessary.
Chinese patent CN101606532B discloses cyhalothrin and the orthene Recompounded pesticide of a kind of main control cotton-plant pest-insects cotton bollworm.Represent with percentage by weight, containing cyhalothrin 1-5%, orthene 32-39%, add emulsifier and antifreezing agent, then adding water complements to 100%.Cyhalothrin and orthene are carried out composite rear Toxicity Determination show, product nitrate enhancement is 199.14, belongs to remarkable synergy, use this medicine can greatly reduce the control number of times of cotton bollworm, improve control rate, can reduce labor intensity simultaneously, reduce environmental pollution.This invention formulation is microemulsion, uses water as solvent, can save a large amount of organic solvent, improve the safety of product.Composite rear product toxicity reduces, and reduces production cost, ensure that control efficiency expands controlling object simultaneously, can improve doublely to control effect, and extend the longevity of residure, the cost performance of product improves greatly.
Obviously, existing medicament all adopts traditional organic solvent usually, all there is potential safety hazard, can not be used for the low-gallonage spraying of high-load liquid to human body, plant, environment etc.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of low-gallonage spraying agent of containing chlorine fluorine Cyano chrysanthemate is provided.
The present invention's raw material by mass percentage consists of: cyhalothrin 2.5% ~ 30%, Tea Saponin 5% ~ 15%, and surplus is water.
The present invention's raw material composition is by mass percentage preferably: cyhalothrin 2% ~ 25%, Tea Saponin 10% ~ 15%, surplus is water.
During use, with low-capacity atomizer spraying, dilute with water 1 ~ 100 times, for low amounts and ultra low volume spray, the medicine liquid spray amount 1 ~ 10L of every mu, for the control of plant pest and the dissipation of sanitary insect pest.
During preparation, water and Tea Saponin are added compounding kettle and mixes, then add cyhalothrin, be well-dispersed in water and Tea Saponin mixed liquor, then with sand mill grinding, sample detection qualified, filling and package.
Compared with prior art, the present invention has the following advantages:
1. with water and natural tea saponin powder for carrier, to person poultry safety, be not easy to produce poisoning, safety and environmental protection to crop.
2. formula is simple, and be carrier with water, cost is low, and cost performance is high.
3. medicament thinned water amount is few, is particularly useful for the spraying of arid and high mountain water-deficient area.
4. can be used for low capacity and ultra low volume spraying, higher than conventional spray work efficiency, save cost of labor.
5. liquid drippage runs off few, and agricultural chemicals availability is high, reduces environmental pollution.
