Abstract
A low-volume spray containing azadirachtin relates to pesticides, and comprises the following raw materials by mass: 0.3 to 3 percent of azadirachtin, 5 to 15 percent of tea saponin, and the balance of water. During preparation, water and natural tea saponin are added into a preparation kettle for uniform mixing, then azadirachtin is added to sufficiently disperse in the mixture liquid, then milling with a sand mill is carried out, sampling for qualification detection is performed, and filling package is carried out. As water and natural tea saponin are adopted as carriers, the low-volume spray is safe to people and livestock, low in possibility of causing phytotoxicity to plants, safe and environmentally friendly. The formula is simple, and water is taken as a carrier, so that the cost is low, and the performance cost ratio is high. As the quantity of water used for dilution is low, the low-volume spray is particularly suitable for spraying in arid regions and water-shortage high mountain regions. As the low-volume spray can be used for low-volume spraying and super-low-volume spraying, the spraying efficiency is higher than that of a medium volume spraying, and manual cost is reduced. The loss of spray caused by drippage is low, so that the pesticide utilization ratio is high, and environmental pollution is reduced.
Description
Technical field
The present invention relates to agricultural chemicals, especially relate to a kind of low-gallonage spraying agent containing nimbin.
Background technology
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 (667cm
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, and every mu of spouting liquid, at 45 ~ 60L, is 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 is with water or oil dilution, and extension rate about 100 times, every mu of spray liquid amount 5 ~ 15L, is 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 is with water or oil dilution, and extension rate is lower than 10 times, and every mu of spouting liquid is 0.5 ~ 2.5L, is called ultra low volume spray, and spray amount is very low, and work efficiency is 10 ~ 50 times of conventional spray, and agricultural chemicals runs off seldom, and availability can reach more than 80%.
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 CN103651506A discloses the Pesticidal combination of penta pyrrole worm guanidine and azadirachtin complex, the two compositely can be prepared into the formulation be agriculturally suitable for, such as missible oil, wetting powder, water dispersible granules, suspending agent, oil-suspending agent, ultra low volume liquids, electrostatic oil agent or dry suspending agent, in order to control relevant insect agriculturally, the generation of pest resistance can be delayed, reduce insecticide usage amount, environmentally safe.
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 containing nimbin is provided.
The present invention's raw material by mass percentage consists of: nimbin 0.3% ~ 3%, Tea Saponin 5% ~ 15%, and surplus is water.
The present invention's raw material composition is by mass percentage preferably: nimbin 0.3% ~ 2%, 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 nimbin, 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.
