Abstract
The invention discloses low volume spray containing diafenthiuron and tolfenpxrad, and relates to pesticide. The low volume spray containing diafenthiuron and tolfenpxrad is composed of, by mass, 10%-50% of diafenthiuron, 1%-20% of tolfenpxrad, 5%-15% of tea saponin, and the balance water. During preparation, the water and the tea saponin are added into a deploying kettle to be evenly mixed, and then the diafenthiuron and the tolfenpxrad are added to be fully dispersed in mixed liquor of the water and the tea saponin; afterwards, a sand mill is used for grinding, sampling detection is qualified, and filling package is conducted. The water and the tea saponin are used as carriers, so that people and livestock are safe, no phytotoxicity on crops can be easily caused, and safety and environmental protection are achieved. The formula is simple, the water is used as the carrier, so that cost is low, and cost performance is high. The dilution water consumption of drugs is small, and the low volume spray is particularly suitable for mist spraying in dry and high mountain water-deficient areas. The low volume spray is used for low volume and ultra-low volume mist spraying, the work efficiency is high compared with constant quantity mist spraying, and labor cost is saved. Dripping loss of liquor is small, the pesticide utilization rate 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 diafenthiuron and Tolfenpyrad.
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 (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 CN103271051A discloses a kind of Tolfenpyrad and the composite Pesticidal combination with synergistic function of diafenthiuron, said composition is made up of Tolfenpyrad and diafenthiuron two kinds of active ingredients and auxiliary agent or carrier, wherein the mass ratio of Tolfenpyrad and diafenthiuron is 30:1 ~ 1:30, and Tolfenpyrad and diafenthiuron gross mass mark is in the composition 5% ~ 80%.
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 diafenthiuron and Tolfenpyrad is provided.
The present invention's raw material by mass percentage consists of: diafenthiuron 10% ~ 50%, Tolfenpyrad 1% ~ 20%, Tea Saponin 5% ~ 15%, and surplus is water.
The present invention's raw material composition is by mass percentage preferably: diafenthiuron 15% ~ 45%, Tolfenpyrad 5% ~ 15%, 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 diafenthiuron and Tolfenpyrad, 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.
