Description
Technical field
The invention belongs to technical field of pesticide, particularly a kind of ultra low volume liquids that contains fluorine pyridine urea.
Background technology
At present, the agricultural chemicals liquid formulation is main with missible oil.A large amount of uses of organic solvent not only cause the waste of industrial chemicals in the missible oil process, return environment and human health simultaneously and have brought very big threat.In recent years, some developed countries have proposed to forbid missible oil, and China has also put into effect registration and the production that relevant policies limit missible oil at present.In addition, along with the improvement of planting patterns, the increase of labor cost, laborsavingization formulation will be one of important directions of following formulations of pesticide development.
Ultra low volume liquids is a kind of novel labour saving chemical preparation of developing in recent years, and consumption is few, and is easy to use, have province's medicine, laborsaving, not water, good drug efficacy, hold and imitate advantages such as long.Ultra low volume liquids is low through the screening volatility, flash-point is high, to former medicine dissolubility is good, low to chemical injury of crops, viscosity is low solvent; Do not convert water during dispenser, but directly use with ultra low volume sprayer tool, low-gallonage spraying apparatus or ultra low volume electrostatic spray apparatus.Ultra low volume spraying is not owing to contain the high volatile volatile composition in the droplet, and its size does not have significant change from leaving the spraying apparatus to arriving the target process with quality, has reduced volatilization with elegant.Droplet is tiny and even, meets " biological best granula " requirement, has significantly improved deposition.Because need not to convert water uses, ultra low volume liquids is suitable for water scarcity, damage by disease and insect fulminant large tracts of land takes place and the occasion of dispenser on a large scale in the palpus short time, and ultra low volume spraying has simultaneously greatly reduced operator's labour intensity.Comprehensive it, the ultra low volume spraying technology has the following advantages: 1. spouting liquid is few, is merely hundreds of/one of conventional spraying.2. droplet is little, and ultra low volume electrostatic spray fogdrop diameter is that 30～60 μ m, ultra low volume ground spraying droplet diameter are 30～80 μ m, aerial ultra low volume spraying fogdrop diameter 30～60 μ m, and conventional spraying droplet diameter is many more than 200～600 μ m.3. spray pattern is the spraying of drift accumulation property, and conventional spraying is the specific aim spraying, promptly facing to the crop spraying.What 4. ultra low volume sprayed is to be the finish of carrier with oil, and concentration is generally a few percent to percent tens; And the conventional water diluent agent concentration that sprays is very low, is generally some thousandths of to ten thousand/several.5. work efficiency is high, and control is timely: hand-held ultra low volume spraying machine improves 20～30 times of work efficiency than manual compression sprayer, because of its work efficiency is high, can timely and effectively prevent and treat the fulminant insect, like plant hopper, mythimna separata, locust etc.6. save agricultural chemicals: save agricultural chemicals more than 30% with general conventional spraying ratio.7. water not: saved water intaking, made up a prescription and heavy physical labor such as negative water operation, the hilly and mountainous land of especially short of rain in arid, manpower shortage and water intaking difficulty is used, and is more convenient.8. good drug efficacy, hold imitate long: oily agricultural chemicals is easy to penetrate ester dissolubility insect body surface and gets in the pest body, show as desinsection rapidly, good drug efficacy; The high boiling point auxiliary agent that occupies larger proportion in the finish can play protective effects such as anti-hydrolysis, anti-oxidant, anti-photodissociation to pesticide active ingredient, show as hold imitate long.9. to crop safety: ultra low volume spraying be difficult for to produce poisoning to crop safety, does not have obviously residually, can improve crop quality.
expenses for prevention and control is low: since ultra low volume spraying have province's medicine, laborsaving, not water, good drug efficacy, hold and imitate advantages such as long, so expenses for prevention and control is lower than conventional spraying.
At present for the insect that is prone to produce resistance on the agricultural; Main prevention and treatment method is that exploitation and existing kind do not have composite between new composition or the existing pesticide species of cross resistance; The former is because required development cost is high, the cycle is long; And development rate is far away less than the speed of pest resistance to insecticide generation at present, and therefore, being mixed for the different existing pesticide species of the mechanism of action is a kind of selection of the best.If select agricultural chemicals and reasonable mixture ratio, then can produce significant synergistic effect, make field control effect significantly be superior to the effect of each single agent, not only practice thrift the control cost, also can effectively delay the generation of pest resistance to insecticide, prolong the service life of new component.
Summary of the invention
The object of the present invention is to provide a kind of ultra low volume liquids that contains fluorine pyridine urea, easy to process, environmentally friendly, easy to use, water-saving have quick-acting and long lasting period preferably, reduce the access times and the dosage of agricultural chemicals, practice thrift cost of labor.
