Abstract
The invention discloses an oxadiargyl and cyhalofop-butyl oil suspoemulsion. The oxadiargyl and cyhalofop-butyl oil suspoemulsion comprises the following components in percentage by weight: 1-25% of oxadiargyl, 1-20% of cyhalofop-butyl, 0.1-5% of a dispersant, 1-20% of an emulsifier, 0.1-2% of a thickening agent and the balance of vegetable oil. The preparation method comprises the following steps: firstly preparing an oxadiargyl oil suspension, then uniformly dispersing cyhalofop-butyl and the emulsifier by using a high-speed homogenizer, then adding the substance obtained by dispersing into the oxadiargyl oil suspension and uniformly mixing. The preparation method disclosed by the invention is simple and easy to operate and very high in storage, transportation and use safety; and by using the preparation method, the biological activity is improved, the control range of a herbicide is expanded, the production and using cost is reduced relative to an original single agent, and the oxadiargyl and cyhalofop-butyl oil suspoemulsion is environmentally friendly and in line with the development direction of current pesticide formulations.
Description
Technical field
The present invention relates to formulations of pesticide manufacture field, be specifically related to a kind of Bing Que Evil humulone and cyhalofop-butyl oil suspended emulsion and preparation method thereof.
Background technology
Third alkynes Evil humulone is the one novel oxadiazole nitrogen-containing hetero lopps weed killer herbicide of Rhone-Poulenc Company's exploitation, for high-efficiency broad spectrum herbicides for use in paddy, the weeds such as mexicana, duckweed, the water silk floss of algae, little najas marina, beggar-ticks, Chenopodium weeds, Siberian cocklebur, Monochoria vaginalis, Polygonum weeds, black nightshade, common sow thistle in annual and perennial barnyard grass gramineous, the difformed galingale herb of sedge family, needle spikesedge herb, broadleaved herb can be prevented and kill off, prevent and kill off broad leaved weed before being mainly used in the seedlings such as paddy rice, potato, sunflower, vegetables, beet, orchard, application is very extensive.
Cyhalofop-butyl is only kind paddy rice to tight security in aryloxyphenoxypropionic class weed killer herbicide, the same with such other kinds, is also Uptake and translocation weed killer herbicide.Cyhalofop-butyl is that current paddy field applies more selective herbicide, is mainly used in preventing and kill off important grassy weed, efficient to moleplant seed, has certain preventive effect, also can prevent and kill off lady's-grass, Paspalum distichum, green foxtail, eleusine indica, amur foxtail etc. to low age barnyard grass.To sedge weed and broad leaved weed invalid.
Oil suspended emulsion is a kind of relatively new complex system, and being oil-suspending agent and environmental protection missible oil combined system, take oil as continuous phase (dispersion medium).The safety of processing, storing and use procedure is all good, there is not the problems such as poisonous hazardous solvent contaminated environment.It is that medicament for adapting to have different physicochemical property needs used in combination and grow up; Make will to be processed into routinely medicament that two kinds of formulations could use with to become and be processed into a formulation and can use, greatly reduce the usage amount of pharmaceutical auxiliary agent and packaging material, be also beneficial to storing and use.
Oil suspended emulsion is the mixed type formulation of oil-suspending agent and environmental protection missible oil, has the characteristic of oil-suspending agent and environmental protection missible oil, has following unique advantage:
(1) potion multiple-effect.Oil suspended emulsion can be loaded in several active component bag in oil phase in system or solid phase, so just can play the effect of potion multiple-effect.
(2) biologically active is high.Oil suspended emulsion can wrap simultaneously carry various active composition, makes to have each component that is collaborative or synergistic effect and is present in same system, expand the prevention and treatment range of preparation, thus improve biologically active.
(3) slow releasing function.Oil suspended emulsion can delay or Drug controlled release, solid drugs can be made suspended emulsion formulation, plays long-acting.
(4) prepare simple, easy to use.
It is actually rare that current oily suspended emulsion is used for agricultural chemicals.The main formulation of existing Bing Que Evil humulone is based on wetting powder and water dispersible granules, the main formulation of cyhalofop-butyl is based on missible oil, aqueous emulsion and microemulsion, both combination of active principles are prepared into the novel form of oily suspended emulsion by the present invention, and there is not been reported for the formulation of this kind.
Summary of the invention
The object of the present invention is to provide a kind of production, storing, use safety, environment-friendly type, the Bing Que Evil humulone that availability is high and cyhalofop-butyl oil suspended emulsion and preparation method thereof, overcoming environmental pollution that existing weed killer herbicide exists, be detrimental to health, the shortcoming such as the high and biologically active of use cost is low.
The technical solution used in the present invention is as follows:
A kind of Bing Que Evil humulone and cyhalofop-butyl oil suspended emulsion, the percentage by weight of each component is: Bing Que Evil humulone 1-25%, and cyhalofop-butyl 1-20%, dispersant 0.1-5%, emulsifier 1-20%, thickener 0.1-2%, surplus is vegetable oil.
