Abstract
The invention provides a pesticide suspension comprising effective amount of active components of iprodione and dimethomorph as well as a wetting agent, a dispersing agent, a defoaming agent, a thickening agent, a preservative and water with or without an antifreeze agent, wherein the wetting agent is one or more of alkylphenol formaldehyde resin polyethenoxy ether, polyether modified polysiloxane, fatty alcohol-polyoxyethylene ether and nekal. The iprodione and dimethomorph pesticide suspension is prepared by selecting the suitable wetting agent and compounding with other additives, has highsuspension rate and good stability, lowers the resistance risk of using the compound and enables the compound to have control effect obviously superior to that of a single preparation.
Description
Technical field
The invention belongs to technical field of pesticide, relate in particular to a kind of agricultural chemicals suspension agent.
Background technology
Iprodione is a kind of broad spectrum activity contact killing type protective fungicide, but its both sprouting and generation of Antifungi spore also can be controlled mycelial growth, and is namely all influential to disease fungus each developmental stage in the history of life.Main controlling object is various crop, fruit tree and the fruit storage phase disease that Botrytis, Monilia, Penicillium, Sclerotinia, Alternaria, Helminthosporium, Rhizoctonia, Phoma, mycosphaerella, Cercospora etc. cause, such as the gray molds of the stalk break on grape grey mould, the tone fruit trees, alternaria leaf spot of apple, Pear black spot, early blight of tomato, strawberry, vegetables etc.Although iprodione diseases prevention spectrum is wide, safety, preventive effect, its result for the treatment of is relatively poor, often wants the remarkably productive drug use of partner treatment.
Dimethomorph is single-minded ovicidal Gammaproteobacteria fungi bactericide, its effect characteristics are to destroy the formation of cell envelope, stages to oomycetes history of life has effect, formation stages at sporangiophore and egg spore is particularly responsive, (＜0.25 μ g/ml) namely is suppressed under extremely low concentration, and result for the treatment of is outstanding.But use separately higher resistance risk is arranged, thus normal and the composite use of protective fungicide, with the generation of delaying drug resistance.
In process of crop growth, when usually can be subject to multiple various pathogenic bacteria or in succession infect harm, this requires control medicament that wider activity profile is arranged.Obviously, the independent use of iprodione or dimethomorph all can not reach this requirement.
At present, also not about the report of the suspending agent of iprodione and dimethomorph.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of suspensibility high, good stability, and also the composition for preventing and controlling successful is better than the agricultural chemicals suspension agent of single dose.
The embodiment of the invention is to realize like this, a kind of agricultural chemicals suspension agent, the active component iprodione and the dimethomorph that comprise effective dose, and wetting agent, dispersant, defoamer, thickener, preservative and water, contain or do not contain antifreeze, wherein, wetting agent is alkyl phenol formaldehyde resin polyoxyethylene ether, polyether-modified polysiloxane, fatty alcohol-polyoxyethylene ether and pull open in the powder one or more.
Compared with prior art, technique scheme is selected suitable wetting agent, cooperates other auxiliary agent to make the suspending agent of iprodione and dimethomorph, referring to embodiment table 1 and table 2 data, this suspending agent suspensibility is high, good stability, and the composition for preventing and controlling successful is better than single dose.In addition, owing to using composition, its resistance risk has also reduced.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The agricultural chemicals suspension agent of the embodiment of the invention comprises active component iprodione and the dimethomorph of effective dose, and wetting agent, dispersant, defoamer, thickener, preservative and water, contains or do not contain antifreeze.Wherein, wetting agent is alkyl phenol formaldehyde resin polyoxyethylene ether, polyether-modified polysiloxane, fatty alcohol-polyoxyethylene ether, pull open one or more in the powder, preferred alkyl fluosite APEO, one or more in polyether-modified polysiloxane and the fatty alcohol-polyoxyethylene ether.
More specifically, above-mentioned suspension agent composition, each component and weight content thereof are as follows:
Iprodione 5-30%
Dimethomorph 5-30%
Wetting agent 1-5%
Dispersant 2-8%
Antifreeze 0-10%
Defoamer 0.1-2%
Thickener 0.1-3%
Preservative 0.1-3%
Water supplies 100%.
There is no particular restriction for the antifreeze of the embodiment of the invention, for this area antifreeze commonly used, for example, can select one or more in ethylene glycol, propane diols, glycerine, glycerine, the urea.
