Abstract
The invention provides dichloropenconazole wettable powder which comprises an effective amount of active component-dichloropenconazole, a wetting agent, a dispersant and fillers. The prepared dichloropenconazole wettable powder is high in suspension rate and stability.
Description
Technical field
The invention belongs to technical field of pesticide, bactericide dichloro dislikes the wetting powder of bacterium azoles.
Background technology
For the great disease problem of agricultural, carry out the guide structure optimizing research of disease regulation and control, find safety scientific and efficiently and have green candidate's agricultural chemicals of potential market vitality to be the vital task faced in China's New pesticides discovery basic research.Guide finds it is the key realizing innovation green chemical pesticide, and design optimization synthesizes some class agricultural chemicals guide structures, the green chemical pesticide of development of new low toxicity, low-residual, safety, seems very urgent and important.Guizhou University has found that dichloro dislikes bacterium azoles (Universal Chinese character name, the Secretariat of national pesticide standard technical committee names), molecular formula: C
9h
6cl
2n
2o
3s.
Under 75-150 gram/ha of consumption, dichloro is disliked bacterium azoles and is had excellent preventive effect (test approval number: SY201301945) to fungal diseases such as potato late blight.
Dichloro dislikes bacterium azoles physicochemical property: molecular weight 293.1.Former medicine is acicular crystal, water insoluble, is soluble in conventional organic solvent.Former medicine, to light, thermally-stabilised, easily decomposes under alkali condition (pH10).
Dichloro dislikes bacterium azoles mammalian toxicity: rat acute per os LD
50=1780mg/kg.Rat acute is through skin and suck LD
50>2000mg/kg.
The present invention is the wetting powder that open dichloro dislikes bacterium azoles.It is that dichloro dislikes bacterium azoles, inert filler and a certain amount of auxiliary agent that dichloro dislikes bacterium azoles wetting powder, in proportion after abundant co-grinding, reach the formulation of certain particle size, add the auxiliary agent such as wetting agent, dispersant, be added to after in water and can be readily wetted by water, disperse, form suspension, can spray and use.
Summary of the invention
The object of the invention is to invent a kind of pesticide wettable, the active component dichloro including effective amount dislikes bacterium azoles, and other are wetting agent, dispersant and filler, the weight percent proportioning of each component is: dichloro dislikes bacterium azoles 20-45%, lubricant 1.5-3.5%, dispersant 4-5%, filler is supplemented to 100%.
It is characterized in that described wetting agent is ethoxylated dodecyl alcohol or detergent LS.
Described dispersant is calcium lignosulfonate or sodium metnylene bis-naphthalene sulfonate.
Described filler is selected from one in kaolin, diatomite, bentonite, white carbon, starch or 2-3 kind.
Embodiment
Embodiment 1 20% dichloro dislikes bacterium azoles wetting powder
Weigh dichloro and dislike bacterium azoles (content 93%) 21.8g, ethoxylated dodecyl alcohol 2g, calcium lignosulfonate 4g, diatomite 72.2g fully mixes, disperses, be crushed to particle diameter fineness 99.5% by 325 mesh sieves, obtain 20% dichloro and dislike bacterium azoles wetting powder.
Embodiment 2 30% dichloro dislikes bacterium azoles wetting powder

Embodiment 3 40% dichloro dislikes bacterium azoles wetting powder
Weigh dichloro and dislike bacterium azoles (content 93%) 43g, detergent LS3.5g, sodium lignin sulfonate 5g, diatomite 48.5g, fully mixing, dispersion, be crushed to particle diameter fineness 99.5% by 325 mesh sieves, obtains 40% dichloro and dislike bacterium azoles wetting powder.
The performance of embodiment 4 wetting powder
With reference to GB/T14825-2006, with standard hard water, sample to be tested is mixed with the suspension of debita spissitudo, under prescribed conditions, in amount letter, leaves standstill 30 min, measure the content of active ingredient in 1/10 suspension of bottom, calculate suspensibility; With reference to GB/T 19136-2003, be sealed in by the powder samples of preparation in the dark glass bottle of band grinding port plug, in (54 ± 2) DEG C insulating box, preserve 14 d, before and after storage, marks, cracks or perforations on rocks made by action of waves determines the content of active ingredient respectively, calculates resolution ratio.Dislike bacterium azoles wettable powder the key technical indexes to dichloro of the present invention to measure, it is as shown in the table for result:
| Numbering | Effective content (%) | Fineness | Suspensibility (%) | Moisture | Heat storage stability |
| Embodiment 1 | 20.2 | 325 orders | 88.5 | Qualified | Qualified |
| Embodiment 2 | 30.1 | 325 orders | 90.8 | Qualified | Qualified |
| Embodiment 3 | 40.5 | 325 orders | 81.2 | Qualified | Qualified |
Conclusion
The present invention is that a kind of dichloro dislikes bacterium azoles wetting powder, and wettable powder better performances, indices meets the requirements.
