Description
Technical field
The present invention relates to weed killer herbicide suspension agent that a kind of methyl two sulphurs are grand and alkynes oxalic acid is composite and preparation method thereof, belong to technical field of pesticides.
Background technology
Pesticidal preparations is progressively to safe, environmental protectionization, water baseization development, and 1. agricultural chemicals suspension agent does not have dust harzard owing to have the following advantages, to operator and Environmental security; 2. be dispersion medium with water, do not have the inflammable and drug injury problem that produces by organic solvent; 3. compare with wetting powder, allow to select for use the former medicine of different-grain diameter, so that make the biological effect of preparation and physical stability reach best; 4. liquid suspension spreads in water well, can directly make spray liquid and use; 5. than great, packaging volume is little.6. the dispersiveness of suspending agent and plate-out ability are all relatively good, the suspensibility height, and the ability that sticks to the plant corpus surface is more intense, resistance of rainwater washing against, thereby drug effect significantly and also compares lastingly than wetting powder.7. have that particle is little, active surface is big, penetration is strong, do not have dust when making up a prescription, characteristics such as cost is low, drug effect height.And have the advantage of wetting powder and missible oil concurrently, and can be moistening by water, suspension is good behind the thin up.Agricultural chemicals suspension agent be after a kind of formulation of large usage quantity in the formulations of pesticide utilizations.
Alkynes oxalic acid, chemical name: (R)-2-[4-(5-chloro-3-fluoro-2-pyridine oxygen base) phenoxy group] the propionic acid propargyl ester, it is the fluorine-containing high-efficiency low-toxicity weed killer herbicide of phenoxy carboxylic acid chirality, effective especially to pernicious grassy weed, mix with certain proportion with safener, be used for cereal crop, grassy weed such as Salvia japonica, amur foxtail, wild oat, perennial ryegrass, annual bluegrass, green foxtail etc. are had excellent preventive effect.The mode of action: wide spectrum grassy weed foliar herbicide behind the interior absorption seedling.The mechanism of action: the mechanism of action of alkynes grass ester is for suppressing the activity of acetyl-CoA carboxylase in the plant corpus, be interior suction conductivity weed killer herbicide, blade and leaf sheath by plant corpus absorb, the phloem conduction accumulates in the meristematic tissue of plant corpus, suppresses acetyl-CoA carboxylase, fatty acid is synthesized to be stopped, the growth division of cell can not normally be carried out, and film system etc. contains the fat structural deterioration, causes plant death at last.
Mainly be missible oil and water-dispersible granules on the alkynes oxalic acid market at present.
Methyl two sulphurs are grand, chemical name: 2-[3-(4,6-dimethoxypyridin-2-yl) urea sulphonyl]-4-Methanesulfomide methyl toluate sulfonylurea inner sucting conduction type seedling after selective herbicide, be the inhibitor of acetolactate synthase.Grass cutting blade promptly stops growing after absorbing medicament, withered gradually.The longevity of residure of this medicine in soil is short, does not influence the second stubble crop growth.Be mainly used in wheat, naked barley etc. remove grassy weed and some broad leaved weed.
But the grand preparation of methyl two sulphurs of present domestic registration mainly be oil-suspending agent and and the dispersed oil suspending agent and the water-dispersible granules of other weed killer herbicide agriculture chemical compounding, do not see the weed killer herbicide suspension agent composite with alkynes oxalic acid.
