Abstract
The invention relates to a chlorthal water dispersible granule and a preparation method thereof, and the chlorthal water dispersible granule is characterized by comprising the following components by weight percent: 1-95% of chlorthal, 1-5% of wetting and dispersing agent, 1-5% of dispersing agent, 1-3% of disintegrating agent, 1-2% of bonding agent and 1-80% of carrier. The preparation method comprises the following steps: fully mixing auxiliary materials, a filling material and chlorthal raw medicines by weight percent in a mixer in a certain proportion, then placing into an airflow pulverizer for pulverization, then performing secondary mixing and secondary pulverization, then spraying water, extruding, granulating and drying, thus obtaining the chlorthal water dispersible granule. The chlorthal water dispersible granule can be used for not only treatment before germination but also stem-leaf spraying. The chlorthal water dispersible granule is suitable for corn, soybeans, kidney beans, cucumbers, onions, peppers, strawberries, lettuces, eggplants, turnips and other crops, as well as lawns and ornamental plants. The chlorthal water dispersible granule is mainly used for preventing and removing annual grass weeds and certain broadleaf weeds, such as green bristlegrass, digitaria sanguinalis, humid euphorbia, purslane, chickweed, dodder and the like.
Description
Technical field
The present invention relates to a kind of pesticide water dispersible granules, relate to weed killer herbicide dcpa water dispersible granules and preparation method thereof specifically.
Background technology
The chemical name of compound dcpa is 2,3,5,6 one DCPA.
Its structural formula is:
Dcpa is called for short DCPA, general Chlorthal-dimethyl by name; Commodity are called chlorthaldimethyl, Dacthal or Fatal etc.; English Dimethyl 2,3 by name, 5,6 one tetrachloro-l, 4 one phthalate; Chemistry 2,3,5,6 one tetrachloro-p-phenylene's dioctyl phthalate diformazan vinegar by name; CAs:1861-32-l; Pure product are clear crystal, and fusing point is 154-156 ℃, and is water insoluble, are dissolved in organic solvents such as acetone, benzene,toluene,xylene.Pure product and preparation nature are stable, non-corrosiveness.
Dcpa is a benzoic acid herbicide, inhales transport properties in having, and can be used for the bud pre-treatment, also can carry out the cauline leaf spraying.Be applicable to crops such as corn, soybean, Kidney bean, cucumber, onion, capsicum, strawberry, lettuce, eggplant, turnip, also be applicable to lawn and ornamental plants.Can prevent and kill off annual standing grain herbaceous weed and some broad leaved weed, as green foxtail, lady's-grass, humid euphorbia, kitchen garden, chickweed, dodder etc.
On market, do not find at present any formulation of dcpa.After the advantage of water dispersible granules was entry, disintegration automatically was dispersed into suspension.It is the novel form that grows up on the basis of wetting powder and suspending agent, it has good dispersion, suspensibility height, good stability, characteristics such as easy to use, avoid wetting powder and produced dust, the inconvenience of suspending agent packed and transported, storage easily produce shortcomings such as precipitation, caking, mobile poor, sticking wall.The adhesiveness that is sprayed on the plant is good, and using method is more convenient, and drug effect is relatively good.
Summary of the invention
The purpose of this invention is to provide a kind of dcpa water dispersible granules and preparation method thereof.Dcpa water dispersible granules of the present invention can effectively prevent and kill off in corn, soybean, Kidney bean, cucumber, onion, capsicum, strawberry, lettuce, eggplant, turnip and lawn and the ornamental plants annual standing grain herbaceous weed and some broad leaved weed, as green foxtail, lady's-grass, humid euphorbia, kitchen garden, chickweed, dodder etc.
Its composition of wetting powder provided by the invention is as follows according to weight ratio:
Dcpa 1-95%, wetting dispersing agent 1-5%, dispersant 1-5%, disintegrant 1-3%, binding agent 1-2%, carrier 1-80%.
Adoptable wetting dispersing agent has 600# wetting agent, 700# wetting agent, ABSNa, K12.Dispersant has phenethyl phenol polyethenoxy sodium sulphate, AEO series, NPE, lignosulfonates, NNO, MF, BX etc.Disintegrant has bentonite, PEG, modified starch, mineral salt, white carbon black, silica gel.Binding agent has Sodium Polyacrylate, PEG, sex change PVA, wooden sodium, dextrin, CMC, xanthans.Carrier has kaolin, fine particle calcium carbonate, potter's clay, white carbon black, diatomite.
The preparation method of dcpa water dispersible granules of the present invention at first fully mixes the wetting minute former medicine of agent, dispersant, disintegrant, binding agent, carrier and dcpa in blender according to a certain percentage according to weight ratio, putting into airslide disintegrating mill then pulverizes, secondary mixes then, secondary is pulverized, and sprays water then, extruding, granulation, drying.
Dcpa water dispersible granules provided by the invention has following beneficial effect:
1, good dispersion, suspensibility height, good stability, characteristics such as easy to use have been avoided wetting powder and have been produced dust, the inconvenience of suspending agent packed and transported, storage easily produce precipitation, caking, mobile poor, glue shortcoming such as wall.
2, the adhesiveness that is sprayed on the plant is good, and using method is more convenient, and drug effect is relatively good.
