Abstract
The composition of a compounded weedicide suspending agent for paddy field is composed of (wt%) 10.0-50.0% quinclorac, 0.5-5.0% of pyrazosulfuron-ethyl, 1.0-15.0% of adjuvant and water to make up 100%. Said invention can prevent and kill gramineous and broad-leaf weeds in rice field, and applicable to various methods of cultivation, such as throw-planting of rice seedling, transplanting field and direct sowing field, and its weeding effect is above 90%, it can effectively control weeds for above 45 days, and can obviously raise yield of rice by 19.8%, and possesses the effects of regulating rice growth and development.
Description
The present invention relates to a kind of composition of paddy field compound herbicide suspending agent of killing weeds in rice field.
Before invention is made, the herbicides for use in paddy of selling on the market is a lot, all be pulvis and missible oil etc., and majority is based on butachlor, or add the weed killer herbicide that other mixtures are made, as Chinese patent 91105612.2 " a kind of herbicidal composition of killing weeds in rice field ", be basic medicine with butachlor exactly, add the 2.4-D butyl ester, emulsifier, the design of mixture of solvent etc. is processed into missible oil, though this missible oil has certain effect to removing grassy weed and broad leaved weeds, but to be mixed into missible oil with solvent (benzene) with emulsifier, in process of production, solvent benzol is harmful, contaminated environment, and pulvis weed killer herbicide bad dispersibility influences herbicidal effect.
Purpose of the present invention is exactly the herbicidal composition that a kind of efficient aqueous suspension agent of killing weeds in rice field will be provided, and can not only prevent and kill off grassy weed and other broad leaved weed effectively, and water is cooked solvent, the minimizing environmental pollution.The aqueous suspension agent of making, good dispersion, safe, the seedling band soil rice transplanting that cooperation China is promoting and the wet rice cultivation method in live field, to alleviate rural labor intensity and to increase output, the weed killer herbicide of this safe of low pollution is the direction of China's Future Development.
Technical solution of the present invention is: selected paddy rice fool proof, and remove barnyard grass grass obvious results dichloro quinolinic acid is main, add that pyrazosulfuron is mixed to having efficiently except that broadleaved herb, nutgrass flatsedge etc., add that auxiliary agent becomes most of with water through attrition process and is the aqueous suspension agent of 3-5 μ particle diameter, its composition is: (percentage by weight)
Dichloro quinolinic acid 10.0-50.0%
Pyrazosulfuron 0.5-5.0%
Auxiliary agent 1.0-15.0%
Solvent (water) is mended to 100%
Auxiliary agent is mixtures such as dodecyl benzene sulfonate, styryl phenyl APEO and active carbon white, ethylene glycol, isooctanol in the above-described composition.
Through the laboratory animal toxicological test, per os is taken in acute LD about composition of the present invention
50Value is greater than 5100mg/kg, and is through the test of skin contamination property, acute through skin LD
50Value belongs to low toxicity level greater than 2100mg/kg, acute skin irritation test, and mean scores is 0, nonirritant.Acute eye irritation test, average index 2.5 (48h) minimal irritation.
Herbicidal suspension agent synergy test (seeing Table 1,2,3).
The method that imposes on the rice field with aqueous suspension agent composition of the present invention is behind the rice transplanting ten days, by every mu of active component (ai) 6-12 gram convert spray behind 50 kilograms in the water or with spread fertilizer over the fields after urea mixes, there is water layer in the rice field during dispenser, and after dispenser, keep seven days shoaling layers, just can obtain the herbicidal effect more than 90%, and can effectively control crop smothering more than 45 days, can significantly improve rice yield, the highest volume increase 19.8%.
Advantage of the present invention is to prevent and kill off grassy weed and broad leaved weeds effective and safe, be applicable to the various methods of cultivation such as the seedling rice transplanting of paddy rice, live field and transplant field, overcome other weed killer herbicide and can only be used in shortcoming on certain methods of cultivation, for example: missible oil will be used benzene solvent, contaminated environment, harmful.Pulvis bad dispersibility for another example.This product is solvent with water, processing back dispersive property excellence, so be highly effective and safe, to the person poultry harmless, broad weed-killing spectrum also has good control efficiency to 5-6 leaf age barnyard grass grass, and can play regulating action to rice growth.This product production technology is simple, safety, cost are low, effective, is that a kind of to prevent and kill off multiple weeds efficient and to the fine herbicide of rice shoot safety.
