Abstract
The invention discloses a dispersible oil suspending agent containing florasulam and MCPA-isooctyl. The dispersible oil suspending agent comprises effective active ingredients, namely florasulam and MCPA-isooctyl, a dispersing agent, an emulsifier, a wetting agent, a thickening agent, a stabilizing agent, a defoaming agent, a synergistic agent and plant oil. According to the dispersible oil suspending agent, a scheme of blending two effective active ingredients is adopted, control effect of mixing two effective active ingredients is better than that of a single effective active ingredient, and the dispersible oil suspending agent has a synergistic effect. The prepared dispersible oil suspending agent has the weeding effect obviously better than that of other dosage forms and also has good control effect to various broad leaf weeds in a wheat field, control cost can be reduced, safety to crop is good, and safety requirements to pesticide preparation are met.
Description
Technical field
The present invention relates to a kind of by florasulam and two kinds of active components of the 2 first different monooctyl esters of 4 chlorine, formed dispersible oil-suspending agent, belong to technical field of compounded pesticide.
Background technology
Dispersibling oil-suspending agent is to be dispersion medium with vegetable oil, environmentally friendly, is watered and is sprayed at adhesivity after plant surface, plate-out ability and good penetrability, resistance of rainwater washing against, the lasting period is long, thereby improves agricultural chemicals availability, play synergistic effect, can reduce effective ingredient consumption, cost-saving.
Florasulam, has another name called Mai Shida, English common name Florasulam, chemical name: 2', 6'-bis-fluoro-5-ethyoxyl-8-fluorine [1,2,4] triazoles [1,5-C] pyrimidine-2-sulfonanilide.Florasulam is triazolopyrimidine sulfonamides super-high-efficient weed killer herbicide, is mainly used in preventing and treating wheat paddock broad leaved weed, as clearvers, chickweed, corn gromwell etc. are had to good preventive effect, but general to broadcasting the preventive effects such as ma wormwood artemisia, shepherd's purse, alone slow to weeds drug effect, herbicide is not thorough, has demutation phenomenon.
The different monooctyl ester of 2 first 4 chlorine, English common name MCPA-isooctyl, chemical name: the different monooctyl ester of methoxone.For hormone-type selective herbicide, there is stronger interior suction conductivity, wheat paddock being broadcast to the broad leaved weeds such as ma wormwood artemisia, shepherd's purse has good preventive effect.Shortcoming is the easy demutations of alone weeds, as strengthened consumption, uses, dangerous to wheat.
3.5 hundred million mu of wheat areas are planted throughout the year by China, are only second to paddy rice.Wheat is from after planting being endangered by various broad leaved weeds often to results, chemical control wheat weeds is the most effective means.According to inventor, at the main growing area of wheat, investigated in recent years, find Hebei Province shepherd's purse, broadcast ma wormwood artemisia, the clearvers in Henan, the ox chickweed in Jiangsu, chickweed occur serious, and resistance is serious, above-mentioned florasulam, the different monooctyl ester single dose of 2 first 4 chlorine all can't resolve the problems referred to above, strengthen consumption and also easily produce poisoning, and a kind of herbicidal effect of urgent need invention is good, drug cost is low, the weed killer herbicide of safety nuisance free.
Summary of the invention
The object of the present invention is to provide a kind of component reasonable, synergistic effect is remarkable, and herbicidal effect is good, and drug cost is low, the oil-suspending agent that dispersibles containing florasulam and the different monooctyl ester of 2 first 4 chlorine to crop safety.
Another object of the present invention is to provide the above-mentioned application of oil-suspending agent in control weeds of wheat that dispersible, to be applied in especially weeds of wheat be shepherd's purse, chickweed or broadcast in ma wormwood artemisia.
Implementation procedure of the present invention is as follows:
Containing the oil-suspending agent that dispersibles of florasulam and the different monooctyl ester of 2 first 4 chlorine, its component and weight percentage are as follows:
