Abstract
The herbicide composition is compounded with fenoxaprop-P-ethyl and one or more of sulfony urea herbicides tribenuron-methyl, thifensulfuron-methyl and bensulfuron-methyl. In the composition, the weight ratio between fenoxaprop-P-ethyl and sulfony urea herbicides is 1 to 0.1-2. Fenoxaprop-P-ethyl has high killing activity to monocotylous weed and the sulfony urea herbicides have excellent dicotyledonous weed preventing effect, so that the composition can prevent and kill both monocotylous and dicotyledonous weeds in wheat field effectively and has excellent synergetic effect.
Description
(1), technical field
The present invention relates to a kind of agrochemical composition, exactly is by the herbicidal composition of fenoxapropPethyl with the composite control wheat paddock weeds of sulfonylurea herbicide.
(2), background technology
Wheat is one of China's five macrospecies plants, and cultivated area is about 2,750 ten thousand hectares throughout the year, is only second to rice area in China.The wheat paddock weeds rate of being injured is about 75%, and the underproduction about 15% thus, but the highest underproduction is a key factor that influences wheat quality and output more than 80%.The wheat paddock main weeds has monocotyledon weed such as amur foxtail, hard grass, deceive grass etc. and broadleaf weed such as chickweed, clearvers, corn gromwell, with fiber crops etc.In China, the weed killer herbicide of having prevented and kill off the wheat paddock weeds since the normal phase has that isoproturon, oatax, triallate, chlortoluron, metsulfuron-methyl, green sulphur are grand, superstar etc., the grass that kills that has in these kinds is composed narrow, can only prevent and kill off part unifacial leaf or broadleaf weed, as isoproturon, oatax, triallate, superstar etc.: the kind that has residual life in soil, is very long, easily a following batch sensitive crop is impacted, some kind is disabled or limit the use of,, chlortoluron grand as metsulfuron-methyl, green sulphur etc.
In recent years, hard grass and not careless the rising rapidly at the many Mai Qu of China are caused harm, and especially seriously take place on Su Wan and other places, the peasant is produced cause very big threat.Some weed killer herbicides commonly used are difficult to prevent and kill off these type of weeds in the market, and fenoxapropPethyl is tested and extensive application proves hard grass and deceives grass highly active weed killer herbicide is arranged.Sulfonylurea herbicide tribenuron-methyl, thifensulfuron methyl and bensulfuron-methyl are class super-high-efficient selectivity foliar herbicides, can prevent and kill off multiple broadleaf weed, to wheat safety.The peasant often will use unifacial leaf weed killer herbicide and dicotyledonous weed killer herbicide respectively at twice when using weed killer herbicide, perhaps mix existing usefulness with both are existing, and not only spraying times is many, dispenser trouble, and cost height, improper use in addition cause poisoning or preventive effect not good.The disclosed herbicidal composition of CN 1152395A is composite by Acetochlor and symetryne, is mainly used in peanut, soybean, rape, corn and agent for removing grass in paddy field.
(3), summary of the invention
Since thinking of the present invention is to exist single, double cotyledon weeds in the wheatland simultaneously, its control needs weed killer herbicide separately again, so why not with two class mixture of herbicides, so both can improve preventive effect, makes things convenient for the peasant to use again.The present invention under this thinking instructs, by test, filters out the fenoxapropPethyl that multiple monocotyledon weed is had excellent preventive effect just

3Between relative quantity can be any.Effective ingredient A has excellent preventive effect to multiple monocotyledon weed, to the hard grass of malignant weed, not careless active high, and effective ingredient B is remarkable to the broadleaf weed effect, and what the present invention combined both kills the grass spectrum, can disposablely prevent and kill off the single, double cotyledon weeds of wheat paddock after composite.The effective ingredient A of the present invention's selection and B are wheat paddock weed killer herbicides efficient, low-residual, and composite back product is tested and used through a large amount of, shows Wheat Production is had no effect, to second stubble crop safety.Herbicidal composition provided by the present invention is a kind of wheat paddock highy potent herbicide, Shenyang Chemical Engineering Inst and Agricultural University Of Nanjing show that by indoor bioassay smart oxazole standing grain spirit grass is addition and synergistic effect with the composite back of sulfonylurea herbicide tribenuron-methyl, thifensulfuron methyl or bensulfuron-methyl to the activity of weeding that tries material.Composite dose herbicide effect is the growing point that absorbs and be transmitted to phyllopodium, internode meristematic tissue and root by the weeds cauline leaf, and the weed growth of being injured is suppressed, and stops its biosynthesis, makes weeds withered gradually.It is prevented and kill off object and comprises amur foxtail, wild oat, hard grass, deceives multiple single, double cotyledon weeds such as grass, ox chickweed, clearvers, corn gromwell, shepherd's purse.To wheat and succession crop safety.Have characteristics such as dispenser convenience, broad weed-killing spectrum, safety height.
The joint toxicity measuring test of carrying out in Agricultural University Of Nanjing and Shenyang Chemical Engineering Inst shows, the co-toxicity coefficient of the proportioning of effective ingredient A and B (1: 0.1,1: 0.2,1: 0.25,1: 0.3,1: 0.4,1: 0.5,1: 1,1: 2) is all greater than 100%, to the co-toxicity coefficient of wild oat between 256～674%, the co-toxicity coefficient of benbie all more than 100%, is shown extremely strong synergistic effect.
