Abstract
The invention relates to a weeding composition containing halosulfuron-methyl and quinclorac as well as fluroxypyr. The effective components of the weeding composition are halosulfuron-methyl and quinclorac as well as fluroxypyr, and the weight part ratio of halosulfuron-methyl, quinclorac and fluroxypyr is (1-10):(1-50):(1-20). The weeding composition has a synergistic effect, can be used for preventing and removing grassy weeds, broadleaf weeds and cyperaceous weeds in wheat fields, corn fields, paddy fields, sugarcane fields and sorghum fields, is remarkably superior to a individual weedicide separately used or a combination of two weedicides in effect, expands a weeding spectrum, reduces the pesticide consumption, alleviates the environmental pollution and delays the pesticide resistance of the weeds.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and application thereof, be specifically the Herbicidal combinations effectively become with halosulfuronmethyl, dichloro quinolinic acid and fluroxypyr, be applied to and prevent and kill off wheat paddock, corn field, paddy field, sugarcane field, the grassy weed of sorghum field, broad leaved weed and sedge weed.
Background technology
Halosulfuronmethyl (halosulfuron-methyl): belong to sulfonylurea weed killer herbicide, be mainly used in broad leaved weed and the sedge weed of preventing and kill off the ground such as wheat, corn, paddy rice, sugarcane, lawn, as storehouse ear, Datura, artemisiifolia, Amaranthus retroflexus, flowerofanhour root or herb, knotweed, kitchen garden, black nightshade, Cassia tora, lead a cow, the rhizome of nutgrass flatsedge etc., because it can rapid metabolization be innocuous substance in crop, therefore to crop safety, can use with Miao Houjun before seedling.
Dichloro quinolinic acid (quinclorac): belong to hormone-type quinoline carboxylic acid weed killer herbicide, this compound can be absorbed by seed, root and the leaf portion of sprouting, to barnyard grass, there is special efficacy, effectively can also prevent and kill off Monochoria vaginalis, Chinese celery etc., poor to the control efficiency of sedge weed.
Fluroxypyr (fluroxypyr): belong to cauline leaf process weed killer herbicide after inner sucting conduction type seedling, absorbed by weeds very soon after dispenser, make sensitive plant occur the reaction of classical hormones class weed killer herbicide and be transmitted to each position of complete stool, make plant deformity, distortion, finally dead.Be applicable to the ground such as wheat, barley, corn, grape, orchard, pasture, forest land, lawn and prevent and kill off broad leaved weed, as clearvers, volume stem knotweed, kitchen garden, black nightshade, field bindweed, knotweed, amaranth etc., invalid to grassy weed.
Chemical method weeding is agriculturally one of Main Means controlling weeds in field.In recent years, because the large area of some weed killer herbicide kinds is used alone, many weeds have been caused to create pesticide resistance; Meanwhile, because grass when weeds in field occurs is complicated, of a great variety mutually, as grassy weed, sedge weed and broad leaved weed etc. occur simultaneously, the weed killer herbicide of single variety uses and cannot effectively solve the problem, and all can show defect in a certain respect.
By the screening of different weed killer herbicide kind compounded formula, filter out rational formula, effectively can improve the actual control efficiency to weeds, expand herbicide spectrum, reduce dosage, reduce costs, alleviate the pollution to environment, delaying the generation of herbicide resistance, is the important means of the agriculturally weeds comprehensive regulation.
The present inventor uses the ternary built of halosulfuronmethyl, dichloro quinolinic acid and fluroxypyr and conducts in-depth research, a large amount of formula indoors screening and field medicine effect test basis on, find that halosulfuronmethyl, dichloro quinolinic acid and fluroxypyr carry out ternary built, within the scope of certain compound proportion, obvious synergistic function is all shown to the grassy weed of wheat paddock, corn field, paddy field, sugarcane field, sorghum field, broad leaved weed and sedge weed, after further study, the present invention is completed.
Not yet find the relevant report of halosulfuronmethyl, dichloro quinolinic acid and fluroxypyr ternary built at present.
Summary of the invention

2, in formula, X be halosulfuronmethyl alone with certain dosage time be the percentage of contrast to the fresh weight inhibition of target weeds; Y be dichloro quinolinic acid alone with certain dosage time be the percentage of contrast to the fresh weight inhibition of target weeds; Z be fluroxypyr alone with certain dosage time be the percentage of contrast to the fresh weight inhibition of target weeds; E
0for during halosulfuronmethyl, dichloro quinolinic acid and fluroxypyr three kinds of pharmacy mix to target weeds fresh weight inhibition being the theoretical value of the percentage contrasted; Be the measured value of the percentage of contrast to target weeds fresh weight inhibition when E is halosulfuronmethyl, dichloro quinolinic acid and fluroxypyr three kinds of pharmacy mix.
Evaluation criterion: work as E
0synergistic effect is expressed as, as-10%≤E during-E>10%
0be expressed as summation action during-E≤10%, work as E
0antagonism is expressed as during-E<-10%.
As can be seen from the Toxicity Determination result of table 1, table 2 and table 3, halosulfuronmethyl, dichloro quinolinic acid and fluroxypyr mixture respectively process the E to kitchen garden, barnyard grass and the rhizome of nutgrass flatsedge
0-E (%) value is all greater than 10%, illustrates that three is composite and all has synergistic function to kitchen garden, barnyard grass and the rhizome of nutgrass flatsedge.As can be seen here, halosulfuronmethyl, dichloro quinolinic acid and fluroxypyr Ternary have reasonability and feasibility.
Table 1, each chemicals treatment are to the Toxicity Determination result of kitchen garden.
Table 2, each chemicals treatment are to the Toxicity Determination result of barnyard grass
Table 3, each chemicals treatment are to the Toxicity Determination result of the rhizome of nutgrass flatsedge
Assays Example 2: field control effectiveness test.
Experimental field select kitchen garden, barnyard grass and the rhizome of nutgrass flatsedge that more corn field occurs to carry out.8 process are established in test altogether, often 3 repetitions are established in process, process 1 is 22% halosulfuronmethyl dichloro quinolinic acid fluroxypyr oil-suspending agent (example of formulations 3), process 2 is 17% halosulfuronmethyl dichloro quinolinic acid oil-suspending agent (2:15), process 3 is 7% halosulfuronmethyl fluroxypyr oil-suspending agent (2:5), process 4 is 20% dichloro quinolinic acid fluroxypyr oil-suspending agent (15:5), process 5 is 75% halosulfuronmethyl water dispersible granules, process 6 is 25% Dichloroquinolinic acid suspending agent, process 7 is 20% fluroxypyr missible oil, process 8 is contrast (not dispenser not weeding), within after medicine 30 days, add up each process number of weeds amount and calculate preventive effect.
The field control effectiveness test result of table 4, each chemicals treatment Control Weeds in Maize Field
As can be seen from the field test results of table 4, when within after medicine 30 days, 22% halosulfuronmethyl dichloro quinolinic acid fluroxypyr oil-suspending agent (example of formulations 3) usage amount is 325-400g.a.i./ha, each single dose is all obviously higher than to the preventive effect of the kitchen garden of corn field, barnyard grass and the rhizome of nutgrass flatsedge or binary built uses, in pilot survey process, does not find that it produces poisoning to corn simultaneously.As can be seen here, said composition is worth applying in agricultural production.
