Abstract
The invention relates to a weeding composition comprising flumetsulam and another active component, wherein another active component is nicosulfuron or rimsulfuron. The mass ratio of the flumetsulam and another active component is 40:1-1:40. The flumetsulam is compounded with the nicosulfuron or the rimsulfuron, has a synergistic action to the prevention and the treatment of weed in cornfields, and can effectively prevent and remove broadleaf weed and gramineous weed, lower the application cost and enhance the safety of lower-stubble crops. The composition is used for weeding in the cornfieldsand is especially suitable for weeding before seedlings after planting in the cornfields.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations, be specially a kind of Herbicidal combinations that contains Flumetsulam and another active component, and the application of said composition on cornfield weeding.
Background technology
Corn field herbicide is mainly based on closed soil, and herbicide after seedling is less.Corn field herbicide major part now commonly used is better to the preventive effect of broad leaved weed, and lower to the preventive effect of grassy weed, for example atrazine etc.; Also there is a spot of weed killer herbicide better, and poor slightly, for example nicosulfuron and rimsulfuron to the control efficiency of broad leaved weed to the control efficiency of grassy weed.
Flumetsulam (Flumetsulam), be Flumetsulam again, chemical name is: 2 ', 6 '-two fluoro-5-methyl (1,2,4)-triazol (1,5-a) pyrimidine-2-sulfonanilide is interior suction conductivity weed killer herbicide, by root system and the blade absorption of weeds, xylem and phloem conduction accumulate in the weeds meristematic tissue.By suppressing acetolactate synthestase in the weeds body, protein synthesis is obstructed, weed growth stops, and finally causes death.Broad weed-killing spectrum, better to most of broad leaved weed preventive effects.Be applicable to crops such as corn, soybean, wheat.Can effectively prevent and kill off multiple wealthy weeds such as lamb's-quarters, Amaranthus retroflexus, recessed amaranth, acalypha copperleaf, clearvers, common vetch.Soluble in water, than under the arid situation, also can reach herbicidal effect at soil.Shortcoming: it is relatively poor to prevent and kill off the grassy weed effect, during large usage quantity, some succession crops is had residual poisoning influence.
Nicosulfuron (Nicosulfuron), chemical name 1-(4,6-dimethoxypyridin-2-yl)-3-(3-dimethylamino formylpyridine-2-base sulphonyl) urea, it is systemic herbicide, can be absorbed by weeds cauline leaf and root, in plant corpus, conduct, cause susceptible weeds growth retardation, cauline leaf chlorisis, withered gradually, but under the lower situation of temperature, some perennial weed is needed the long time.This medical instrument has the preceding activity of weeding of bud, but active in low behind the bud.
Rimsulfuron (Rimsulfuron); chemical name: N-(((4; 6-dimethoxy-2-pyrimidine radicals) carbonyl amino))-3-(ethylsulfonyl)-2-pyridine sulfonamide; be acetolactate synthestase (ALS) inhibitor; by suppressing the acetolactate synthestase of plant; stop the biosynthesis of branched-chain amino acid, thereby suppress cell division, to corn safety.Can prevent and kill off most of annual and perennial grassy weeds of corn field and part broad leaved weed.During use, succession crop is had no adverse effects, but sweet corn, pop corn, glutinous corn and seed farm should not use.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations, said composition active ingredient is Flumetsulam and another herbicidal active component, and the application of said composition in corn field weed is prevented and kill off.
The present invention is achieved through the following technical solutions:
A kind of Herbicidal combinations is characterized in that: active ingredient is Flumetsulam and another active component, and the mass ratio of Flumetsulam and another active component is 40: 1-1: 40, and described another active component is any one in nicosulfuron or the rimsulfuron.
Described Herbicidal combinations is characterized in that active ingredient adds auxiliary agent and excipients is made formulation, especially suspending agent, oil-suspending agent, wetting powder, the water dispersible granules that agricultural upward is suitable for according to production technology well known by persons skilled in the art.In described Herbicidal combinations preparation, the active ingredient total content is 5%-90%.
Described Herbicidal combinations is characterized in that being used for cornfield weeding, is particularly useful for corn field and broadcasts the preceding weeding of back seedling.
Useful achievement of the present invention is: 1. two kinds of compositions reduce effective ingredient consumption in conjunction with having obvious synergistic effect in the composition, improve herbicidal effect; 2. enlarge and prevent and kill off spectrum, composition has good herbicidal effect to corn field broad leaved weed and grassy weed.3. based on the synergy of compound drug, reduce the dosage of Flumetsulam, improve the safety of composition, reduce cost, be of value to ecology and environmental protection second stubble crop.

(2) joint toxicity measuring of the present composition and field control effectiveness test
1, joint toxicity measuring
Test site: test is on Ya'an, Sichuan Province Sichuan Agricultural University teaching test farm.
Subjects: corn field of summer monocotyledon weed-annual bluegrass section knotgrass lady's-grass (Digitariasanguinalis (L.) Scop.) and broadleaf weed-Euphorbiaceae Acalypha plant iron three-coloured amaranth (Acalyphaaustralis L.).
Test medicine: Flumetsulam, nicosulfuron, rimsulfuron and the embodiment of the invention.
Assay method: field trial method.Handle in lady's-grass 3-4 leaf phase, the spraying of acalypha copperleaf cauline leaf in seedling stage; 750 liters/hectare of the water yields are converted in spraying, measure the weeds fresh weight of living in 10 days after the dispenser, and every processing repeats for five times, adopts the Colby method to judge the synergy type.
Colby law theory preventive effect computing formula is:
E
0＝XY/100
E in the formula
0Be single agent A and the B theoretical preventive effect after using with; X is that weed killer herbicide A weeds weight under certain dosage is the percentage of contrast weeds weight; Y is that weed killer herbicide B weeds weight under certain dosage is the percentage of contrast weeds weight; If being A, B, E uses the percentage of the weeds weight of back actual measurement with for contrast weeds weight.If E is significantly less than E
0, then be synergistic effect; E and E
0, approaching, then be summation action; E is obviously greater than E
0, then be antagonism.
Result of the test:
Table 1 Flumetsulam and nicosulfuron are composite to lady's-grass, acalypha copperleaf joint toxicity measuring
The test effect of Flumetsulam and the composite joint toxicity measuring of nicosulfuron shows that Flumetsulam and nicosulfuron are composite, 40: 1-1: in 40 the ratio range, have synergistic effect.
Table 2 Flumetsulam and rimsulfuron are composite to lady's-grass, acalypha copperleaf joint toxicity measuring
The result of the test of azoles ether sulphur grass amine and rimsulfuron joint toxicity measuring shows that Flumetsulam and rimsulfuron are composite, 40: 1-1: in 40 the ratio range, have synergistic effect.
2, field trial
In March, 2008, to the rock town, at corn four leaves, weeds were in the 2-4 leaf phase in the Ya'an, Sichuan Province, sprayed sub-district area 10m respectively with above-mentioned test medicament and contrast agents
2, repeat for three times, carried out effect research behind the medicine in 10 days.Adopt accidental sampling during investigation, the sampling area is 1m
2, investigation survival strain number, result of the test is as follows:
