Abstract
The invention relates to a cornfield weeding composition comprising the effective components of carfentrazone-ethyl and rimsulfuron, wherein the proportion of the quality parts of the carfentrazone-ethyl and the rimsulfuron is 30:1-1:50. The carfentrazone-ethyl and the rimsulfuron are compounded, have an obvious synergistic action and expand prevention and treatment spectra. The composition can beused for preventing and removing various kinds of weed in cornfields.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations, be specially azoles humulone and the composite Herbicidal combinations of another active component with synergistic effect, and the application on corn field weed is prevented and kill off.
Background technology
Farmland weed and the crops liquid manure that wins honour for is again the important place of hiding, lodge of damage by disease and insect, and annual production to crops caused very big loss.The most general, the most economical method of control farmland weed employing is a chemical control at present, removes the mixture of herbicides of composing by the different mechanisms of action or different preventing, can improve preventive effect, enlarge and prevent and kill off spectrum.
The spirit of going out soon of azoles humulone trade name, English common name Carfentrazone-ethyl, chemical name is ethyl-2-chloro-3-(2-chloro-5-(4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxygen-1H-1,2,4 triazol-1-yls)-and the 4-fluorophenyl) ethyl propionate), belong to the triazolineone systemic herbicide.Be applicable to that wheat paddock, corn field and paddy field prevent and kill off broad leaved weed and nutgrass flatsedge, the weeds that sulfonylurea herbicide produced resistance have very high activity.Its mechanism of action is for the protoporphyrin oxidase causes that cell membrane destroys in the chlorophyll biosynthetic process by suppressing, and makes blade withered, dead rapidly.It is fast to be characterized in killing careless speed, and medication 3-4 days weeds are all dead under suitable temperature.But its weeding scope is narrower, the lasting period short.
Rimsulfuron claims rimsulfuron 25 again, and rimsulfuron is acetolactate synthestase (ALS) inhibitor, promptly by suppressing the acetolactate synthestase of plant, stops the biosynthesis of branched-chain amino acid, thereby suppresses cell division.Its weeding characteristics are to can be used for preventing and kill off most of annual or perennial grassy weeds of corn field and part broad leaved weed.Because rimsulfuron metabolism in corn and susceptible weeds is that the speed of non-activity metabolite is variant, the half life period of rimsulfuron in maize leaves be 6H only, and that the half life period in weeds such as mouse tail amur foxtail, Aleppo grass will be grown is many, so it is as safe as a house that rimsulfuron uses at corn field, and second stubble crop there is not harmful effect.Its weeding shortcoming is relatively poor to corn field broad leaved weed effect.
Summary of the invention
The purpose of this invention is to provide a kind of cornfield weeding composition that is used for, have the activity of weeding height, can prevent and kill off corn field weed effectively, comprehensively, the active component of this Herbicidal combinations is azoles humulone and rimsulfuron.
Technical scheme
A kind of Herbicidal combinations is characterized in that: active ingredient is azoles humulone and rimsulfuron, and the mass ratio of azoles humulone and rimsulfuron is 30: 1-1: 50.
Described Herbicidal combinations, wherein the active ingredient total content is 5%-80%.
Described Herbicidal combinations is characterized in that: active ingredient adds auxiliary agent and excipients is made wetting powder, water dispersible granules, suspending agent and oil-suspending agent according to production technology well known by persons skilled in the art.
As a kind of improvement of Herbicidal combinations of the present invention, wherein active ingredient azoles humulone and rimsulfuron preferable quality ratio are 10: 1-1: 20.
Beneficial effect of the present invention is: 1. the present invention passes through the composite of azoles humulone and rimsulfuron, has significant synergies, and reduces the consumption of active ingredient, reduces cost, and reduces environmental pollution; 2. overcome each single agent simultaneously and on cornfield weeding, prevent and treat the narrow shortcoming of spectrum, enlarge herbicidal spectrum, improve quick-acting, prolong lasting effect.

(2) the indoor determination of activity and the field control effectiveness test of the present composition
1, synergy biologicall test
For trying weeds: be experimental field interior grassy weed-lady's-grass (Digitaria sanguinalis (Linn.) Scop) and the broad leaved weed-Amaranthus retroflexus of gathering (Amaranthusretroffexus L.) of the general letter of Shenzhen promise farmingization Co., Ltd
Test medicine: different proportioning medicaments in the azoles humulone, rimsulfuron and the embodiment of the invention.
Assay method: indoor pot method.Handle in lady's-grass tri-leaf period, two leaf period cauline leafs sprayings of Amaranthus retroflexus; 750 liters/hectare of the water yields are converted in spraying, and every processing repeats for five times, measure survival weeds fresh weight in 15 days behind the spray medicine, adopt 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:
The composite joint toxicity measuring of table 1 azoles humulone and rimsulfuron different proportion to lady's-grass, Amaranthus retroflexus
The result of azoles humulone and the indoor joint toxicity measuring of rimsulfuron shows that azoles humulone and rimsulfuron are composite, 40: 1-1: in 50 scopes grassy weed lady's-grass and broad leaved weed Amaranthus retroflexus are all had synergistic effect.
2, field trial
In May, 2008, at corn four leaves, weeds were in the 2-3 leaf phase in the general letter of promise farmingization Co., Ltd proving ground, and the main weeds kind is lady's-grass, Amaranthus retroflexus, acalypha copperleaf, the rhizome of nutgrass flatsedge, kitchen garden etc.Compound drug with the embodiment of the invention carries out field spray, does contrast, sub-district area 5m with 40% azoles humulone water dispersible granules (U.S. Fu Meishi company), the single agent of 25% rimsulfuron water dispersible granules (du pont company)
2, repeat for 3 times, carried out effect research behind the medicine in 15 days.Adopt accidental sampling during investigation, the sampling area is 1m
2, monocotyledon weed and broadleaf weed survival volume fresh weight in the Classification Count sampling area.Result of the test is as follows:
The field efficacy that table 2 azoles humulone and rimsulfuron are composite
