Abstract
The invention relates to a field weeding composite of wheat. The field weeding contains clodinafop-propargyl and triclopyr used as effective ingredients and auxiliary components which can be accepted in pesticide, and the weight ratio of clodinafop-propargyl to triclopyr is 1:1 to 1:60. The composite of the two effective ingredients has synergism, and can be used to prevent and kill off various annual grassy weeds and broadleaf weeds and remarkably enhance the weeding effect.
Description
Technical field
The present invention relates to a kind of herbicidal composition, particularly a kind of herbicidal composition for the wheat paddock use.
Background technology
Alkynes oxalic acid commodity are called the top wheat utmost point that claims again, English general Clodinafop-Propargyl by name, chemical constitution is suc as formula shown in (I), alkynes oxalic acid is the fluorine-containing higher low toxicity herbicide of fragrant phenoxy carboxylic acids, be the improved seeds in the weed killer herbicide, efficient, low toxicity, low-residual can effectively be prevented and kill off numerous grassy weeds such as wild oat, amur foxtail, perennial ryegrass etc., alkynes oxalic acid also can be brought into play good drug effect when low temperature, to succession crop safety.
Triclopyr (Triclopyr), chemical constitution is suc as formula shown in (II), belong to pyridine fluoroacetic acid compounds, be selectivity internal-suction type weed killer herbicide, behind weeds leaf and root absorption, conduction complete stool, act on metabolism of nucleic acid, produce excessive nucleic acid, make some structural transformations become meristematic tissue, cause blade, stem and root growth deformity, reserve substance exhausts, the vascular tissue embolism or break, plant is dead gradually.Be mainly used in forest land, uncultivated area, orchard etc., shrub weeds and broad leaved weed are had very strong lethal effect.Can prevent and kill off multiple broad leaved weed, unhelpful forest, shrub, invalid to grassy weed and nutgrass flatsedge.Because wheat has stronger drug resistance to it, also can be used for wheat paddock and prevents and kill off broad leaved weed.
The weeds kind of growing in the wheatland is numerous, and a plurality of Cao Feng of going out are arranged, and the weeds emergence period is long.Common weeds have wild oat, amur foxtail, hard Cao, Wang grass, annual bluegrass, descurainia sophia (l.) webb ex prantl, chickweed, shepherd's purse, clearvers, common vetch, Veronica, Hairy Bittercress etc.Because alkynes oxalic acid is mainly effective to grassy weed, and the greenweed rule is effective to broad-leaved leaf weeds, separately the herbicide effect that uses and effect is all comparatively single and limitation.
Summary of the invention
At above-mentioned situation, the present invention will provide a kind of can prevent and kill off multiple annual gramineous weed in the wheat paddock, can prevent and kill off the highly effective and safe weeding agricultural chemicals of multiple broad leaved weed again.
Field weeding composite of wheat of the present invention, be to be decided to be active ingredient, form jointly that the part by weight of alkynes oxalic acid and Triclopyr is 1: 1 to 1: 60 with acceptable auxiliary element in the agricultural chemicals with alkynes oxalic acid and greenweed, better ratio is 1: 4 to 1: 30, and preferred proportion is 1: 10 to 1: 20.
Acceptable auxiliary element in the said agricultural chemicals, generally can comprise at present in the agricultural chemicals relevant with said active ingredient existing use can not bring into play inert filler all kinds of commonly used and/or the solvent composition that adverse effect is arranged with its generation chemical action or to its drug effect, conventional surfactant composition with effects such as emulsification and/or wetting and/or dispersions, and comprise as anti-caking agent, antifreezing agent, defoamer, bleeding agent, cosolvent, stabilizing agent, tackifier, adding ingredient commonly used in the corresponding agricultural chemicals such as preservative, and can do corresponding selection according to the difference of prepared dosage form.
According to different use needs or applying environment/conditions, the field weeding composite of wheat of the above-mentioned form of the present invention can prepare processing mode by present routine, with acceptable auxiliary element in said two active drug compositions and the agricultural chemicals is raw material, be prepared into multi-form operational corresponding formulation after fully mixing, comprise any in the common pesticides formulations such as wetting powder, water dispersible granules, suspending agent, aqueous emulsion or missible oil.For example:

Existing studies show that, when different herbicidal compositions were used in combination, if then should there be synergistic effect in the activity of weeding after the combination during active when surpassing separate constituent and using.The expectation activity of two kinds of herbicidal compositions under given combination can have formula to calculate (referring to, Colby, SR., Calculating synergistic and antagonistic response of herbicidecombination, Weed 15, pp 20-22,1967):
If at amount of application is under the situation of p kg/ hectare, the loss ratio of weed killer herbicide A is X%; Be that weed killer herbicide B loss ratio is Y% under the situation of q kg/ hectare at amount of application; Be under the situation of p and q kg/ha at amount of application then, the speculative damage rate of weed killer herbicide A and B is E%, wherein E=X+Y-X*Y/100.If actual damage surpasses calculated value, the activity of composition is super adduction, i.e. its demonstration synergy.
Following result of the test shows, after alkynes oxalic acid and two kinds of combination of active principles of Triclopyr, can produce significant synergistic effect in the above-mentioned form Herbicidal combinations of the present invention, can significantly improve herbicidal effect.
Test one: pot experiment
Alkynes oxalic acid and the agent of greenweed order and complex composition are as shown in table 1 to the indoor virulence result of grassy weed and broad leaved weed.Wherein, the caput grass is the 3-4 leaf phase, and clearvers is the 2-3 wheel blade.
Table 1 indoor virulence test result
Test two: field control effectiveness test
Alkynes oxalic acid and the agent of greenweed order and complex composition are as shown in table 2 in the field control effectiveness test result who prevents and kill off the wheat paddock weeds.Test is in the wheat 4-5 leaf phase, weeds 3-5 leaf phase, the fresh weight preventive effect result of investigation in 45 days after the dispenser.Composition medicine of the present invention is the preparation of the foregoing description 11 in the test.
Table 2 field weeding test of pesticide effectiveness result
The result of the test of table 2 shows by alkynes oxalic acid and two kinds of composite present compositions of active ingredient of Triclopyr, to have the wider grass that kills and compose, and can significantly improve preventive effect, and no antagonism is to wheat safety.
