Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains florasulam and fluroxypyr, be used to prevent and treat wheatland and corn field broad leaved weed and nutgrass flatsedge.

3, molecular formula: 4-amino-3,5-two chloro-6-fluoro-pyridines-2-pyridine fluoroacetic acid 1-methyl-heptyl ester.Fluroxypyr is the inner sucting conduction type herbicide after seedling.Very soon by plant absorbing, make sensitive plant the reaction of typical hormone herbicide occur behind the medicine, plant deformity, distortion.In drug resistance plant such as wheat body, the fluorine grass can be combined into conjugates surely and lose toxicity, thereby has selectivity.Temperature does not have influence to the final effect of its weeding, but influences the speed of its drug effect performance.Generally the drug effect performance is slower when temperature is low, stop growing after can making dunsiekte, but dead immediately; Plant was very fast dead after temperature raise.Leaching is not remarkable in soil, and major part is distributed in the 0-10 centimetre of topsoil, under the condition of aerobic, is degraded into non-poisonous materials such as 2-pyridine alcohol very soon in the effect of edaphon, in soil the half life period shorter, can not exert an influence to a following batch broad leaf crop.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
My company is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers with the relevant composite product of fluroxypyr about florasulam.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations that contains florasulam that is used for wheatland and corn field weed control.
Technical scheme of the present invention is:

Embodiment
Below in conjunction with embodiment the present invention is further explained.
Practice example one:
Florasulam and fluroxypyr are mixed to the active determination test report of wheat paddock weeds
Test objective: under the greenhouse pot culture condition, measured florasulam and fluroxypyr and different blended combo thereof and closed herbicidal effect to the target weeds; And estimated its synergy, for the formulation development and the agriculture chemical registration field control effectiveness test of Mixed Pharmacy provides scientific basis.
Supply the examination target: clearvers (Rubiaceae Galium).
Test medicine: florasulam (florasulam) 97% former medicine, fluroxypyr (fluroxypyr) 95% former medicine, agricultural chemicals Co., Ltd of U.S. nation provides by Shaanxi.
The medicament configuration:
Florasulam solution: accurately take by weighing the former medicine of 0.0039g 97% florasulam,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to florasulam 15g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 5g (a.i./hm with clear water again
2), 2g (a.i./hm
2) concentration is subsequent use.
Fluroxypyr solution: accurately take by weighing the former medicine of 0.0482g 95% fluroxypyr,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to fluroxypyr 180g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 100g (a.i./hm with clear water again
2), 60 (a.i./hm
2) concentration is subsequent use.
Blank solution: 0.2mLDMF adds the water of 400mL 0.1%TWEEN80 emulsifier.
Test method: adopt potted plant cauline leaf facture (NY/T 1155.4-2006): the amount of setting soil in the polypots of high 6cm, diameter 9cm; To supply 15～20 sowings of examination target weed seed in polypots; Be placed on cultivation in the greenhouse after covering the thick fine earth of 0.5～1cm, treat that weeds grew to for 2～4 leaf phases and carry out cauline leaf spraying processing, every alms bowl spraying liquid 1mL; Every processing repetition 4 times, and establish the contrast that is treated to that does not contain medicament.Processing is placed in the greenhouse cultivates, the growing state of routine observation target weeds, and be injured symptom and growth inhibition situation of range estimation target behind the 15d, and claim acrial part fresh weight or strain fresh weight, estimate the toxicity action of medicament with form fresh weight inhibiting rate to the target weeds.
Investigation method:
Range estimation target be injured symptom and growth inhibition situation are handled behind the 15d in test, and claim to calculate fresh weight inhibiting rate (%) by the acrial part fresh weight.
The synergy evaluation method:
Estimate weed killer herbicide synergy mode (NY/T 1155.7-2006) according to the Gowing method, its formula is following:
E
0＝X+Y-XY/100
In the formula, X is that florasulam is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that fluroxypyr is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for florasulam and two kinds of pharmacy mix of fluroxypyr to the theoretical value of target weeds fresh weight inhibiting rate; When E is florasulam and two kinds of pharmacy mix of fluroxypyr to the measured value of target weeds fresh weight inhibiting rate.
Evaluation criterion: work as E-E
0Be expressed as synergistic effect at＞10% o'clock, as-10%≤E-E
0Be expressed as summation action, and worked as E-E in≤10% o'clock
0Be expressed as antagonism at＜-10% o'clock.
Table 1 florasulam and fluroxypyr and the toxicity test result of combination that be mixed thereof to clearvers
Table 1 florasulam and fluroxypyr and the toxicity test result of combination that be mixed thereof to clearvers
Evaluating drug effect: florasulam and fluroxypyr and the composition that is mixed thereof are measured the result to the herbicidal effect of clearvers and are seen table 1.It is thus clear that florasulam and fluroxypyr are mixed composition to its E-E of clearvers grass with 2+60,2+100,2+180,5+60,5+100,5+180,15+60,15+100,15+180
0Value shows obvious synergistic effect all greater than 10%.
