Abstract
The invention relates to a weeding composition containing florasulam and pinoxaden. The composition is mainly characterized by containing 1 to 60 percent of florasulam serving as an active ingredient, 1 to 60 percent of pinoxaden, auxiliary agent and other excipient; and the weeding composition can be prepared into wettable powder, water dispersible granules, suspending agent, emulsion, micro emulsion, emulsion in water or the like. The weeding composition is used for preventing and controlling broadleaf weed and gramineous weed in wheat fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains florasulam and azoles quinoline grass ester, be used to prevent and treat cornfield gramineae weed and broad leaved weed.
Background technology
Nineteen fifty-five has the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch, after, along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, is recognized extensively that to do be one of important measures of rationally using of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained bigger progress.

2) solution, be diluted to 50g (a.i./hm with clear water again
2), 25g (a.i./hm
2) concentration is standby.
Blank solution: 0.2mLDMF adds the water of 80mL 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, will be in polypots for 15～20 sowings of examination target weed seed, 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 repeats 4 times, and establishes the contrast that is treated to that does not contain medicament.Handle the back examination and just place in the greenhouse in and cultivate, the growing state of routine observation target weeds, be injured symptom and growth inhibition situation of range estimation target behind the 15d, and title acrial part fresh weight or strain fresh weight are with the toxicity action of form fresh weight inhibiting rate evaluation medicament 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 as follows:
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 azoles quinoline grass ester is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for two kinds of pharmacy mix of florasulam and azoles quinoline grass ester to the theoretical value of target weeds fresh weight inhibiting rate; When E is two kinds of pharmacy mix of florasulam and azoles quinoline grass ester 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.
