Abstract
The invention relates to a herbicidal composition containing isoxaflutole and fluroxypyr. The composition is mainly characterized by containing the active components of: 1-70% of the isoxaflutole and 1-70% of the fluroxypyr, as well as auxiliaries and other excipients, wherein the composition can be prepared into a wettable powder, a water dispersible powder, an oil suspending agent, a suspending agent, a micro emulsion, an emulsion in water and the like. The herbicidal composition is used for preventing and controlling broadleaf weeds and gramineous weeds in oil fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the Herbicidal combinations of a kind of Han isoxazole humulone and fluroxypyr, be used for control cornfield gramineae weed and broad leaved weed.
Background technology
Nineteen fifty-five has the people to report that Amrol can increase dalapon to the effect of the preventing and kill off beginning of 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 75g (a.i./hm with clear water again
2), 45g (a.i./hm
2), 15g (a.i./hm
2) concentration is standby.
Fluroxypyr solution: accurately take by weighing the former medicine of 0.2810g 95% fluroxypyr, with the 0.2mLDMF dissolving, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to fluroxypyr 210g (a.i./hm
2) solution, be diluted to 160g (a.i./hm with clear water again
2), 110g (a.i./hm
2), 60g (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 for 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 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 Wei isoxazole humulone 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
0When Wei isoxazole humulone and two kinds of pharmacy mix of fluroxypyr to the theoretical value of target weeds fresh weight inhibiting rate; When E Wei isoxazole humulone 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 isoxazole humulone and fluroxypyr and the toxicity test result of combination to kitchen garden that be mixed thereof
