Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the Herbicidal combinations of a kind of beflubutamid and azoles quinoline grass ester, be used to preventing and treating the common weeds of wheatland.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", namely (1) is safe, and this not only requires toxicity low, residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of current Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of effective approach, the agricultural chemicals that is performance complement by the proportioning of adjusting different agricultural chemicals obtains best synergistic effect.

2) solution, then be diluted to 115g (a.i./hm with clear water
2), 75g (a.i./hm
2) concentration is standby.
Azoles quinoline grass ester solution: accurately take the former medicine of 0.01204g95% azoles quinoline grass ester, dissolve with 1mLDMF, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to azoles quinoline grass ester 45g (a.i./hm
2) solution, then be diluted to 35g (a.i./hm with clear water
2), 20g (a.i./hm
2) concentration is standby.
Blank solution: 1mLDMF adds the water of 400mL 0.1%TWEEN80 emulsifier.
Test method: adopt potted plant cauline leaf facture (NY/T 1155.4-2006): at the in-built quantitative soil of the polypots of high 6cm, diameter 9cm, will be for 15～20 sowings of examination target weed seed in polypots, after covering the fine earth that 0.5～1cm is thick, be placed on cultivation in greenhouse, treat that weeds grew to for 2～5 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.After processing, the examination material is placed in the greenhouse in and cultivates, the growing state of routine observation target weeds, and be injured symptom and growth inhibition situation of range estimation target after 15d, and claim acrial part fresh weight or strain fresh weight, 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 processed after 15d in test, and claim to calculate fresh weight inhibiting rate (%) by the acrial part fresh weight.
The synergy evaluation method:
According to the Gowing method, estimate weed killer herbicide mode of application (NY/T 1155.7-2006), its formula is as follows:
E
0＝X+Y-XY/100
In formula, X is beflubutamid fresh weight inhibiting rate to target weeds when alone with certain dosage; Y is azoles quinoline grass ester fresh weight inhibiting rate to target weeds when alone with certain dosage; E
0During for two kinds of pharmacy mix of beflubutamid 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 beflubutamid and azoles quinoline grass ester to the measured value of target weeds fresh weight inhibiting rate.
Evaluation criterion: work as E-E
0In the time of>10%, be expressed as synergistic effect, as-10%≤E-E
0In the time of≤10%, be expressed as summation action, work as E-E
0In the time of<-10%, be expressed as antagonism.
