Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the Herbicidal combinations of a kind of beflubutamid and diflufenican, be used to prevent and treat 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 ", promptly (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of present 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 valid approach, be that the agricultural chemicals of performance complement obtains best synergistic effect through the proportioning of adjusting different agricultural chemicals.

Embodiment
Below in conjunction with embodiment the present invention is further explained.
Practice example one:
Beflubutamid and diflufenican are mixed to the active determination test report of wheat paddock weeds
Test objective: under the greenhouse pot culture condition, measured beflubutamid and diflufenican and different blended combo thereof and closed herbicidal effect to clearvers; 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: beflubutamid (beflubufamid) 97% former medicine, diflufenican (diflufenican) 98% former medicine, agricultural chemicals Co., Ltd of U.S. nation provides by Shaanxi.
The medicament configuration:
Beflubutamid solution: accurately take by weighing the former medicine of 0.0445g97% beflubutamid,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to beflubutamid 170g (a.i./hm with the 1mLDMF dissolving
2) solution, be diluted to 115g (a.i./hm with clear water again
2), 75g (a.i./hm
2) concentration is subsequent use.
Diflufenican solution: accurately take by weighing the former medicine of 0.0324g98% diflufenican,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to diflufenican 125g (a.i./hm with the 1mLDMF dissolving
2) solution, be diluted to 85g (a.i./hm with clear water again
2), 55g (a.i./hm
2) concentration is subsequent use.
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): 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 2～5 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.Handle back examination material and 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 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 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 beflubutamid is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that diflufenican is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for beflubutamid and two kinds of pharmacy mix of diflufenican to the theoretical value of target weeds fresh weight inhibiting rate; When E is beflubutamid and two kinds of pharmacy mix of diflufenican 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 beflubutamid and diflufenican and the toxicity test result of combination that be mixed thereof to clearvers
Table 1 beflubutamid and diflufenican and the toxicity test result of combination that be mixed thereof to clearvers
Evaluating drug effect: beflubutamid and diflufenican 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 beflubutamid and diflufenican show synergistic effect to clearvers, its E-E with 75+55,75+85,75+125,115+55,115+85,115+125,170+55,170+85, the 170+125 composition that is mixed
