Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of grand Herbicidal combinations with the azoles humulone of ethoxy sulphur that contains, be used to prevent and treat paddy rice and wheat paddock weeds.
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, make the agricultural chemicals of performance complement obtain 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:
Ethoxy sulphur is grand to be mixed to the active determination test report of paddy field weed with the azoles humulone
Test objective: measured under the greenhouse pot culture condition that ethoxy sulphur is grand to close the herbicidal effect to nutgrass flatsedge with azoles humulone and different blended combo thereof, 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: nutgrass flatsedge (CyperusrotundusL.).
Test medicine: ethoxy sulphur swells (diflufenican) 95% former medicine, azoles humulone (carfentrazone-ethyl) 90% former medicine, and agricultural chemicals Co., Ltd of U.S. nation provides by Shaanxi.
The medicament configuration:
Ethoxy sulphur swells solution: accurately take by weighing the grand former medicine of 0.0201g 95% ethoxy sulphur; With the dissolving of 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir; Be configured to the grand 35g (a.i.) of ethoxy sulphur/ha solution, again with clear water be diluted to 15,5g (a.i.)/ha concentration is subsequent use.
Azoles humulone solution: accurately take by weighing the former medicine of 0.0226g 90% azoles humulone; With the dissolving of 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir; Be configured to azoles humulone 80g (a.i.)/ha solution, again with clear water be diluted to 30,7g (a.i.)/ha concentration is subsequent use.
Blank solution: the 1mL vegetable oil adds the water of 400mL 0.1% agricultural newborn 600#.
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 grand with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds for ethoxy sulphur;
Y is an azoles humulone or with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0For ethoxy sulphur grand during with azoles humulone or two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibiting rate;
E for ethoxy sulphur grand during with azoles humulone or two kinds of pharmacy mix 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, when-10%≤E-E0≤10%, be expressed as summation action, when E-E0＜-10%, be expressed as antagonism.
Table 1 ethoxy sulphur grand and the azoles humulone and the toxicity test result of combination that be mixed thereof to nutgrass flatsedge
Evaluating drug effect: ethoxy sulphur is grand to be measured the result with the azoles humulone and the composition that is mixed thereof to the herbicidal effect of nutgrass flatsedge and sees table 1.It is thus clear that ethoxy sulphur is grand to show synergistic effect to nutgrass flatsedge, its E-E with the azoles humulone with 5+7,5+30,5+80,15+7,15+30,15+80,35+7,35+30, the 35+80 composition that is mixed
0Value is respectively 15.97,15.42,15.12,15.53,20.66,15.42,15.19,14.17,10.66, and is wherein best to the effect of nutgrass flatsedge with the composition that is mixed of 15+30, its E-E
0Value is 20.66, finds through the applicant, and ethoxy sulphur is grand composite also better to paddy field Monochoria vaginalis, Monochoria korsakowii, dichotomous fimbristylis herb, difformed galingale herb, cyperus iria, needle spikesedge herb preventive effect with the azoles humulone.
