Abstract
The invention relates to a weed killing composition containing pyraflufen ethyl and sulfonylurea compounds. The composition is mainly characterized in that the pesticide composition contains 1-60% of effective ingredient A, 1-80% of effective ingredient B and the balance of auxiliaries. The effective ingredient A is pyraflufen ethyl, and the effective ingredient B is selected from tribenuron-methyl or thifensulfuron methyl. The composition can be prepared into wettable powder, water dispersible granules, microemulsions, emulsions in water, oil suspensions and suspending emulsions. The pesticide composition provided by the invention can be used for controlling weeds in wheat fields and corn fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains pyrrole grass ether and sulfonyl urea compound, be used to prevent and treat wheat paddock and corn field weed.
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:
Pyrrole grass ether and active ingredient B are mixed to the active determination test report of weeds in field
Test objective: under the greenhouse pot culture condition, measured pyrrole grass ether and tribenuron-methyl or thifensulfuronmethyl and different blended combo thereof and closed herbicidal effect to lamb's-quarters; 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: lamb's-quarters (Chenopodium album).
Test medicine: pyrrole grass ether (Pyraflufen-ethyl) 95% former medicine, tribenuron-methyl (tribenuron-methyl) 95% former medicine, thifensulfuronmethyl (thifensulfuron-methyl) 97% former medicine, agricultural chemicals Co., Ltd of U.S. nation provides by Shaanxi.
The medicament configuration:
Pyrrole grass ethereal solution: accurately take by weighing the former medicine of 0.0107g 95% pyrrole grass ether,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to pyrrole grass ether 40g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 10g (a.i./hm with clear water again
2), 5g (a.i./hm
2) concentration is subsequent use.
Tribenuron-methyl solution: accurately take by weighing the former medicine of 0.0214g 95% tribenuron-methyl,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to tribenuron-methyl 80g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 20g (a.i./hm with clear water again
2), 8g (a.i./hm
2) concentration is subsequent use.
Thifensulfuronmethyl solution: accurately take by weighing the former medicine of 0.0314g 97% thifensulfuronmethyl,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to thifensulfuronmethyl 120g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 30g (a.i./hm with clear water again
2), 10g (a.i./hm
2) concentration is subsequent use.
Blank solution: 0.2mLDMF adds the clear water that contains 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 2～4 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.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 following:
E
0＝X+Y-XY/100
In the formula, X is that pyrrole grass ether is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that tribenuron-methyl or thifensulfuronmethyl are with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for pyrrole grass ether and tribenuron-methyl or two kinds of pharmacy mix of thifensulfuronmethyl to the theoretical value of target weeds fresh weight inhibiting rate; When E is pyrrole grass ether and tribenuron-methyl or two kinds of pharmacy mix of thifensulfuronmethyl 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.
