The weedicide composition can be prepared into wettable powder, water dispersible granules, suspending agents, suspending emulsion, EW (emulsion in water), and microemulsion, can be used for preventing and controlling annual weeds in corn fields and wheat fields, and has the characteristics of reduced application quantity, lowered residuals, good environmental compatibility and safety to human beings and animals.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains rimsulfuron and bromoxynil octanoate, be used for control of maize field, wheat paddock annual 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 height; (3) selectivity height.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 by the proportioning of adjusting different agricultural chemicals.

Embodiment
Below in conjunction with embodiment to further instruction of the present invention.
Implementation of an application example one:
Rimsulfuron and bromoxynil octanoate are mixed to the active determination test report of corn field weed
Test objective: under the greenhouse pot culture condition, measured rimsulfuron and bromoxynil octanoate and different blended combo thereof and closed herbicidal effect to the barnyard grass grass, and estimated its synergy, for the formulation development and the agriculture chemical registration field control effectiveness test of Mixed Pharmacy provides scientific basis.
For trying target: barnyard grass (Echinochlo crusglli L.).
Test medicine: rimsulfuron (cyhlofop-butyl) 99% former medicine, bromoxynil octanoate (pyriftlid) 95% former medicine provides by Shaanxi Welch Crop Protection Co., Ltd..
The medicament configuration:
Rimsulfuron solution: accurately take by weighing the former medicine of 0.0077g 99% rimsulfuron, with the dissolving of 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir, be configured to rimsulfuron 30g (a.i.)/ha solution, again with clear water be diluted to 20,10g (a.i.)/ha concentration is standby.
Bromoxynil octanoate solution: accurately take by weighing the former medicine of 0.0937g 95% bromoxynil octanoate, dissolve with the 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir, be configured to bromoxynil octanoate 350g (a.i.)/ha solution, again with clear water be diluted to 300,250g (a.i.)/ha concentration is standby.
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, will be in polypots for 15～20 sowings of examination target weed seed, 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.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 as follows:
E
0＝X+Y-XY/100
In the formula, X is that rimsulfuron is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is a bromoxynil octanoate or with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for rimsulfuron and bromoxynil octanoate or two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibiting rate; When E is rimsulfuron and bromoxynil octanoate 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, 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 rimsulfuron and bromoxynil octanoate and the toxicity test result of combination that be mixed thereof to barnyard grass
The phonetic sulphur of table 1 sulfone falls and the bromoxynil octanoate and the toxicity test result of combination to barnyard grass that be mixed thereof
Evaluating drug effect: rimsulfuron and bromoxynil octanoate and the composition that is mixed thereof see Table 1 to the herbicidal effect measurement result of barnyard grass.As seen, rimsulfuron and bromoxynil octanoate show synergistic effect with 10+250,10+300,10+350,20+250,20+300,20+350,30+250, the 30+300 composition that is mixed to the barnyard grass grass, its E-E0 value is respectively 15.24,16.37,18.26,19.24,20.88,17.72,12.16,11.35, with the 30+350 composition that is mixed the barnyard grass grass is shown addition, wherein best to the effect of barnyard grass with the composition that is mixed of 20+300, its E-E
0Value is 20.88.
