Abstract
The invention relates to a weeding composition containing carfentrazone-ethyl and triazine. The weeding composition is mainly characterized by containing 1-60 percent of active ingredient A, 1-80 percent of active ingredient B, and aid and other excipients, wherein the active ingredient A is carfentrazone-ethyl; the active ingredient B is selected from atrazine or terbutryn; and the composition can be prepared into wettable powder, water dispersible particles, a suspending agent, a suspending emulsion and the like. The weeding composition can be used for preventing and controlling weeds in wheat paddocks and corn fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of azoles humulone and triazines Herbicidal combinations of containing, 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, be that the agricultural chemicals of performance complement obtains best synergistic effect through the proportioning of adjusting different agricultural chemicals.

The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
Nineteen fifty-five has the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch, after, along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, is recognized extensively that to do be one of important measures of rationally using of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained bigger progress.
My company also is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers with the relevant composite product of atrazine, terbutryn about the azoles humulone.

Embodiment
Below in conjunction with embodiment the present invention is further illustrated.
Practice example one:
Azoles humulone 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 azoles humulone and atrazine or terbutryn and different blended combo thereof and closed to broadcasting the herbicidal effect of ma's punt-pole; 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: broadcast ma's punt-pole (Descurainia sophia (L.) Schur).
Test medicine: azoles humulone (carfentrazone-ethyl) 90% former medicine, atrazine (atrazine) 98% former medicine, terbutryn (terbutryn) 97% former medicine provides by Shaanxi Welch Crop Protection Co., Ltd..
The medicament configuration:
Azoles humulone solution: accurately take by weighing the former medicine of 0.0127g 90% azoles humulone; With the dissolving of 0.2mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir; Be configured to azoles humulone 45g a.i./ha solution, again with clear water be diluted to 30,15a.i./ha concentration is subsequent use.
Atrazine solution: accurately take by weighing the former medicine of 0.1918g98% atrazine; With the dissolving of 0.2mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir; Be configured to atrazine 750g a.i./ha solution, again with clear water be diluted to 500,250g a.i./ha concentration is subsequent use.
Terbutryn solution: accurately take by weighing the former medicine of 0.1937g97% terbutryn; With the dissolving of 0.2mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir; Be configured to terbutryn 750g a.i./ha solution, again with clear water be diluted to 500,250g a.i./ha concentration is subsequent use.
Blank solution: the 0.2mL cyclohexanone adds the water that contains 80mL 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.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 the azoles humulone is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that atrazine or terbutryn are with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for azoles humulone and atrazine or two kinds of pharmacy mix of terbutryn to the theoretical value of target weeds fresh weight inhibiting rate; When E is azoles humulone and atrazine or two kinds of pharmacy mix of terbutryn 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.

The control medicament: azoles humulone and terbutryn complex composition, produce by Shaanxi Welch Crop Protection Co., Ltd.'s research and development;
Contrast medicament: 40% azoles humulone water dispersible granules; 50% terbutryn suspending agent;
Method for using: convert behind 30 liters in the water evenly that cauline leaf sparges in each sub-district for every mu
Spraying time:, the weeds in field 1-3 leaf phase, carry out cauline leaf spraying 1 time in the wheat 2-4 leaf phase.
Investigation method and drug effect are calculated
Investigation weeds object is: broadcast annual weed such as ma's punt-pole, nutgrass flatsedge, clearvers, investigate back 15 days, 30 days to strain preventive effect of weeds and 30 days fresh weight preventive effect.
The visual test medicament does not have poisoning to wheat to be taken place.
The table 4 azoles humulone terbutryn built composition for preventing and controlling wheat paddock annual weed test of pesticide effectiveness
Can know by table 4 that azoles humulone and terbutryn are composite broadcasts annual weed such as ma's punt-pole, nutgrass flatsedge, clearvers good control efficiency is arranged to wheat paddock; And wheat there is certain raising the output; Preventive effect is better than single agent preventive effect; And contrast medicament, artificial weeding, with respect to significant difference between the rate of growth of clear water control treatment; And have quick-acting and lasting effect preferably; In this experimental drug scope, to wheat safety.
