Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the Herbicidal combinations of a kind of beflubutamid and Brominal, 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 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.
Beflubutamid (beflubufamid), molecular formula: C18H17F4NO2, molecular weight: 355.33.Beflubutamid is the benzene oxanamide class weed killer herbicide by the exploitation of Ube industry company, be mainly used in wheat paddock seedling rear defence and remove important broad leaved weed and grassy weed, have better effect with the isoproturon mix weeding,, succession crop is not had influence because its lasting period is moderate.
Brominal (bromoxynil), molecular formula: C7H3Br2NO, chemical name: 3,5-two bromo-4-carbonyls-1-cyano group benzene, this medicine are that cauline leaf is handled the contact killing type weed killer herbicide behind the selectivity seedling.Mainly absorb, in plant, carry out extremely limited conduction, make the plant tissue necrosis rapidly by suppressing photosynthetic each process via blade.Necrotic plaque appears in 24 hours intra vane chlorisis of dispenser.Under the strong condition of, illumination higher at temperature, speeding-up blade is withered.Be applicable to that crop fields such as wheat, barley, rye, wheat, Chinese sorghum, flax prevent and kill off broad leaved weed knotweed, lamb's-quarters, amaranth, conical silene herb, black nightshade, Siberian cocklebur, salsola collina, corn gromwell, field bindweed, corn-bind etc.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.
In recent years, people are frequent to be used and has concurrently to the safety of useful crop with to the so-called selective herbicide of the herbicidal effect of undesired plants, even but have the weed killer herbicide of high selectivity, because of various conditions such as the kind of meteorological condition, soil condition, crop, chemicals treatment periods, also produce poisoning sometimes in use.People are studying the use of the various poisoning palliatives of the such state of affairs of not expecting of reply.At present, China also comparatively payes attention to using with aspect the research of weed killer herbicide, is widely regarded as one of important measures that weed killer herbicide rationally uses, and 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 Brominal about beflubutamid.

Embodiment
Below in conjunction with embodiment to further instruction of the present invention.
Implementation of an application example one:
Beflubutamid and Brominal are mixed to the active determination test report of wheat paddock weeds
Test objective: under the greenhouse pot culture condition, measured beflubutamid and Brominal and different blended combo thereof and closed herbicidal effect, and estimated its synergy, for the formulation development and the agriculture chemical registration field control effectiveness test of Mixed Pharmacy provides scientific basis to shepherd's purse.
For trying target: shepherd's purse (Capsella bursa-pastoris).
Test medicine: beflubutamid (beflubufamid) 97% former medicine, Brominal (bromoxynil) 97% 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, dissolve with 1mLDMF, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to beflubutamid 170g a.i./ha solution, again with clear water be diluted to 115,75ga.i./ha concentration is standby.
Brominal solution: accurately take by weighing the former medicine of 0.0838g97% Brominal, with the 1mLDMF dissolving, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to Brominal 320g a.i./ha solution, again with clear water be diluted to 225,150g a.i./ha concentration is standby.
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, 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 2～5 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.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 as follows:
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 Brominal 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 Brominal to the theoretical value of target weeds fresh weight inhibiting rate; When E is beflubutamid and two kinds of pharmacy mix of Brominal 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 Brominal and the toxicity test result of combination that be mixed thereof to shepherd's purse
Table 1 beflubutamid and Brominal and the toxicity test result of combination that be mixed thereof to shepherd's purse
Evaluating drug effect: beflubutamid and Brominal and the composition that is mixed thereof see Table 1 to the herbicidal effect measurement result of shepherd's purse.As seen, beflubutamid and Brominal show synergistic effect to shepherd's purse, its E-E with 75+150,75+225,75+320,115+150,115+225,115+320,170+150,170+225, the 170+320 composition that is mixed
0Be worth respectively greater than 10%, so that wherein the composition that is mixed with 115+225 is best to the effect of shepherd's purse, its E-E
