Description

The Herbicidal combinations of a kind of containing beflubutamid and terbutryn
Technical field
The invention belongs to technical field of pesticide, be specifically related to the Herbicidal combinations of a kind of beflubutamid and terbutryn, for preventing and treating 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 ", (1) is safe, and this not only requires toxicity low, residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of current 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 effective approach, by adjusting the proportioning of different agricultural chemicals, be that the agricultural chemicals of performance complement obtains best synergistic effect.
Beflubutamid (beflubufamid), molecular formula: C 18h 17f 4nO 2, 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 except important broad leaved weed and grassy weed, with isoproturon mix weeding, have better effect, because its lasting period is moderate, on succession crop without impact.
Terbutryn (terbutryn), molecular formula: C 10h 19n 5s, chemical name: the special fourth amino-1,3,5-triazines of 2-methyl mercapto-4-ethylamino-6-, terbutryn belongs to inner-adsorption conduction-type herbicide, can be used for before bud, weeding after bud.
In recent years, the frequent use of people has concurrently the safety of useful crop and the so-called selective herbicide to the herbicidal effect of undesirable plant, even but there is the weed killer herbicide of high selectivity, because of various conditions such as the kind of meteorological condition, soil condition, crop, chemicals treatment periods, sometimes also produce poisoning in use.People are studying the use of the various poisoning palliatives of the so less desirable state of affairs of reply.At present, China also comparatively payes attention to aspect the mixed research of weed killer herbicide, is widely regarded as one of important measures of rationally use of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained greater advance.
My company is also devoted to the research and development of Herbicidal compositions.At present, about beflubutamid, have no report to the relevant composite product of terbutryn.

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): at the in-built quantitative soil of polypots of high 6cm, diameter 9cm, will be for 15~20 sowings of examination target weed seed in polypots, after covering the fine earth that 0.5~1cm is thick, be placed on cultivation in greenhouse, 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.After processing, examination material is placed in the greenhouse in and cultivates, and the growing state of routine observation target weeds is estimated target be injured symptom and growth inhibition situation, and claimed acrial part fresh weight or strain fresh weight, the toxicity action with form fresh weight inhibiting rate evaluation medicament to target weeds after 15d.
Investigation method:
Test is processed and to be estimated target be injured symptom and growth inhibition situation after 15d, and claims acrial part fresh weight, calculates fresh weight inhibiting rate (%).
Figure BDA0000076693560000091
Synergy evaluation method:
According to Gowing method, evaluate weed killer herbicide mode of application (NY/T 1155.7-2006), its formula is as follows:
E 0=X+Y-XY/100
In formula, X is beflubutamid fresh weight inhibiting rate to target weeds when alone with certain dosage; Y is terbutryn fresh weight inhibiting rate to target weeds when alone with certain dosage; E 0theoretical value to target weeds fresh weight inhibiting rate during for beflubutamid and two kinds of pharmacy mix of terbutryn; Measured value to target weeds fresh weight inhibiting rate when E is beflubutamid and two kinds of pharmacy mix of terbutryn.
Evaluation criterion: work as E-E 0during > 10%, be expressed as synergistic effect, as-10%≤E-E 0in the time of≤10%, be expressed as summation action, work as E-E 0during <-10%, be expressed as antagonism.
