Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of grand Herbicidal combinations with amides compound of ethoxy sulphur that contains, be used to prevent and treat paddy 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.
Ethoxy sulphur swells (ethoxysulfuron), molecular formula: C

2S, chemical name: 2-[4-morpholinodithio-2-base oxygen-N-exalgine.Mefenacet is a kind of selectivity inner sucting conduction type weed killer herbicide.Main through bud scale and root absorption, conduct to young shoot and the tender leaf of weeds through xylem and phloem, stop weed growth point cell division to be extended, finally cause plant death.Strong to the transplanting rice selectivity, because solvability is low in water, so under the water conservation condition; The dispenser activity of weeding is the highest, and soil is very strong to these article absorption affinity, and the dose major part is adsorbed on upper soll layer after the dispenser; And at upper soll layer 1cm with interior formation processing layer; Can avoid contacting of paddy growth point and this medicament like this, make it produce higher safety, and the weeds such as barnyard grass grass that growing point is in upper soll layer are had stronger prevention fertility and kill ability; And the perennial weed of the seminal propagation on top layer also had inhibitory action, low to deep layer weeds effect.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.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 other weed killer herbicide is difficult to eliminate.Therefore; The composite important directions that also becomes domestic and international research new herbicides of using with of weed killer herbicide, 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; Work out a series of Herbicidal compositions, 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 the third careless amine about ethoxy sulphur is grand.

The third careless amine aqueous solution: accurately take by weighing the 0.1606g 95% the third former medicines of careless amine; With the dissolving of 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir; Be configured to third careless amine 600g (a.i.)/ha solution, again with clear water be diluted to 300,100g (a.i.)/ha concentration is subsequent use.
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; 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.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 following:
E
0＝X+Y-XY/100
In the formula, X is grand with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds for ethoxy sulphur;
Y is the third careless amine or with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0For ethoxy sulphur grand during with the third careless amine or two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibiting rate;
E for ethoxy sulphur grand during with the third careless amine 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, when-10%≤E-E0≤10%, be expressed as summation action, when E-E0＜-10%, be expressed as antagonism.
