Abstract
The invention relates to a weeding composition containing ethoxysulfuron and 2-methyl-4-chloro-sodium, which is mainly characterized in that: the weeding composition contains 0.1-60% of ethoxysulfuron, 0.1-80% of 2-methyl-4-sodium chloride and the balance of auxiliary agents, and can be prepared into wettable powder, water dispersible granules, suspending agents, suspoemulsions, aqueous emulsions and microemulsions. The weeding composition is used for preventing and controlling weeds in paddy fields, and has the characteristics of reducing the pesticide dosage, reducing pesticide residues, along with good environmental compatibility and safety to people and livestock.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of grand Herbicidal combinations with 2 first, 4 chlorine sodium 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.

3Na, chemical name: 2-methyl-4-chlorophenoxyacetic acid sodium.2 first, 4 chlorine sodium are phenoxy acetic acid class selectivity hormone herbicide, and root, stem, the leaf of medicine through plant absorbs, and can destroy the conducting tissue of dicotyledon, and making grows is interfered, the cauline leaf distortion, and basal part of stem expands chap or cracking.Volatility, speed of action are than 2, and 4-D is low to wait a moment, and sensitive plant receives the hormone-type poisoning symptom can occur behind the medicine.The activity of this weed killer herbicide in soil can keep 3～4 months, and broad-leaved class crops such as rape, soybean, cotton are very sensitive to 2 first, 4 chlorine sodium.Therefore, sensitive crops such as rape all can not use the 4 chlorine sodium weedings of 2 first in sowing or before transplanting, otherwise can cause rape leaf to be crispaturaed, petiole, the distortion of stem stalk, and the tip of a root expands, and the yellow of blade chlorisis, stiff embrittlement are final withered dead.Therefore, every plot of before rape is transplanted, using 2 first, 4 chlorine sodium weed killer herbicides, all can not cultivation of rape etc. sensitive crop.MCPA,MCP,methoxone is very sensitive to the seedling phase of gramineous plants, and 3-4 leaf after date resistance strengthens gradually, and late tillering state is the strongest, and panicle spike primordium differentiation stage susceptibility rises.Can be used for gramineous crop fields such as water paddy and wheat class, corn; Prevent and kill off convexutricle sedge herb class weeds, broad leaved weed and sedge weeds such as difformed galingale herb, Monochoria vaginalis, Herba Ammanniae Bacciferae, wild arrowhead, flat bar deer grass, knotweed, common vetch, clearvers, Herba Ranunculi Japonici, shepherd's purse, dandelion, Japanese Cayratia Herb, field thistle.Stable performance, effect is remarkable.
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 2 first, 4 chlorine sodium about ethoxy sulphur is grand.

Ethoxy sulphur swells solution: accurately take by weighing the grand former medicine of 0.0201g 95% ethoxy sulphur; With the dissolving of 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir; Be configured to the grand 35g (a.i.) of ethoxy sulphur/ha solution, again with clear water be diluted to 15,5g (a.i.)/ha concentration is subsequent use.
2 first, 4 chlorine sodium solutions: accurately take by weighing the former medicine of 0.0867g 88%2 first, 4 chlorine sodium; With the dissolving of 1mL cyclohexanone, add the clear water 400mL that contains 0.1% agricultural newborn 600#, stir; Be configured to 2 first, 4 chlorine sodium 300g (a.i.)/ha solution, again with clear water be diluted to 135,90g (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 2 first, 4 chlorine sodium or with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds;
E
0For ethoxy sulphur grand during with 2 first, 4 chlorine sodium or two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibiting rate;
E for ethoxy sulphur grand during with 2 first, 4 chlorine sodium or two kinds of pharmacy mix to target weeds fresh weight
The measured value of 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.
