Abstract
The invention relates to weeding composition containing diflufenican, which comprises an active ingredient A, an active ingredient B, auxiliary agent and other excipients. The active ingredient A is diflufenican, and the active ingredient B is selected from one of the following compounds: fluoroglycofen-ethyl, dicamba or metolachlor. The weeding composition is mainly characterized in that: the weight percentage of the active ingredient A is 1 percent to 60 percent, and the weight percentage of active ingredient B is 1 percent to 80 percent; and the weeding composition can be made into wettable powder, water dispersion granule, suspending agent, suspension emulsion, water emulsion and micro emulsion, can be used for preventing weeds in soybean field, wheat field and corn field, and has the characteristics of less use of farm chemicals, less residue of farm chemical, good environment compatibility and safety to the human beings and animals.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations containing diflufenican, for preventing and treating Soybean Field, wheat paddock, 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 ", (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 effectively approach, make the agricultural chemicals of performance complement obtain best synergistic effect by adjusting the proportioning of different agricultural chemicals.

2, chemical name: 2-ethyl-6-methyl-N-(1 '-methyl-2 '-methoxyethyl) chloro acetanilide.This medicine mainly absorbs by young shoot, and wherein monocotyledon weed is mainly that bud scale absorbs, and dicotyledon absorbs by young shoot and young root, and upwards conduction suppresses the growth of young shoot and root, and susceptible weeds is before germination is unearthed afterwards or be just unearthedly poisoned to death.The protein of the main sprout inhibition seed of the mechanism of action is synthetic, secondly suppresses choline and infiltrates phosphide, disturbs lecithin to form.If soil moisture content is good, weeds were killed in the young shoot phase.As few in soil moisture, after weeds are unearthed, along with rainfall, soil moisture increases, and weeds absorb medicament.The distortion of grassy weed lobus cardiacus, atrophy, after other leaf shrinkages, whole strain is withered.The whole strain of broad leaved weed leaf shrinkage flavescence is withered.Due to grassy weed young shoot, to absorb isopropyl methoxalamine energy force rate broad leaved weed strong, thereby the effect that this medicine is prevented and kill off grassy weed is better than broad leaved weed far away.
The chemical composition of each weed killer herbicide, formation and physic-chemical property are all distinguishing.Their herbicide ability and scope are also different, and some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate other weed killer herbicide and be difficult to the weeds of eliminating.Therefore, the composite mixed important directions that also becomes domestic and international research new herbicides of weed killer herbicide, China also comparatively payes attention to aspect the mixed research of weed killer herbicide, is extensively recognized as one of important measures of rationally use of weed killer herbicide, work out a series of Herbicidal compositions, obtained greater advance.
My company is also devoted to the research and development of Herbicidal compositions.At present, have no report about diflufenican to the relevant composite product of fluoroglycofen-ethyl, dicamba, isopropyl methoxalamine.

Embodiment
The embodiment of the present invention is the method that adopts indoor biological activity determination and field trial to combine.First by indoor biological activity determination, the E-E after clear and definite two kinds of medicaments are composite by a certain percentage
0value, on this basis, then carries out field trial.
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 2～4 leaf phases and carry out cauline leaf spraying processing, every alms bowl spraying liquid 1mL, every processing repeats 4 times, and establishes the not contrast that is treated to containing medicament.Processing is placed in greenhouse 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 after 15d, evaluate the toxicity action of medicament to target weeds with form fresh weight inhibiting rate.
Investigation method:
Test is processed and is estimated target be injured symptom and growth inhibition situation after 15d, and claims acrial part fresh weight, calculates fresh weight inhibiting rate (%).
Synergy evaluation method:
Evaluate weed killer herbicide mode of application (NY/T 1155.7-2006) according to Gowing method, its formula is as follows:
E
0＝X+Y-XY/100
In formula, X is diflufenican fresh weight inhibiting rate to target weeds when alone with certain dosage;
Y is active component B or the fresh weight inhibiting rate to target weeds when alone with certain dosage;
E
0theoretical value to target weeds fresh weight inhibiting rate during for diflufenican and active component B or two kinds of pharmacy mix;
Measured value to target weeds fresh weight inhibiting rate when E is diflufenican and active component B or two kinds of pharmacy mix.
Evaluation criterion: work as E-E
0when > 10%, be expressed as synergistic effect, as-10%≤E-E
0≤ 10% time, be expressed as summation action, work as E-E
0when <-10%, be expressed as antagonism.
