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 that contains diflufenican, be used to prevent and treat 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 ", 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.
Diflufenican (diflufenican), molecular formula: C

3, chemical name: 3,6-two chloro-O-Anisic Acids.Dicamba is used for spraying behind the seedling, and medicament can be very soon absorbed by weeds, concentrate on the vigorous position of meristematic tissue and metabolic activity, hinders the normal activity of plant hormone and makes its death.The pesticide resistance that the gramineous plants performance is stronger.Broad leaved weed there is remarkable preventive effect.
Isopropyl methoxalamine (metolachlor), molecular formula: C
15H
22ClNO
2, chemical name: 2-ethyl-6-methyl-N-(1 '-methyl-2 '-methoxyethyl) chloro acetanilide.This medicine mainly absorbs through young shoot, and wherein monocotyledon weed mainly is that bud scale absorbs, and dicotyledon absorbs through young shoot and young root, and upwards conduction suppresses the growth of young shoot and root, before susceptible weeds is unearthed after germination or just unearthedly promptly be poisoned to death.The protein synthesis of the main sprout inhibition seed of the mechanism of action, next suppresses choline and infiltrates phosphide, disturbs lecithin to form.If soil moisture content is good, weeds were killed in the young shoot phase.Few like soil moisture, weeds are unearthed the back along with rainfall, and soil moisture increases, and weeds absorb medicament.The distortion of grassy weed lobus cardiacus, atrophy, whole strain is withered after other leaf shrinkages.The whole strain of broad leaved weed leaf shrinkage flavescence is withered.Because it is can the force rate broad leaved weed strong that the grassy weed young shoot absorbs isopropyl methoxalamine, 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, 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 about the relevant composite product of diflufenican with fluoroglycofen-ethyl, dicamba, isopropyl methoxalamine.

Embodiment
The embodiment of the invention is the method that adopts indoor biological activity determination and field trial to combine.Pass through indoor biological activity determination, the E-E after clear and definite two kinds of medicaments are composite by a certain percentage earlier
0Value on this basis, is carried out field trial again.
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 that diflufenican is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds;
Y is active component B or with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds;
E
0During for diflufenican and active component B or two kinds of pharmacy mix to the theoretical value of target weeds fresh weight inhibiting rate;
When E is diflufenican and active component B 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, 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.
In the formula: active component B is selected from following any one compound, a kind of in fluoroglycofen-ethyl, dicamba, the isopropyl methoxalamine.
