Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains AC322140, be used for the control weeds in field.
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 ", namely (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 effective approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by the proportioning of adjusting different agricultural chemicals.
AC322140 (cyclosulfamuron), molecular formula: C

2O, chemical name: 3-(4-isopropyl phenyl)-1, the 1-dimethyl urea, this product is dry land herbicide.To preventing and kill off hard grass, net grass, amur foxtail etc. special efficacy is arranged, the herbicidal effect good stability, the herbicide wide spectrum, the optimum period for applying fertilizer is wide, and is high to crop safety, and toxicity is low, and is to the person poultry safety, easy to use.
Brominal (bromoxynil), molecular formula: C
7H
3Br
2NO, chemical name: 3,5-two bromo-4-carbonyls-1-cyano group benzene, this medicine are that cauline leaf is processed the contact killing type weed killer herbicide behind the selectivity seedling.Mainly absorb via blade, carry out extremely limited conduction in plant, each process by inhibited photosynthesis makes rapidly plant tissue downright bad.Necrotic plaque appears in 24 hours intra vane chlorisis of dispenser.Under, the stronger condition of illumination higher at temperature, speeding-up blade is withered.Be applicable to the crop fields such as wheat, barley, rye, corn, Chinese sorghum, flax and prevent and kill off broad leaved weed knotweed, lamb's-quarters, amaranth, conical silene herb, black nightshade, Siberian cocklebur, salsola collina, corn gromwell, field bindweed, corn-bind etc.
The salt of Brominal is bromoxynil octanoate, and bromoxynil octanoate also has good activity.
The chemical composition of each weed killer herbicide, formation and physic-chemical property all are distinguishing.Therefore, their herbicide ability and scope are also different.Some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
In recent years, people are frequent to be used and has concurrently to the safety of useful crop with to the so-called selective herbicide of the herbicidal effect of undesirable plant, even but have 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 such state of affairs of not expecting of reply.At present, China also comparatively payes attention to using with aspect the research of weed killer herbicide, is widely regarded as one of important measures that weed killer herbicide rationally uses, and has worked out a series of Herbicidal compositions, has obtained greater advance.
My company also is devoted to the research and development of Herbicidal compositions.At present, have no report about AC322140 with the relevant composite product of fluroxypyr, 2 first, 4 chlorine sodium, fluoroglycofen-ethyl, isoproturon, Brominal and salt thereof.

Test method: adopt potted plant cauline leaf facture (NY/T 1155.4-2006): at the in-built quantitative soil of the polypots of high 6cm, diameter 9cm, will be for 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 1～3 leaf phase 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.The examination material places in the greenhouse in and cultivates after processing, 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, with the toxicity action of form fresh weight inhibiting rate evaluation medicament to the target weeds.
Investigation method:
Range estimation target be injured symptom and growth inhibition situation are processed 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 mode of application (NY/T 1155.7-2006) according to the Gowing method, its formula is as follows:
E
0＝X+Y-XY/100
In the formula, X is AC322140 fresh weight inhibiting rate to target weeds when alone with certain dosage; Y is fluroxypyr fresh weight inhibiting rate to target weeds when alone with certain dosage; E
0During for a kind of two kinds of pharmacy mix in AC322140 and fluroxypyr, 2 first, 4 chlorine sodium, fluoroglycofen-ethyl, isoproturon, Brominal and the salt thereof to the theoretical value of target weeds fresh weight inhibiting rate; When E is a kind of two kinds of pharmacy mix in AC322140 and fluroxypyr, 2 first, 4 chlorine sodium, fluoroglycofen-ethyl, isoproturon, Brominal and the salt thereof to the measured value of target weeds fresh weight inhibiting rate.
