Abstract
The invention discloses a composition of a weed killer in a cotton field, consisting of an active component, an auxiliary agent and a carrier, wherein the active component consists of trifloxysulfuron sodium salt and carfentrazone-ethyl; the weight ratio of the trifloxysulfuron sodium salt to the carfentrazone-ethyl is (1:50)-(50:1); and the weight of the active component is 5%-90% of the total weight of the composition. The preparation formulation of the composition is a wettable powder agent, a water dispersible granule or a suspending agent. The composition of the weed killer in the cotton field has the advantages that the weed killing spectrum is wide, the activity is high, the use amount is less, the cost is low, the influence on the environment and ecology is less, and the synergistic effect is good and the like.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, be specifically related to a kind of cotton field herbicidal composition.
Background technology
Cotton is the important economic crops of China, and its cultivated area and output are all at the forefront in the world, the plantation history in year surplus China existing 2000.Along with expanding economy, herbicide applications more and more widely, at present the kind of cotton field weed killer herbicide is many, but uses also relatively more chaotic.The preventive effect of some weed killer herbicide is relatively poor, though some preventive effect is good, easily cotton is produced poisoning.Present existing cotton field weed killer herbicide has that 33% cotton grass is peaceful, 51% cotton grass spirit, strong sprout herbicide, 28.6% fluorine second mixture, 37% careless spirit early etc.But these weed killer herbicides are to the seedling post processing poor effect of perennial weed (particularly broad leaved weed).
Carfentrazoneethyl (have another name called triazolone grass ester, the azoles humulone or the spirit of going out soon, CAS number is 128621-72-7) is that its chemical name is by the triazolineone weed killer herbicide of U.S. FMC Corp. exploitation: (
RS)-2-chloro-3-[2-chlorine]-5-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxygen-1H-1,2,4-triazol-1-yl)-the 4-fluorophenyl] ethyl propionate.Structural formula is as follows:
It is a kind of proporphyrinogen oxidase inhibitor, have active high, easily degraded, weeding fast, be subjected to advantages such as climatic effect is little, dispenser still can keep good effect under low temperature (≤5 ℃) condition.Can prevent and kill off annual broadleaf weed, grassy weed and nutgrass flatsedge.But it is because of mechanism of action restriction (no systemic activity), all make during use whole weeds abundant medicine, invalid to the weeds that grow after the dispenser.It is narrower also to exist the optimum period for applying fertilizer, and the longevity of residure is longer, the shortcoming that safety is relatively poor.
The chemical name of trifloxysulfuron sodium salt (CAS number is 199119-58-9) is: N-[(4,6-dimethoxy-2-pyrimidine radicals) carbamyl]-3-(2,2, the 2-trifluoro ethoxy)-2-pyridine sulfonamide sodium.Structural formula is as follows:
It is a kind of sulfonylurea herbicide, and its mechanism of action is the biologically active of the acetolactate synthestase (ALS) in the inhibition weeds, thereby kills weeds.Can prevent and treat most of broad leaved weeds and part grassy weed, the sedge weed such as the rhizome of nutgrass flatsedge are had special efficacy, can be used for having chemical sproof cotton field to use glyphosate.But its longevity of residure is longer, and the part succession crop is had certain influence, makes safety interval longer.

(application examples)
Be checking trifloxysulfuron sodium salt and the carfentrazoneethyl effect after composite, herbicidal composition to embodiment 1 to embodiment 6 has carried out field control effectiveness test, compares with 40% commercially available carfentrazoneethyl water dispersible granules and 75% trifloxysulfuron natrium brine dispersible granule simultaneously.Soil property is a loam, and main weeds is lady's-grass, eleusine indica, Amaranthus retroflexus and chickweed.Each dosing is that consumption is recommended in the land for growing field crops, establishes 9 processing altogether, and every processing repeats for 4 times, handles the sub-district for totally 36, and district's group is arranged at random, every sub-district area 20m
2, when growing a slice lobus cardiacus, cotton sprays medicine, and 30 days each weeds kind, strain numbers of handling of " Invest, Then Investigate " calculate preventive effect behind the medicine.Estimate by the Gowing method, result of the test sees Table 1.
Gowing method computing formula is: E
0(100-X)/100, wherein X is for using the preventive effect (%) of single agent A with the rate of application of p kg/ha, and Y is for using the preventive effect (%) of single agent B, E with the rate of application of q kg/ha for=X+Y
0Be the theoretical preventive effect (%) when using weed killer herbicide A+B with the rate of application of p+q kg/ha and mix mutually, E is the actual preventive effect (%) of weed killer herbicide A+B when mixing mutually, works as E-E
00 o'clock be synergistic effect, E-E
0＜0 o'clock for subtracting effect effect, E-E
0=0 o'clock is summation action.
Annotate: 100 expressions are prevented and kill off fully or are dead, and 0 expression is not prevented and kill off or damaged.
Calculate according to the Gowing method, after trifloxysulfuron sodium salt and carfentrazoneethyl were composite, to lady's-grass, the activity when Amaranthus retroflexus, the activity of weeding of eleusine indica and chickweed all are higher than the single agent of two kinds of independent uses had synergistic effect.Composite in addition back is killed the grass spectrum and has been obtained expansion, and application dosage also reduces greatly.
