Abstract
The invention discloses a kind of complex herbicidal composition, the active ingredient of the Herbicidal combinations is Mediben, MCPA,MCP,methoxone and pinoxaden, and wherein the weight ratio of Mediben, MCPA,MCP,methoxone and pinoxaden is 0.5～5:1～15:1～30, in addition also contain the auxiliary agent such as dispersant, emulsifying agent, wetting agent, antifreezing agent, thickener, disintegrant, binding agent, filler, solvent in the complex herbicidal composition, the formulation of complex herbicidal composition can be wettable powder, suspending agent, water dispersion granule and missible oil.The complex herbicidal composition of the present invention is significantly improved compared with the herbicidal effect of single dose, can be used for while preventing and kill off the broad leaved weed of wheat paddock, nutgrass flatsedge and grassy weed, weed control spectrum not only can be expanded, increase preventive effect, delay Weed Resistance, the consumption of Mediben can also be reduced, reduce use cost, improve the security to wheat.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, specifically, be related to a kind of containing Mediben,
The complex herbicidal composition of three kinds of active components of MCPA,MCP,methoxone and pinoxaden, the Herbicidal combinations can be applicable to wheat paddock and remove
Grass.
Background technology
Wheat is the staple food crop of China, and wheat paddock borough chief grass is very common, and a lot of peasants worry weeds impact
The yield of wheat, in recent years, as the continuous expansion of wheat planting area, crop smothering also day by day expand, is made to reduce crop smothering
The economic loss for becoming, it is ensured that the growth of wheat is more stable, reduces labor intensity, at the same also because chemical weed control convenient, quick-acting,
Control time is long, and chemical weed control is gradually received by people.
In recent years, increasing and chemical control technology being widely popularized in agricultural production with herbicide kind, chemistry
Weeding is widely used to each period of wheat growth, but as drug of choice is incorrect, the undesirable or generation medicine of prevention effect
The phenomenons such as evil occur repeatedly, and medicinal herb grower is accomplished by selecting a kind of high activity, herbicide wide ranges and the herbicide to plant height safety.
Reasonable selection herbicide can not only reduce the labour intensity of friend peasant, shorten working time, but also can reduce and cultivate cost,
Reach the purpose of volume increase.
Mediben, the chloro- O-Anisic Acid of chemistry entitled 3,6- bis-, trade name Dicamba, wheat straw prestige, are that one kind has
The auxins herbicide after seedling of selective and Uptake and translocation, is formulated in 1961 by Wei Ersi Cole chemical company of the U.S.,
Registration is obtained in Canada within 1963, report and obtain within 1967 that the U.S. registers first as herbicide.Mediben belongs to styrax
Sour serial herbicide, the mechanism of action belong to hormone like herbicide, and weeds poisoning symptom is similar to the effect symptom of auxin material,
There is notable preventive effect to annual and perennial broadleaf weed, compare peace for gramineous crops such as wheat, corn, millet, paddy rice
Entirely, for preventing and kill off clearvers, corn-bind, lamb's-quarters, ox chickweed, common vetch, broadcasting ma's lettuce, Siberian cocklebur, Bao Shuocao, field bindweed, field thistle, ask
Chaste tree, carp intestines etc., after seedling are sprayed, and medicament is conducted by bast and xylem up and down by the stem of weeds, leaf, root absorption, hinder
The normal activity of plant hormone, so which is dead.
MCPA,MCP,methoxone, chemical name：2- methyl -4- tomatotone, belongs to phenoxy acetic acid class selectivity Uptake and translocation
Hormone like herbicide, can enter in plant body from stem, leaf, and degraded is slow, therefore can accumulate finite concentration, so as to disturb in plant body
Hormonal balance, destroys nucleic acid and protein metabolism, so destroying the conducting tissue of plant, developing weed growth and being interfered,
Cauline leaf is distorted, and basal part of stem expands thicker or cracking, and weeds hormone-type poisoning symptom occur after receiving medicine.MCPA,MCP,methoxone is in wheatland
Used in the preventing and treating of weeds widely, its herbicide scope is wide, and herbicidal effect is rapid, and generally 2-3 days weeds are turned round after administration
Bent deformation, part cauline leaf redden, and 7-15 days dead, can effectively prevent and kill off the broad-leaveds such as Herba Galii Teneri in wheat paddock, common vetch, shepherd's purse
Weeds and budding period grassy weed.
Pinoxaden belongs to neophyl pyrazolines herbicide, and with Uptake and translocation, the mechanism of action is acetyl-coa carboxylase
Enzyme (ACC) inhibitor, causes aliphatic acid biosynthesis block, stops cell division, and cell membrane is destructurized containing fat, causes
Weeds are dead.Pinoxaden is the conventional herbicide of wheat paddock, belongs to after seedling grass family foliar herbicide, to preventing and kill off as seen wheat
The grassy weeds such as ma, Alopecurus, Salvia japonica, wild oat, rye grass, annual bluegrass, green bristlegrass are especially effective.
Mediben has that herbicide power is strong, drug effect is rapid, consumption is few, holding effect is moderate, high financial profit the features such as, but its herbicide
Spectrum is narrower, only has preventive effect to broad leaved weed, and price is higher；By comparison, the mu low cost of MCPA,MCP,methoxone, weed control spectrum are wider,
Most of annual and perennial broad leaved weeds and nutgrass flatsedge can be prevented and kill off, also has better effects to multiple 4-8 leaf advanced age broadleaved herbs.But
It is that, based on grassy weed and broad leaved weed, the only compounding herbicide of Mediben and MCPA,MCP,methoxone is totally anti-for weeds of wheat
Effect is relatively low, and pinoxaden is excellent to grassy weed preventive effect.In order to protect wheat from Weed infestation in all directions, remove several
Careless agent is compounding with while broad leaved weed, nutgrass flatsedge and the grassy weed of preventing and kill off wheat paddock have important practical significance.With wheat straw
Fear, MCPA,MCP,methoxone and pinoxaden not only can expand weed control spectrum for the complex herbicidal composition of active ingredient, increase preventive effect, prolong
Slow Weed Resistance, can also reduce the consumption of Mediben, reduce use cost, improve the security to wheat.
Content of the invention
The technical problem of solution
The technical problem to be solved is to provide a kind of containing the compounding of Mediben, MCPA,MCP,methoxone and pinoxaden
Herbicidal combinations, for preventing and kill off broad leaved weed, nutgrass flatsedge and the grassy weed of wheat paddock simultaneously, not only can expand weed control spectrum,
Increase preventive effect, delay Weed Resistance, the consumption of Mediben can also be reduced, reduce use cost, improve the security to wheat.
