Abstract

The invention provides a post-emergence compound herbicide for wheat fields. The post-emergence compound herbicide is prepared from, by weight, 10-60% of active components, 2-10% of a wetting agent, 2-8% of a dispersing agent, 1-6% of a penetrating agent, 0.5-6% of a thickening agent, 0.1-1% of an defoaming agent and the balance ethyl oleate, wherein the active components include mesosulfuron, florasulam and tralkoxydim in a weight ratio of 1-15:1-15:2-20, and the thickening agent is a mixture of activated sludge, hydroxyethyl cellulose and stearic acid. The post-emergence compound herbicide is capable of not only controlling gramineous weeds in the wheat fields but also controlling broadleaved weeds and is high in suspension stability to meet requirements of high-altitude low-temperature regions.

Description

Wheat paddock post-emergence complex weedicide
Technical field
The invention belongs to herbicide technology field is and in particular to a kind of wheat paddock post-emergence complex weedicide.
Background technology
It is the dispersion in oil insoluble in oily solid pesticide or immiscible liquids pesticide that pesticide oil suspension floats agent, from production Angle considers, typically requires active compound to be solid at room temperature, and the dissolubility (20 DEG C～40 DEG C) in disperse medium is less than The pesticide species of 100mg/l.The advantage that pesticide oil suspension floats agent is uniformly can to mix dispersion with oil with arbitrary proportion, easy to use, It is difficult to pollute environment, can directly or after dilution spray.Preparation for processing can make high dispersive, continuous phase by waterproof pulverization Suspension, the mean diameter of its particle, typically below 3 microns, substantially increases suspensibility in aqueous medium for the particle, strengthens Absorptions to medicament for the crops.
Semen Tritici aestivi is the most important cereal crops of northern China, concerning the grain security of national economy and country, mainly with the winter Based on Semen Tritici aestivi, account for 90%, and the weeds of wheatland have impact on the growth of Semen Tritici aestivi.Semen Tritici aestivi main weeds have 30 kinds about, such as see wheat Ma, Alopecurus, Herba bromi japonici, annual bluegrass, hard grass, caput grass, Miscanthus, Herba Galii Teneri, ox chickweed, Herba veronicae, neat, Folium rumicis acetosae of cracking rice Knotweed, Stellaria alsine Grim., Herba Viviae Sativae, sarson, descurainia sophia (l.) webb ex prantl, Herba Viviae Sativae, corn gromwell, Herba Capsellae, Herba Euphorbiae Helioscopiae, Herba seu Flos Convolvuli arvensves, field thistle, rice crock, Herba chenopodii, little Herba chenopodii, Herba Polygoni Avicularis and Herba Lamii Amplexicauliss, the wheat paddock foliar herbicide commonly used at present is only good to broadleaved herb prevention effect, to grass family Weed-control effect is poor, partly good to gramineous grass effect again not all right to broadleaved herb effect, simultaneously because some herbicides make year after year With causing resistance weed very big.Active component is to grassy weeds such as wild oat, Herba bromi japonici, amur foxtail and multiple dicotyledonous miscellaneous Grass has substantially anti-herbicidal effect to have fabulous safety to Semen Tritici aestivi.Wheat paddock major part grassy weed can effectively be prevented and kill off, but To part grass family and most of broadleaved herb effect on driving birds is not good.
Content of the invention
The present invention proposes a kind of wheat paddock post-emergence complex weedicide, and it is miscellaneous that can this herbicide not only prevent and kill off wheat paddock grass family Grass, but also broadleaved herb can be prevented and kill off, and suspension stability is high, meets the needs of High aititude low temp area.
The technical scheme is that and be achieved in that:
A kind of wheat paddock post-emergence complex weedicide, calculates according to percetage by weight, comprising:
Active component 10～60%, wetting agent 2～10%, dispersant 2～8%, penetrating agent 1～6%, thickening agent 0.5～ 6%th, defoamer 0.1～1%, balance of ethyl oleate；Described active component includes mesosulfuron, florasulam and oxime grass Ketone, the mass ratio of described mesosulfuron, florasulam and tralkoxydim is 1～15:1～15:2～20, and described thickening agent is The mixture of activated sludge, hydroxyethyl cellulose and stearic acid composition.
Further, calculate according to percetage by weight, described thickening agent is fine by 1～5% activated sludge, 40～60% ethoxys Dimension element and 35～50% stearic acid compositions.
Further, described wetting agent is fatty alcohol polyglycol ether sulfate, fatty alcohol-polyoxyethylene ether or alkylnaphthalene Sulfonic formaldehyde condensation compound.
Further, described dispersant is selected from sodium lignin sulfonate, calcium lignosulfonate, sodium methylene bis-naphthalene sulfonate or gathers Vinylpyrrolidone.
Further, described defoamer is n-octyl alcohol or silicone.
The preparation method of inventive compound:
1) active component, wetting agent, dispersant, defoamer and ethyl oleate are added into mixing kettle, in high shear stirring Under, so that material is sufficiently mixed uniformly, obtain mixture a；
2) activated sludge, hydroxyethyl cellulose and stearic acid be heated to 60～80 DEG C stir after, be cooled to room temperature, so Afterwards mixture a is added thereto with penetrating agent, is stirred continuously, mixed material is squeezed in sand mill and grinds, sand milling 2～3h, that is, Can.
Beneficial effects of the present invention:
1st, the thickening agent in the oil-suspending agent of the present invention is the mixing that activated sludge, hydroxyethyl cellulose and stearic acid form Thing.Activated sludge, hydroxyethyl cellulose are mixed in 60～80 DEG C of stirrings with stearic acid, form more stable gel network knot Structure, slows down the rate of settling of discrete particles, keeps effective ingredient to be in stable suspended state, compared with organobentonite and dioxy SiClx is compared, and the network structure that it forms is more stable, even if in the case of subzero 4 degree, it also can make discrete particles protect Hold preferable suspension effect.
2nd, open up good penetrability as object plane when the wheat paddock post-emergence complex weedicide of the present invention uses, decrease effective one-tenth Shunting is lost, and has notable synergistic to act on.
3rd, florasulam can prevent and kill off wheatland major part broad leaved weed, but to grassy weed to no effect.Tralkoxydim has Uptake and translocation effect, prevents and kill off multiple grassy weeds for Fructus Hordei Vulgaris, wheat paddock.After foliage application, rapidly plant is transferred to by absorption Strain whole body, weeds chlorosis, then withered.Compared with single dose, the complex weedicide speed of the present invention is fast, broad weed-killing spectrum, the dispenser phase Long, affected by environment little.
