Abstract
The invention provides a weed killer composition for preventing and removing weeds in corn fields. The weed killer composition comprises two active components including nicosulfuron and mesotrione. The weight ratio of the nicosulfuron to the mesotrione is (1-2) to (2-1). The weed killer composition provided by the invention has good application effects on preventing and removing grassy weeds or broad leaf weeds in the corn fields.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, specifically, relate to a kind of herbicidal composition of Control Weeds in Maize Field.
Background technology
Weeds are important component parts of agricultural ecosystem, win honour for, strive fertilizer, strive water with crops, are to affect plant growth to cause one of key factor of the underproduction.Mesotrione is before a kind of novel selectivity inner sucting conduction type maize seedling and herbicide after seedling, it is effective inhibitor of HPPD (4 one hydroxyphenyl pyruvic acid dual oxide enzyme), can suppress the biosynthesis of carotenoid, weeds are occurred after albefaction dead, it can be by the leaf of plant and root absorption, the transmission downwards to top.Mesotrione can effectively be prevented and kill off the broadleaf weeds such as corn field dayflower, piemarker, knotweed, acalypha copperleaf, lamb's-quarters, Amaranthus retroflexus, the monocotyledon weeds such as lady's-grass, barnyard grass, green foxtail is also had to certain effect of preventing and kill off, to corn safety.Under normal crop rotation, to succession crop as wheat class, rape, potato, beet safety.But mesotrione is limited to the preventive effect of the grassy weeds such as lady's-grass, and expensive, and unit are use cost is large, and it is restricted on promoting the use of.
Nicosulfuron (nicosulfuron), 2-(4,6-dimethoxypyridin-2-base carbamyl aminosulfonyl)-N, N-dimethyl nicotinamide.Nicosulfuron is interior absorption, high efficiency corn weed killer herbicide, after low dosage bud with effectively preventing and kill off multiple annual gramineous weed, broad leaved weed and sedge weed in corn field.It is absorbed rapidly by leaf and root, and conducts rapidly by xylem and phloem, stops the synthetic of branched-chain amino acid by acetolactate synthestase.After using nicosulfuron, weeds stop growing immediately, and 4～5 days young leaves fade, necrosis, and progressively expand to whole plant, plant death in 20～25 days after processing under general condition.This medicine not only has cauline leaf processing effect, also has the front activity of weeding of bud.Corn has good drug resistance to this medicine, occurs temporary transient chlorisis or slight hypoevolutism, but generally can recover rapidly and the not underproduction after processing.
Corn field herbicide is limit by crop safety at present, herbicide spectrum is also limited, use separately a kind of weed killer herbicide single dose can not control completely effectively the generation of corn field weed, moreover some weed killer herbicide is due to water-soluble large or the field lasting period is oversize, consumption is excessive or dispenser is inhomogeneous all easily causes the residual hazard to this season crop or succession crop.
Summary of the invention
In view of this, the invention provides a kind of herbicidal composition of Control Weeds in Maize Field.
The invention solves the technical scheme that its technical problem adopts: a kind of herbicidal composition of Control Weeds in Maize Field, it is characterized in that, described herbicidal composition comprises nicosulfuron, two kinds of active components of mesotrione, and wherein the weight ratio of nicosulfuron, mesotrione is 1～2:2～1.
Preferably, the weight ratio of described nicosulfuron, mesotrione is 1:1.
Preferably, the mass percent of described active component in herbicidal composition is 5-70%.
Preferably, combination dosage form can be upper any formulation allowing of agricultural.
Herbicidal composition provided by the invention can also comprise emulsifier, wetting agent, dispersant, vegetable oil, mineral oil, filler, thickener, water, disintegrant, binding agent.
In insecticides adjuvant, emulsifier is the compound of one or more anion, non-ionic surface active agent, non-ionic surface active agent is as fatty acid esters of sorbitan, alkylphenol-polyethenoxy polyethenoxy ether, polyoxyethylene alkyl amine etc., and anion surfactant is as calcium dodecyl benzene sulfonate, neopelex etc.; Wetting agent can be lauryl sodium sulfate, JFC, neopelex, pull open powder, polyoxyethylene nonylphenol ether, octyl phenol polyoxy ethene sodium sulphate, aliphatic alcohol sulfate, alkylnaphthalene sulfonate, fatty acid amide N-metilsulfate, aliphatic alcohol polyethenoxy sodium sulphate, fatty acid sulphate, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, alkyl benzyl dimethyl ammonium chloride, alkyl amine oxide etc.; Dispersant can be sodium lignin sulfonate, NNO, polyoxyethylene polyoxypropylene base ether block copolymers, alkylphenol-polyethenoxy base ether phosphate or water-soluble high-molecular compound CMC, PVA etc.; Thickener has aluminium-magnesium silicate, xanthans, white carbon etc.; Disintegrant can be one or more among starch and derivative sodium carboxymethyl starch, low-substituted hydroxypropyl cellulose, crospolyvinylpyrrolidone, alginic acid and salt and clay etc.; Adhesive is one or more in the surfactants such as formaldehyde condensation products, polycarboxylic acid and water-soluble high-molecular compound CMC, the PVA of lignosulfonates, alkylbenzenesulfonate, alkylnaphthalene sulfonate.
Described filler can be solid packing and liquid filler.Solid packing is mainly organic or inorganic solid, inert material, as talcum powder, potter's clay, diatomite, aluminium-magnesium silicate, white carbon, pyrophillite, precipitated calcium carbonate etc.; And liquid filler mainly comprises that part oils solvent is as soya-bean oil, cottonseed oil, palm oil, cocoa butter, rapeseed oil, Semen Ricini oil, turpentine oil, enriching vegetable oil, sunflower oil, paraffin series oil, the senior fatty hydrocarbon ils of methyl naphthalene and water etc.
The present invention is to prevent and kill off in corn field in various grass family or broad leaved weed effect good.
