Abstract
The invention relates to herbicide compositions and particularly relates to a paddy field molinate type herbicide composition. The paddy field molinate type herbicide composition is prepared from the following raw materials in parts by weight: 20-25 parts of molinate, 15-35 parts of bensulfuron methyl, 5-8 parts of pyrazosulfuron-ethyl, 5-8 parts of cyclosulfamuron, 12-20 parts of ethoxysulfuron and 3-8 parts of cyclosulfamuron. The paddy field molinate type herbicide composition provided by the invention is used for preventing and treating paddy field weeds and also has the efficient killing effects on gramineae grassy weeds (such as leptochloachinensis nees and echinochloa crusgalli and the like), cyperaceae weeds and other broadleaf weeds; and the dosage and the herbicide application times are reduced, the herbicide application lasting period is long and the weed damages of a whole growth period in a paddy field can be effectively controlled after one time of herbicide application.
Description
Technical field
The present invention relates to herbicidal composition, particularly a kind of paddy field molinate class herbicidal composition.
Background technology
Paddy field weed has developed into a huge plant community, and paddy field weed group is by a large amount of absorption of light, soil nutrient etc. and predation, and severe weakness paddy growth situation, has a strong impact on yield and quality of rice.Current paddy field weed kind is many, existing grassy weed, and have again moleplant seed in sedge weed and broad leaved weed, particularly grassy weed, barnyard grass, lady's-grass crop smothering serious, the crop smothering emergence period is long.And herbicides for use in paddy all has stronger selectivity usually, good and very poor to another section's weeds herbicidal effect to a certain section weeds herbicidal effect, therefore can only repeatedly, multi items, multiple dose medication, excess and pesticide abuse bring the negative effects such as rice quality decline and environmental pollution, turn increase drug cost.
Summary of the invention
Technical problem solved by the invention is to provide a kind of herbicide composition for paddy fields.
The technical solution used in the present invention is:
A kind of paddy field molinate class herbicidal composition, described composition is made according to the raw material of following weight fraction: molinate 20-25 part, bensulfuron-methyl 15-35 part, pyrazosulfuron 5-8 part, AC322140 5-8 part, ethoxysulfuron 12-20 part, the grand 3-8 part of cyclammonium sulphur.
Preferably, described composition is made according to the raw material of following weight fraction: molinate 18 parts, bensulfuron-methyl 30 parts, pyrazosulfuron 6 parts, AC322140 6 parts, ethoxysulfuron 15 parts, grand 6 parts of cyclammonium sulphur.
Preferably, described herbicidal composition is oil-suspending agent (OF), wetting powder (WP), water dispersible granules (WG), granula (GR) or tablet (TA).
Oil-suspending agent (OF) is high dispersive, the stable suspension system that active component is formed in non-water system dispersion medium.Oil-suspending agent of the present invention is made up of active component, vegetable oil and/or mineral oils solvent, emulsifier, wetting agent, dispersant, and wherein wetting agent and dispersant can be selected to add or do not add according to formulation requirements, also can only add wherein a kind of.Wherein plant oil solvent can be soya-bean oil, cottonseed oil, palm oil, cocoa butter, rapeseed oil, Semen Ricini oil, turpentine oil, enriching vegetable oil, sunflower wet goods; Mineral oil can be paraffin series oil, methyl naphthalene higher aliphatic hydrocarbon ils etc.Emulsifier can be the compound of one or more anion and non-ionic surface active agent, also can be the compound of one or more anion surfactants, also can be the compound of one or more non-ionic surface active agents.Non-ionic surface active agent is as alkylphenol polyoxyethylene class, Ben-zylphenol Polyoxyethyl Ether class, benzylbiphenyl phenol polyethenoxy polyoxypropylene ethers, phenethyl phenol polyethenoxy ether and similar kind, fatty alcohol-polyoxyethylene ether and analog, fatty acid esters of sorbitan, alkylphenol-polyethenoxy polyethenoxy ether, polyoxyethylene alkyl amine, Span etc.Anion surfactant is as alkylbenzenesulfonate, alkyl benzene sulfonate calcium salt, alkyl sulfonic acid alkylnaphthalene sulfonate, aliphatic alcohol sulfate, alkyl phosphate and similar kind thereof, polyoxyethylene carboxylate phosphate, alkylphenol polyoxyethylene phosphate and similar kind etc.Non-ionic surface active agent in emulsifier and the part by weight of anion surfactant are 1 ~ 10: 1, and preferred proportion is 2 ~ 8: 1, and wetting agent is as lauryl sodium sulfate, JFC etc., and dispersant has sodium lignin sulfonate, NNO etc.In the formulation, the weight ratio of active component is 5 ~ 80%, the weight ratio of emulsifier is 1 ~ 20%, the weight ratio of wetting agent is 0.1 ~ 15%, the weight ratio of dispersant is 0.1 ~ 15%, and when wetting agent and dispersant use simultaneously, the weight ratio of wetting agent is 0.1 ~ 10%, the weight ratio of dispersant is 0.1 ~ 10%, and surplus is oil.
Wetting powder (WP) be by after the Homogeneous phase mixing such as active component and solid carrier, dispersant, wetting agent through air-flow crushing manufacture.Described solid carrier: can be natural minerals class, as silica gel, silicate, talcum, kaolin, lime stone, potter's clay, dolomite, diatomite; Also can be synthetic vectors class, such as white carbon, precipitated calcium carbonate.Dispersant: as lignosulfonates, naphthalene sulfonic acid-formaldehyde condensation product (comprising dispersant NNO) and alkylphenol polyoxyethylene, formaldehyde condensation products sulphate.Wetting agent has lauryl sodium sulfate, JFC etc.In the formulation, the content of active component is 5 ~ 80%, and the weight ratio of dispersant is 0.1 ~ 15%, and the weight ratio of wetting agent is 0.1 ~ 15%, and surplus is solid carrier.
Water dispersible granules (WG) makes again dry suspending agent (DF) be by active component, wetting agent, dispersant, adhesive and disintegrant, by being formed with the mixing granulation of water.For active component of the present invention, its weight ratio is 5 ~ 8%; Can be one or more among sodium alkyl sulfate, sodium alkyl benzene sulfonate plasma type surfactant for wetting agent of the present invention, its weight ratio be 0.1 ~ 15%; Can be one or more among starch and derivative, alginic acid and salt and clay etc. for disintegrant of the present invention, consumption be 0.1 ~ 20%; For one or more materials that dispersant of the present invention and adhesive are among lignosulfonates, alkylbenzenesulfonate, the formaldehyde condensation products of alkylnaphthalene sulfonate and polycarboxylic acid surfactant, usual consumption 2 ~ 35%.
