Abstract
The invention provides a compound herbicide containing iodosulfuron-methyl sodium. The compound herbicide is characterized by comprising two active ingredients including iodosulfuron-methyl sodium and cyclosulfamuron, wherein the weight ratio of iodosulfuron-methyl sodium to cyclosulfamuron is (1-40):(1-30). The herbicide is safe, has high speed, wide weed control spectrum and long herbicide application period and is slightly affected by the environment.
Description
Technical field
The present invention relates to a kind of compound herbicide that contains iodosulfuron-methyl-sodium.
Background technology
Wheat is the most important cereal crops of northern China, concerning the grain security of national economy and country.Area is planted more than 2,500 ten thousand hectares in the annual whole nation, mainly concentrates on Huang-Huai-Hai plain and the Yangtze river basin, mainly take winter wheat as main, accounts for 90%, and all the other 10% are spring wheat, mainly concentrate on outlying or high and cold area.In recent years, along with the downslide of rape price and constantly riseing of wheat, wheat planting area was also rising to some extent.
Wheat paddock common weed mainly contains amur foxtail, Alopecurus, Wang grass, caput grass, hard grass, annual bluegrass, candle grass, wild oat, bromegrass, lolium temulentum, Herb of Common Nipplewort, Chinese ixeris herb, lyrate hemistepta herb, common sow thistle, annual fleabane herb, field thistle, chickweed, ox chickweed, Siberian cocklebur, corn gromwell, common vetch, narrow-leaved vetch, bird retch, hairy tare, shepherd's purse, Hairy Bittercress, Veronica, Persian Veronica, Carolina Cranesbill Herb etc.Be subject to temperature, rainfall, soil property, the weed seed Effects of Factors such as buried depth and cropping system in soil, wheat weeds group and generation quantity difference between interzone, field are large.
It is long that weeds of wheat goes out careless harm time, suppressed by winter low temperature, has two germination peaks throughout the year, and first germination peak was at after planting 10~30 days, and second germination peak is after the beginning of spring, temperature went up.The wheatland of early sowing, Autumn Rain is many, temperature is high, and before the winter, grass output amount is large; Spring, rainwater was also many, and weeds generating capacity is also large.Before batch tuber of dwarf lilyturf in evening, grass output amount is few, and spring, grass output amount was more.Meet autumn and winter arid, more time of spring rain, before the early sowing wheatland winter, grass output amount is few, often has a large amount of weed germinations after the beginning of spring.Because of preceding crop difference, wheat weeds generation quantity and grass are obviously different mutually.Drought stubble wheatland is take broad leaved weed as main, the grassy weeds such as normal association caput grass, candle grass, annual bluegrass; Rice stubble wheatland is take grassy weed as main, the broad leaved weeds such as association clearvers, Herb of Common Nipplewort, shepherd's purse.Winter, wheatland was take grassy weed harm as main, and after the spring, broad leaved weed growth is vigorous.
AC322140, has another name called the gold autumn.Chemical name: 1-{[O-(ring propiono) phenyl] sulfonamides }-3 (4,6-dimethoxy-2-pyridinyl)-urea.This medicine can be by weeds root system and Foliage Absorption, in plant body, conduct, its mechanism of action is mainly by suppressing the activity of acetolactate synthestase in weeds body, thereby the branched-chain amino acids such as obstruction leucine, isoleucine, a word used in person's names propylhomoserin is synthetic, make cell stop division, finally cause weeds death.Do after cauline leaf processing, susceptible weeds stops growing, and leaf look moves back green, according to different environmental conditions, just can make weeds completely withered after several weeks.This medicine can be used for rice transplanting Honda, also can be used for direct sowing rice field and prevents and kill off broad leaved weed and sedge weed, under high dose, barnyard grass is had to good inhibitory action, and the anti-weeds flat bar of perennial difficulty bamboo trunk grass is also had to stronger inhibition.
Summary of the invention
technical problem
In view of this, the technical problem to be solved in the present invention is that a kind of compound herbicide is efficiently provided.
solution
In order to solve the problems of the technologies described above, the invention provides a kind of compound herbicide that contains iodosulfuron-methyl-sodium, it is characterized in that, described compound herbicide comprises iodosulfuron-methyl-sodium, two kinds of active components of AC322140, and wherein the weight ratio of iodosulfuron-methyl-sodium, AC322140 is 1~40:1~30.
Preferably, the weight ratio of iodosulfuron-methyl-sodium, AC322140 is 2:1.
Preferably, the mass percent of described active component in compound herbicide is 5-70%.
Preferably, described combination dosage form is suspending agent.
beneficial effect
The invention provides a kind of safety, speed is fast, broad weed-killing spectrum, and the dispenser phase is long, little weed killer herbicide affected by environment.
Embodiment
FORMULATION EXAMPLE
Inventor's discovery, this formula adopts the effect of oil suspending agent (oil suspending agent, aqueous suspension) better.
Suspending agent refers to former solid pesticide medicine is dispersed in to the preparation in water with 4 microns of following particulates, and international code name is SC, claims again dense suspension, flowable, aqueous suspension, colloidal suspending agent.The suspension in aqueous medium is ground, is dispersed in to the solid pesticide and the auxiliary agent process that are insoluble in water.Continuous phase is water.Due to the not dust from flying problem as can wet-milling (WP) of SC, nonflammable explosive, particle diameter is little, and biologically active is high, and proportion is larger, and packaging volume is less, relatively other formulations of pesticide safety and environmental protections.
Suspending agent is divided into two kinds of aqueous suspension agent and oil-suspending agents.Aqueous suspension agent is water as solvent.Oil-suspending agent is take oils as primary solvent, not moisture.
Dispersant is lignosulfonates, lignin calcium iodate, ethoxylated dodecyl alcohol sodium sulphate, how formaldehyde condensation products sulfonate of alkyl, neopelex, lauryl sodium sulfate, alkyl polyoxyethylene ether sulfonate, alkylphenol-polyethenoxy base ether formaldehyde condensation products, alkylphenol-polyethenoxy base ether Nonyl pheno base ether, polyoxyethylene polyoxypropylene base ether block copolymers, pull open powder, polymeric carboxylic salt, di-2-ethylhexylphosphine oxide bitter edible plant sodium sulfonate, polyvinyl alcohol, the naphthalene sulfonate of modification, polycarboxylate, alkylnaphthalene sulfonate, alkylphenol polyoxyethylene, EO/PO block polyether, JFC, 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, the composition of one or more in alkyl amine oxide.
