Abstract
The invention relates to a herbicide composition containing metolachlor. The herbicide composition contains three active ingredients, namely metolachlor, pyrazosulfuron-ethyl and clomazone, wherein the weight ratio of metolachlor to pyrazosulfuron-ethyl to clomazone is (5-50): (1-20): (1-20). The herbicide composition provided by the invention has the advantages of safety, high speed, broad weed control spectrum, long drug applying period and little environmental influence.
Description
Technical field
The present invention relates to a kind of herbicidal composition that contains isopropyl methoxalamine.
Background technology
Paddy rice is the important cereal crops of China, concerning the grain security of national economy and country.Direct-seeding Rice is easy because sowing, save labor cost, add that output is high, develop very fast, but can not ignore its three Risks.1, the rotten kind of low temperature in early spring: early spring, temperature was higher, is conducive to Direct-seeding Rice growth, seldom occurs rotten kind of phenomenon.2, weeds risk: Direct-seeding Rice land for growing field crops rice breeding time than modes such as transplanting long 20 my god, cause weeds harm time long, add that field Guan Shui makes soaked with sweat alternately, barnyard grass, moleplant seed are grown vigorous.Therefore need twice weeding, for the first time more live rear 2-4 days or rice shoot two leaves wholeheartedly after, mainly prevent and kill off the monocotyledon weed such as barnyard grass, moleplant seed; At live latter about 20 days, mainly prevent and kill off broad leaved weed for the second time.3, lodging tolerance is not strong; Direct-seeding Rice root system is shallow, and its lodging tolerance is weaker than transplant field.
Isopropyl methoxalamine mainly absorbs by young shoot, and upwards conduction, suppresses the growth of young shoot and root.The protein of the main sprout inhibition seed of mechanism of action is synthetic, secondly suppresses choline and infiltrates phosphatide, disturbs lecithin to form.Due to grassy weed young shoot, to absorb the energy force rate broad leaved weed of isopropyl methoxalamine strong, thereby the effect that this medicine is prevented and kill off grassy weed is better than broad leaved weed far away.
Pyrazosulfuron, english common name: pyrazosulfuron-ethyl, chemical name: 5-(4,6-dimethoxypyridin base-2-carbamyl sulfonamides)-1-methylpyrazole base-4-Ethyl formate.Pyrazosulfuron belongs to a kind of efficient sulfonylurea optional water field herbicidal.In water, diffusion rapidly, is transmitted to after the root absorption of weeds in plant body, hindered aminoacid synthetic.Promptly suppress the growth of weeds leaves and stems and the stretching, extension of root, then completely withered.To rice safety.Herbicide spectrum is wider, better to control efficiency such as broad leaved weed, sedge weed, barnyard grasses.Not temperature influence of its drug effect, lasting medicine, disposable employed, can control the multiple weeds harm of rice growing season.
Clomazone, english common name: clomazone, chemical name: 2-(2-chlorobenzyl)-4,4-dimethyl isoxazole-3-ketone.Clomazone belongs to selectivity preemergence herbicide, can control the chlorophyllous biosynthesis of sensitive plant after being absorbed, and makes plant dead in a short time.Have moderate cohesive with soil, in soil mainly by microbial degradation.
When isopropyl methoxalamine, pyrazosulfuron, the single use of clomazone, all there are certain defect and limitation.Weed killer herbicide is reasonable composite is to improve preventive effect, expansion herbicide spectrum, delays the speed of shift of weed community, alleviates the pollution to environment, reduces a kind of effective ways of use cost and reduction herbicide residue.
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 herbicidal composition is efficiently provided.
solution
In order to solve the problems of the technologies described above, the invention provides a kind of herbicidal composition that contains isopropyl methoxalamine, it is characterized in that, described herbicidal composition comprises isopropyl methoxalamine, three kinds of active components of pyrazosulfuron, clomazone, and wherein the weight ratio of isopropyl methoxalamine, pyrazosulfuron, clomazone is 5～50:1～20:1～20.
Preferably, the weight ratio of isopropyl methoxalamine, pyrazosulfuron, clomazone is 20:1:1.
Preferably, the mass percent of described active component in herbicidal composition is 5-70%.
Preferably, described combination dosage form is wetting powder.
Wetting powder is made up of active component, wetting agent, dispersant, filler etc.
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
All the other are auxiliary agent.
Inventor's discovery, this formula adopts the effect of wetting powder better.
Wetting powder WP (Wettable Powder) definition: the powderous preparations that dispersibles Yu Shuizhong formation stable suspension.
Wetting powder (WP) is with pesticide original medicine, inert filler and a certain amount of auxiliary agent, after abundant co-grinding, reaches the formulation of certain particle size in proportion.From in shape, with pulvis indistinction, but owing to having added the auxiliary agent such as wetting agent, dispersant, can be moistening by water after being added in water, disperse, form suspension, can spray and use.Compared with missible oil, wetting powder production cost is low, available paper bag or plastic bag packaging, and accumulating is convenient, safety, and packaging material ratio is easier to process; The more important thing is, wetting powder does not use solvent and emulsifier, safer to plant, is difficult for producing poisoning, environmentally safe, before fruit bagging, uses, and can avoid the stimulation of organic solvent to fruit face.
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.
