Abstract
The invention relates to a weedicide composition formed by using pyribenzoxim and diflufenican as main ingredients and adding addition agent as well as carrier water. The composition has the advantages of special effects on preventing and eliminating weeds in wheat fields, broad weeds eliminating spectrum, good effects on preventing and eliminating various weeds, safety to current and afterreap crops, simple processing technique, no three wastes and convenient use.
Description
(1) technical field
The invention belongs to pesticide field, relate to a kind of herbicidal composition.
(2) background technology
Preventing and kill off of wheat weeds is the key of wheat class good harvest high yield, and China's wheat planting area is very big, and preventing and kill off of wheat weeds is extremely important.Because the variation of field ecosystem and weeds pesticide resistance strengthen, wheat weeds had become the main harm of Wheat Production in recent years.The chemical agent that is used for control of weed in wheat field at present mainly contains 60% butachlor suspending agent, 40% oat fear missible oil, 36% diclofop-methyl missible oil, 6.9% galloping horse emulsifiable concentrate, 72%2,4-d butyl ester missible oil, the clean dry suspending agent of 75% broad-leaved, 48% benzene reach and send suspending agent etc., these medicaments are because long-term the repetition or not science use, make that the wheat weeds resistance is serious, dosage increases, and raises thereby cause preventing and treating cost.
(3) summary of the invention
The purpose of this invention is to provide a kind of efficient, low toxicity, weed killer herbicide agent agricultural chemicals safe in utilization.
A kind of herbicidal composition provided by the invention is the suspending agent that is processed through certain production technology by pyribenzoxim, fluorine metazachlor, auxiliary agent and carrier water.
The pyribenzoxim chemical constitution is as follows:
Belong to acetolactate synthestase (ALS) inhibitor, selectivity efficient pyrimidine ether weed killer herbicide, be mainly used in numerous grass family in crop field and broad leaved weeds such as preventing and kill off paddy rice, wheat, can be used for preventing and kill off amur foxtail, green foxtail, lady's-grass, field bindweed, annual bluegrass, moleplant seed, kitchen garden, black nightshade, needle spikesedge herb, clearvers, Siberian cocklebur, chickweed, barnyard grass grass, special-shaped nutgrass flatsedge, cyperus iria, purple water amaranth, big lady's-grass, Sagittaria pygmaea etc.; Using dosage 30～45g (a.i.)/hm
2Pure product pyribenzoxim is a white solid, m.p.128～130 ℃, dissolubility (25 ℃, mg/l): water 3.5.The acute LD of pyribenzoxim
50(mg/kg): rat oral〉5000 (female); Through the skin mouse〉2000; To rabbit skin and eyes nonirritant; Animal there are not teratogenesis, mutagenesis, carcinogenesis.
Fluorine metazachlor chemical constitution is as follows:
Belong to carotenoid biosynthesis inhibitor, be applicable to and prevent and kill off broad leaved weed such as Veronica, clearvers, benbie, lamb's-quarters, shepherd's purse, big pawl dish, field viola etc., mu consumption 3.3g (a.i.) behind the wheatland seedling in early days.Pure product fluorine metazachlor is a clear crystal, m.p.107.2～107.6 ℃; Dissolubility (20 ℃, g/l): be insoluble in water, ethyl acetate 464, acetone 557, carrene 764, methyl alcohol 30.4.The acute LD of the former medicine of fluorine metazachlor
50(mg/kg): rat oral〉5000; Through skin〉4000; To rabbit skin and eyes nonirritant; With the 2.7mg/kgd dosage rat of feeding, no abnormal phenomenon.
The inventor measures through test of many times, and pyribenzoxim and fluorine metazachlor are composite by a certain percentage, and under the specific adjuvant effect, herbicidal composition provided by the invention is (every 666.7m under recommended dose
2Consumption 100.0 grams～150.0 grams), 30 days field control effects to all kinds of weeds of wheat paddock are 88%～98% after the dispenser.Auxiliary agent is necessary composition, and water plays carrier function.
Pyribenzoxim and fluorine metazachlor are composite according to a certain percentage to be one of key character of the present invention.
Preferred proportioning components is:
Composition percentage by weight (%)
Pyribenzoxim 5.0～30.0
Fluorine metazachlor 5.0～30.0
Auxiliary agent 5.0～10.0
Carrier water 30.0～85.0
Best proportioning is:
Composition percentage by weight (%)
Pyribenzoxim 10.0～25.0
Fluorine metazachlor 10.0～25.0
Auxiliary agent 5.0～10.0
Carrier water 40.0～65.0
Production technology of the present invention: pyribenzoxim and fluorine metazachlor are mixed under stirring condition, add auxiliary agent and carrier water in proportion, grind repeatedly through sand mill, 98% above particle diameter＜5 μ m is packed on request after being up to the standards and is product.
The present invention is used to prevent and kill off all kinds of weeds of wheatland can obtain good effect.
Advantage of the present invention is:
1. enlarge and kill the grass spectrum, cornfield gramineae weed and broad leaved weed are all had good control efficiency, disposable dispenser can be controlled various weeds in the wheatland whole growing, and preparation is recommending all kinds of weeds effects of consumption wheat paddock to reach 88%～98%.
2. to working as stubble wheat and succession crop safety, the herbicidal composition formulation rate that the present invention proposes is little, the control cost is low, and all safe to the various crops of back batch plantation after the medication.
3. technology is simple, and the raw material of input all is converted into product, yield height, the no three wastes.
(4) embodiment
Below the invention will be further described with embodiment:
Composition percentage by weight (%)
Pyribenzoxim 12.0
Fluorine metazachlor 13.0
Auxiliary agent 8.0
Carrier water 77.0
Claims (4)
1. a herbicidal composition is characterized in that with pyribenzoxim and fluorine metazachlor be Main Ingredients and Appearance, and adding assistant, water are processed formulated.
2. herbicidal composition according to claim 1 is characterized in that its composition and percentage by weight are as follows:
Composition percentage by weight (%)
Pyribenzoxim 5.0～30.0
Fluorine metazachlor 5.0～30.0
Auxiliary agent 5.0～10.0
Carrier water 30.0～85.0
3. herbicidal composition according to claim 1 is characterized in that the part by weight between pyribenzoxim and the fluorine metazachlor is (1.0～1.5): 1.0.
4. herbicidal composition according to claim 1 is characterized in that said composition is used for wheat weeds.
