Abstract
The invention provides a weeding composition for a paddy field. The weeding composition comprises an ingredient A and an ingredient B, wherein the ingredient A is iodosulfuron-methyl sodium, the ingredient B is propisochlor, and the weeding composition is formed through compounding the ingredient A and the ingredient B. According to the weeding composition for the paddy field, due to the adoption of the scheme, the composition of the ingredient A and the ingredient B has a synergistic role and has a good prevention and elimination effect on the weeds of the grass family, broad-leaved class and sedge family in the paddy field; and the residual life is short, and then, the growth of next crops is not affected, so that the composition is environment-friendly.
Description
Technical field
The present invention relates to the paddy field weeding technical field, refer in particular to a kind of Herbicidal composition for paddy fields.
Background technology
Iodosulfuron methyl sodium is good to broad leaved weed and sedge weed control efficiency, but in the rice field except above-mentioned two class weeds, also have grassy weeds such as barnyard grass grass, moleplant seed simultaneously.Therefore, the weed killer herbicide that is used alone composition can't reach the purpose of comprehensive weeding.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of Herbicidal composition for paddy fields that can comprehensive weeding is provided.
For achieving the above object, technical scheme provided by the present invention is: a kind of Herbicidal composition for paddy fields, and it includes component A and B component, and wherein, component A is iodosulfuron methyl sodium, and its structural formula is:
One or multinomial composite formation Herbicidal combinations in component A and the B component; B component is alachlor, isopropyl methoxalamine, propisochlor, Acetochlor, the third careless amine, butachlor, mefenacet, dichloro quinolinic acid, cyhalofop-butyl, pendimethalin, anilofos, two careless ether, pyribenzoxim, pyriftalid and KIH 6127.
Be added with safener in the composition of described A and B.
The weight ratio of described component A and B component is 1:0.5 ~ 1:1000.
The effective ingredient of described component A (a.i.) usage amount be every public affairs incline 1 ~ 20 the gram.
The present invention is after having adopted such scheme, and the composition of component A and B component has the effect of Synergistic, both to the rice field grassy weed, also broad-leaved class and sedge weed there is good preventive effect, and the longevity of residure is short, does not influence a following batch thing and grows, and is environmentally friendly.
Embodiment
Below the invention will be further described, preferred embodiment of the present invention is: the described Herbicidal composition for paddy fields of present embodiment includes component A and B component, wherein, component A is iodosulfuron methyl sodium (4-iodo-2[3-C4-methoxy an aromatic plant metioned in ancient books-6-formaldehyde-1.3.5-triazine-2-an aromatic plant metioned in ancient books) urea an aromatic plant metioned in ancient books sulfonyl] methyl benzoate, sodium salt; B component is alachlor B1, isopropyl methoxalamine B2, propisochlor B3, Acetochlor B4, the third careless amine B5, butachlor B6, mefenacet B7, dichloro quinolinic acid B8, cyhalofop-butyl B9, pendimethalin B10, anilofos B11, two careless ether B12, pyribenzoxim B13, pyriftalid B14 and KIH 6127 B15.One or multinomial composite back adding auxiliary agent in component A and the B component, also can add safener as required again, adopt common pesticidal preparations process technology to carry out preparation processing production then, make forms such as wetting powder, water dispersible granules (tablet), effervescent tablet, big granula, missible oil, microemulsion, aqueous emulsion, suspending agent, oil-suspending agent; Wherein, weight proportion such as the table one of component A and B component:
Table one:
According to the proportioning in the last table choose different formulations in Ya Gu village, Louxing District Wan Bao town, Hunan, a plurality of areas such as new peace 2 villages, the new town of Longjing City, Jilin Province intelligence have carried out field plot trial, in rice transplanting dispenser after 4 days, 20 days " Invest, Then Investigate " herbicidal effects of dispenser, the consumption proportion of its A and B and application effect are:
When component A consumption is lower, it is 1.5 grams when (a.i.) that every public affairs are inclined, the usage amount of B component and control efficiency such as table two:
Table two:
Analyze from table two and to draw, fine to the grassy weed control efficiency when adopting the higher weight ratio of B component in the table one again when component A is that 1.5 gram (a.i.)/public affairs are inclined, but general to nutgrass flatsedge, broad leaved weed control efficiency.
Medium when component A consumption, every public affairs are inclined when being 7.5 grams (a.i.), the usage amount of B component and control efficiency such as table three:
Table three:
Analyze from table three and to draw, when component A is that 7.5 gram (a.i.)/public affairs are inclined, adopt again when the B component adopts the weight ratio of medium consumption in the table one, all fine to grassy weed, nutgrass flatsedge and broad leaved weed control efficiency, reached the purpose of comprehensive weeding.
Higher when component A consumption, every public affairs are inclined when being 15 grams (a.i.), the usage amount of B component and control efficiency such as table four:
Table four
Analyze from table four and to draw, general to the grassy weed control efficiency when adopting the weight ratio that the B amounts of components is lower in the table one again when component A is that 15 gram (a.i.)/public affairs are inclined, but fine to nutgrass flatsedge, broad leaved weed control efficiency.
From experimental result, the weight proportion in the preferred table three can reach the purpose of comprehensive weeding.
The embodiment of the above only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, so the variation that all forms according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
