Abstract
The invention discloses a kind of Herbicidal composition for rice field, is related to pesticide herbicide technical field, is made up of active ingredient and auxiliary agent；Wherein, it is 1 ~ 30 that active ingredient You metamifops, Bentazon, pyribenzoxim, which combine , metamifops, Bentazon, the mass ratio of pyribenzoxim,：1~50：1~30；Composition can be configured to oil-suspending agent, water dispersible granules, wettable powder.Herbicidal combinations of the present invention use in rice terrace, are a kind of low amounts highy potent herbicides for preventing and treating rice terrace broad leaved weed and grassy weed, have the characteristics of cost is low, and herbicidal spectrum is wide, and the lasting period is long.
Description
Technical field
The present invention relates to pesticide herbicide technical field, in particular to a kind of Herbicidal composition for rice field.
Background technology
About 4.5 hundred million mu of China's Monitoring of Paddy Rice Plant Area, about 2.9 hundred million mu of weeds in paddy field occurring area, occurring area rate are
64.5%.20 Duo Ge sections belong to more than the 150 individual names of an article to China's weeds in paddy field altogether, and the anti-weeds species of main hardly possible in paddy field is more and more, such as
Turn into advantage in weeds such as each rice producing region in the whole nation, barnyard grass, Paspalum distichum, rice Leersia Sw, Weedy Rice, Creeping bentgrass in recent years
Malignant weed.Because the change of tillage and cultivation mode, such as increase year by year of direct seading rice area, particularly dry direct-seeding rice area increase
Greatly, it is currently to eliminate the outstanding problem in production practices that upland field weed, which enters paddy field, such as lady's-grass, eleusine indica, green bristlegrass, moleplant seed
Deng.
In recent years, different types of herbicide is subjected to Synergistic, expands herbicide controlling spectrum, to obtain than single herbicide more
Have become common technical scheme for excellent characteristic.
It is several frequently seen herbicide below：
Metamifop（Metamifop）It is the aryloxyphenoxypropanoates class herbicide developed by Chemical Engineering Technology research institute of South Korea,
Most of annual gramineous weeds can be prevented and kill off, unlike most of such herbicides , metamifops to rice safety,
Rice terrace main weeds can be effectively prevented and kill off, such as barnyard grass, lady's-grass, moleplant seed and eleusine indica, is mainly used in live and transplanting rice field and removes
Grass.
Bentazon, is a kind of broad spectrum activity killing type herbicide after seedling, and its active ingredient is mainly absorbed by the blade of weeds
And conduction, mainly absorbed in dry land by the cauline leaf of weeds seedling, and used in paddy field, it can be permeated by blade and blade tip,
And can is inhaled by root.
Pyribenzoxim（Pyribenzoxim）, O-（2,6- is double（4,6- dimethoxypyridin -2- base epoxides）Benzoyl）
Oxime benzophenone, novel oxime ester compound, wide spectrum selective post-emergence herbicide, belong to acetolactate synthestase（ALS）Suppression
Preparation.There is activity of weeding after selective ultra high efficiency bud to rice, common wheat, Korea lawn grass, for preventing and kill off barnyard grass, amur foxtail etc.
Various grassy weeds and broad leaved weed have notable drug effect.
Application publication number is that the A of CN 102113503 Chinese invention patent discloses a kind of herbicide for rice terrace
Composition, active component is by metamifop with bensulfuron-methyl, than Sulfometuron Methyl, two chloroquine phosphoric acid, Bentazon, bispyribac-sodium, diformazan
Any one in tetrachloro penoxsuam and azoles humulone or two kinds of compositions, are consequently formed Second Academy's herbicide or ternary herbicide group
Compound, a variety of grassy weeds in rice terrace disposably can be effectively prevented and kill off, have special efficacy to the difficult anti-weeds of direct sowing rice field.
Common weeds mainly have grassy weed and the class of broad leaved weed two in rice terrace, and a kind of herbicide has been used alone
Through can not effectively control the generation of weeds, in order to expand herbicide controlling spectrum, eliminate weeds and ensure the safety of crop, extend dispenser and fit
Phase and cost is reduced, the application is developed to the Herbicidal combinations using above-mentioned three kinds of herbicides as core component.
The content of the invention
Present invention aim to provide a kind of Herbicidal composition for rice field, the grass family main for preventing and treating rice terrace
Weeds and broad leaved weed, increase herbicidal spectrum, and reach and reduce Pesticide use amount with application times with cost-effective purpose.
A kind of Herbicidal composition for rice field, is made up of active ingredient and auxiliary agent；
Wherein, active ingredient You metamifops, Bentazon, pyribenzoxim combine , metamifops, Bentazon, phonetic
