Abstract
The invention relates to a synergic weeding composition containing foramsulfuron and second active ingredients. The second active ingredients are one or more ingredients selected from terbuthylazine, atrazine and nicosulfuron. The weight ratio between the foramsulfuron and the second active ingredients ranges from 20:1 to 1:30. By means of the weeding composition, various weeds such as crab grass, green bristlegrass, lamb's-quarters, piemarker, smartweed, barnyard grass, acalypha australis and nightshade in a corn field can be prevented and controlled. The weeding composition has an obvious synergistic interaction effect, and the prevention and control effect of farm chemical is improved; the dosage of the farm chemical is decreased, the use cost is reduced, the environmental pollution is alleviated, and the social benefits are achieved.
Description
Technical field
The present invention relates to pesticide field, particularly weed killer herbicide field, relate to a kind of Herbicidal combinations containing formamido group Sulfometuron Methyl particularly, said composition can be used for corn field.
Technical background
Corn is the important cereal crops of China, and be also important forage crop and the raw material of industry, along with the development of the industries such as livestock breeding, food processing industry, wine-making industry and biodiesel, the market demand of corn constantly increases simultaneously.The weeds of corn field occur general, of a great variety, when Maize Seedling is by Weed infestation, plant is short and small, and bar spire is yellow, causes middle and later periods corn growth bad, Severe Reduction, therefore, the chemical control of corn field weed after broadcasting before seedling and after seedling early stage two critical periods carry out.
Formamido group Sulfometuron Methyl is a kind of sulfonylurea weed killer herbicide, can prevent and kill off many important grassy weed and the broad leaved weed in Major Maize producing region, the world, to rear stubble rotation crop and environment all very safe.But poor to the preventive effect of part grassy weed and broad leaved weed, when the weeds such as lady's-grass, green foxtail, lamb's-quarters grass age is less, control efficiency is fine, but when grass age is larger, even if strengthen using dosage, can not management of weeds well.
Garagard (Terbuthylazine) and atrazine (Atrazine) are triazine herbicide.Herbicide spectrum is comparatively wide, can prevent and kill off multiple annual gramineae and broad leaved weed, to the preventive effect of broadleaved herb apparently higher than grassy weed.
Summary of the invention
The object of the invention is to overcome prior art defect, provide a kind of and expand herbicidal spectrum, there is synergistic effect and the low Herbicidal combinations containing formamido group Sulfometuron Methyl of cost, be applicable to the multiple weeds in control of maize field.
To achieve these goals, the invention provides a kind of Synergistic herbicide compositions, described Herbicidal combinations contains formamido group Sulfometuron Methyl and the second active component, second active component be selected from Garagard, atrazine or nicosulfuron one or more, wherein, the weight ratio of formamido group Sulfometuron Methyl and the second active component is 20:1-1:30.
Preferably, the weight ratio of formamido group Sulfometuron Methyl and the second active component is 5:1-1:5.

Biological examples
Toxicity Determination:
Theoretical fresh weight inhibition (the E of each treatment combination is calculated by Gowing method
0=x+y-x × y/100), then compared with actual measurement inhibiting rate (E), the mixed synergy type to weeds of both evaluations, works as E-E
0value > 10% is synergistic effect, E-E
0value < 10% is antagonism, E-E
0value is addition between-10% and 10%.
In formula, X is formamido group Sulfometuron Methyl consumption is the fresh weight inhibition that P is; The fresh weight inhibition that Y is the second active component consumption when being Q.
The composite rear effect to weeds of table 1
As can be seen from data in table 1, formamido group Sulfometuron Methyl and the composite rear E-E of Garagard, atrazine or nicosulfuron
0value is all greater than 10%, has obvious synergistic effect as seen to control lady's-grass, acalypha copperleaf.
Field trial:
The composite rear control efficiency to weeds in field of table 2
By the data of table 2 can find out formamido group Sulfometuron Methyl and Garagard, atrazine or nicosulfuron composite after, to the preventive effect of different weeds, all have obvious synergistic effect.
Cornfield weeding composition of the present invention is described by concrete example, those skilled in the art can use for reference content of the present invention, the links such as suitable feed change, process conditions realize other object corresponding, its relevant change does not all depart from content of the present invention, all similar replacements and change will become apparent to those skilled in the art that and be all deemed to be included within scope of the present invention.
