Abstract
The invention discloses a synergism weeding composition. The composition is composed of 2-(6-fluorine-pyridine acyloxy)-N-(4-fluorophenyl)-N-(1-methyl ethyl), thioacetamide (TAM-5) and atrazine serving as effective constituents and auxiliary elements, wherein the auxiliary elements can be accepted in pesticides, and the weight ratio of the TAM-5 to the atrazine is 50:1-1:100. The two effective constituents form synergism after being combined, and herbicide controlling spectrums can be enlarged; meanwhile, antagonism does not exist, and safety for crops is improved. The synergism weeding composition can effectively prevent and remove annual grassy weeds and broadleaf weeds, can also restrain part of perennial weeds, can be used for weeding on bare places and farmlands such as corn fields, sugarcane fields, oilseed rape fields and tea gardens, remarkably improves weeding effects and lowers the cost.
Description
Technical field
The present invention relates to a kind of weeding class composition pesticide, especially for farmland and uncultivated area weedings such as sugarcane field, corn field, Rapeseed Field, tea places.
Background technology
The farmland such as sugarcane field, corn field, Rapeseed Field, tea place and uncultivated area weeding have numerous weeds.For common corn field weed, there are barnyard grass, lady's-grass, piemarker, Amaranthus retroflexus, eleusine indica, india lovegrass, green green bristlegrass, setaria glauca etc.In corn field common weed, not only raw weeds also have perennial weed one year, and these weeds have multiple go out grass the phase, difficulty of prevention and cure is large.Easily there is poisoning in the glyphosate the most often used in current agricultural production, careless ammonium phosphine, Acetochlor, Bi Kecao etc.To requiring high the careless age of weeds during most of aforementioned Common Herbicides dispenser simultaneously, exceed the careless age of certain limit, herbicidal effect obviously reduces.Glyphosate, careless ammonium phosphine class weed killer herbicide is only applicable to uncultivated area weeding.

tAMcompound in
tAM-5(formula 2) activity of weeding is best, can effectively prevent and kill off annual grassy weed and broad leaved weed, but can only play limited inhibition to part perennial weed, and herbicide spectrum is extensive not.
Atrazine belongs to triazine herbicide family, has become in late nineteen nineties in last century the weed killer herbicide that the U.S. comparatively commonly uses.Atrazine chemical name is the chloro-4-diethylin of 2--6-isopropylamine base-1,3,5-triazines, and its structural formula as shown in Equation 3.Other common name of atrazine also have: atrazine, Aatrex, Primatola etc.Atrazine is a kind of systemic herbicide, absorbs and upwards conduct mainly through plant root, suppresses the photosynthesis of weeds (as cocklebur, foxtail, Ambrosia plant and wild cucumber etc.), makes it withered.May be used for weeding before seedling, also may be used for postemergence weed control.The absorption of atrazine is based on root absorption, and cauline leaf absorbs seldom.Widely using at corn field etc., because atrazine is in the resistance crop bodies such as corn, can be resolved into innocuous substance by corn ketolase, is thus safe to corn crop.Atrazine can prevent and kill off multiple annual gramineae and broad leaved weed.Be applicable to the dry crops such as corn, Chinese sorghum, sugarcane, fruit tree, nursery, forest land and prevent and kill off lady's-grass, barnyard grass, green foxtail, nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae, pulse family weeds, especially there is good selectivity (because there being the corn ketolase of removing toxic substances in Corn) to corn, also having certain inhibitory action to some perennial weed.Use middle arid to wield influence to drug effect comparatively large, mainly act on dicotyledon, stress to close, the weeds effect large to careless age is undesirable.
Summary of the invention
For above-mentioned situation, report one can effectively be prevented and kill off annual grassy weed and broad leaved weed by the present invention, efficient, the safe weeding agricultural chemicals of part perennial weed can be suppressed again, may be used for farmland and the uncultivated area weedings such as corn field, sugarcane field, Rapeseed Field, tea place.

Can be shown by following experiment, two active ingredients in above-mentioned Herbicidal combinations of the present invention
tAM-5 and the composite of atrazine can have obvious synergistic effect.
In the research of weed killer herbicide, when the activity of weeding after active compound exceed that each reactive compound uses separately active time, then show to there is synergistic effect.
The budget activity of the given combination of two kinds of weed killer herbicides can be calculated as follows (bibliography: author Colby, S.R. etc., periodical title " Weed ", 1 phase in 1967, P20-22)
When X=% is when amount of application is p kg/ha, weed killer herbicide A (reactive compound A) loss ratio,
And Y=% is when amount of application is q kg/ha, weed killer herbicide B (reactive compound B) loss ratio,
And E=% is when amount of application is p and q kg/ha, the speculative damage rate of weed killer herbicide A and B, then:
E=X+Y-X*Y/100
If actual damage value exceedes calculated value, the activity of composition be super add and, namely show synergy.
One, potted plant experiment

tAM-5) wetting powder (WP) (preparing according to the embodiment of the present invention 18), 30% atrazine suspending agent (SC) (preparing according to the embodiment of the present invention 19) and the composite rear indoor virulence experimental result to grassy weed and broad leaved weed (Amaranthus retroflexus 2-4 leaf phase, eleusine indica 2-4 leaf phase), as shown in Table 1.
The activity of weeding effect of table one potted plant experiment
Table 1 experimental result shows, reactive compound (
tAM-5), after composite with atrazine two kinds of compositions, there is notable synergistic effect.
Two, field efficacy experiment
In live corn 2 ~ 3 leaf phase, weeds 2 ~ 4 leaf phase, reactive compound with 40% (
tAM-5) wetting powder (WP) (preparing according to the embodiment of the present invention 18), the atrazine suspending agent (SC) (preparing according to the embodiment of the present invention 19) of 30% and the Herbicidal combinations of 40%
tAM-5 atrazine wetting powder (WP) (preparing according to the embodiment of the present invention 15) effect experiments to corn field weed.After medicine 30 days investigation fresh weight preventive effects and 5% significance level as shown in table 2.
The field test results of table 2 Control Weeds in Maize Field
The experimental result display of table 2, in the present composition
tAM-5 composite with atrazine, can form synergistic effect, and can expand herbicide spectrum, simultaneously without antagonism, to crop safety raising, significantly improve herbicidal effect, reduce cost.
