In above embodiment, proportioning is weight per distribution ratio.
In above-mentioned example of formulations 1-embodiment 19, individually disclose the present invention using component (a), component (b) and component (c) different dosage form as the weed killer herbicide of active ingredient, but the present invention is not limited to above-described embodiment, in the embodiment that other are feasible, in composition, the proportioning of each chemical composition, working condition all can change.
In order to embody the weed control efficacy of weed killer herbicide of the present invention better, be described below with reference to specific experiment data.
Biological Examples
When the effect of weed killer herbicide exceedes the summation of the effect when each component is used separately, there is synergistic function.The predictive role of the particular combination of two kinds of components can use so-called " Colby formula " (see S.R.Colby, " CalculatingSynergisticandAntagonisticResponsesofHerbicid eCombinations ", Weeds1967,15,20 ~ 22) calculate as follows: if
A is the activity when using the reactive compound A that consumption is mppm for mg/ha or concentration;
B is the activity when using the reactive compound B that consumption is nppm for ng/ha or concentration, is expressed as the percentage accounting for untreated control;
C is the activity when using the reactive compound C that consumption is hppm for hg/ha or concentration, is expressed as the percentage accounting for untreated control;
E is when use consumption for m, n, hg/ha or concentration are the reactive compound A of m, n, hppm, and expection activity during C,
N is 3;
If the activity of actual observation (O) is greater than expection active (E), so said composition super add and, namely there is synergistic effect.
Inventor is by a large amount of screening tests, lot of experiments and preventive effect analysis have been carried out to the different ratio of component (a), component (b) and component (c), find in certain ratio range, the Herbicidal combinations obtained has synergistic effect, and be not only the simple addition of three kinds of medicaments, be illustrated with following biologicall test example.
test before seedling:
Under greenhouse experiment, test plant is seeded in seedling alms bowl.Use standard soil as cultivation matrix.In the seedling last stage, weed killer herbicide is administered to soil surface separately or as a mixture.Consumption depends on determined optium concentration under field or greenhouse experiment.In post-evaluation in 2 ~ 4 weeks test, (100% effect=plant is completely dead; 0% effect=plant-less toxicity effect).Component (a), component (b) and component (c) combination table reveal than using separately better preventive effect in this test, show obvious synergistic effect.
When weed killer herbicide of the present invention is used before rudiment, can prevent weeds from emerging completely or then weed growth to cotyledon period stops growing and completely dead after 3 ~ 4 weeks.
Test after seedling:
Test: carry out Herbicidal Testing Trials for dissimilar weeds (eleusine indica, barnyard grass, eleusine indica, lady's-grass, green foxtail, lamb's-quarters, Amaranthus retroflexus, acalypha copperleaf, clearvers, knotweed).
Test method: load the corn field soil that the degree of depth is about 8cm in seedling alms bowl (diameter 8cm × degree of depth 12cm), to add water in this basin and in addition smooth, left standstill three days, the depth of 0.5cm is being about, sowing eleusine indica, barnyard grass, eleusine indica, lady's-grass, green foxtail, lamb's-quarters, Amaranthus retroflexus, acalypha copperleaf, clearvers, knotweed apart from soil surface.Add water till the degree of depth apart from soil surface 3cm.One period of predetermined time is planted under irrigation conditions.When plant reached for 3 ~ 4 leaf stage, transferred to by the seedling alms bowl of the predetermined number growing plant in a square plastic basin, being filled to wherein is highly 3cm.In the test plants using back type sprayer to be administered to separately or as a mixture by weed killer herbicide to be under water saturation soil condition.Consumption depends on determined optium concentration under field condition.(100% effect=plant is completely dead in chemical treatment post-evaluation in 3 ~ 5 weeks test; 0% effect=plant-less toxicity effect).The mixture used in this test shows good result.
Three kinds of reagent are prepared: 1, component (a) according to constant weight percentage; 2, component (b); 3, component (c); 4, component (a)+component (b)+component (c).Afterwards by above-mentioned each reagent dilute with water, obtain medicament dilution.After the medicament dilution process regular hour, observe the herbicidal effect to eleusine indica, barnyard grass, eleusine indica, lady's-grass, green foxtail, lamb's-quarters, Amaranthus retroflexus, acalypha copperleaf, clearvers, knotweed respectively.
The herbicidal effect to barnyard grass is observed after process surrounding
Herbicidal effect to eleusine indica after process surrounding
Herbicidal effect to green foxtail after process surrounding
Herbicidal effect to lamb's-quarters after process surrounding
Herbicidal effect to Amaranthus retroflexus after process surrounding
Herbicidal effect to clearvers after process surrounding
Herbicidal effect to lady's-grass after process surrounding
Herbicidal effect to acalypha copperleaf after process surrounding
Can find out according to result of the test, the herbicidal effect of the weed killer herbicide of component (a)+component (b)+component (c) obviously adopts more separately component (a), component (b) or component (c) better, possess obvious gain effect, and keep higher activity of weeding under the active ingredient of low usage amount; In addition, three kinds of herbicidal constituents are comparatively used separately in wherein any one composition, have wider herbicide spectrum.
Composition of the present invention and class methods be described by specific embodiment.Those skilled in the art can use for reference the links such as the suitable feed change of content of the present invention, process conditions and realize other objects corresponding, its relevant change does not all depart from content of the present invention, similar replacement and change be all deemed to be included within scope of the present invention so will become apparent to those skilled in the art that.
