Biological test example
When the effect of active compound combinations exceedes the summation of the effect when each reactive compound is used separately, there is synergistic function.The predictive role of the particular combination of two kinds of reactive compounds can use so-called " Colby formula " (see S.R. Colby, " Calculating Synergistic and Antagonistic Responses of Herbicide Combinations ", Weeds 1967,15,20-22) calculate as follows: if
X is the activity when using the reactive compound A that consumption is mppm for mg/ha or concentration;
Y 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;
E is when using consumption for activity during m and n g/ha or the concentration reactive compound A and B that is m and n ppm,
So
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, the different ratio of the compound (A) related in the present invention and the various combination of (B) has carried out a large amount of tests and effectiveness analysis, find in certain ratio range, the Herbicidal combinations obtained has gain effect, and is not only the simple addition of two kinds of medicaments.
1. control of weeds before seedling
Seed or the rhizome of unifacial leaf and dicotyledonous harmful plants is put in the cardboard basin that sandy loam is housed, and good with earth mulch.To make concentrated aqueous solution, the composition of wetting powder or missible oil form applies it to soil cover surface with various dosage.After process, basin to be placed in greenhouse and under making weeds remain on better growing conditions.After test plants emerges after test 3-4 week, compare with untreated control, visually observe record plant injury situation or to the adverse effect of emerging.As shown in result of the test, the present composition, at preemergence application, has good activity of weeding to the unifacial leaf of wide spectrum and broadleaf weed.
2. postemergence weed control effect
Seed or the rhizome of unifacial leaf and dicotyledonous harmful plants is put in the cardboard basin that sandy loam is housed, good and cultivate in the greenhouse of excellent growing conditions with earth mulch.After sowing 3 weeks, in tri-leaf period by present composition process test plants.Keep test plants in the greenhouse under the best growing condition after about 3-4 week, compared with untreated control, the activity of naked eyes record preparation.During postemergence application, the present composition also has good activity of weeding to the important grass family of the economy of wide spectrum and broad-leaved section weeds.
The active active summation exceeded when weed killer herbicide is used alone of the present composition can be observed frequently.The result of the test of observing shows, under suitable low dosage, the activity of composition has exceeded the desired value according to Colby formulae discovery.
3. the tolerance (field trial) of activity of weeding and crop
Under the non-transgenic cole crop of anti-sulfonylurea herbicide is planted in outdoor natural conditions together with typical weeds.On the other hand, the weed population naturally-occurring when rapeseed plant grows.After seedling, the 2-4 leaf phase is to weeds process.In order to embody synergistic effect, to process lower than actual application dosage.
Table 1 processes the activity of weeding to datura after surrounding
Table 2 processes the activity of weeding to green foxtail after surrounding
Table 3 processes the activity of weeding to clearvers after surrounding
Table 4 processes the activity of weeding to chickweed after surrounding
Table 5 processes the activity of weeding to amur foxtail after surrounding
Can find out according to result of the test, the herbicidal effect of compd A and compd B obviously adopt more separately compd A or compd B better, possess obvious gain effect, and keep higher activity of weeding under the active ingredient of low usage amount.In addition, two kinds of herbicidal constituents are comparatively used separately in wherein any one composition, have wider herbicide spectrum, and this composition possess the characteristic of low toxicity, low-residual, significantly improves the control efficiency to weeds in crop growth environment.This experiment is also observed, and resistance cole crop is not injured after with Synergistic herbicide compositions process of the present invention or only has the infringement can ignoring degree.
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.
