Close object suspending agent.Biological activity determination embodiment
4 active component A of embodiment compounds the indoor virulence effect measurement to weeds with active component B
By indoor pot experiment, synergy of the composition to weeds is specified.
The cultural method of weeds culture and test material are as follows: quantitative weed seed piemarker and Siberian cocklebur are sowed at diameter respectively is
In the dixie cup equipped with Nutrition Soil of 7cm, broadcast after rear earthing, suppression, water drenching in hot-house culture.Gramineae weed is long to 1.5~2 leaves
Phase, 2~4 leaf phase of broadleaf weeds, cauline leaf spraying treatment, test set 3 repetitions.Processing is put in greenhouse to medical fluid natural air drying
It manages according to a conventional method, according to the suppressed or dead situation of weeds, 30 days after processing, carries out range estimation preventive effect investigation.
Composition proposed by the present invention uses Gowing method to the evaluation of the synergy of weeds, calculates each mixture combination
Theoretical preventive effect E0Value and actual value E and theoretical value E0Difference (E-E0).Work as E-E0It is synergistic effect when > 10；E-E0< -10
For antagonism；E-E0Value is addition between ± 10.
Wherein X be component A when being applied alone with dosage P to the actual measurement percentage preventive effect of weeds, Y is when B component is applied alone with dosage Q pair
The actual measurement percentage preventive effect of weeds, E0To the theoretical percentage preventive effect of weeds when being used with for composition A+B with P+Q dosage.
The synergy to weeds mixed with active component B of 1 active component A 1 of table
The synergy to weeds mixed with active component B of 2 active component A 2 of table
Test result shows that active component A 1 and A2 are mixed with active component B nicosulfuron respectively, to broadleaf weeds piemarker
Apparent addition or synergistic effect are shown with gramineae weed barnyard grass.
After embodiment 5 determines application herbicidal composition of the present invention, the death rate of weeds, and with single group
Herbicide speed when point using is compared, and using the method for indoor pot, (culture of test material and processing method are the same as real for test
Example 4), piemarker and barnyard grass were 6 leaf phases when processing.
Table 3 applies herbicidal composition to the preventive effect (range estimation %) of weeds
Table 4 applies herbicidal composition to the preventive effect (range estimation %) of weeds
Test result shows that herbicidal composition accelerates herbicide speed.
