In order to preferably embody the weed control efficacy of herbicide of the present invention, said below with reference to specific experiment data
It is bright.
Biological test example
When the effect of herbicide exceedes the summation of the effect when each component is administered alone, there is synergistic function.
The predictive role of two kinds of particular combinations of component can be used so-called " Colby formula "（Referring to S.R. Colby, "
Calculating Synergistic and Antagonistic Responses of Herbicide Combinations
", Weeds 1967,15,20 ~ 22）It is calculated as below：If
X is to work as the component for using that consumption is mg/ha or concentration is mppm（a）When activity；
Y is to work as the component for using that consumption is ng/ha or concentration is nppm（b）When activity, be expressed as accounting for untreated right
According to percentage；
E is to work as the component for using that consumption is m and n g/ha or concentration is m and n ppm（a）With（b）When activity,
So
If the activity of actual observation（O）More than expection activity（E）, then said composition is super to be added and makees with synergy
With.
Inventor by substantial amounts of screening test, to component（a）And component（b）Different ratio carried out a large amount of experiment
And preventive effect analysis, finding in certain ratio range, resulting herbicide has a synergistic effect, and not exclusively two kinds
The simple addition of medicament, is illustrated with following biologicall test example.
Before seedling is tested：
Under greenhouse experiment, test plant is seeded in seedling alms bowl.Using standard soil as cultivation matrix.In before seedling rank
Section, soil surface individually or is as a mixture administered to by herbicide.Consumption depends on the institute under field or greenhouse experiment
The optium concentration of determination.In the experiment of post-evaluation in 2 ~ 4 weeks（100% effect=plant is completely dead；0% effect=plant-less toxicity is made
With）.The combination of benzobicylon and bentazone in this test is shown than more preferable preventive effect is administered alone, and display is obvious
Synergistic effect.
When herbicide of the invention before rudiment when applying, can entirely prevent that weeds emerge or weed growth is right to cotyledon period
After stop growing and by completely dead after 3 ~ 4 weeks.
After seedling is tested：
Experiment：For different types of weeds（Barnyard grass, fake rice, Monochoria vaginalis, angustifolia arrowhead herb, Procumbent Falsepimpernel, firefly Lin, bog pondweed, three
Rib grass）Carry out Herbicidal Testing Trials.
Test method：In seedling alms bowl（Diameter 8cm × depth 12cm）The middle paddy soils for loading depth about 8cm, add in the basin
Water is simultaneously subject to smooth, is stood three days, in the depth away from soil surface about 0.5cm, sowing barnyard grass, fake rice, Monochoria vaginalis, open country
Arrowhead, Procumbent Falsepimpernel, firefly Lin, bog pondweed, convexutricle sedge herb.Add water untill the depth away from soil surface 3cm.Sowed in irrigation conditions
Plant a predetermined time segment.When plant reached for 3 ~ 4 leaf stage, the seedling alms bowl that will grow the predetermined number of plant is transferred to one
In square plastic tub, height is filled to thereto for 3cm.Using back type sprayer by herbicide individually or with mixture
Form is administered in the test plants under water saturation edaphic condition.Consumption depends on identified optimal under field condition
Concentration.The chemical treatment experiment of post-evaluation in 3 ~ 5 weeks（100% effect=plant is completely dead；0% effect=plant-less toxicity is acted on）.
The mixture used in this experiment shows good result.
Three kinds of reagents are prepared according to constant weight percentage：1st, benzobicylon；2nd, bentazone；3rd, benzobicylon+go out
Careless pine.Afterwards by above-mentioned each reagent dilute with water, medicament dilution is obtained.After medicament dilution is processed into the regular hour, point
Do not observe to barnyard grass, fake rice, Monochoria vaginalis, angustifolia arrowhead herb, Procumbent Falsepimpernel, firefly Lin, bog pondweed, convexutricle sedge herb herbicidal effect.
The herbicidal effect to Monochoria vaginalis is observed after treatment four weeks
To the herbicidal effect of angustifolia arrowhead herb after treatment four weeks
To the herbicidal effect of barnyard grass after treatment four weeks
To the herbicidal effect of firefly Lin after treatment four weeks
To the herbicidal effect of convexutricle sedge herb after treatment four weeks
