Inventor has been carried out largely by substantial amounts of screening test to the different ratio of penoxsuam and benzobicylon
Experiment and preventive effect analysis, it is found that in certain ratio range, resulting herbicide has synergistic effect, and not only
It is the simple addition of two kinds of medicaments, is illustrated with following biologicall test example.
Pre-emergence test：
Under greenhouse experiment, test plant is seeded in seedling alms bowl.Cultivation matrix is used as using standard soil.The rank before bud
Section, herbicide individually or is in combination administered to soil surface.It is true that dosage depends on the institute under field or greenhouse experiment
Fixed optium concentration.The evaluation test after 2 ~ 4 weeks（100% effect=plant is completely dead；0% effect=plant-less toxicity effect）.
The combination of penoxsuam and benzobicylon is shown than more preferable preventive effect is administered alone in this test, and display is substantially
Synergistic effect.
When the herbicide of the present invention is applied before rudiment, weeds emergence or weed growth can be entirely prevented right to cotyledon period
After stop growing and completely dead after 3 ~ 4 weeks.
After seedling is tested：
Experiment：For different types of weeds（Barnyard grass, moleplant seed, flat stalk Fischer grass, Monochoria vaginalis, arrowhead, Procumbent Falsepimpernel, firefly Lin,
Bog pondweed, convexutricle sedge herb）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, Monochoria vaginalis, Herba Cyperi Glomerati,
Procumbent Falsepimpernel, firefly Lin, Herba Cyperi Glomerati, needle spikesedge herb.Add water untill the depth away from soil surface 3cm.One is planted under irrigation conditions
The section predetermined time.When plant reached for 3 ~ 4 leaf stage, by the seedling alms bowl for the predetermined number for growing plant be transferred to one it is square
Plastic tub in, be filled to thereto height be 3cm.Using back type sprayer by herbicide individually or as a mixture
It is administered in the test plants under water saturation edaphic condition.Dosage depends on identified optimal dense under field condition
Degree.Evaluation test after being chemically treated 3 ~ 5 weeks（100% effect=plant is completely dead；0% effect=plant-less toxicity effect）.Herein
The mixture used in experiment shows good result.
Three kinds of reagents are prepared according to constant weight percentage：1st, penoxsuam；2nd, benzobicylon；3rd, penoxsuam
+ benzobicylon.Above-mentioned each reagent is diluted with water afterwards, obtains medicament dilution.By the processing of medicament dilution it is certain when
Between after, observe respectively and barnyard grass, moleplant seed, flat stalk Fischer grass, Monochoria vaginalis, arrowhead, Procumbent Falsepimpernel, firefly Lin, bog pondweed, convexutricle sedge herb removed
Careless effect.
Herbicidal effect of the observation to barnyard grass after processing four weeks
To the herbicidal effect of firefly Lin after processing four weeks
To the herbicidal effect of arrowhead after processing four weeks
To the herbicidal effect of bog pondweed after processing four weeks
