CK: clear water control.
Control time and number: 3d, 7d, 15d, 30d after medicine observe leaf color, the growing way of each cell rice respectively, estimate water
The safety of rice mined grade and medicament to rice；Preventive effect uses chessboard method, and every cell takes at 5 points, area 0.25m2, after medicine
30 days investigation plant preventive effects.Test result table 2.
Medicament of the present invention field control effectiveness test result see the table below 2.
2 field control effectiveness test weeding result of table (after medicine 30 days)
As known from Table 2, after oxaziclomefone and penoxsuam compounding to barnyard grass, semen euphorbiae, Monochoria vaginalis medicine after 30 days
Preventive effect is reducing penoxsuam and oxaziclomefone combines dosage 80% or so, and after benthiocarb is added, to a thousand pieces of gold
Sub, barnyard grass preventive effect is remarkably reinforced, and has reached 90% or more, has not also weakened to the preventive effect of Monochoria vaginalis, omit instead
Micro- enhancing can speculate that the addition of benthiocarb not only enhances the preventive effect to barnyard grass semen euphorbiae, also enhance oxaziclomefone and
Penoxsuam is to the preventive effect (it is poor to Monochoria vaginalis preventive effect that benthiocarb is applied alone) of Monochoria vaginalis, it follows that the present composition
There is excellent preventive effect to paddy field weed, meanwhile, also reduce the dosage of medicament.In addition, the present composition is administered
Any unfavorable factor is not generated to the growth of rice during observation, does not also have phytotoxicity phenomenon, it is seen that the present composition
To Security of rice height.
In summary, it is recommended to use the ternary weeding composition of benthiocarb of the present invention, penoxsuam and oxaziclomefone,
Be conducive to increase drug effect mutually, have no antagonism, and expand degrass spectrum, solve the problems, such as that resistance barnyard grass is prevented and kill off, reduces by five fluorine sulphurs
Careless amine dosage delays its resistance to generate, can substantially reduce the use cost of peasant household, there is a drug to solve rice field a variety of miscellaneous
The effect of grass.
