The florpyrauxifen of table 3 and the different monooctyl ester different ratio preventing and treating rice weed of the fluroxypyr test of pesticide effectiveness
From above-mentioned data, it is apparent that complex preparation exceedes to barnyard grass, clearvers 15 days, the preventive effect of 30 days
90%, after two kinds of compositions compound, there are good preventive effect, for single dose, synergy to grassy weed and broad leaved weed
Effect is obvious.Visually, used in this experiment in dosage range, to rice safety.
As can be seen here, after two kinds of composition compoundings of florpyrauxifen and the different monooctyl ester of fluroxypyr, to weeds in field
Herbicidal effect far above the herbicidal effect of two kinds of single doses, synergistic effect is notable after compounding, lasting period length, is expanding herbicidal spectrum
Meanwhile the spraying times for reducing peasant are increased economic efficiency so as to reduce the amount of labour of peasant.
