PURPOSE:To obtain the title composition controlling important weeds in paddy fields by one treatment, containing a 4-ethyl-3-substituted phenyl-(3-trifluoromethyl phenyl)-2-pyrrolidinone derivative and alpha-(beta-naphthoxy)propionanilide as active ingredients. CONSTITUTION:The title composition containing a compound (new substance) shown by the formula (R is H, F or Cl; X is H, F, CF3, CH3, CN, NO2, etc.; n is 1 or 2) and alpha-(beta-naphthoxy)propionanilide in the weight ratio of 1:2-100. Both the components show synergistic actions which can be expected by separative use of each component and the composition can be used any period from prior to emergence of weeds before rice transplanting to a growth period. The composition is preferably used by flooding soil treatment and an application amount is properly 0.5-5kg/ha. |
