PURPOSE:To provide the title agent having markedly synergistic effects, containing 4-chloro-N-(2-chloro-4-nitrophenyl)-alpha,alpha,alpha-trifluoro-m-tolu enesulfonamide and O-2,6-dichloro-p-tolyl=O,O-dimethyl=phosphorothioate. CONSTITUTION:The objective agent containing (A) a compound of formula I and (B) a second compound of formula II at the weight ratio A/B=(1:1)-(1: 60) with both the components as active ingredient accounting for 0.2-80wt.% of the final agent. Examples of the disease injuries effective for the present agent are as follows: root knot in the vegetables classified as Cruciferae, common scab, scurf in potato, root rot, etc., in Beta vulgaris, and damping-off, root rot and southern blight in vegetables. The synergistic effects due to mixing these two components will not only result in advantages in efficiency and economy, but also enable the reduction in the application amount of each component, thus being favorable in safety in terms of environmental pollution control. The amount of application of each component is, on an active ingredient basis, 400-5000g per 10a. |
