If the active ingredient is unprotected on the soil surface, a large portion may be lost from ultraviolet degradation. Plant injury symptoms. Dinitroanalines affect root development. Effects include swollen root tips and stunted lateral and secondary roots. Dinitroanilines primarily kill germinating seedlings, not established plants.
Major losses can occur from volatilization.
To maintain effectiveness, incorporate thiocarbamates immediately. This usually means tillage, unless adequate rain falls. Because different Crops usually require different herbicides, lack of crop rotation can lead to accelerated degradation and a resulting loss of herbicide effectiveness. Plant injury symptoms. Thiocarbamates affect shoot development.
