Product Overview
STEWARD® 150 EC has a novel mode of action. The product acts by inhibiting sodium ion entry into nerve cells, resulting in paralysis and death of the pest species. Death of the pest occurs within 1 - 2 days, but inhibition of insect feeding occurs very rapidly (within 2 - 8 hours).
STEWARD® 150 EC is active as a larvicide through ingestion (stomach action) and through cuticular absorption (contact action). STEWARD® 150 EC is equally active on larvae of all development stages except in the case of fall armyworm (Spodoptera frugiperda) where application is not recommended for the control of worms larger than 1 cm.
STEWARD® 150 EC is safe to most beneficial insects, including predatory mites.
STEWARD® 150 EC is also effective in hot climatic conditions.
