A Pilot Study of Natural Formulation Activity in the Protection of Stored Wheat and Barley Against the Stored-Product Insects

The stored-product insects are one of the major causes losses in stored cereals. Most control measures still rely on a synthetic pesticide usage, but due to its negative side effects goods, human health, and environment, there is an urgent need for alternative control. A natural formulation based diatomaceous earth (DE) SilicoSec®, enhanced with botanicals (essential oil lavender, corn oil, bay leaves dust) silica gel was developed. aim study test activity developed as postharvest protectant seed wheat barley suppression Sitophilus oryzae (L.), Rhyzopertha dominica (F.) Tribolium castaneum (Herbst). As reference comparative value, DE SilicoSec® applied. Subsequent six months storage under simulated warehouse conditions, has completely suppressed initial population development all three tested insect species, both barley. In wheat, complete detected at dose 500 ppm against T. 600 R. S. oryzae. barley, doses ppm, 400 dominica, oryzae, respectively. Conclusively, results this indicate that DE, botanicals, highly effective stored‐product providing long-term safe seeds.
