Application of protect-ITtm in process of integrated pest management of stored grains

Abstract

Alternative way to chemical control of stored-product insects is use of diatomaceous earth (DE), which is effective as insecticidal dust. Preparation Protect-ItTM was used in this experiment for investigation of DE efficacy, worldwide registered for protection of stored products against pests. Detrimental species Rhizopertha dominica was examined on all small grain species - wheat, barley, rye, oat and triticale. Applied pesticide rare of I,0 g/kg was caused statistically significant higher percentage of mortality compared with rate of 0,5 g/kg. Mortality percentage of R.dominica is higher after longer exposure. In relation to type of grain exist statistically significant difference in adult mortality. Within rye and triticale statistically significant lower percentage of mortality was achieved.
