Sulfuryl fluoride safe dosage test to mortality of Tribolium castaneum Herbst on corn and rice flour commodities in warehouse

Abstract

Abstract This study aims to examine the level of pest mortality of Tribolium castaneum on corn flour and rice commodities using SF exposure with different concentrations. This study used a factorial Completely Randomized Design (CRD) method. The materials used in this study were SF, fumigation equipments, corn flour and rice commodities. Observation variables include identification, mortality calculations, temperature and humidity calculations. Treatment types of SF doses were (1) 0 g/m3, (2) 10 g/m3, (3) 15 g/m3, (4) 21 g/m3, and (5) 30 g/m3 with each treatment combination was repeated two times. The data obtained were analyzed descriptively and statistically using the ANOVA and follow-up tests using the Least Significant Difference (LSD) test at the 5% level. Research innovation using a variety of food safe doses of SF to make the highest mortality from T. castaneum. The results show that there is a significant difference, the highest mortality was in the SF doses of 21 g/m3 and 30 g/m3 on corn and rice flour commodities. The effective dose of sulfuryl fluoride is 21 g/m3 with the highest death rate. This research can be used as a recommendation for pest control using effective and efficient doses of SF in controlling T. castaneum.
