Silicato de potasio para controlar Oebalus insularis Stål en arroz en Quevedo, Ecuador

Oebalus insularis Stål, colloquially known as the rice stink bug, causes damage to rice crops, theproduction losses of which can range between 30 and 65%, which is why agroecological alternativesfor its control without the application of polluting synthetic chemicals are increasing. The researchaimed to assess the use of beneficial microorganisms and compost with silicon for the controlof O. insularis Stål, in Oryza sativa L., cultivar INIAP-14. The research was conducted in thesummer-autumn 2023 in Quevedo, Ecuador, under field conditions in a clay loam soil, using sixtreatments consisting of a control without any application (T1), Buffago insecticide at 0.5 L ha-1(T2); Azotobacter chroococcum, strain Ag, at 1 x 109 CFU ml-1 (T3); liquid compost with potassiumsilicate (K4SiO4) at 5 L ha-1 (T4); Metarhizium anisopliae, strain 45, at 1.2 L ha-1 (T5), and a combinedtreatment with A. chroococcum, liquid compost with potassium silicate, and M. anisopliae (T6), in acompletely randomized design. The dependent variable evaluated was the number of insects perplot before and after applying the treatments. The results show a significant variation in the insectpopulation before and after applying the treatments, with differentiated results between treatments,indicating that the use of combined treatments and that with Metarhizium show effective results tobe considered as an agroecological alternative in the control of Oebalus insularis bug
