Conidial viability, biopesticide formulations, antagonistic fungi, biological inputsAbstract
The use of antagonistic fungi as an alternative to agrochemicals for pest control is a key strategy for sustainable agriculture. In this study, the viability and conidial concentration of Trichoderma sp. strain FRAIII were evaluated in wettable powder formulations using different inert materials. Diatomaceous earth, wheat flour, and calcium silicate were used, with rice serving as the control. Viability and conidial concentration were highest in the formulations with diatomaceous earth, followed by wheat flour and calcium silicate. In contrast, viability in the rice-based formulation decreased by 20.87% between each evaluation. The results suggest that diatomaceous earth is a suitable carrier material for maintaining the stability of Trichoderma sp., potentially enhancing the effectiveness of biopesticides in agricultural systems.
