Biological formulation process containing the Bacillus subtilis strain used in agriculture for pest control: case of the cactus mealybug Dactylopius opuntiae

Abstract

The invention relates to an environmentally friendly and innovative process, "a formulation based on the bacterial strain Bacillus subtilis PQ517008," for the control and treatment of Dactylopius opuntia (cactus mealybug) infestations on Opuntia ficus-indica. The invention also relates to a method for producing and applying said strain under optimal conditions for improved control of the cactus disease. The strain has been filed with the National Center for Biotechnology Information under the registration number PQ517008 by our research team. The proposed treatment is harmless to both the health of the cacti and the environment, and significantly reduces mealybug populations while improving the growth and resistance of the host plants. The invention offers a safer and more sustainable alternative to conventional chemical treatments, providing improved plant resistance and integrated pest management (IPM) for sustainable agriculture.
