Biostimax^® is a plant supplement that requires a foliar application. To make the solution, mix it with water to create a 0.3% to 0.5% suspension, which should then be sprayed on the green parts of the plants using any spraying method. You can even use a drone for this purpose. During the complete vegetation period, spray the solution every 15-30 days. You can treat plants more often if exposed to stressful conditions.
