What is BIOESR R.S.N?
BIOESR R.S.N is a next-generation live bio-culture formulated with Azotobacter chroococcum – a beneficial soil bacterium that naturally suppresses harmful nematodes. It acts on the eggs, larvae, and pupae stages, preventing them from damaging plant roots.
Why Farmers Need It
Across our recent ESR Agro survey with 2,300 farmers, most reported serious yield loss caused by nematodes hidden in the soil. These invisible pests lay eggs inside root tissues, making plants appear weak, yellow, and nutrient-deficient. BIOESR R.S.N solves this problem from the root level – literally.
