Buy Beauveria Bassiana for Banana – Control Pseudostem Weevil and Root Weevil

Your banana plants – Nendran, Robusta, or Poovan – are valuable. But pseudostem weevil is a silent killer. Grubs bore into the pseudostem, creating tunnels. Colourless jelly‑like sap oozes from boreholes, leaves turn yellow, and eventually the plant collapses. Root weevil larvae feed on the corm and roots, causing slow decline and toppling. Chemical controls are often ineffective because the larvae are inside the plant or deep in the soil.

Beauveria bassiana is your organic answer.

What the research says: The Kerala Agricultural University (KAU) recommends spraying Beauveria bassiana at 20g per litre of water or 5 ml per litre, covering the leaf axil and pseudostem at 5 months after planting. Research trials have shown that Beauveria bassiana (1×10⁷ spores/ml) spray at 5th, 6th, and 7th months after planting, combined with stem trapping, gives better results against banana stem weevil. The ICAR‑National Research Centre for Banana (NRCB) has developed a rice chaff grain formulation of Beauveria bassiana, which is equally effective and can be produced by self‑help groups.

How to apply Beauveria on banana:

Pre‑planting pit treatment (for root weevil prevention):

  • Take 200‑250g of Bactostore's Beauveria powder per pit

  • Mix with 10‑15 kg of well‑decomposed FYM

  • Incorporate into the pit soil before planting the sucker

Sucker treatment (before planting):

  • Mix 10g of Beauveria powder (or 10 ml liquid) in 1 litre of water

  • Dip the banana sucker or tissue‑culture plantlet for 10‑15 minutes

  • Shade dry for 30 minutes before planting

For pseudostem weevil (KAU method):

  • Mix 20g of Beauveria powder in 1 litre of water (or use 5 ml liquid per litre)

  • Spray the solution on the leaf axil and pseudostem

  • Apply at 5 months after planting (135 days after planting)

  • Also spray the cut surface of split pseudostem traps placed in the garden

  • Repeat at 6th and 7th months after planting for best results

Soil drench for root weevils (every 2‑3 months):

  • Mix 200‑250g of powder (or 200‑250 ml liquid) in 10 litres of water

  • Drench around the root zone
