When to act
Walk the field from flowering and look for plants that wilt and dry in patches, with a purple band up the stem and brown streaks inside. Pull and burn them. There is no spray threshold.
What to spray
- CarbendazimFRAC 1ShopeeLazada
- Trichoderma virideBIOShopeeLazada
- Trichoderma harzianumBIOShopeeLazada
Active ingredients only, never brands. The FRAC group tells how it works: switch to a different group next time, so the disease does not learn to survive it. Spray only when the damage is worth the cost, and only with products registered with the Fertilizer and Pesticide Authority for your crop. Follow the label. The Shopee and Lazada links only show who sells something with that active ingredient, not a recommendation of any seller or product.
No spray saves a wilting plant. Plant resistant varieties, treat seed with Trichoderma and rotate with grains.
How to prevent it
- Plant a wilt resistant variety. It is the main answer to this disease.
- Rotate for three years with sorghum, corn or other grains, or intercrop pigeon pea with sorghum.
- Use clean seed from healthy fields, treated with Trichoderma before sowing.
- Pull and burn wilted plants with their roots, and do not leave infected stubble in the field.
- Drain the field well. Waterlogged soil makes the wilt worse.
Natural enemies and biological help
- Coat the seed with Trichoderma viride or Trichoderma harzianum before sowing, and add it to compost for the rows.
