Diseases
| Disease | Symptoms & Control Measures |
|---|---|
| Black Rot | First signs often appear along the leaf margins as chlorotic regions, with the chlorosis progressing toward the mid rib to form a V-shaped area; symptoms may appear from any side or the centre of the leaves. The bacteria are seed-transmitted. Control with disease-free seeds and resistant hybrids, and spray Copper Oxy Chloride 50% WP + K Cycline (2.5g + 0.5g/L). |
| Leaf Blight | Pin-sized black specks on the leaf surface or stem that enlarge concentrically into a distinct target-spot/bull's-eye lesion with a yellow halo. Control with Fluxapyroxad 250 G/L + Pyraclostrobin 250 G/L SC (0.3ml/L). |
| Downy Mildew | Small brownish spots on leaves; a whitish powdery mass appears on the lower surface during cloudy weather, causing defoliation. Spray Fenamidone 10% + Mancozeb 50% WG (2.5g/L) or Metiram 55% + Pyraclostrobin 5% WG (2g/L). |
Pests
| Name of the Pest | Symptoms & Management |
|---|---|
| DBM | Causes damage to leaves by making holes, leading to severe damage. Control with Chlorantraniliprole 18.5% SC (0.3ml/L), Spinosad 45% SC (0.15ml/L). |
| Loopers & Borers | Voracious eaters of leaves. Control with Chlorpyriphos 50% + Cypermethrin 5% w/w (2ml/L), Emamectin Benzoate 5% SG (1g/L). |
| Aphids | Suck sap from leaves causing leaf distortion. Control with Acephate 20% SP (1g/L). |
| White Fly | Suck sap from leaves causing leaf distortion. Control with Diafenthiuron 40.1% + Acetamiprid 3.9% WP @1.5g/L. |
