Planting / Soil Treatment
Protect seed tubers from Rhizoctonia (black scurf), soil-borne fungi, and nematodes. Apply fungicides and nematicides as furrow treatments at planting.
Pre-Emergence
Apply pre-emergent herbicides to control grass and broadleaf weeds before crop emergence. Critical window for clean establishment.
Post-Emergence / Early Growth
Control cutworms immediately after emergence. Begin scouting for aphids and apply post-emergent herbicides for escaped grass weeds.
Vegetative Growth
Begin routine fungicide program for early blight prevention. Manage aphids, thrips, and leaf miners that build up during canopy development.
Tuber Initiation & Bulking
Critical stage for late blight (Phytophthora infestans) prevention. Protect tubers from tuber moth and maintain disease-free canopy for maximum tuber bulking.
Maturation & Harvest
Final disease and pest management before harvest. Focus on tuber moth, late blight protection, and maintaining tuber quality. Observe pre-harvest intervals.
Safety Information
Always read and follow label directions. Wear appropriate personal protective equipment (PPE) when handling agrochemicals. Store in original containers in a secure location away from children and animals. Dispose of containers properly according to local regulations. Consult your local extension officer for region-specific recommendations.
