Protect nursery seedbeds from damping off (Pythium, Phytophthora) and early pest pressure from whitefly, aphids, and caterpillars that transmit TMV and leaf curl virus.
Protect transplanted seedlings from cutworm damage and soil-dwelling pests. Apply insecticides immediately after transplanting to establish early protection.
Protect against early blight (Alternaria solani), powdery mildew, and insect pests during rapid vegetative growth. Begin preventative fungicide program before disease onset.
Critical stage for late blight (Phytophthora infestans) prevention. Protect flowers from thrips and maintain disease-free canopy to ensure fruit set.
Continue late blight and bacterial disease management during fruit development. Monitor for bollworm damage to developing fruit.
Final pest and disease management before harvest. Focus on red spider mite, whitefly, and maintaining fruit quality. Observe pre-harvest intervals for all products.
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.
