Managing Fungal Pressure in the Monsoon: A Practical Guide

Monsoon humidity above 85% combined with warm temperatures creates ideal conditions for fungal and bacterial outbreaks. Late blight, powdery mildew, and anthracnose spread fastest during prolonged leaf wetness. The key to control is prevention before the symptoms appear.

Window-based spraying

Rain washes away any foliar application, so time sprays to a 24–48 hour dry window. Spray in the early morning after dew dries, or late evening. Never spray in full sun or immediately before rain.

Rotation is non-negotiable

Alternate between protectant modes of action. Using the same product repeatedly allows pathogens to develop tolerance. Botanical extracts containing multiple active compounds naturally slow resistance build-up.

• •Monitor humidity and leaf-wetness daily during monsoon
• •Spray only in dry windows of 24–48 hours
• •Add a sticker/spreader so the spray dries before rain
• •Remove infected leaves and debris from the field
• •Rotate between botanical protectants all season

After heavy rainfall, replenish nitrogen that washes out and strengthen the crop with an immunity product. Stressed plants recover faster when given nutrition and protection together.
