Sigatoka leaf spot is managed by a combination of field sanitation and timely fungicide sprays. First, remove and destroy badly infected and hanging lower leaves, improve drainage, and avoid waterlogging since high humidity drives the disease. Maintain correct spacing for air movement and avoid excess nitrogen. For chemical control, alternate protectant and systemic fungicides as per the recommended package, and add a sticker or mineral oil for better leaf coverage. Rotate fungicide groups to prevent resistance. Always follow the label dose and the latest advisory from your state agricultural university, as approved molecules and doses change over time.

In our Theni area the black sigatoka gets bad in the rainy months. Removing the lower diseased leaves every week and not crowding the plants helped me a lot before I even needed to spray.

One mistake I made early was spraying the same systemic fungicide again and again. It stopped working within a season. Now I rotate groups strictly as the KVK lists and the disease stays in check. Resistance is real, do not skip the rotation.

If you are sending fruit for export, watch the pre-harvest interval on every fungicide carefully. Buyers reject consignments on residue limits, so keep a spray diary with dates and products and follow the label PHI without shortcuts. Our exporter checks this record before lifting the fruit.

Coverage matters as much as the chemical. The disease starts on the underside of leaves, so I make sure the spray reaches there and add the recommended sticker. A high-volume spray that drips off does less than a well-set fine spray that actually coats the leaf.
