Blister blight is the major leaf disease of tea in the Nilgiris, attacking young plucked shoots during the wet misty monsoon and forming translucent blisters that burst into white powdery spore patches, reducing made tea yield and quality. Control it with protective fungicide sprays such as copper oxychloride before and during the wet season, and systemic fungicides like hexaconazole or propiconazole during high incidence, rotating to avoid resistance and following label and residue rules. Time sprays to the plucking round since new flush is most vulnerable. Reducing excess shade improves air movement and light, which lowers disease. Pruning during the dry months helps reduce carryover inoculum. Follow the tea research foundation schedule for your area.

In the wet months here the blister blight comes fast on the tender shoots. Copper sprays as a protectant before the monsoon, then systemic when it is bad, kept my fields cleaner. Tie sprays to the plucking round.

Too much shade and still air makes it worse. Opening up the shade trees a bit improved air flow and light and the disease pressure dropped on my section. Pruning in the dry spell helps too.
