Control rice blast by growing resistant varieties, avoiding excess nitrogen, and spraying a recommended fungicide like tricyclazole at first sign of spindle-shaped leaf lesions and again at booting to protect against neck blast. Neck blast at the panicle base is the most damaging stage and can cause whiteheads and big yield loss. Treat seed before sowing, maintain field hygiene, and avoid late evening irrigation that keeps leaves wet. Blast is worse in cool, humid hill weather and under heavy nitrogen, so split nitrogen doses. Use only the labelled fungicide dose and rotate chemistries to avoid resistance. Confirm choices with your local KVK.

In our hills neck blast hits if we put too much urea. I now split urea in 3 doses and spray at booting.

The booting stage spray is the one not to miss. Leaf blast scared me but it was the neck blast at heading that actually cut my grain. Protect the neck before panicles emerge.

Cool, foggy mornings in the hills are the danger sign. When dew sits long on leaves, blast spreads. I avoid evening irrigation so leaves are not wet all night.

Choosing a resistant variety from the hill agriculture office cut my spraying. No variety stays resistant forever though, so do not skip the other steps. Ask the KVK which one is holding up in your area now.

Caution on tricyclazole, follow the label dose and pre harvest interval strictly. Some export buyers reject grain with residue, so do not spray late near harvest.
