Symptoms of Panicle blast

 

 

1. At the time of flowering, areas near the panicle base are often attacked causing ‘rotten neck’ or ‘neck rot’ symptoms. 

2. Blackening at the principal nodes below the flowering axis is known as neck infection. 

3. The neck becomes shrivelled and covered with grey mycelium. 

4. The panicle with neck infection often breaks and falls off resulting in total loss of grains
