anthracnose of cantaloupe

Anthracnose of cantaloupe-The lesions of anthracnose of cantaloupe on leaves appear generally round with zig-zag margins. However, the lesions do not usually appear as jagged as those of anthracnose of watermelon. I don’t observe as many cases of anthracnose of cantaloupe as I do on watermelon. This may simply be due to the larger acreage of watermelon in Indiana. However, it is important to remember that anthracnose of cantaloupe is usually caused by race 2 of Colletotrichum orbiculare, the same race that affects cucumber. Anthracnose on watermelon is caused by race 1.
