Nothing says summer like a ripe, juicy slice of watermelon on a hot day. However, this important summertime fare is under assault and may not even make it to the table; a tiny pathogen is ravaging crops, causing the rind to weaken and allowing the fruit to ooze out into the field.
The disease, called watermelon fruit blotch, accounts for losses of up to 90 percent of marketable yield in some watermelon fields. Fruit blotch was first detected in Florida in 1989. Since that time, it has migrated along the eastern seaboard and into Indiana, affecting 11 states. The rapid migration and expansion of this disease may lie in its seeds.
