* Diseased leaf samples exhibited distinct lesions and were analyzed in a lab, leading to the identification of a pathogen associated with the symptoms through microbiological techniques.
* Three specific isolates of the pathogen were characterized for their unique spore structures and genetic sequences, contributing to a better understanding of the disease affecting watermelon crops in the region.
Fusarium wilt of watermelon (Citrullus lanatus), caused by Fusarium oxysporum f. sp. niveum (Fon), has reemerged as a major production constraint in the southeastern USA, especially in Florida.
