Fusarium wilt symptoms on pepper include margining yellowing of the affected pepper plants and entire plant wilting. The disease can affect scotch bonnet pepper and other peppers.

The disease symptoms can be easily confused with symptoms of bacterial wilt of pepper. However, plants affected by Fusarium wilt will not have bacterial steaming or ooze as in case of bacterial wilt.

Internal discoloration of the stem can be noticed in the crown region of the stem in case of Fusarium wilt, but may not be always seen. Culturing of plant samples will be necessary to confirm.

Fusarium sp. macrosconidia (spores) are hyaline, multi-septate, curved and pointed at both ends. The pathogen is soil-borne and can survive in soil for many years.
