Several different fungi and one bacterium cause leaf spot diseases of Florida strawberry. Symptoms caused by these pathogens are often similar, leading to confusion and misdiagnosis of the disease. To facilitate diagnosis, the most common leaf spots diseases of strawberry in Florida are described in this new 6-page article, written by Juliana S. Baggio, James C. Mertely, and Natalia A. Peres, and published by the UF/IFAS Plant Pathology Department.
Pestalotiopsis-like fungi cause diseases on many different species of plants worldwide, including strawberry. The pathogen is not necessarily new to strawberry and was first reported causing fruit rot in Florida and Israel in the 1970s. However, during the 2018–19 and 2019–20 strawberry seasons, severe and unprecedented outbreaks were reported in Florida, characterized by symptoms on nearly all plant parts including roots, crowns, petioles, fruit, and leaves. This new 4-page publication of the UF/IFAS Plant Pathology Department describes the disease and its causal agent and briefly covers what is known about disease development and control practices. This document will provide valuable information to strawberry nursery and fruit production growers. Written by Juliana S. Baggio and Natalia A. Peres.
Fusarium wilt of lettuce is a disease caused by the fungus Fusarium oxysporum f.sp. lactucae. The disease is present in all lettuce production areas worldwide. Recently this disease has been identified in Florida in localized fields. This new 4-page publication of the UF/IFAS Horticultural Sciences Department presents information about the disease, symptoms, and control measures useful to lettuce growers in Florida. Following these recommendations may help to avoid the spread of this fungus in muck soils at the Everglades Agricultural Area (EAA), where 90% of the lettuce in Florida is planted.
