摘要：

Anthracnose disease is a significant limiting factor for Florida leatherleaf fern (Rumohra adiantiformis) production. Symptoms of anthracnose are produced by the fungal pathogen Colletotrichum acutatum Corda. The damage to the fern fronds can be extensive and unsightly rendering the fronds unsalable. Colletotrichum acutatum is also the casual agent of postbloom fruit drop (PFD) in citrus and strawberry anthracnose on strawberry. Keyplex (R) products have been shown to significantly reduce PFD in citrus (EPA bio-pesticide label 73512-1). A trial was conducted in 2011 to determine if Keyplex (R) could reduce anthracnose in leatherleaf fern and to determine what rate would be most appropriate. Treatments at 0.5, 1, and 2 pints (0.237 L, 0.476 L, and 0.946 L) per acre resulted in significantly less disease incidence. In 2013 a follow up trial was conducted which reaffirmed there were significant differences in number and severity of infected fronds between treated and untreated areas.
