Citrus growers need every available tool to fight disease, reduce tree stress and keep groves healthy against Phytophthora root rot.
According to the University of Florida Institute for Food and Agricultural Sciences (IFAS), Phytophthora root rot is one of the most important diseases threatening citrus yield. This disease can be caused by different species within the genus Phytophthora, a water mold in the Oomycete class, and can be found around the world. The pathogen produces motile zoospores, which can enter plants through root tips and cause rot. The symptoms commonly seen above ground include yellowing of foliage, abscission of leaves, dying shoots and reduced fruit size and yield.
Phytophthora root rot damage begins below the soil, then extends through root systems and ultimately affects entire trees. Declines in overall tree health happen rapidly, sometimes within a year under wet conditions. A strong and healthy fibrous root system is essential to overall tree health and productivity, so active management of Phytophthora root rot is essential.
Orondis® fungicide is a unique, powerful option to protect against Phytophthora root rot in citrus. The active ingredient, oxathiapiprolin, is in FRAC Group 49 and is a unique mode of action. Orondis protects developing citrus root systems and improves root health by significantly reducing the number of viable Phytophthora propagules and inoculum potential in the soil. Orondis protection can improve root mass, facilitate better water and nutrient use, improve root health and ultimately increase yield and profit potential for citrus growers.
