Get Ahead of Phytophthora Root Rot

May 15, 2017

With several years of drought affecting the West, fruit and nut growers are now facing an underground issue. With Phytophthora root rot infecting the tissue of plants, issues like poor vegetative growth, long-term orchard decline, and possible tree death begin to increase.

Magnified by irrigation changes, the recent wet winter, and salty water, Phytophthora is making its way through the soil of California. The best way to detect for infection is by digging up roots and getting tissue tested for the presence of a specific Phytophthora protein. Not treating the disease can have a significant impact on yield.

Syngenta offers the Soil Pathogen Assessment (SPA), a free program that assesses Phytophthora infections on a field-by-field basis. Contact your Syngenta representative to learn more about soil sampling through the SPA program: www.Syngenta-US.com/rep-finder.

To combat this disease, water management is key. Make sure the soil is not too saturated, as this can allow the Phytophthora mold room to live and grow. In addition, consider applying a fungicide like Ridomil Gold® SL. By applying Ridomil Gold SL, growers can expect to see improved stand, root health and crop vigor to help maximize return on investment.
