Three New Rootstocks Help Growers Manage Avocado Root Rot
from The Grower
Three new rootstocks may help avocado growers battle Phytophthora root rot, a multi-million-dollar problem in California. The roostocks—Zentmyer, Steddom and Uzi—are the product of University of California, Riverside, plant pathologist Greg Douhan, and his team, according to a news release. In addition to being Phythophthora tolerant, each rootstock has other desirable attributes. Zentmyer, for example, is extremely vigorous but is not salt tolerant. It also often doesn't yield consistently under non-root-rot conditions. Steddom has tolerance to both root rot and salinity.
