Canopy Management Needed for Cold-Hardy Citrus
Pruning may help cold-hardy producers salvage their satsuma crop from one year to the next and not endure extreme alternate bearing cycles. “Pruning in the heavy year may help alleviate that alternate bearing pattern. But we still have to do the research to support that,” said Mary Sutton, University of Georgia (UGA) assistant professor and citrus Extension specialist. While pruning …
Emerging Varieties Program Offers Opportunities for Growers
There has been high interest in the Citrus Research and Field Trial (CRAFT) Foundation programs recently as a new cycle of applications has been bolstered by record funding of more than $100 million from the Florida Legislature. This includes the introduction of a new CRAFT program called the Emerging Varieties Program. It will provide citrus growers with a $40 per …
Phytophthora Root Rot a Concern in the Cold-Hardy Region
Phytophthora root rot’s impact on young citrus trees is concerning for groves in the cold-hardy citrus region of North Florida, South Georgia and South Alabama. Newly planted trees are more vulnerable to the disease than older, established trees, says Jonathan Oliver, University of Georgia assistant professor and small fruits pathologist. He discussed the disease’s impact during the Citrus Grower’s Summer …
