Jul 30, 2024Almond orchards grapple with high heat, pests
Almond growers in California faced a challenging July, marked by a relentless heat wave and ongoing pest issues, according to Blue Diamond’s latest crop progress report. From July 1-28, temperatures soared above 100º F for up to 14 consecutive days in some areas, significantly complicating orchard management.
“These extreme temperatures have made it tough for growers to manage irrigation and prevent tree stress,” said Mel Machado, director of member relations at Blue Diamond in the crop report.
Despite the heat, preparations for the upcoming harvest continued. Growers implemented Regulated Deficit Irrigation to combat fungal infections, a method that reduces water usage temporarily to alter the micro-climate within splitting hulls. However, excessive temperatures increased water consumption, making proper irrigation more challenging.
Pest management remained a priority, with growers conducting multiple treatments for NOW and monitoring the reappearance of the Carpophilus beetle, a pest first reported in the 2023 crop. Additionally, ant bait applications were completed ahead of shaking in susceptible orchards.
Harvesting of the earliest Nonpareil plantings began in the final days of July, with more expected to start in early August. Orchard removals continued, raising questions about future land use.
