Making Headway Toward Machine Harvesting of Blueberries
By Doug Phillips With rising costs and declining availability of harvesting labor, blueberry growers are increasingly interested in considering machine harvesting for their crops. Cost is a particularly important factor because of declining profit margins due to competition from lower-cost areas of production. PROS AND CONS Hand harvesting produces high-quality fruit, but can cost between $0.70/pound and $0.90/pound for local …
Mechanical Strawberry Harvester Could Solve Labor Shortage
Labor continues to be a pressing issue for southeastern agriculture. However, in Florida, new technology on the horizon may offer a glimmer of hope. Gary Wishnatzki, owner of Wish Farms and co-founder of Harvest CROO Robotics, is working to create a mechanical harvester that could revolutionize the strawberry industry.

Spider Mite Research Heats Up
Two-spotted spider mites are a major issue in Florida strawberries. Justin Renkema, former assistant professor at the University of Florida (UF), says mites make their way into Florida fields by blowing in from neighboring fields, but they may also be coming on strawberry transplants from nurseries. After proving that spider mites were coming to Florida on transplants, Renkema wanted to …
Managing Spider Mites in Florida Strawberries
As two-spotted spider mites continue to be a serious issue in Florida strawberry fields, Justin Renkema, former assistant professor at the University of Florida, has been working with his colleagues to figure out where these spider mites come from and how best to manage them. He has conducted spider mite research over the past two strawberry seasons. Renkema presented his …
Citrus Root Weevil Invades Florida Blueberries
The Florida Blueberry Growers Association (FBGA) and the University of Florida (UF) are warning Florida blueberry growers to be on the lookout for citrus root weevil. A pest that has been an issue in citrus for years has made its way on to another crop entirely, causing significant damage in central and south central Florida.
