By Davie Kadyampakeni, Kondwani Kamsikiri and Alisheikh Atta Water scarcity is one of the major constraints in Florida citrus production systems, primarily due to erratic rainfall patterns and the low water- and nutrient-holding capacity of the predominantly sandy soils. The state’s soils contain more than 95% sand and have low organic matter (<1%) and very low water-holding capacity. These challenges …

Growers use the citrus under protective screen (CUPS) production system to protect trees from the Asian citrus psyllid, the insect vector of HLB disease. While grapefruit is most commonly grown in CUPS, statistics support the belief that CUPS can be conducive to other types of citrus. “There’s a need to establish the growing requirements and the needs of other varieties. …
By Ramdas Kanissery Managing weeds in citrus groves isn’t just about what you spray; it’s about when you spray.
