The goal of this research was to identify the role essential nutrients play in the physiology of tree crops, and then to apply the nutrient as a foliar fertilizer to stimulate a specific metabolic process at phenological stages when nutrient demand is high. This approach has proven successful. A single winter prebloom foliar application of nitrogen as low-biuret urea [0.16 kg N/tree (0.35 lb N/tree)] to 30-year-old ‘Washington’ navel orange (Citrus sinensis L. Osbeck) trees during flower initiation significantly increased yield and fruit number per tree for each of 3 consecutive years (P ≤ 0.05).
Citrus huanglongbing (HLB), or greening, is the most destructive citrus disease worldwide and is threatening the sustainability of the industry in major citrus-growing regions. Various treatments have been proposed in the literature to manage the disease. We review such literature and conduct an economic analysis based on the reported treatment effects on fruit yield and quality to identify cost-effective management strategies.

Ten months ago, in March 2020, we predicted a bumper export season, estimating that export volumes would reach 143 million cartons of fruit. Now that the final export figures are in, we can announce a record-breaking 2020 export season that delivered 146 million cartons of South African citrus to the rest of the world,” said Just Chadwick CEO of the Citrus Grower’s Association in South Africa.
