See UF/IFAS results concerning research on using IPCs and brassinosteroids in Florida citrus for prolonged tree health.
“UF/IFAS research in the last three years has found that the combined use of individual protective covers (IPCs) and brassinosteroids (BRs) enhances protection of citrus trees against HLB and other diseases that limit citrus production in Florida,” shared a UF/IFAS Tip of the Week article. It shared the results of research by UF/IFAS into using IPCs and brassinosteroids. See the details below.
Research Into Using IPCs and Brassinosteroids
The article shared that “the research has been conducted on different varieties, including Tango and Early Pride mandarins as well as Hamlin and Valencia oranges grafted on sour orange or US-942 rootstocks. Trees were covered immediately after planting with IPCs. The covers remained on the trees for three years before removal. All trees tested negative for HLB.”
It added that “then, monthly foliar spray applications of BRs were made at a rate of 6.2 fluid ounces of product in 100 gallons of water.”
They shared results that the “treatment resulted in trees remaining HLB-negative for about six months without the IPCs. An increase in tree height and canopy volume resulted in an increase in biomass. Yield increased by 30% on average in BR-treated trees. This was consistent across variety and rootstock combinations.”
