Effect of Glucan Duo on Durian Flowering and Fruit Setting
Abstract: This field-based study evaluates the effect of Glucan Duo, a ?-glucan biostimulant, on the flowering and fruit setting performance of durian (Durio zibethinus L.). The experiment used a randomized block design with treatments including Glucan Duo at two concentrations, with and without reduced fungicide, alongside a full-fungicide control. Results revealed that Glucan Duo at 2 ml/L significantly enhanced flower cluster formation, improved flowering uniformity, and achieved the highest fruit set rate of 84?86%. While differences in fruit size and pedicle length were statistically insignificant, trends suggested better fruit development under Glucan Duo treatments. These outcomes support the role of biostimulants in reducing fungicide dependency and promoting sustainable durian cultivation.
