Hi
Are you experiencing fruit drop in kinnow mandrins?? Imbalance of growth regulators and plant pathogens has been found to be responsible for causing this problem. The pathological fruit drop (Colletotrichum gloeosporioides) in the month of September and October is the most detrimental, as the fruits are near maturity and have drawn nourishment from the tree. As per one of the research Propiconazole + 2,4-D spray helped control fruit drop.
