Preharvest factors like where citrus fruits are grown, how they are cared for, and when they are harvested can greatly affect their quality and how many are lost after harvest. By managing things like rootstock, pruning, and pest control before picking, postharvest losses can be reduced. Some methods, like using certain growth regulators, still need more research to see how they can help. Overall, taking good care of citrus fruits before they are picked can lead to less waste and better quality in the end.
