The redness of peach leaves is mainly related to the inheritance of varieties. The old leaves of common early-maturing peach varieties turn red in summer; After harvesting of individual late-maturing varieties, the water imbalance of leaves quickly aged, and the temperature was low at night in late autumn, which accelerated the decomposition of chlorophyll in leaves and made anthocyanins appear and turn red.

In addition, pink leaf disease can also make leaves red

Control aphids, planthoppers, leafhoppers, red spiders, scale insects, etc., which are easily transmitted by sucking mouthparts
