Aphid Infestation

Aphids are highly common on Rosa multiflora and secrete 'honeydew,' a sticky, sugar-rich substance as they feed on plant sap. This residue often leads to the growth of black sooty mold on the leaf surfaces.

Very Common

Whitefly Infestation

Whiteflies reside on the undersides of Rosa multiflora leaves and produce honeydew during their feeding process. A sudden cloud of tiny white insects may emerge when the foliage is disturbed.

Common
