How do I control leaf miner and aphids in exotic chrysanthemum without spoiling the flowers?

Leaf miner leaves winding trails in the leaves and heavy attack weakens the plant and spoils the look, while aphids cluster on tender shoots and buds, suck sap and leave sticky honeydew that brings sooty mould, both hurting cut flower quality. Manage them with monitoring using yellow sticky traps, removing and destroying badly mined leaves, keeping the crop clean of weeds that host these pests, and encouraging natural enemies. For sprays, use only products labelled for the crop and pest, follow the label dose and the waiting period before harvest so there is no residue on flowers you are selling, and rotate modes of action to avoid resistance, which leaf miner develops quickly. Avoid blanket spraying near flowering. Get a current control programme for these pests from your KVK or a floriculture specialist suited to your area.
