Viral diseases are not curable, so it is best to remove the infected plant parts and prevent the spread of the virus by cleaning tools before pruning.
Pests
Aphids: Aphids are tiny, soft-bodied insects that pierce the plant tissues and suck sap from the leaves, causing wilting and yellowing of the leaves. To control aphids, spray insecticidal soaps or oils or treat the plant with neem oil. Also, it is advisable to encourage natural predators like ladybugs and lacewings to feed on the aphids.
Whiteflies: Whiteflies are another pest that can be troublesome to Oldenlandia cana Bremek. They feed on plant sap, secreting honeydew that attracts sooty mold, leading to stunted growth and leaf yellowing. Use neem oil or insecticidal soap to control whiteflies by spraying it on the leaves' undersides. The yellow sticky traps can also help reduce their numbers.
Spider mites: These are tiny arachnids that damage the plant by sucking cell sap, making the leaves speckled and dull. To avoid spider mite infestations, keep the humidity levels high and the plant well-watered. If detected, treat the plant with insecticidal soap or horticultural oil sprayed on the leaves' undersides.
By keeping a close watch on the plant and being proactive in taking care of it, you can help prevent diseases and pest infestations from damaging it. Maintaining optimal growing conditions and promptly dealing with any problem that arises will ensure its healthy growth and blooming.
