Diseases of Aglaonema

The disease most often attacks aglaonema are white flies.
The fix is, if aglaonema already mature enough to handle it can use insecticides. However, if the disease only affects a few leaves then use a little water mixed deterjent. Take a cotton bud, apply on the affected pest. Try to keep the water mixed with detergent that it does not drip in the planting medium because it can cause plants to wilt
