Leaf spot causes the leaves to develop brown-black spots, while powdery mildew looks like a white powdery coating on the leaves.
To manage these fungal diseases, you should first cut off all infected parts of the plant and dispose of the debris in a safe manner. You should then adjust your watering routine to avoid overwatering, which can encourage the growth of fungal spores on the leaves. You can also use fungicides that are readily available in garden stores to spray on the plants as directed. It is best to take preventive measures and keep the plant healthy by providing good air circulation and avoiding overhead watering.

Commelina weimarckiana Norl. can be attractive to several types of pests, such as spider mites, mealybugs, and thrips. Spider mites are tiny pests that feed on the leaves, causing yellowing, wilting, and webbing. Mealybugs are small white insects that move slowly and feed on the plant's sap, causing stunted growth and yellowing of the leaves. Thrips are also small insects that feed on the leaves, causing scars and feeding damage.
To manage these pests, you should first isolate the infected plant to avoid the infestation spreading to other plants. You should then spray the plant with an insecticidal soap or oil as directed to kill the pests. You can also use sticky traps to catch the pests. You should also regularly inspect the plant for any signs of pests to catch and treat any infestation early.
