Infected leaves have to be eliminated, and the plant may be treated with a fungicide or a selfmade solution of baking soda and water to combat the mould.

Botrytis Blight (Gray Mold)

Botrytis blight is a fungal disease that flourishes in cool, damp situations. It reasons grayish mold to appear on leaves, flowers, and stems, often main to plant decay. This sickness is commonplace at some stage in wet seasons or while the plant is overwatered.

Signs of Botrytis Blight: Gray, fuzzy mildew on plant life, leaves, and stems, dying or decaying plant tissue, and darkened, wilting leaves.

Prevention and Treatment: Avoid overhead watering and make sure excellent air circulation. Remove any affected plant parts without delay and dispose of them well (don’t compost them, as this may spread the disorder). Fungicides can be applied to manage and save you the spread of Botrytis.

Leaf Spot

Leaf spot is due to diverse fungi or micro organism that result in small, darkish spots at the leaves. These spots might also grow large, and in intense instances, the leaves may yellow and drop prematurely.

Signs of Leaf Spot: Dark, circular spots on leaves, yellowing, and premature leaf drop.

Prevention and Treatment: Water the flowers at the base to keep away from wetting the leaves, and remove any inflamed leaves. Fungicides may be used to treat excessive instances of fungal leaf spot.

General Prevention Tips for Pests and Diseases

• Healthy Plants: Keep Nemesia healthful via providing it with the right growing conditions—well-draining soil, appropriate sunlight, and normal watering with out overwatering. Healthy flora are much less likely to attract pests and diseases.
