The plant becomes droopy, subtly discolored, and produces fewer flowers, eventually leading to its death, if not treated or prevented timely. It is caused by inadequate hydration to the plant roots.

Leaf tip withering

Leaf tip withering is a condition affecting Sulfur cosmos that results in the browning and dying off of leaf tips, which can progress towards the stem and compromise plant health.

Notch is a foliar disease affecting Sulfur cosmos, causing irregular-shaped lesions on leaves and compromised plant vigor. Highly contagious under certain conditions, it can lead to significant aesthetic and health impacts on Sulfur cosmos.

Leaf yellowing in Sulfur cosmos is a common condition characterized by the discoloration of foliage, which can lead to reduced growth and vigor. This condition may result from various factors including nutrient deficiencies, water stress, and diseases.

Leaf white mold

Leaf white mold is a fungal disease that causes severe damage to Sulfur cosmos leaves, leading to wilt, yellowing, and potentially plant death if untreated. It thrives in humid conditions and spreads through spores.

Leaf rot is a potentially devastating plant disease that affects the general health of Sulfur cosmos, causing leaves to wilt, yellow and eventually break off. Timely detection and treatment can significantly mitigate the detrimental impact of this disease.

Mealybug disease primarily affects Sulfur cosmos by sucking sap from their tissues, leading to stunted growth and leaf yellowing. This pest also excretes honeydew which encourages sooty mold growth, further harming the plant.

The disease 'Plant dried up' can be severely damaging for Sulfur cosmos, leading to wilting, discoloration, and eventual death. Caused mainly by improper watering and unfavorable conditions, it can impair the plant's growth and general vitality.

Leaf wilting in Sulfur cosmos is a detrimental condition that impedes plant growth and vigor, often leading to premature death. It's caused by various factors, from environmental stress to pathogenic infections, and results in the drooping or shriveling of foliage.

Spots on Sulfur cosmos are a common foliar disease, leading to discolored lesions on the leaves that can reduce photosynthesis and overall plant health if left unchecked.

Yellow edges is a disease affecting Sulfur cosmos, identifiable by the discoloration of its leaf margins, which can lead to reduced vigor and aesthetic value. The disease may be influenced by multiple factors such as pathogens, nutrient deficiencies, and environmental stresses.
