Why Do Smoketree Suffer From Leaf White Mold?
Smoketree, also known as Smoke Bush, Venetian-Sumac, Wigtree, Young fustig, Hungarian Sumac, Purple Fringe
Leaf white mold is a fungal disease causing decay and significant loss of foliage in Smoketree. The mold primarily affects the plant's leaves, diminishing its vigor and aesthetic value, and if untreated, results in leaf defoliation.

Symptom Analysis

The disease begins with small, watery spots on the leaves of Smoketree. As the disease progresses, these spots grow larger, and a distinctive white, cottony fungal growth appears, leading to leaf withering and dropping.

When is Leaf white mold Most Active Period on Smoketree?

The mold thrives in high humidity and cooler temperatures, typical conditions of late spring and early fall. It is notorious for its macroscopic structures called sclerotia, which can survive in soil for extended periods, enabling the disease to spread annually.

Infectivity

The disease spreads rapidly as the fungus disseminates spores via the wind, so it can quickly infect a wide area of Smoketree plants.

Lethality

While not typically fatal to Smoketree, leaf white mold can weaken the plant extensively, leading to death if coupled with other stressors.

FAQs on Smoketree

What triggers the development of leaf white mold on Smoketree?
Leaf white mold is commonly triggered by humid, cooler weather, and poor plant circulation. Wet leaves and soil encourage the growth and spread of the fungal pathogen.
How long does it take for leaf white mold to damage Smoketree?
The speed at which the disease progresses can vary, but signs of damage (withered, mold-covered leaves) typically appear within 2-3 weeks of infection.
Is leaf white mold fatal to Smoketree?
While leaf white mold can severely weaken Smoketree, it is not typically fatal unless the plant is also subject to other stressors. However, substantial defoliation can result in the plant's death.
Can leaf white mold spread from Smoketree to any other plants?
Yes, leaf white mold can spread to other susceptible plant species, particularly those in close proximity and under similar environmental conditions.
Can leaf white mold reinfest in the same Smoketree
Yes, if the disease isn't entirely eradicated and the environmental conditions remain conducive, leaf white mold can reinfest the same plant.
What is the best way to prevent leaf white mold in Smoketree?
Proper spacing between plants, sanitation practices, and use of disease-resistant varieties are effective methods to prevent leaf white mold in Smoketree.
