Keeping Reno Trees Healthy

Here in Reno, trees face unique challenges in our desert climate, along with seasonal temperature swings and periods of drought. These conditions can weaken trees and make them more susceptible to disease, especially fungal infections that affect leaves, branches, and trunks. At American Arborists, we provide professional tree disease treatment in Reno, NV, with a strong focus on early detection, proven treatment methods, and long-term tree health management.

Our certified arborists specialize in treating foliar fungal pests and canker diseases using proven scouting methods and industry-approved fungicide treatments designed to support healthy, resilient trees for the long haul.

Professional Tree Disease Care for Reno’s Unique Climate

The climate in Northern Nevada creates a perfect environment for certain tree diseases to develop, especially when trees are already stressed by heat, cold, or inconsistent moisture in the air. It doesn’t take long for fungal pathogens to spread, leading to disease outbreak. Without professional evaluation and treatment, these diseases can lead to thin canopies, weak branches, and even tree loss.

American Arborists takes a proactive approach to tree disease care. Through year-round scouting and carefully timed treatments, we help property owners address disease issues early and protect the long-term value of their landscape.

Foliar Fungal Disease

Foliar fungal disease affects a tree’s leaves or needles and are one of the most common issues seen in Reno landscapes. These diseases can cause leaf spots, blotches, discoloration, curling, and premature leaf drop. Repeated infections can weaken the tree, reduce its ability to photosynthesize, and leave it more vulnerable to additional pests and stress.

Many ornamental and shade trees in Northern Nevada are susceptible to foliar fungal pests, especially during periods of moisture, heavy rain, or fluctuating temperatures. Early identification and treatment are key to preventing recurring outbreaks.

Foliar Fungal Pest Scouting

Our year-round scouting program allows us to detect early signs of foliar fungal pests before symptoms become severe. By monitoring tree health consistently, we can recommend treatments only when needed and ensure applications are made during the most effective windows.

Camelot O Fungicide Treatments

For the treatment of foliar fungal pests, American Arborists uses Camelot O Fungicide, a professional-grade product designed to protect foliage and suppress fungal activity.

Camelot O works by enhancing the tree’s natural defenses while helping control the spread of fungal pathogens. Treatments are carefully applied to ensure proper coverage and effectiveness without unnecessary impact on the surrounding environment.

Camelot O Fungicide treatments are available April through October, when trees are actively growing and most susceptible to foliar disease. Proper seasonal timing allows the fungicide to work with the tree’s natural growth processes for optimal results.

Canker Disease

Canker disease is a fungal infection that affects the bark, branches, or trunk of a tree. It often appears as sunken or discolored lesions and can cause oozing sap, cracked bark, or areas of dead tissue. As cankers expand, they can restrict the flow of water and nutrients, leading to branch death or structural weakness.

Canker diseases are especially concerning because they often spread quietly before symptoms become obvious. Without professional treatment, they can significantly shorten the lifespan of a tree.

Canker Scouting and Monitoring

Because of the way it affects the tree, canker disease requires a more specialized approach. American Arborists provides year-round scouting for canker disease, allowing our team to identify infections early and monitor their progression over time. This ongoing evaluation is essential for determining the best treatment strategy and minimizing long-term damage.

Phosphojet Fungicide Trunk Injection

For canker treatment, we utilize Phosphojet Fungicide trunk injections, a targeted method that delivers treatment directly into the tree’s vascular system. Trunk injections allow the fungicide to move systemically throughout the tree, reaching infected tissues more effectively than surface applications. Phosphojet helps suppress fungal activity and supports the tree’s ability to defend itself against disease progression.

Phosphojet trunk injections are available during specific months when trees can best absorb and distribute the treatment. These treatments are offered in April, May, June, September, and October, aligning with optimal physiological conditions for injection success.

The Importance of Seasonal Tree Disease Management

Tree diseases do not follow a one-size-fits-all schedule. Their development is closely tied to seasonal conditions, tree growth cycles, and environmental stress.

By combining year-round scouting with seasonally appropriate treatments, American Arborists helps ensure diseases are addressed at the most effective times. This approach reduces repeat infections, supports tree recovery, and improves overall landscape health in Reno’s challenging climate.
