To aid you, the tree experts with Anderson’s Tree Care Specialists have crafted this handy guide to common tree pests and diseases in San Jose.

Identifying Common Tree Pests and
Diseases in San Jose

Timely identification of pests and diseases is critical to preventing extensive tree damage. The sooner the problem is resolved, the easier and faster it will be for your landscape to recover. Identifying tree pests and diseases promptly is vital to minimizing damage to your trees. A quick knowledgeable response will assist in a faster and smoother recovery.

Familiarizing yourself with these more prevalent types of tree pests and diseases is essential for early detection and effective intervention:

• Sudden Oak Death: A devastating pathogen-driven disease. It’s characterized by wilting and browning of leaves, cankers on the bark, and rapid tree decline. Early detection and management is crucial to minimizing the impact on forests and landscapes.
• Emerald Ash Borer: An invasive beetle native to Asia, this pest poses a grave threat to ash trees across the country. Its larvae tunnel under the bark, disrupting nutrient flow and causing tree decline.
• Spotted Lanternfly: This invasive pest can cause extensive harm to various trees and plants. Adult flies have bright red wings with black dots, while young ones may appear black with white spots in certain seasons.
• Deer: Deer often consume bark, twigs, and leaves. Their damage can leave trees vulnerable to disease and pests and hinder a tree’s growth and overall health.
• Winter and Gypsy Moths: Caterpillars pose a risk by devouring a tree’s leaves. While invasive, extermination efforts can reduce their prevalence.
• Needle Cast: A fungal disease affecting spruce, pine, Douglas fir, and true fir trees. Its spores spread from tree to tree, causing needles to brown and fall.
• Aphids: Aphids are small, soft-bodied insects that feed on the sap of trees and plants. Their feeding activities can lead to leaf curling, distortion, and yellowing.
• Web Worm and Tent Caterpillar: Webworms and Tent Caterpillars create silken webs on tree branches and at the ends of twigs. Infestations can stress the tree, potentially weakening its overall health and making it more vulnerable to other pests and diseases.

What are the Signs of Pests and Disease on Trees?

Accurate pest identification requires expertise, but you can detect initial signs of damage without specific knowledge. Prompt action can prevent the spread or worsening of these threats. If you observe any of the following symptoms, a professional arborist’s inspection is advised:

• Bite marks on leaves or wood
• Yellowing or dying leaves, needles, or branches
• Hollow areas in the trunk or branches
• Accumulation of sawdust or a fine powder on the ground
• Premature leaf shedding or failure to bloom
