Texas is no stranger to winter weather, especially the Panhandle and South Plains. While most trees will go dormant during this time, some are still vulnerable to insects and disease. Winter affords Arborists an opportunity to use tools, methods, and treatments not available during the growing season.
Insect control can be tremendously effective during this time. Dormant oils and systemic insecticides can be applied.
Aphids effect ornamental plants, evergreens, and deciduous trees. Ladybugs love aphids and are oftentimes a good indicator of an Aphid issue during the growing season. Black Aphids are very active in pines during the cooler months and can even be active during warm spells throughout the winter. Dormant oils can be especially effective during the winter to smother eggs and prevent infestations before they hatch. Systemic insecticides may also be applied during winter months to deter pests once spring arrives.
Scales often go unnoticed due to their appearance and method of attachment. There are 2 main types of scale insects: soft and armored. Soft scale insects secrete a waxy film which protects them from insecticide sprays. Armored scale insects live under a protective hard shell. Both types attach directly to the tree and are challenging to combat even while active. The winter months provide an opportunity to treat the scale without harming beneficial insects. Systemic insecticides and dormant oils are useful tools.
Pine Tip Moth
Pine Tip Moth larvae feed on the new growth, primarily on Pine trees, in early spring. Insecticide sprays during this period can be extremely effective with minimal collateral damage to beneficial insects.
Chlorosis is a severe mineral deficiency, often resulting in untimely yellowing and decline. This disease plagues many of the non-native trees in our region. Pears, Maples, and certain varieties of Oak are particularly susceptible. While we can treat during the growing season, dormancy allows for a direct injection of mineral supplements at high rates that will increase the effectiveness and longevity of the treatment.
Lubbock residents know all too well the effects of Oak Wilt. Preventative treatments can be injected year around however pruning is only recommended during the cooler months. Reduced insect activity all but eliminates the likelihood of transmission from tree to tree through open wounds.
