Fruit trees can be especially prone to fungal infections, diseases and insect infestations. Our pest control experts can spray the appropriate tree sprays to restore the health of your trees and keep them looking healthy.

When to Spray Your Trees

To keep your fruit trees healthy, you will need to follow a spraying schedule. This is based on the growing cycle of your trees and the threat that is threatening your trees.

Dormant Oil (Horizon or Horticultural Oil): Apply dormant sprays during November through March to control aphids, scale, spider mites and many other insects by desiccating their eggs and larvae. Mix with water and spray to all surfaces of the trunk, branches and twigs.

Insecticides: To help keep your fruit trees healthy, use a combination of a natural or synthetic insecticide and a fungicide. Synthetic fungicides are available in a trees spraying form, as well as in an injection for use in the tree trunk or limbs.

Botanical Insecticides: Often used as an alternative to chemical insecticides, botanical insecticides are organic and have no toxicity to bees or other pollinators. Insecticides that are a mixture of botanical ingredients are often more effective than individual chemical products alone.

Lime-Sulfur: A sulfur spray can help control fungal and bacterial diseases that are damaging to your fruit trees, including peach leaf curl, fire blight, anthracnose and scab. Lime-sulfur should be applied to apricots only if your trees are not currently exhibiting symptoms of disease and only after pruning, when the tree will be dormant for the winter.
