Pecan trees need to be treated because they can suffer from disease and insets. Pecan scab fungus is the main disease that affects the trees. It overwinters as a fungal material on leaves, shucks and stems which were infected the season before. When warmer temperatures and rainfall arrive, the fungal spores develop further and spread through the tree and to neighboring trees or orchards. Spraying can prevent pecan trees from falling victim.

Step 1

Buy a dormant fruit spray from a nursery or garden store. Plan to apply it in the winter, before spring buds surface.

Step 2

Lay a tarp over nearby plants such as perennials and evergreens. This will keep them from getting damaged.

Step 3

Check with a local pest control company to see if you can rent a high-pressure sprayer. This will enable you to reach the tops of the trees better.

Step 4

Measure the amount of water and solution directed on the bottle instructions. Secure the lid and shake the bottle. Pump the nozzle to get the solution mixed.

Step 5

Apply the spray from the top of the tree to the bottom. Work your way along the branches. Pump the bottle periodically to strengthen the spray.

Step 6

Spray until the branches are soaking wet. Lastly, spray the trunk.
