Spraying Techniques for Fruit Trees
For best results, you must apply some pesticides to your fruit trees. The goal, of course, is
to get the best fruit with the least amount of chemicals. This guide provides some tips and
techniques for achieving this goal
Equipment
Unfortunately, most people lack the proper equipment. Most hobbyists have either a
handheld tank sprayer that required pumping, or a sprayer that fits on the end of a hose.
The pump sprayer applies chemicals accurately, and enables the proper mixing to be
done, but the range is limited and upper branches may be missed. Hose-end sprayers can
reach high up, but it is difficult to properly gauge the mix due to fluctuations in water
pressure. The mix of water to chemical is an essential factor, so we do not recommend
hose-end sprayers. Either use a tank sprayer (and stand on a ladder if needed), rent
equipment, or hire a professional to do the spraying.
Mixing
When mixing pesticides, make sure you follow directions exactly. Wear rubber gloves,
and any other protective equipment recommended on the package. Make sure you
measure accurately. Most pesticides come in powdered form, and require a certain
number of tablespoons be mixed per gallon. Do not use your kitchen measuring spoons or
cups; buy a separate set just for pesticides. Put the pesticide in the tank first, and then add
the water. Gauge the water amount by the marks on the tank. For a host sprayer, set the
adjustment on the sprayer for a certain amount of pesticide per gallon of water flow.
Spraying
It is important to cover all surfaces uniformly, while not overspraying. Leaves should be
wet, but not dripping. The larger the tree, the more difficult and time-consuming it will be
to spray. Well-pruned trees are easier to spray than more dense ones.
On a large tree, spray from the inside to the outside. Start with the trunk, and then spray
the outer branches from the inside. Then spray the outer branches from the outside. Small
trees can be sprayed on the outside only. On the outside, start at the top and spray
downward, working your way around the tree. Try not to overlap.
Stay away from the treated trees for the period of time specified on the pesticide
packaging. This can range from 12 hours for a week. Keep your family and pets out of
the area as well.
Cleanup
Clean the tank, sprayer, and all protective gear with clean water. Use soap on your
protective gear and rinse with running water, and then allow them to air-dry. Change all
