Why Spray Trees?
The control of tree disease pests and insects on your trees often results in the need to spray. Tree trunk injections and/or soil injections can sometimes work but more often spraying is the answer. Tree spraying can be divided into two categories: Preventative tree sprays and curative tree sprays.
Preventative Tree Sprays
Preventative tree sprays are used when a tree service or arborist is trying to stop damage from a tree disease, insect or other pest. This type of spraying is applied just prior to when the threat is anticipated to arrive or become active. For example, if you are attempting to stop a tree disease that will affect the leaves then a preventative tree spray is scheduled. Almost all insect pests can be controlled using preventative tree sprays.
Curative Tree Sprays
Curative tree sprays are used when the tree insect, pest or disease are already present. If an insect has already started to feed on the tree a curative tree spray can stop the insect from causing too much damage. The population of insects and pests can fluctuate from one season to the next so there may not always be a need to spray a tree/shrub annually. However, in other cases the damage is almost certainly going to occur if the tree isn’t sprayed annually. This variable is generally dependent on the tree species. A local tree service or arborist will be able to let you know what you have in your landscape that’s at risk of common attacks, as well as, instruct you how to handle the situation.
The purpose of targeted tree sprays is to control a certain insect or disease at a specific time of the season. With this method, only one tree or perhaps one tree species is targeted and sprayed. For example, Apple Scab disease attacks crabapple trees, then only the crabapple trees in your yard will be sprayed.
Spraying trees can be controversial, but the bottom line is that without spraying your trees could be at risk of being seriously damaged or killed.
