If you're using the pump sprayers, you will be able to more accurately determine the mixing of the chemicals. Unfortunately, you won't be able to spray it very far. Usually it wonít reach the tops of trees. This can be achieved with the hose end sprayers, but getting the correct mix of chemicals is quite a challenge. It all depends on your water pressure to get the correct mixture of chemicals, but water pressure is not constant. One day it might be lower, in which case your chemical content would be higher. The types of materials you buy for hose application are generally in an extremely strong form. They need to be severely diluted before they are weak enough to apply.
When you are mixing the chemicals for spraying
Now comes the spraying. The goal is to spray the same amount over all the areas. You still donít want to spray so much that enough builds up to drip off of the leaves. Usually you will want to get a ladder so that you can get within spraying distance of all the portions of the tree. Apply the pesticide in even, full sweeps as to hit every piece. Never go over the same part twice, because that is when you start to drip.
If you're dealing with a large and well developed tree, you should stand on a ladder under the base of the trunk. Spray all segments from the inside towards the outside. After you are done spraying the outer canopy, youíre ready to get out from under there and work on the rest. Once you are done cleaning, be sure to fully and thoroughly clean off every bit of equipment you used, including your clothes. Don't include the clothes you wore while spraying in the rest of your familyís laundry.
While you're spraying for pests, the main thing to keep in mind is to avoid dripping onto the ground. When this happens, the pesticides will be absorbed
