Pesticide preparations are made by mixing the exact quantity of pesticide with the appropriate amount of water. All information required describing the amount of pesticide to use is clearly described on the pesticide label. These instructions must be followed exactly. Be careful to mix only the amount of spray material that is needed. In general, sprays are applied to plant surfaces until all plant parts are thoroughly covered and spray material starts to drip from the treated surface. This is known as "spraying to run-off." Table 1 gives an idea of the amount of spray material required to treat fruit trees of different sizes.
Use the higher volume shown in Table 1 for trees in full foliage. Always begin spraying foliage in the top of the tree, and work downward to the lower branches. Keep in mind that larger trees present a greater chance for drift and accidental contamination of other areas.
Table 1. Approximate spray volume required for thorough coverage of fruit trees to the point of run-off
| Tree height (feet) | Spread of tree (feet) | Gallons of spray mixture per tree per application |
| 5 to 8 | 3 to 6 | 1 to 1-1/2 |
| 8 to 12 | 6 to 9 | 1-1/2 to 3 |
| 12 to 18 | 9 to 15 | 3 to 5 |
| 18 | 15 | 4 to 6 |
