David from Tulsa, Ok writes,

What is meant by "Cumulative shrub height" on the Criterion 75 WSP Systemic Insecticide label?


Cumulative feet of shrub height is the total height of all shrubs to be treated. This is determined by estimating the height of all individual shrubs in feet and totaling the sum. With this information, you can correctly mix the appropriate amount of Merit needed for the shrub or foliage plant application.

Example: If you have two shrubs that are 2 feet in height and one shrub that is 5 feet in height you would have 9 feet of cumulative shrub height. Measure the Criterion 75 WSP according to the instructions above and apply to the individual shrub according to its own height. For instance if you decided to use 1 gallon of water per foot of shrub height, the shrub that is 5 feet in height would receive 5 gallons of diluted Criterion 75 WSP solution and the shrubs that were only 2 feet in height would receive 2 gallons each of the diluted Criterion 75 WSP solution.
