Mallet 2F Drench Calculator

Drench Calculation Instructions

To deliver the appropriate amount of Mallet 2F to each container, without allowing leaching out of the bottom, follow the steps below to calculate how much Mallet 2F stock solution to prepare, given your container size, number of containers to treat, and injector ratio used. Practice the application to get the appropriate volume per container delivered.

*Drenches should be applied to moist (not wet) soil, without allowing any leaching from the pot.

Note - Determining finished solution needed per container based on soil media and moisture levels at time of application: Experiment by adding various amounts of water to the respective container size to determine the appropriate amount needed to place the Mallet into the root zone without allowing leaching out the bottom of the container. Due to the variety of soil mediums and initial moisture contents, it is essential for each grower to determine this given their particular conditions.
