W. P. Law, Incorporated - Fluid Handling Professionals
Our Turfgrass Chemical Selection Guide is designed to help users identify chemicals that are labeled for controlling specific weeds, insects, and diseases for various grass types.  This guide is intended to be a starting point in order to  search for chemical control options available.   Choose the type of pest at the top of the guide (disease, insect, or weed).  Next, choose your grass type and then the specific pest you want to control.

Once you have completed all the required fields for the Turfgrass Chemical Selection Guide, a list of labeled chemicals will be compiled for you.  For your convenience, the product label is available to provide very detailed information about each chemical.  Please refer to the product label to determine if it appropriate to use for your particular situation.  Due to varying factors, not all of the labeled chemicals may fit your exact situation.  Please refer to the label or consult your local W.P. Law Inc. office for additional information and advice.

Our Turfgrass Pre-emergent Herbicide Calculator (found within the Turfgrass Chemical Selection Guide) is designed to help users calculate how much pre-emergent herbicide they will need to cover their property.  Users can choose between various formulations of pre-emergent herbicides to help calculate the amount they will need.  By entering the container size or weight, percent active ingredient, and pounds of active ingredient needed per acre, the calculator will determine how much product is needed per acre or per 1,000 square feet.

Once the amount of pre-emergent herbicide needed has been calculated, users can enter the price of the product to determine how much it will cost per acre or per 1,000 square feet.   For comparison purposes, two calculators are available if users want to examine different brands of pre-emergent herbicides.
