    Q
    What rate on a hose end sprayer (per gallon of water) is needed for 3.6 oz per 1000 sq ft?
    I ordered a liquid pre emergent herbicide from you last week. I am applying with a hose end sprayer that is calculated at an application rate per gallon of water. The pre emergent says the application needs to be at 3.6 ounces per 1000 square feet. What does the setting on the hose end sprayer need to be?
    A
    The first thing you need to know when using an herbicide such as Pin Dee 3.0 T&O is that the exact amount of water you dilute it with is not important.  It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. 

    Pre-emergent herbicides are not recommended to be used in a hose end sprayer for the exact reason you described with the dilutation instructions on the label. 
    You will need to use 1.3 to 1.8 fl oz per 1,000 sq ft depending on your turfgrass. To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 1.3 to 1.8 oz of product with for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application

    Q
    Is Pin Dee 3.3 T&O Herbicide water soluble?
    Looking for pre-emergent crabgrass control. I looked at Pendulum, but noted one customer said he only uses the water soluble pendimethalin because it won't leave stains. So, I'm looking for a water soluble pendimethalin product.
    A
    Indeed Pin Dee is water soluble. For cool season grasses, you want to mix 1.3 to 1.8 Fl. oz Pin Dee with the amount of water needed to cover 1000 sq. feet. Please let us know if you have more questions.
