NON-SELECTIVE HERBICIDE

  Customers will ask for a "weed killer" - Prequalify where the weed is and what type of weed.
Question to ask Customers 1. Will this be on dirt, driveways, lawn or flower beds?

Products labeled Non-selective means it's going to kill everything it contacts so this is the wrong product to sell them for weeds in the lawn.

Find out what they are using to spray the product - sprayers need to be adjusted so they do not mist or overspray desireable plants and vegitation.

Direct the customer to this web site for details on calibration and applicatrion they can review when they get home and actually start spraying the product you sold them.
