No dust applications will be applied until payment has been received. Checks will be cashed when received, no postdates accepted. If application area is not clearly marked with flags (which we have available in our office, as well as, most county offices also) drivers will use best judgement when applying. This will be applied twice this season. The first application is usually Late May to Early/Mid June and the second in Late July to Early/Mid August. We recommend a minimum application of 400 feet, which has been proven to give the best results for dust control.
