I have two questions.
1- I had a licensed applicator apply granular Trimec to kill some broadleaf weeds on a lawn. This was done 730 this morning. I told the customer not to water and keep foot traffic off of the lawn. The weather might be a factor (rain). How long should Trimec stick to a weed, possibly get washed off and yet still be effective? I realize that liquid is better but its a long story.
2- Im looking into getting a pest. lic. for next yr. Have all the info and test dates and material. What in your professional experience is a decent/good sprayer to apply herbicides. What size tank should I get if my lawns vary from 5-35k sq ft. I'll be sure to go with a Honda motor and a 300 ft hose. All input is greatly appreciated.
