Hello, I've been going through process of starting a residential/commercial turf maintenance company( fertilizer, herbicide applications). While looking at sprayer options, I was asked the question of how many gallons per 1000, I would like to spray. I replied with two gallons, and was told that most people spray 4 gallons/1000. I am a golf course superintendent, and have pretty extensive experience in spraying. For the most part, most herbicides and insecticides have a range starting with 1 gallon per 1000. Fungicides usually specify for 2 gallons/1000. So I'd like to know what the train of thought of is going with 4. Seems like a lot of waste( extra towing weight, more frequent refills) I am in the Tampa area, maybe its a local thing? Thanks for your feedback.
