Thinking about investing in a ride-on spreader/sprayer, but I have a few questions for those of you who use them. I should also say, I'm not looking for advice on what brand to buy. 1. Do you spray fungicides from them? If so, how effective are they? I'm a little worried about low volume and fungicides. Before anyone starts giving me advice on a program, fungicides are part of my program. St. Augustine on the Gulf Coast, no way around it. 2. Does anyone use foam markers? I'm concerned that I won't ALWAYS be able to see my tracks and that my overlap is going to be less than perfect. 3. How much of a problem is drift? It looks like the nozzles are pretty low and I'm assuming everyone runs AI nozzles? Wind is always an issue in my area. 4. Does anyone spray micros from their ride-ons? If so, what is your carrier rate/1000? Thanks in advance for your input.
