http://golfsupersdelight.x10host.com/cgi-bin/PesticideCostCalculator.htmlI posted this on here before and got a limited response. I've had a little over 700 hits on the site but things have tapered off and I'm not sure why. It's completely free and there is no advertising or anything. I also added a fertilizer calculator. I know it's been useful for me as a superintendent and I'm sure it will be for many others if they want comparable data between different pesticides and different modes of action. Please try it out and let me know if there is a way to improve it.
