I am in need of some pesticide recordkeeping software. I need one to keep an inventory of what pesticides and fertilizers I have and also to keep a record of what has bee sprayed. Do any of you know of one that can keep records for spraying out of a 100 gallon sprayer and also out of 3 gallon backpacks. Most I have seen don't figure in rates as small as 3 gallon. Thanks.
