I use to cut water rates on all crops and was having weed problems since have gone back to 10gal on peas and canola. Been using Viper for a few years and been spraying 10gal.
We have used 4 gal for 3 years now with no issues. Remember coverage is more important than water volume. Bump up your pressure (60lbs) and dont spray in a wind and you will do a better job. Get them sprayed before six nodes is also important.
