    I have been spraying speedzone broadleaf (red label). The temps are starting to rise and I am trying to figure out when to move to trimec 992. What air temp do you guys switch. All the label says is spraying when it is too hot which is a no brainer, but I know that trimec is better when the temps rise as opposed to speedzone because of the salt.
