Why would you add toxins to your food? ~ Michael McNeill

(When asked whether it is appropriate to add foliar fertilizers to a spray mix which contained fungicides or insecticides.) 

It is fairly common to combine nutrients and biostimulants with toxic compounds in the same tank mix, but is this really what is best for plants?

Sometimes a combination is the only application logistically possible, but field experience suggests that separating foliar fed nutrients and pesticide applications will produce a bigger crop response to the foliar fed nutrients.

Foliar feeding in a combination with pesticides is better than not applying the needed nutrients at all. Applying nutrients and biostimulants without the toxins is best.
