As of today there is nowhere in the PMRA Documentation that says using Fiesta 4 times a year is according to label directions.
Charbonneau has gone from 1 Application required (in order to get the pesticide ban in place and offer an alternative) to now 4 applications of Fiesta.
The label of course has always said 2 Applications per year only.

This is what Pam Charbonneau is suggesting for FIESTA herbicide treatments in ONTARIO.
There is no need to panic about applying the post-emergence herbicide Fiesta. It works best on a broad spectrum of weeds if two applications are made in the spring and then two in the fall.
