1 Always read and follow all current
pesticide label instructions. If any information in these recommendations
disagrees with the pesticide label, the label instructions must be followed. Use
of a product name does not constitute product endorsement. All pesticides must
be registered with USEPA and the MDA. All applications of pesticides to
surface waters of the state and wastewater treatment facilities must be approved
by the MDEQ.
See
MDEQ Approval Process of Mosquito Control Projects.
