Controlling Eurasian Milfoil
SePRO brings us two new technologies to fight Eurasian Milfoil
Sculpin Herbicide will be a granular formulation of 2,4D amine. While 2,4D herbicides have long been
used for selective Eurasian Milfoil control in lake and river systems, the only granular formulation
available to applicators for years has been the BEE formulation. Having an amine granular formulation
will allow us to improve the contact time necessary to gain control of this noxious invasive weed in waters
where this chemistry is the best option for control.
The second product announced is Renovate MAX G (granular). Renovate is another selective herbicide
that is target specific for Eurasian Milfoil. It has been used very effectively throughout the northern
United States for a number of years to provide long term control of this invasive aquatic weed. With the
advent of projects with smaller and smaller colonies of milfoil, more difficult to control hybrid forms of
Milfoil and more difficult to control situations, SePRO developed Renovate MAX G as a combination of
triclopyr and 2,4D amine herbicides that are optimized to improve control over either of these products
used alone. This technology should dramatically improve long term control of this weed throughout the
region.
As part of that commitment to the environment, SePRO has developed a biodegradable granule as the
controlled release carrier for both of these herbicides. Most other granular carriers are clays that have
to be mined from the earth and transported to manufacturing and then to the field. Using this completely
biodegradable technology, the mining and transport to manufacturing step is removed and nothing is left
in the environment after delivery of the herbicide to the target species.
Milfoil Weevil
A new bug may be on the way to fight Eurasian Milfoil in lakes. The milfoil weevil could be an answer to
chemical treatment for the invasive weed that has choked many lakes. The weevil is a specialist
herbivore and will be studied for six years by researchers from the University of Wisconsin-Stevens Point
at Lake Joanis. If the study goes well the weevil could be released in other lakes to fight invasive weeds.
The weevil may be native to your lake which would mean that you don't have to wait for testing.
