tall fescue, but it<br />

perennial ryegrass plots, control ranged<br />
from 73% to 94%, and 91% to 98%<br />
control in <strong>the</strong> Tupersan-treated plots.<br />
<strong>The</strong> hard fescue developed more<br />
slowly and thus was more heavily<br />
colonized by field paspalum. In hard<br />
fescue, field paspalum cover ranged<br />
from 22% to 50% in Tenacitytreated<br />
plots, whereas only 5% field<br />
paspalum cover (94% control) was<br />
observed in Tupersan-treated hard<br />
fescue. This may be <strong>the</strong> first report<br />
<strong>of</strong> preemergence control <strong>of</strong> field<br />
paspalum at spring seeding in coolseason<br />
turf with any herbicide.<br />
Conclusions<br />
Fusilade II may be a viable alternative<br />
to MSMA for postemergence control<br />
<strong>of</strong> field paspalum in tall fescue, but<br />
it has limitations. Interestingly, Dr.<br />
Jim Brosnsan (at <strong>The</strong> University <strong>of</strong><br />
Tennessee) reported in 2010 that<br />
Fusilade II applied just one time in<br />
early spring at 0.09 lb. ai/A (5.6 fl. oz.<br />
product/A) provided 90% dallisgrass<br />
control. Conversely, when Fusilade<br />
II was applied in early summer, <strong>the</strong><br />
level <strong>of</strong> dallisgrass control was poor.<br />
<strong>The</strong> Fusilade II label is somewhat<br />
vague on how to use this herbicide.<br />
<strong>The</strong> label simply states that Fusliade<br />
II is to be used for <strong>the</strong> suppression<br />
and/or control <strong>of</strong> common bermudagrass,<br />
hybrid bermudagrass and o<strong>the</strong>r<br />
grass weeds in zoysiagrass and tall<br />
fescue. It is not for use on home lawns.<br />
<strong>The</strong>re is no mention <strong>of</strong> any paspalum<br />
species being a target weed on <strong>the</strong><br />
