Celery growers have a limited selection of products, which makes it difficult to manage
resistance as their choices for rotation narrow. In order for Michigan celery growers to
remain competitive and produce a quality product, it is imperative that the following
pesticides be retained:
! Fungicide: Bravo (chlorothalonil - broad spectrum, cost effective: nothing currently
available compares with its efficacy).
! Insecticides: Lannate (methomyl - broad spectrum, cost effective), Vydate (oxamyl -
only product registered for carrot weevil, important for nematode control), Orthene
(acephate - systemic, broad spectrum), Ambush/Pounce (permethrin - broad
spectrum, fast acting, short PHI).
! Herbicides: Dual Magnum (metolachlor - suppresses nutsedge and annual grasses),
Lorox (linuron) and Caparol (prometryn) (both are broad-spectrum and are versatile
with pre- and post-emergence use). |

For the reasons stated previously, it is important that registration of the following
products be expedited:
! Fungicide: Topsin-M (thiophanate-methyl) to fill the gap left by the cancellation of
Benlate (benomyl), which was an important tool in halting disease once it had started.
! Insecticide: Provado (imidacloprid) has the same active ingredient as Admire but is
less expensive. |
