In order for Michigan onion growers to remain competitive and produce a quality product, it
is imperative that the following pesticides be retained until effective and cost efficient
pesticides are identified and registered:
• Fungicides: chlorothalonil (Bravo, Echo, Equus), mancozeb (Dithane, Manzate,
Manex II, Penncozeb), maneb (Manex), iprodione (Iprodione,
Rovral).
• Insecticides: chlorpyrifos (Lorsban), methomyl (Lannate), pyrethroids (Ambush,
Ammo, Pounce).
• Herbicides: oxyfluorfen (Goal), pendimethalin (Prowl), s-metolachlor (Dual
Magnum), bromoxynil (Buctril) , sethoxydim (Poast), fluazifop-p
(Fusilade), clethodim (Select). |
