New seed treatments and foliar fungicides
Just in time for the new crop year, a look at the new seed treatments and foliar fungicides and label updates for 2012, with product information provided by the manufactures.
Apron XL label update
Active ingredient: mefenoxam and ipconazole
Groups 4 and 12
A lower rate of 2.7 mL per 100 kg of Apron XL is approved for use when tank mixed with the label rate of Rancona Apex on wheat, barley, oat and rye for domestic use in Canada to provide pythium protection along with all the disease claims of Rancona Apex. Apron XL applied alone is approved at higher rate on wheat and only for domestic use on oats, barley and rye. The rate of mefenoxam applied to seed in this tank mix is identical to seed loading of mefenoxam applied to seed with Dividend XL RTA. Rancona Apex is a micro-dispersion formulation having properties providing more ease in obtaining uniform application.

Allegro label update
Active ingredient: fluazinam
New rate range of 0.6-1.0 L/ha registered on edible-podded legume vegetables (except pea) and dry shelled beans for control of white mold (sclerotinia sclerotiorum). For control of white mold make the first application at 10 to 30% bloom (e.g. when 10 to 30 percent of the plants have at least one (1) open bloom). If needed, a second application may be applied 7 to 10 days later. Under conditions favorable for severe disease development use the higher rate.
