Syngenta's Alto approved for soybeans in US

Syngenta has received US approval for the fungicide, Alto 100 SL (cyproconazole 100 g/litre), for use on soybeans. It is recommended for the control of Asian soybean rust ( Phakopsora pachyrhizi) and other diseases at 2.75-5.5 fl oz/acre (0.2-0.4 litre/ha). Alto provides curative activity against Asian soybean rust, but Syngenta recommends that it be applied as a preventive treatment in a tank mixture with Quadris (azoxystrobin). Alto received emergency exemptions for rust control in 2006 ( Agrow No 494, p 19).
