|11733||QUINOA / MANDIPROPAMID||Downy mildew(Peronospora variabilis)
: Downy can negatively affect yields in Oregon quinoa plantings. There are no registered fungicides for use in quinoa to control this pest.
BB (HQ) needs an "A" priority to be evaluated at the FUW; easy "B" decision, have azoxystrobin and propiconazole via ChemSac no data petitions. (RS 8/18/15)
BB (HQ) there are no potential extrapolations for fluopicolide or mandipropamid and it would be helpful if they could be nominated for an “A” priority for downy mildew. Fluopicolide has been given the OK by the registrant with a request for crop safety and efficacy. Valent was initially concerned about rotational issues, but the information that Joe provided was very helpful in reversing their decision. Mandipropamid is under evaluation by Syngenta and is a good product for downy mildews. Fluopicolide has been used extensively on quinoa for downy mildew in Peru, so if I had to choose between the two, I would first go for fluopicolide and then mandipropamid. (RS 8/18/15)
PST CC: Mandipropamid an "A/B" but will defer to s-metolachlor for top priority in quinoa if clear path (RS 6/6/17)
