Australia to approve Nippon Soda’s new fungicide ipflufenoquin

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has before it an application for the approval of Nippon Soda’s new active constituent, ipflufenoquin. Ipflufenoquin is a fungicide with both quinoline and phenylpropanol functionalities, for use in agricultural products.

The APVMA is also considering to approve the new product MIGIWA Fungicide, containing 218 g/L ipflufenoquin, as a suspension concentrate formulation of the new active constituent ipflufenoquin. This application was submitted by AgNova Technologies Pty Ltd.

Ipflufenoquin is a novel broad-spectrum fungicide and belongs to the class of quinolines. It is proposed to be a member of the inhibition of dihydroorotate dehydrogenase within de novo pyrimidine biosynthesis, group (Group 52) of fungicides (DHODHI) as designated by the Fungicide Resistance Action Committee (FRAC).

MIGIWA Fungicide is intended for the control of grey mould (Botrytis cinerea) in strawberries, in both field and protected cropping situations. Proposed application methods are by boom sprayers in the field and either directed vertical sprayers or handheld sprayers in protected environments. Application rates are either 25 mL/100 L in a maximum volume of 1,200 L/ha or 250 mL/ha when spray volume is 500 to 1000 L/ha, with no consecutive sprays and a maximum of 3 applications per fruiting season with a 7-to-10-day interval between applications. MIGIWA Fungicide is to be applied before first sign of disease or when conditions are conducive to disease development.

The active constituent ipflufenoquin is currently registered in the USA for use on pome fruit and almonds. Registration of ipflufenoquin products for use in strawberries is currently being sought in several other countries, including the USA, Japan, and Europe.

Public comments to this proposal will open before 14 February 2023.
