High-volatile ester formulations of 2,4-D (ethyl, butyl and iso-butyl esters) can be used between 1 May and 31 August. They should not be sprayed within 1.5 km of grapevines or other susceptible crops. All users must make and keep a record of any application of high-volatile 2,4-D ester within 24 hours of completing the application.
Low-volatile and non-volatile formulations of 2,4-D can be used at any time of the year, provided that all label directions are followed. All 2,4-D products must be applied when the wind speed is 3–15 km/hr, as measured at the application site, and droplet size must not be smaller than coarse to very coarse according to the ASAE S572 definition for standard nozzles.
