There are changes in the permitted use of chlorpyrifos or products containing chlorpyrifos, growers are being advised.
From April 1, 2016, the insecticide can only be used on protected brassica seedlings and applied as a modular drench through an automated gantry sprayer, according to the Chemicals Regulation Directorate.
Storage, disposal and relabelling of any existing stocks of products containing chlorpyrifos-ethyl must be completed by October 1, 2016.
As a result, Dursban WG and Equity, with the current uses on their label, cannot be sold after March 31, 2016, nor can growers apply theses products. These products have previously been available for use as egg hatch sprays for control of wheat bulb fly and also against leatherjackets in both cereals and grassland.
Growers are advised to use-up all Equity and Dursban WG on-farm before April 1, 2016, and avoid being left with opened packs after April 1, 2016.
