November 17, 2014, Guelph, Ont – The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Royal MH-30® Xtra (maleic hydrazide) for control of sprouting of shallots in Canada. Royal MH-30® was already labeled for use on potatoes, onions and black tobacco in Canada.

This minor use project was sponsored by the Quebec Horticultural Council (CQH) in March 2013 as a result of minor use priorities established by growers and extension personnel in Canada.

The following is provided as an abbreviated, general outline only. Users should consult the complete label before using Royal MH-30®.

Advertisment

Royal MH-30® can be used for control of sprouting on shallots at a rate of 8.36 L per hectare in a minimum of 300 L water per hectare. Royal MH-30® should be applied when the bulbs are mature and have at least 5 – 8 green leaves. This application is often done when 50 per cent of the tops have fallen, but are still green; green tops are essential for the absorption of Royal MH-30®. Use one application per year and do not apply within 10 days of harvest.

Royal MH-30® is toxic to non-target terrestrial plants. Do not contaminate aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers.

Follow all other precautions and directions for use on the Royal MH-30® label carefully.
