The easy to use formulation of Sencorex Flow (metribuzin) has several new and useful Extension of Authorisation for Minor Uses (EAMU) to help out vegetable growers who have fewer and fewer herbicides to rely upon.
Vegetable growers have been plagued in the last few years by the loss of active ingredients, either as more products are revoked or go through re-registration and lose crops from their labels. But a residual herbicide, which is already the mainstay product in potatoes, has a number of new EAMUs for use in vegetables.
In addition to its label recommendations of first earlies, second earlies and maincrop potatoes and an EAMU in outdoor ornamentals, Sencorex Flow now has new EAMU’s for outdoor crops of asparagus, carrots, parsnips, celeriac, sweet potatoes and mallow.
For outdoor carrots, parsnips and celeriac (EAMU 0916 of 2015), Sencorex Flow is applied pre-emergence at a dose rate of 0.875 l/ha. Two applications can be made, with a 21 day interval between applications. Harvest interval is 4 weeks before harvest.
In outdoor asparagus (EAMU 0917 of 2015), it should be applied before the end of dormancy at a dose rate of 0.875 l/ha.
For outdoor sweet potatoes (EAMU 0915 of 2015) the maximum dose rate is 0.4 l/ha of Sencorex Flow. It can be applied pre or post planting but before shoots exceed 15 cm. Two applications can be made with a Maximum Total Dose of 1.15 l/ha.
Sencorex Flow is a 600 g/l suspension concentrate with a unique formulation that has been demonstrated to lift its efficacy to a higher level. With combined contact and residual activity, it controls the majority of common spring-germinating weeds, including most polygonums, mayweeds, small nettle, common poppy, speedwells and smooth sowthistle. It also has good grass-weed activity on black-grass, annual meadow-grass and rye-grass.
For any EAMU, growers should obtain a copy of the notice of approval via the Chemicals Regulation Directorate (CRD) web site, ADAS offices or NFU. In the EAMU notice of approval, CRD point out that liability lies with the user and growers are advised to test a small area of crop prior to commercial use.
