Product Description

Sultan is a residual herbicide which predominantly controls broad leaved weeds; however; it will also have some affectivity against grass weeds. It can be used around Ornamental Trees, Shrubs & Forestry. This makes it an ideal replacement for Ronstar which was taken off the market in 2014.

Apply as an overall treatment to the area using a knapsack or boom sprayer. New plantings can be treated after lining out or transplanting once the plants are established and sufficiently hardened off to withstand treatment. This may require irrigation before application which will also ensure adequate soil moisture. Apply 1.5 litres of Sultan in 220-450 litres of water per hectare. Use the higher water volume when seedbeds are less than ideal to ensure adequate coverage

Not all species or cultivars have been tested and so only a small number of plants should be treated initially to gain experience with the treatment. Selectivity it is greatest when applied under cool, overcast conditions. Applications should not be made to soft, vigorously growing foliage, particularly during or after a period of warm days and cold nights.
