Full Description

Sultan 50SC is a residual herbicide for the pre- and post- emergence control of broad-leaved weeds, however it will also have some effect against grass weeds. It can be used around ornamental trees, shrubs and forestry making it an ideal replacement for Ronstar which was taken off the market in 2014.

Apply Sultan 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.

Sultan will provide effective control the following weeds: chickweed, red dead-nettle, forget-me-not, mayweed, annual meadow grass, parsley piert, speedwell & sheppard's purse. It will also provide a degree of control against cleavers, cranesbill and poppy.

Some of the below list may be treated with an overall spray. 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.
