    Product Description

    Asulam is an herbicide.1 It inhibits wheat seedling dihydropteroate synthase (DHPS) activity by 70% in a cell-free assay when used at a concentration of 100 µM and decreases the levels of total folates in the shoot tips of wheat, wild oats, flax, and chickweed when applied at a dose of 1.1 kg/ha.2 Asulam (40% w/v) reduces the standing crop of bracken (P. aquilinum) fronds and the total biomass of bracken rhizomes.1 It has been found in spring water and honey.3,4 Formulations containing asulam have been used as herbicides in agriculture.

    WARNING This product is not for human or veterinary use.
