Florasulam is a highly effective sulfonylurea herbicide used primarily for the control of broadleaf weeds in cereal crops such as wheat, barley, and rye. It works by inhibiting the enzyme acetolactate synthase (ALS), which is essential for the synthesis of branched-chain amino acids in plants, leading to the cessation of cell division and plant growth. It is commonly applied post-emergence and provides strong control against difficult-to-manage weeds like chickweed, mayweed, and various thistles. Due to its low application rate and high potency, florasulam is often formulated in combination with other herbicides, such as 2,4-D or MCPA, to broaden the spectrum of weed control and reduce the risk of resistance development. Its systemic action allows for translocation within the plant, ensuring effective control even on larger weed seedlings. Florasulam is valued for its favorable environmental profile, including low soil persistence and minimal impact on subsequent crops when used according to label instructions.
