Product Overview

Valdor® Flex is a residual, pre-emergent, herbicide that controls a broad spectrum of weeds.

When applied prior to germination, depending on the weed species to be controlled, Valdor® Flex keeps the soil weed free for up to 4 months. The product is a combination of 2 active ingredients, Iodosulfuron-methyl-sodium and Diflufenican (DFF), in convenient pack sizes. These active ingredients complement each other and improve the result compared to being applied individually.

Valdor® Flex can be applied to all permeable surfaces and railway ballast to provide effective weed control in a number of environments from industrial sites to publics spaces. If weeds are present Valdor® Flex can be applied with glyphosate or a fatty acid to achieve control of existing vegetation.
