Quelex® herbicide improves productivity and keeps the land healthy with faster, more flexible control of broadleaf weeds.

Quelex is a selective post-emergent herbicide for use on all varieties of winter cereals and spring cereals for the control of key competitive broad-leaved weeds, including Galium aparine, Papaver rhoeas, Centaurea cyanus and Fumaria officinalis. It combines two active ingredients, Arylex™ active and florasulam in a GoDRI formulation.

Key Benefits

Unique mode of action and control spectrum

Quelex® provides advanced post-emergence control of many troublesome broad-leaved weeds including Stellaria media, Matricaria spp, Papaver rhoeas, Galium aparine, Brassica spp, Geranium spp, Lamium spp, Centaurea cyanus, Chenopodium album, Fumaria officinalis, Galeopsis tetrahit and Polygonum convolvulus. It includes two modes of action, making it another tool to help growers fight weed resistance.

Wide application window

Quelex® offers good selectivity over a wide window of cereal stages from BBCH 11 to BBCH 45 for autumn and spring applications. It offers consistent weed control across variable climatic conditions (cold or warm, wet or dry).

Ease of use

Quelex® rapidly disperses in cold water. It is easy to measure and there is less packaging left to destroy later. 

Quelex is rainfast one hour after application. It has high compatibility with tank mix partners, including grass killers.

Favorable toxicological & environmental profile

Quelex® degrades in soil and plant tissues rapidly, allowing for crop rotation flexibility. Low use rates of Quelex result in low environmental load of the herbicide.
