Description and Uses

Clodinafop-propargyl is a foliar-absorbed aryloxyphenoxypropionate herbicide which has the capacity to inhibit the lipid biosynthesizing enzyme, acetyl coenzyme-A-carboxylase.
Clodinafop-propargyl is a member of the Oxyphenoxy acid ester chemical class, which includes the active ingredients fluazifop-butyl, fenoxaprop-ethyl, diclofop methyl, quizalofop-ethyl and haloxyfop-methyl.

Clodinafop-propargyl is a member of the aryloxyphenoxy propionate chemical family. It acts as a systemic herbicide that acts on post-emergent weeds such as selected grasses. It does not act on broad leaved weeds. It is applied to the foliar parts of the weeds and is absorbed through the leaves. This foliar acting grass weed killer is translocated to the meristematic growing points of the plant where it interferes with the production of fatty acids required for plant growth.Grass weeds controlled include wild oats, rough meadow-grass, green foxtail, barnyard grass, Persian darnel, volunteer canary seed. It also provides moderate control of Italian rye-grass. It is suitable for use on the following crops – all varieties of wheat, autumn-sown spring wheat, rye, triticale and durum wheat.
