Properties

Studies on zebrafish have shown that benfuresate inhibits embryonic growth in this species and can induce malformations. These findings underscore the risks that herbicide exposure poses to aquatic organisms.^[1]

Uses

Benfuresate is widely used post-emergence to control grasses and weeds, for example in rice, fruit, bean, corn and sugarcane cultivation. Before crop emergence, it is applied to cotton and tobacco plants.^[2]

Benfuresate controls cyperus rotundus in cotton. Young shoots appear to be more sensitive to benfuresate than the roots. While treatment of the leaves with benfuresate has little effect, it causes severe damage to the treated bud.^[3]

Authorization

In the EU and Switzerland, crop protection products containing the active ingredient benfuresate are no longer authorized.

Benfuresate was authorized for use on cotton plants in Spain.^[4]
