US exemption for Cheminova's Topguard
The US EPA has granted an emergency exemption to allow the use of Cheminova’s fungicide, Topguard (flutriafol), in Texas to control cotton root rot ( Phymatotrichum omnivorum). The exemption takes effect on February 1st 2013 and expires on June 30th 2013. Up to 288,000 acres (117,000 ha) of cotton may be treated with the fungicide. It is the second year that the exemption has been granted. Cheminova received US approval for the use of Topguard on soybeans and apples in 2010 ( Agrow No 591, p 27).
