Arizona now has a section 18 provision for Topguard in cotton for root rot. Cotton root rot occurs in all the cotton growing areas of Arizona. Several are severely affected by cotton root rot and may limit cotton production including the Safford Valley, Marana to the Santa Cruz flats areas south and east of Eloy, and areas around Florence. Topguard will be used as a soil applied fungicide at planting to control root rot of cotton caused by the fungus Phymatotrichum omnivorum.
