In 1977, American scientists from the University of California at Davis reported the control of Verticillium in a cotton field, based on studies started in 1976, thus denoting, for the first time, the possible wide applicability of this method.
Identification can be made by looking for one-celled conidia, hyaline round to ellipsoid which are formed at the tips of whorled branches.
Wilt disease can follow when opportunistic fungi such as Fusarium and Verticillium infect the plants, a process observed in cotton.
