Surveys indicate this is the third most troublesome weed in peanuts.

摘要

Recent surveys in Georgia show that tropic croton {Croton glandulosus var. septentrionalis) is the third most trou-Jblesome weed in peanuts and fifth most troublesome weed in cotton. The increase in its prevalence in Georgia can be attributed to several factors including a change in herbicides, particularly the loss of dinoseb in 1986, and the fact that many standard herbicides currently used in peanut and cotton are ineffective on this weed. Also, mature seeds are forcibly discharged from the plantand are readily eaten by birds, which facilitate dispersal and spread.
