Infection of cucumber and blackeye cowpea with tobacco ringspot virus (TRSV) was not affected by benomyl seed treatment. Feeding access to cucumber grown from benomyl treated seed killed or inactivated Xiphinema americanum and its ability to transmit TRSV was almost eliminated. Nematode transmission of TRSV to treated bait plants was also greatly reduced. Powdery mildew was controlled.
