Bertha Armyworm can damage cabbage and broccoli crops in the Willamette Valley. This page provides some basic information about the pest and discusses management and controls methods. Detailed scouting and monitoring techniques are provided as well as a risk assessment for spray decisions.
The Black Cutworm & Variegated Cutworm can be particularly damaging to corn and bean crops in the Willamette Valley if infestations are not detected early. This page provides some basic information about the pest and discusses management and controls methods. Detailed scouting and monitoring techniques are provided as well as a risk assessment for spray decisions.
The Cabbage Aphid can cause significant economic loses in broccoli grown in the Willamette Valley (Figure One). The feeding of the aphid on the broccoli plant may reduce yield slightly, but the real damage it causes is contamination. The cabbage aphid contaminates the harvested heads of broccoli. This can result in rejection of entire loads of broccoli by the quality assurance program of broccoli processors. Once the aphids have moved up into the developing broccoli head, it is possible to kill them, but it is no longer possible to remove them as a contaminant.
The Cabbage White Butterfly can cause damage to several cole crops in the Willamette Valley. This page provides some basic information about the pest and discusses management and controls methods. Detailed scouting and monitoring techniques are provided as well as a risk assessment for spray decisions.
There are two common types of looper worms that infest crops in the Willamette Valley, the cabbage and the alfalfa loopers.This page provides some basic information about the pest and discusses management and controls methods. Detailed scouting and monitoring techniques are provided as well as a risk assessment for spray decisions.
