Objectives:

1. Maintain, evaluate, and refine a regional pest monitoring network for selected Lepidopteran pests of broccoli and cauliflower, and other crops.
2. Develop new strategies for detecting aphid outbreaks.
3. Evaluate whether less aggressive spray programs are effective during periods of low insect pressure.
4. Compare the effectiveness of aphid and looper pesticides at various levels of insect pressure.

Objectives:

Determine-

1. the root rot tolerance and yield potential of sweet corn varieties
2. the relationship between rotational history and root rot potential
3. the relationship between soil factors and root rot potential
4. whether a cone tube bioassay can be used to screen fields for root rot potential

1. Irrigation level effects on sweet corn growth, yield, and root rot

2. Wild Proso Millet (WPM) control

3. Survival and emergency of WPM
