Bio/Research

The overall approach is research that will contribute to integrated crop management of vegetable crops, with the focus on crop protection of vegetable crops. The crops of interest are root, bulb, leafy vegetables and crucifer crops, including onions, carrots, lettuce, celery, cabbage, Asian crucifer crops and some minor crops such as artichokes and chives. Plant pathology and disease management are major areas of interest. Collaborative work involving plant physiology, plant nutrition, plant breeding and entomology is also part of the approach.

Specific research projects investigate biological, cultural and chemical means of crop protection to discover the best approaches to crop management and how they interact with host resistance, plant nutrition, production practices, and other insect pests and diseases. Current projects include integrated crop management of Allium white rot on onion, with the emphasis on mycorrhizae as biological controls; biology and management of onion smut and interactions with onion maggot, nutrient management of carrot as part of an integrated crop management program with the focus on nitrogen utilization and the relationship to carrot leaf blight, epidemiology and management of sclerotinia rot of carrot, and soil amendments for the management of clubroot of crucifer crops. Efficacy testing of specific crop protection materials is conducted at the request of the industry. This program is GLP certified to do residue trials.
