Leafminer and aphid infestations on celery were quantified and novel management methods were evaluated.
Potato tuberworm and other soil-borne insects are pests of this crop in parts of California. Extension activities have continued as needed.
Sugarbeet production used to be widespread in California and much of it was near the Davis area. Insect pests are very common and damaging on this crop. Aphids, leafhoppers, and beet armyworm, in particular, can be detrimental to yields. The aphids transmit virus diseases which intensifies the injury. Several graduate students and SRAs in my laboratory conducted research in this system. Presently, sugarbeets are only produced in the Imperial Valley (near the California-Mexico border - some 600 miles from Davis) so this research has been discontinued.
The fit of GMO sweet corn for managing corn earworm was evaluated and compared with the traditional method of repeated foliar insecticide applications.
Wild rice is grown in the Sacramento Valley intermingled with and grown similarly to the white rice production. However, wild rice is also grown in the Fall River Valley and grown more similar to the traditional wild rice production. Midges and tadpole shrimp are key pests of wild rice. Studies on management of these pests have been conducted as requested and as needed.
