2013 Annual Report

1a. Objectives (from AD-416):
To establish the feasibility of utilizing anaerobic soil disinfestations on a large-scale in a methyl bromide-dependent crop.

1b. Approach (from AD-416):
Large-scale demonstration trials will be established in commercial caladium production. The grower cooperator will establish the trials using treatments guidelines provided by the ARS researcher.

3. Progress Report:
This research is related to inhouse project objective: 2. Integrate cultural, biological, and chemical control tactics into technically feasible pest management programs for soilborne pests and pathogens. In the large-scale caladium demonstration, anaerobic soil disinfestations (ASD) was conducted on raised beds with opaque film rather than with a solarization period. There was a one-day delay between the application of the amendments and soil saturation. Based on the grower yield data, ASD plots yielded approximately 50.5% of those treated with methyl bromide. In the second demonstration trial, a single plastic application was made in one lateral using clear solarization film and a white/black opaque film in the second lateral. The crop, Colocasia esculenta did poorly produced on clear plastic, but grew as well in the opaque film as in the adjacent fumigated block.
