Cabbage Maggot Control Using Entomophagous Nematodes, 1987

The plot was transplanted and treated 5 Aug by hand at our research farm near Geneva, N.Y., in a Lima silt loam soil. Plots consisted of a single row, 20 ft long, replicated 4 times in a randomized complete block. Insecticide applications were based on a 36-inch row width. Nematode treatments consisted of both fresh and dessicated nematodes. Nematodes were counted using standard dilution techniques. Drench applications were applied at 65 gal/acre to the soil surface after planting using a CO2 powered sprayer. Transplant applications were applied at 613 gal/acre (200 ml/plant). Injury ratings were made 20 Oct by pulling 10 roots/plot, washing them, and counting the number of tunnels present.
