Lima Beans, Corn Earworm Control, 1977

’Bridgeton’ lima beans were planted in double row plots, 40 ft in length, on July 8, 1977. Each plot was buffered on either side by 2 untreated guard rows. The distance between rows was 3 ft. The treatments were arranged in a randomized complete block design with 4 replications. Spray treatments were applied on August 31, September 13, and 19, with a wheelbarrow-type sprayer using CO2 for spray discharge. The spray boom was equipped with drop nozzles and each row was covered by 3 nozzles. All treatments were mixed with 1.5 gal of water and applied at the rate of 25 gal/A with 40 psi. Plots were rated on September 27 by harvesting 100 pods/treat/rep and recording the percent pods with com earworm injury. Yields were taken on October 4 by harvesting 2, 10-ft sections/treat/rep. The beans were run through a commercial viner and the pounds shelled weight were recorded.
