Abstract:

Control studies were conducted on the western bean cutworm, Loxagrolis albicosta (Smith), in field beans in heavily infested areas of western Nebraska during 1958, 1959, and 1960. Because infestations vary from field to field, it was necessary to determine injurious population levels.

In all three tests SevinĀ® (1-naphthyl N-methylcarbamate), endosulfan (formerly known as Thiodan), and DDT gave good control. Aldrin as a soil treatment provided some control, however a combination of soil and foliage treatments was no better than foliage treatment alone. Other chemicals tested gave fair to poor control.

The tests conducted in 1959 and 1960 to determine injurious population levels indicated that populations slightly above 1.11 cutworms per square foot caused a reduction in grade of the beans. The total yield was not affected by the feeding of the cutworm.
