Summary:
Objectives: Outcomes and Impacts Summary from 2001 IPM Center report The 13,000 acres of lima beans grown in Delaware alone are worth nearly $5.5 million annually. Although weeds are a major concern for lima bean producers, growers have very limited options for weed control. VanGessel and his colleagues evaluated a comprehensive IPM system for lima beans that considered the impact of weeds on crop yield and quality. They explored strategies for maintaining acceptable weed control while reducing the amounts of herbicide by one-half the normal rate. They found that a viable alternative in lima bean production is to switch from a chemically intensive system to low-use-rate system complemented with mechanical cultivation. Under some conditions, their system allowed them to reduce the amount of herbicide applied by 84 percent while still maintaining effective weed control. |
