The conversion from conventional to low-input or organic crop production requires changes in pest control tactics. In a 5-year study, abundance of most pests did not change dramatically between conventional and low-input or organically managed systems, with a few notable exceptions. Organic and low-input plots suffered significantly greater damage from tomato fruitworm in 1989 and stink bugs in 1992. The major long-term effect has been on weeds. Weed control methods differ among the systems and have resulted in more barnyardgrass in low-input and organic systems and field bindweed and nightshade in conventional systems.
