Root-knot nematodes ( Meloidogyne spp.) are a major group of pathogens of tobacco. Farm management decisions are typically based on a systems approach where agricultural pesticides may be targeted at several pests. The economic benefits of a pesticide needs to account for the complexity of the pest populations, and the multiple pest targets of a pesticide. Populations of insects such as: wireworms, cutworms, flea beetles, aphids, budworms, and hornworms, are endemic in tobacco fields in the USA and present considerable control cost for producers. Economic analysis of the benefit of 1,3-D for nematode control and it's comparison with nonfumigant nematicides with insecticidal attributes were evaluated over a two year period. The insecticidal properties of the soil insecticide/nematicides could be compared among treatments because wireworms and budworm were observed during1993-94. Application of soil insecticide/nematicides such as ethoprop and chlorpyrifos reduced wireworm damage when compared to an untreated control and when used at lower insecticide rates in combination with 1,3-D. Carbofuran reduced the number of foliar insecticide sprays required to control the insect populations. Although nonfumigant nematicides provided some insect control, the cost of using a fumigant in concert with an insecticidal rate of a soil insecticide/nematicide was comparable to the least expensive non-fumigant nematicide when the cost of foliar insecticide applications was included in the cost estimates.
