J. 83:413-417 (1991) From ab4el.com Sun Jul 17 00:00:00 1994 Subject: ABSTRACT "ABSTRACT "To efficiently use postemergence herbicides, decision makers must determine when weed populations exceed economic treatment thresholds. An interactive microcomputer program named HERB has been developed to help evaluate potential crop damage from multi-species weed complexes in soybean [Glycine max (L.) Merr.] and determine the appropriate course of action. Seventy-six weeds species are rated on a scale of zero to 10 according to their competitiveness with soybean. Potential yield loss is estimated from these rankings, the number of weeds of each species present in the field, and expected weed-free yield. The recommendation whether to apply herbicide and, if so, which one, is based on herbicide cost and efficacies under different conditions and expected soybean selling price. Alternative choices are ranked according to expected net return. HERB is intended to provide the latest research information in an organized and easily usable form. The approach should be applicable to other crops and pests." HERB(r) is a registered trade mark of North Carolina State University.

The main bullets under Design Considerations are: The software does not attempt to relieve the decision maker of the final decision. The software performs a necessary and important task which is tedious, complicated, or time consumimg.; The software represents an expert on immediate call for seasonal decisions. Decision support software for personal computers provides a medium for the transfer of the latest research results directly to the end users who might benefit most. The use of HERB supports and encourages appropraite levels of herbicide application. The decision maker can make an independent assessment in private. HERB may be a generic framework for extension or other crops and pests. Anyone who might be interested in obtaining a reprint of this article should send my their mailing address. HERB is a software application based on *applied* plant biology. From ab4el.com Sun Jul 17 00:00:00 1994 Subject: Send reprint request to... Request a reprint from: Dr. G. G.
