For a number of years, California cotton growers have had access to a powerful computer program that integrated most of the information they needed to make good management decisions. The overall objective of this project is to develop a similar "expert" system for California rice management.

A development team consisting of several knowledgeable rice scientists and advisors has programmed a basic expert system for integrated rice management. A module for weed control has been completed. The module permits the user to select the best herbicide or combination of herbicides for a given weed problem, and to see which weeds are best controlled by a given herbicide.

Work is nearly complete on a variety description and selection module. This module will provide information on the principal characteristics of varieties and rank them based on the grower's needs. For instance, the maturity criterion takes into consideration planting date cutoff, appropriate growing regions and other factors.

The prototype expert system is scheduled to be distributed to Cooperative Extension farm advisors, a small group of interested farmers and PCAs in 1991.
