Abstract

A key element of a project designed for integrated pest management in alfalfa fields in New York State is a comprehensive simulation model. The model was developed as a guide for growers to determine when the costs of control measures against alfalfa weevil would be worthwhile. The model incorporates crop and insect submodels. Optimization techniques were used to identify the more cost effective of the possible management strategies. The project has been an unqualified success from a research standpoint but the results are not widely implemented by growers. In this respect, the project has suffered from institutional problems at the research level, lack of confidence and commitment in extension, and skepticism among growers. To rectify this situation, project staff recently adopted new approaches for implementing the program.

Résumé

L'un des éléments clés d'un projet élaboré pour la lutte intégrée dans les champs de luzerne de l'état de New York est un modèle de simulation globale. Le modèle a été élaboré pour guider les producteurs voulant préciser dans quelles conditions les coûts des mesures de contrôle contre le charançon postiche de la luzerne demeurent inférieurs aux pertes de rendement dues aux attaques du charançon. Le modèle incorpore les sous-modèles culture et charançon. Des techniques d'optimisation ont été utilisées pour préciser l'éventail des stratégies possibles de régie, de sorte que le modèle puisse être utilisé à coût raisonnable. Le projet s'est avéré un plein succès du point de vue recherche, mais les résultats ne sont par largement appliqués par les producteurs. A ce sujet, le projet a souffert de problèmes institutionnels du point de vue recherche, d'un manque de confiance et d'implication du point de vue extension, et du scepticisme des producteurs. Afin de corriger ces défauts, le personnel du projet a récemment mis en place de nouvelles approches d'implantation du programme.
