Abstract

Abstract Humid tropical regions of Costa Rica have ideal environmental conditions for vigorous weed growth. Vegetation management before and after planting requires more time and resources than any other activity in small‐scale maize (Zea mays L.) production. No‐tillage vegetation management systems tested were superior to traditional no‐tillage or mechanised systems. Insect damage to maize from Diabrotica balteata Leconte, Spodoptera frugiperda (J. E. Smith), Cyrtomenus bergi Froeschner and Phyllophaga spp. was significantly less with no‐tillage in contrast to ploughed systems.
