Resumen
Despite now being considered as a very innovative technique, the use offlaming for weed control is an old tradition. It was very common in the USA untilthe 1960s, when herbicides were still not very popular. After several decades,interest has been renewed in the USA, Canada and Europe, because of increasingenvironmental and health concerns. Flaming can be used to control weeds beforecrop planting/emergence (non-selective) and after crop emergence (selective).In this context, a specific machine for mechanical-thermal weed control in maize isbeing developed within the European Project RHEA. This machine will provideselective thermal in-row weed control and mechanical between-row weedremoval.This paper focuses on thermal weed control and reviews some of the studies thatdescribe the tolerance of maize to flaming. The yield loss is generally very low andthe treatment does not greatly affect the production, especially with doses lowerthan or equal to 50 kg ha-1. The maximum threshold is generally not higher than 15-20% of yield loss and is usually reached just with doses higher than 100 kg ha-
