LOMELI VILLANUEVA, José Ramón  e  ALVAREZ GONZALEZ, Nazario. WEED CONTROL IN IRRIGATION DISTRICTS WITH LIGHT WEIGHT EQUIPMENT. Rev. Fac. Nac. Agron. Medellín [online]. 2010, vol.63, n.2, pp.5661-5667. ISSN 0304-2847.

In Mexico, the mechanical weed control was traditionally carried out with inadequate equipment which caused damage to the slopes and changes in the hydraulic section. In order to solve this problem, light weight equipment is currently being used to allow the development of a vegetation cover to retain soil with no interference with water flow, reducing erosion and maintaining stable conditions in the slopes. This paper addresses aspects related to characteristics and criteria for selecting and sequencing tools for use. The costs of weed control in irrigation channels, drains and roads have been reduced 39.21% compared to using inadequate equipment. The versatility of light weight equipment allows the use of the most appropriate implement for each weed. In Mexico, the current inventory includes 263 light weight devices with which a potential weed control of 90% can be obtained in chanels and 70% in drains of the Irrigation Districts.
