Descripción
Agriculture in the province of San Luis has had a growth today occupying about 10% of the production area. It spread and expanded direct seeding. Glyphosate was used as the main herbicide. The production model today uses almost no tillage, weed adapted and with a very strong dependence on chemical control, with few rotations. In recent years, weed populations are difficult to control begin to appear, is working on product research and identification of new recommended dose biotypes. At the micro level the cost of herbicides increases and an integrated management sought, but there is little information at a regional level and effects at the macro level in this work was suspended and conducted a survey that allows begin to measure the problem of weeds in agricultural production in the province of San Luis. Currently it estimated at a loss of 5% but is necessary to intensify work to show the current status, by area, the percentage occupation and advancing the impact of declining yields. You need to work with practices to suit each circumstance.
