EVALUATION OF HERBICIDES FOR WEED CONTROL IN VINEYARDS OF ENSENADA, BAJA CALIFORNIA

On the coast of Ensenada in Baja California (B.C.), the main wine region of Mexico is located.Due to its benign climatic conditions, fruits can be produced that allow the production of wines of the highest quality, and contribute 70% of Mexican wines.In vineyards, weeds, especially perennials such as grass (Cynodon dactylon L.), nutsedge (Cyperus esculentus L.) and bindweed (Convolvulus arvensis L.), constitute a major problem, which increases production costs.For its control, glyphosate is mainly used, a broad-spectrum systemic herbicide, to which harmful effects on human health and the environment are attributed.The objective of this work was to evaluate synthetic and natural herbicides as possible options for weed control in the vineyards of Baja California.The herbicides were tested: Glufosinate, Paraquat, Herbitec, Secbios, Secnatural and glyphosate plus a control without application.The treatments had a significant effect on weed control on the three sampling dates carried out.The results indicated that the herbicides tested were equally effective as glyphosate, and much superior to the absolute control.The effects of the treatments diminished as time went by.
