Herbicidas coformulados sobre el control de malezas en el cultivo de maíz (Zea Mays).

This document deals with the importance of co-formulated herbicides on weed control in corn (Zea Mays) cultivation. The conclusions determined that weeds in corn cultivation represent a recurring challenge in most areas of arable land. Like crops, they have emerged as unintended results of human selection processes, in which certain species now prevail over crops and cause significant economic losses. Globally, it is estimated that there is a diversity of approximately eight thousand species of unwanted plants, and of all the damage caused by harmful organisms in agriculture, weeds contribute 13%. Herbicides eliminate weeds by altering biochemical processes, such as photosynthesis, that occur in the symplast or living system of the plant. Herbicides have the ability to disturb soil ecosystems through their direct and indirect influence on various elements of the soil microbiota, such as phytopathogenic organisms, antagonists, mycorrhizae and microbial communities. Herbicides can influence various physiological aspects of weed plants, such as growth control, suppression of cell division, reduction of respiratory and photosynthetic activity, as well as interference in complex metabolic processes. It is crucial to recognize problem weeds in corn cultivation, select appropriate herbicides and doses, use high quality water, apply adjuvants when necessary to improve effectiveness, calibrate spray equipment, ensure adequate contact with the weed at sufficient doses and facilitate penetration into the plant. Within the economic analysis of the cultivars, positive net benefits have been evident, particularly in the use of co-formulated herbicides. These benefits were notably influenced by weed control results, as weeds represent a major barrier to global agricultural production. Weeds are plants that, under certain conditions, cause economic and social damage to farmers.
