Principales fungicidas químicos para el control del hongo Fusarium verticillioides, que afectan en el cultivo de maíz (Zea mays L.)”

This document was developed with the purpose of searching for the main chemical fungicides for the control of the fungus Fusarium verticillioides, which affect corn cultivation. Among the conclusions, it was determined that Fusarium verticillioides is one of the main pathogens within the complex of fungi that attack corn cultivation, both globally and nationally, penetrating through the plant, especially through roots, stems and cob, producing a certain class of toxins that affect plant tissue and grains, reducing yields and production quality; chemical products, mainly fungicides, allow the control of F. verticillioides, which, using it in mixtures and in adequate doses, allows to reduce production costs and, in turn, does not cause environmental deterioration due to its indiscriminate use; The main chemical fungicides for F. verticillioides in corn crops are Captan, Quintozeno, Fludioxonil + Metalaxil-M, Difenoconazole, Carboxin + Thiram, considered the most used products for the control of this pathogen and the best chemical product that controls F. verticillioides in corn cultivation is the mixture of Fludioxonil + Metalaxil-M, which in our country is marketed as a commercial product that contains the two active ingredients Fludioxonil, which belongs to the chemical group of phenylpyrroles, a molecule active against a wide spectrum of higher fungi, Ascomycetes, Basidiomycetes and Deutoromycetes present in the seed and in the soil and Metalaxyl-M, which belongs to the chemical group of Phenylamines, a molecule active against fungi of the Oomycetes class.

El presente documento se desarrolló con la finalidad de buscar los principales fungicidas químicos para el control del hongo Fusarium verticillioides, que afectan en el cultivo de maíz. Dentro de las conclusiones se determinó que Fusarium verticillioides es uno de los principales patógenos dentro del complejo de hongos que atacan al cultivo de maíz, tanto a nivel mundial como nacional, penetrando por la planta, especialmente por raíces, tallos y mazorca, produciendo cierta clase de toxinas que afectan al tejido del vegetal y los granos, disminuyendo los rendimientos y la calidad de la producción; los productos químicos, principalmente los fungicidas, permiten el control de F. verticillioides, lo que utilizándolo en mezclas y en dosis adecuadas permiten disminuir los costos de producción y a su vez no causan deterioro ambiental por su uso indiscriminado; los principales fungicidas químicos para F. verticillioides en el cultivo de maíz son Captan, Quintozeno, Fludioxonil + Metalaxil-M, Difenoconazole, Carboxin + Thiram, considerados como los productos más utilizados para el control de este patógeno y el mejor producto químicos que controla F. verticillioides en el cultivo de maíz es la mezcla de Fludioxonil + Metalaxil-M, que en nuestro medio país se comercializa como un producto comercial que contiene los dos ingredientes activos Fludioxonil, que pertenece al grupo químico de los fenilpirroles, molécula activa contra un amplio espectro de hongos superiores, Ascomycetos, Basidiomycetos y Deutoromycetos presentes en la semilla y en el suelo y Metalaxyl-M, que pertenece al grupo químico de las Fenilaminas, molécula activa contra hongos de la clase Oomycetos.
