Efectos de los fungicidas en el control del moho gris Botrytis cinérea en el cultivo de tomate (Solanum lycopersicum)

The tomato, unknown in the Old World until the 16th century and still little consumed in the 19th century, has become the great vegetable of the 20th century, both in commercial cultivation and in home gardens. It is appreciated for its freshness and is the base or garnish for all kinds of dishes, both raw and cooked. Under the denomination of gray rot, a group of diseases of various crops with a common symptomatology is included, characterized by the presence on different plant organs of a powdery grayish mold. These diseases are produced by different species of the genus Botrytis. From the very beginning of agriculture, associated with the beginning of the sedentary life of humans, crops suffered from the attack of plagues that decimated them and drastically reduced the production and storage of food. From the invention of writing and throughout the centuries numerous texts have referred to attacks by insects, fungi, rodents and other agents. For its control, fungicides belonging to the benzimidazoles, dicarboximides, strobilurins, pyrimidineamides groups, among others, are used. Due to the resistance mechanisms of the pathogen, it is necessary for disease management strategies to permanently evolve towards new control alternatives. Among the products used to control gray mold in greenhouse and open field tomato crops, the following stand out: Chlorothalonil, Methyl thiophanate, Pyrimethanil, Thiabendazole.
