“…The genetic material is another factor that could be influencing these low disease levels, since the Ponny Express F1 variety has been reported to be resistant to the wilt caused by Fusarium sp, (one of the main pathogens associated with tomato wilt). Montiel et al (2020) report the incidence of wilt by Fusarium sp. in nine commercial tomato genotypes, with the lowest incidence (0.03%) being reported for the Ponny Express F1 variety.…”

Objective: To characterize the agronomic and phytosanitary aspects of the tomato production units of the Comiteca-Tojolabal Plateau, Chiapas, Mexico.Design/Methodology/Approach: A random sampling of n=76 tomato fields was performed; agronomic practice surveys were applied to their respective farmers, and the phytosanitary status of each site was evaluated.Results: Tomatoes are grown in shade houses, in plots that mostly do not exceed 0.5 ha. The most common practices are crop rotation, one tomato cycle per year, incorporation of previous crop residues, and fertilization every 5-8 days. For phytosanitary management, foliar sprays are usually performed every 5-8 days. In order to prevent diseases and pests, 67% of producers pre-treat seedlings and 95% apply bactericides and fungicides to the roots during the first 45 days of the crop. The most important pests and diseases are whitefly, thrips, Bactericera sp., late blight, virosis, and wilt. The percentage of plants that suffer from root and vascular diseases ranges from 0-38%. However, low values were more frequent. The regional severity of wilting is low, since 90% of the plants evaluated did not present symptoms. Study Limitations/Implications: This is the first work to describe the agronomic and phytosanitary aspects of tomato cultivation in this region. Additional research with this approach is required and this work will be the basis for further studies.Findings/Conclusions: Most of the tomato farms have less than 0.5 ha and their farmers carry out intensive phytosanitary management with pesticides. In addition to chemical control, the cultural practices used may contribute to a low incidence and severity of soil-borne diseases. The most important crop diseases are late blight and virosis.

La marchitez o secadera del tomatillo es una enfermedad causada por hongos con origen en el suelo, entre los que destacan Fusarium oxysporum, Macrophomina phaseolina y Rhizoctonia solani, causando pérdidas por la carencia de variedades resistentes. El objetivo de este estudio fue determinar la respuesta del tomatillo (Physalis ixocarpa Brot.), híbridos Dalí, Siqueiros y Tamayo, así como los cv. Gabriela, Puebla, San Miguel y Tecozautla, hacia aislados patogénicos de F. oxysporum, M. phaseolina y R. solani. El estudio se realizó bajo condiciones de invernadero, en macetas se colocó arena de río + sustrato de turba (1:3 v/v) esterilizado y después se inoculó, con tres aislados de F. oxysporum 1.6x105 UFC, dos de M. paseolina y tres de R. solani (8 g de semilla de sorgo infestada/maceta, de cada hongo). En cada maceta se depositaron cinco semillas del cultivar de tomatillo correspondiente, luego se taparon con el mismo sustrato e incubaron por 30 días. Se utilizó un diseño completo al azar, con tres repeticiones (macetas). En el tratamiento testigo las semillas se sembraron sobre suelo sin hongo. A los nueve días después de la siembra (dds) se estimó la emergencia de plántulas, 30 dds, la severidad de la infección de por cada uno de los patógenos (escala de 0-5). Los datos se analizaron mediante estadística no paramétrica. Los siete cultivares probados fueron susceptibles a las especies F. oxysporum, M. phaseolina y R. solani, algunos de los aislados probados ejercieron un efecto significativo diferencial de virulencia, en algunas de las variedades estudiadas.
