description Damping off  is caused by Pythium sp. in seedlings, which is the main cause of losses in chrysanthemum crops. This research aimed to evaluate the optimal dose of biocontrollers and chemical fungicides for Pythium sp. The application of the treatments was carried out both in a laboratory and on a greenhouse crop. A completely randomized design was used with 10 treatments (control, metalaxyl and chlorothalonil, azoxystrobin, Trichoderma harzianum, and Bacillus subtilis), applied at two doses: 100% and 150% of the commercial application. The results obtained in the laboratory phase showed that the inoculated control had the highest mycelial growth of Pythium sp., 36.43 cm in diameter. The treatments with chemical fungicides presented 100% control since there was no growth of Pythium sp. In the greenhouse, the chrysanthemum cultivation had the best results when T. harzianum was applied at a dose of 150% since only 9.33% incidence was observed. In terms of severity, the most effective treatment was the commercial dose of T. harzianum, with 4.9%. The best performance of the agronomic characteristics in the chrysanthemum plants was seen with the application of T. harzianum at a dose of 150% because the plants presented  higher plant height, fresh radicular mass, dry root mass, fresh aerial mass, mass dry air, number of buttons, floral diameter and floral mass.

La aplicación de los tratamientos se llevó a cabo tanto en laboratorio como en el cultivo bajo invernadero. Se empleó un diseño completamente al azar con 10 tratamientos (testigo, metalaxil y clorotalonil, azoxystrobin, Trichoderma harzianum, Bacillus subtilis, aplicados en dos dosis 100% de la aplicación comercial y 150%). Los resultados obtenidos en la fase de laboratorio mostraron que el testigo inoculado con oosporas tuvo el mayor crecimiento micelial de Pythium sp., 36,43 cm en diámetro, así mismo los tratamientos con fungicidas químicos presentaron un control del 100% ya que no hubo crecimiento de Pythium sp. En el invernadero, las plantas de crisantemo mostraron los mejores resultados cuando se aplicó T. harzianum en dosis de 150%, ya que se presentó tan solo un 9,33% de incidencia, mientras que referente a la severidad, el tratamiento más eficaz fue con T. harzianum en dosis comercial con 4,9%. El mejor comportamiento de las características agronómicas de las plantas de crisantemo se presentó con la aplicación de T. harzianum con dosis de 150%, ya que las plantas mostraron mayor altura, masa radicular fresca y seca, masa aérea fresca y seca, número de botones, diámetro floral y masa floral.application/pdfspaspaSociedad Colombiana de Ciencias Hortícolas-SCCH and Universidad Pedagógica y Tecnológica de Colombia-UPTChttps://revistas.uptc.edu.co/index.php/ciencias_horticolas/article/view/7955/8554Copyright (c) 2018 Revista Colombiana de Ciencias Hortícolashttps://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf37http://purl.org/coar/access_right/c_abf2Revista Colombiana de Ciencias Hortícolas; Vol. 12 No. 3 (2018); 646-657Revista Colombiana de Ciencias Hortícolas; Vol. 12 Núm. 3 (2018); 646-657Revista Colombiana de Ciencias Hortícolas; Vol. 12 No 3 (2018); 646-657Revista Colombiana de Ciencias Hortícolas; V. 12 N. 3 (2018); 646-657Revista Colombiana de Ciencias Hortícolas; v. 12 n. 3 (2018); 646-6572422-37192011-2173Trichoderma harzianumBacillus subtilisRoot rotFungicidesFlower qualityOrthogonal contrastsCrop protectionDiseasesTrichoderma harzianumBacillus subtilisPudrición radicularFungicidasCalidad de florContrastes ortogonalesProtección de cultivosEnfermedadesEfficacy of biocontrollers and fungicides for the control of Pythium sp. in chrysanthemum (Dendranthema grandiflora (Ramat.)
