Efecto in vitro de plaguicidas comerciales sobre Trichoderma harzianum cepa A- 34
The work aims to evaluate the in vitro effect of six commercial pesticides on the mycelia growth, the spore production and conidia germination of Trichoderma harzianum strain A-34. The assay was carried out with the following products: folpet (Folpam 80 PH), zineb (Zineb 80 PH), mancozeb (Mancozeb 7...

Muiño, Berta Lina Hernández Pérez, Ricardo Guillen Sánchez, Dagoberto biocontrol fungicidas insecticida manejo integrado antagonista biocontrol fungicides insecticides integrated management antagonist The work aims to evaluate the in vitro effect of six commercial pesticides on the mycelia growth, the spore production and conidia germination of Trichoderma harzianum strain A-34. The assay was carried out with the following products: folpet (Folpam 80 PH), zineb (Zineb 80 PH), mancozeb (Mancozeb 75 PH), cipermetrina (Cipermetrina 10 EC), lambda cialotrina (Karate 5 EC) and abamectina (Abamectin 1.8 EC) to the concentrations of 10, 100, 200, 500, 1000 and 2000 mg L-1. The growth inhibition of the fungus colony, the effect of the pesticides on the spore production and the conidia germination were evaluated. The pesticides were classified according to their toxicity on the antagonist by the OILB scale and their compatibility according to the T value. The folpet, mancozeb and zineb fungicides, and the abamectina insecticide have inhibitory effect on the growth of the mycelia of the fungus T. harzianum, and they are classified as lightly toxic. However, when considering the T value, zineb is classified as very toxic, and mancozeb and folpet as moderately toxic, while the insecticides are not toxic to the antagonist. Fungicides affect the germination of the antagonist's conidia but insecticides do not. El trabajo tuvo como objetivo evaluar el efecto in vitro de seis plaguicidas comerciales sobre el crecimiento micelial, la esporulación y la germinación de los conidios de Trichoderma harzianum cepa A-34. El ensayo fue llevado a cabo con los siguientes productos: folpet (Folpam 80 PH), mancozeb (Mancozeb 75 PH) y zineb (Zineb 80 PH), así como de tres insecticidas: cipermetrina (Cipermetrina 10 EC), lambda cialotrina (Karate 5 EC) y abamectina (Abamectina 1,8 EC) a las concentraciones de 10, 100, 200, 500, 1000 y 2000 mg L-1. Fue evaluada la inhibición del crecimiento micelial de la colonia del hongo y la acción sobre la producción y la germinación de los conidios. Los plaguicidas fueron clasificados por su toxicidad sobre el antagonista de acuerdo con la escala de la OILB y por su compatibilidad según el valor T. Los tres fungicidas folpet, mancozeb y zineb tienen efecto inhibitorio sobre el crecimiento del micelio del hongo T. harzianum al igual que abamectina y son clasificados como ligeramente tóxicos. Sin embargo al considerar el valor T se clasifica a zineb, como muy tóxico, y a mancozeb y folpet como moderadamente tóxicos, mientras que los insecticidas resultaron no tóxicos. Los fungicidas afectan la germinación de los conidios del antagonista pero los insecticidas no.
