The most common biological control agents (BCAs) of the genus Trichoderma have been reported to be strains of Trichoderma virens, T. harzianum, and T. viride. Since Trichoderma BCAs use different mechanisms of biocontrol, it is very important to explore the synergistic effects expressed by different genotypes for their practical use in agriculture. Characterization of 16 biocontrol strains, pre...

The aim of the present study was to examine the abilities of twenty-four isolates belonging to ten different Trichoderma species (i.e., Trichoderma atroviride, Trichoderma citrinoviride, Trichoderma cremeum, Trichoderma hamatum, Trichoderma harzianum, Trichoderma koningiopsis, Trichoderma longibrachiatum, Trichoderma longipile, Trichoderma viride and Trichoderma viridescens) to inhibit the myce...

Trichoderma sp., a well known biological control agent against several phytopathogens, was tested for its phosphate (P) solubilizing potential. Fourteen strains of Trichoderma sp. were isolated from the forest tree rhizospheres of pinus, deodar, bamboo, guava and oak on Trichoderma selective medium. The isolates were tested for their in-vitro P-solubilizing potential using National Botanical Re...

The purpose of this study was to evaluate the predatory activity of the nematode Butlerius spp. and fungal isolates of Duddingtonia flagrans, Clonostachys rosea, Arthrobotrys musiformis and Trichoderma esau against H. contortus infective larvae (L3) in grass pots. Forty-eight plastic gardening pots containing 140 g of sterile soil were used. Panicum spp. grass seeds (200 mg) were sown into each...

Introducción. Trichoderma spp. posee varios mecanismos para ayudar con la promoción del crecimiento de las plantas: síntesis fitohormonas, producción vitaminas, solubilización nutrientes, aumento captación y translocación mayor desarrollo raíz aumentos en tasa metabólica. Objetivo. Evaluar plantas tomate inoculadas cepas nativas e importadas tanto a nivel invernadero como campo. Materiales méto...

In vitro studies with Trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. Microscopic observations showed that T. harzianm and T. viride, isolated from soil samples from Ahwaz and Karaj, adversely affected the myce...

La berenjena es una solanacea afectada por la Marchitez Vascular (MV) asociada a Fusarium oxysporum f. sp. melongena que destruye el tejido vascular, causando clorosis y finalmente muerte de planta, generando pérdidas entre 70 90 % producción en cultivos establecidos del departamento Córdoba, Colombia. El objetivo fue identificar cepas nativas Trichoderma spp. para biocontrol spp., berenjena. F...
