Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

In order to evaluate the effect of different Trichoderma isolates on reducing the effects of drought stress on Polianthes tuberose flower, two factorial experiments were carried out based on a completely randomized design with three replications. In the first and second experiments, the first factors were Bi and 65 isolates of Trichoderma harzianum at three levels (0,...

Towards assessing the biodiversity and biogeography of Trichoderma, we have analyzed the occurrence of Trichoderma species in soil and litter from four areas in China: North (Hebei province), South-East (Zhejiang province), West (Himalayan, Tibet) and South-West (Yunnan province). One hundred and thirty five isolates were grouped according to tentative morphological identification. A representa...

The diversity of Trichoderma spp. was investigated in alkaline soils of pistachio orchards at different geographic areas in Kerman province, Iran. A total of 161 Trichoderma isolates were obtained and identified at the species level by their morphological characters and sequence analysis of their internal transcribed spacer (ITS) and tef1-α genomic regions. Totally, five species of Trichoderma ...

Alternaria leaf spot disease is a major threat to sesame (Sesamum orientale L.) caused by Alternari asesami. Induced resistance is an alternative to systemic disease resistance response of plants. The present study aims to evaluate Trichoderma species efficacy as biocontrol via induction of resistance against A. sesami in sesame species. During in vitro bio control test, T. harzianum colonize a...

Tolerance of Trichoderma species collected from tea plantation to fungicides was evaluated in vitro using poisoned food method. Fungicides like Carbendazim 50 WP, Copperoxychloride 50 WP, Hexaconazole 5 EC, and Propiconazole 25 EC were used at two lower and two upper of recommended doses. The growth of T. harzianum was mostly inhibited by the Carbendazim 50 WP and Propiconazole 25 EC with the r...

Trichoderma spp. cause large crop losses of the cultivated shiitake mushroom, Lentinula edodes. We bred several shiitake strains that are resistant to Trichoderma spp. using di-mon mating to establish a useful method for controlling the greenmold disease. We examined the competitive ability of L. edodes against Trichoderma spp. using a dual culture system to select resistant strains. By screeni...
