Studies were undertaken to determine the comparative efficacy of native biocontrol agents viz., Pseudomonas fluorescens isolate PS-4, Trichoderma harzianum isolate TH-H-3 and T. virens isolate TV-K-3 @ 5X10 cfu/g talc; organic amendments viz., neem seed powder @ 250 mg/kg soil and farmyard manure @ 8 1500 mg/kg soil; carbofuran @ 33.4 mg/kg soil, topsin-M @ 1.4 mg/kg soil and bavistin @ 2.0 mg/...

Dieback disease caused by L. theobromae has destroyed nutmeg plantations in Aceh Selatan. Until now, effective control not been found, while farmer continue to use pesticides that have a negative impact on the environment. Therefore, biological is an alternative environmentally friendly being promoted. The purpose of this researth was dieback inducing resistance using three spesies Trichoderma ...

background and objectives: different trichoderma species play role as suitable alternative for chemical fertilizers and successful biological tool in stable agriculture. these microorganisms show rivalry in food and place sources. they establish in the rhizosphere of most agricultural and non-agricultural plants via producing spores. they also could induce resistance in plants. these properties...

soybean, glycine max (l.) merr is one of the most important oilseed plants in the world and phythophthora root and crown rot is a significant limiting factor for its planting. in the present study the antagonistic effect of 12 trichoderma spp. in vitro and these trichoderma spp. in combination with bradyrhizobium japonicum in vivo on phytophthora sojae and soybean growth were tested. in laborat...

in the present study, the diversity of trichoderma spp. was investigated in alkaline pistachio soils at different geographic area in kerman province, iran. a total of 161 trichoderma isolates were obtained and identified at the species level by analysis of their morphological characters and sequence analysis of their internal transcribed spacer regions of the rrna cluster and tef1 genes as phyl...

Objective: The genus Trichoderma comprises a great number of fungal strains that act as biological control agents, the antagonistic properties of which are based on the activation of multiple mechanisms. Methods: Trichoderma strains exert biocontrol against fungal phytopathogens either indirectly, by competing for nutrients and space, modifying the environmental conditions, or promotin...
