In vitro biocontrol activity of Trichoderma harzianum on Alternaria alternata in the presence of growth regulators
Trichoderma harzianum 650 (Th650) and Paenebacillus lentimorbus 629 (Pl629) selected earlier for their ability to control Rhizoctonia solani, Fusarium solani and F. oxysporum in vitro, were applied alone or combined with solarization (summer assay) and/or with methyl bromide (MeBr) (summer and w...

Biocontrol of root and crown rot in tomatoes under greenhouse conditions using Trichoderma harzianum and Paenibacillus lentimorbus. Additional effect of solarization
The obtainment of 30 new strains from native Trichoderma harzianum after UV light irradiation (UV-A and UV-C), and of 82 strains resulted from protoplast fusion were accomplished. The new strains, initially selected for their growing rate under low temperature and high pH conditions, as well as f...

New strains obtained after UV treatment and protoplast fusion of native Trichoderma harzianum: their biocontrol activity on Pyrenochaeta lycopersici
Bacteria from the rhizoplane and surrounding soil of healthy and Rhizoctonia
solani diseased tomato plants, cropped in greenhouse of the V Region of Chile,
were collected. The best bacterial strains, based on their ability to control
development of three R. solani isolates (identified as belongin...
