This work highlights the ability of various cyanobacterial extracts from Anabaena spp., Tolypothrix Nostoc or Trichormus, among others genera, to control incidence damping-off caused by Pythium ultimum in cucumber seedlings. Protocols applied aimed at preliminary characterization collection were very useful for predicting their phytotoxic, phytostimulating and biopesticidal capacity. First, phy...

Lumsden, R. D., and Locke, J. C. 1989. Biological control of damping-off caused by Pythium ultimum and Rhizoctonia solani with Gliocladium virens in soilless mix. Phytopathology 79:361-366. Gliocladium virens controlled damping-off of zinnia, cotton, and Disease control efficacy lasted for at least 2 mo when G. virens was cabbage caused by Pythium ultimum or Rhizoctonia solani in nonsterile int...

Finding new sustainable tools for crop protection in horticulture has become mandatory. Giant reed (Arundo donax L.) is a tall, perennial, widely diffuse lignocellulosic grass, mainly proposed bioenergy production due to the fact of its high biomass yield and low agronomic requirements. Some studies have already highlighted antimicrobial antifungal properties giant reed-derived compounds. This ...

identification and transfer of desirable genes from wild relatives to crop species is one of the breeding solutions for producing resistance to pathogens and pests. this study was conducted to evaluate crossability and the response to pythium ultimum in three species of the genus carthamus. to assess response to the pathogen, eight safflower (carthamus tinctorius l) genotypes, two ecotypes of c...
