Mistletoes largely vary in the number of species that they can parasitize. In temperate rainforests southern Chile, we found two mistletoe species: Tristerix corymbosus, a generalist able to parasitize at least 30 plant species, and Desmaria mutabilis, which only parasitizes Nothofagus trees (that T. corymbosus is unable parasitize). Nevertheless, some parasitized by corymbosus. How this happen...

Abstract Background Yellow (stripe) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is an economic disease of wheat. Growth-promoting fungi (GPF) such as Trichoderma asperellum and Penicillium simplicissimum have been investigated for their potential to control yellow rust involvement in gene expression four PR proteins all-stage resistance. Results Wheat plants (cv. Sids-12) treated...

Sampling of agricultural soils from the Mexican northeastern region was performed to detect Trichoderma spp., genetically characterize it, and assess its potential use as a biologic control agent against Macrophomina phaseolina. M. phaseolina is a phytopathogen that attacks over 500 species of cultivated plants and causes heavy losses in the regional sorghum crop. Sampling was performed immedia...

Abstract The increasing demand for agricultural products can be met by maximizing production potential and reducing crop losses caused common plant-parasitic nematodes. Chemical-based nematode management is a successful technique mitigating damage yield pests; however, inappropriate irresponsible application of synthetic pesticides has negative impacts on fauna, bioflora, natural enemies such a...

background: combination of cyromazine as an insect growth regulator (igr) and nasonia vitripennis (hymenop tera: pteromalidae) a parasitic wasp may be an effective tool for reducing the house-fly populations in poultry houses and livestock farms. this study was conducted to assess the side effects of the igr cyromazine on the level of parasit ism and numbers and the longevity of emerged n. vitr...

blight, caused by mycosphaerella rabiei is the most important disease of chickpea in iran. in order to find a method for the biological control of the disease, the inhibitory effect of 36 isolates of three species, trichoderma harzianum, t. virens and t. atroviride, on a most virulent isolate of the pathogen, in hyperparasitism, dual culture, and production of volatile antibiotic compounds were...
