Selectivity of Some Herbicides to Standard Wheatgrass (Agropyron desertorum (Fisch.) Schultes) During Stand Establishment and Seed Production
A study was conducted in the experimental field of the Institute of Forage Crops –
Pleven on a slightly leached chernozem soil in 2011-2012 to determine the selectivity of
some herbicides to standard wheatgrass (Agropyron ...
The Use of Vegetative Compatibility Tests for Identification of Biodiversity of Phytopathogenic Fungi
Visual assessment of phenotypes, performed when two strains of one fungal species
are cultivated in a mixed culture on specific media, is known as vegetative or heterokaryotic
compatibility or incompatibility test, which ...
Efficiencies of Different Methods for Determination of Organophosphate Pesticide Residues in Fermented Wheat Substrate
In the present work, the efficiencies of three different sample preparation methods for GC/
MS determination of pirimiphos-methyl and chlorpyrifos-methyl residues in wheat (Triticum
spelta) samples fermented by Lactobacillus ...
Impact of Trichoderma spp. on Soybean Seed Germination and Potential Antagonistic Effect on Sclerotinia sclerotiorum
Trichoderma species have been registered as species with important plant growth promoting
potential and antagonistic effect against various phytopathogens. Trichoderma isolates
