protein-rich hydrolysate from feather waste was obtained using a mixed culture of selected thermophilic actinomycete strains, and was tested for possible application as soil amendment and biological control agent. for this purpose, a 4 months laboratory experiment was carried out using two types of urban soils (sofia, bulgaria): native park soil and anthropogenic soil. the effect of the obtain...

An outline is given of some of the main factors and interactions involved in the development of ryegrass staggers viz: pasture structure, neurotoxin distribution within the pasture, and livestock feeding behaviour. Because neurotoxicity is mainly associated with ryegrass leaf sheath the aim of control measures is to minimise ingestion of this component when it is toxic. This can best be achieve...

Results are presented from a three gene population genetics and dynamics model of herbicide resistance in annual ryegrass. The models predictions are compared with those of other one and two gene resistance models to validate the modelling approach which will ultimately be used to develop a five-gene herbicide resistance model. The importance of initial gene frequencies for resistance in unsele...

abstract in order to determine efficacy of some registered graminicides in control of resistant and susceptible ryegrass biotypes, two greenhouse trials were conducted at weed research department of iranian plant protection research institute during 2007. experimental design was completely randomized design with eight replications. the susceptible and resistant biotypes were treated by 19 herbi...

In the present study, changes in microbial populations, enzyme activity and bacterial community structure contaminated soils were investigated during bioremediation of using Stenotrophomonas sp. strain DXZ9 ryegrass. The results showed that removal rates 81% for DDT 55% DDE (69% DDTs) with ryegrass-microbe. Microbial was remarkably improved, number bacteria increased sharply from 7.32 × 106 to ...

Water shortage is the primary limiting factor for crop production and long-term agricultural sustainability of the North China Plain. Forage cultivation emerged recently in this region. A fiver-year field experiment studies were conducted at Yucheng Integrated Experiment Station to quantify the water requirement and water use efficiency of seven forage varieties under climate variability, that ...

The crystal structure of the sobemovirus Ryegrass mottle virus (RGMoV) has been determined at 2.9 A resolution. The coat protein has a canonical jellyroll beta-sandwich fold. In comparison to other sobemoviruses the RGMoV coat protein is missing several residues in two of the loop regions. The first loop contributes to contacts between subunits around the quasi-threefold symmetry axis. The alte...

The prevalence of herbicide resistance in ryegrass (Lolium spp.) the wine-growing regions New Zealand is poorly understood. Cases glyphosate, glufosinate and amitrole-resistant were documented a few vineyards 2013, but there have been no regional surveys for resistance. To address this knowledge gap, 106 visited across important Marlborough Waipara late February 2021, Hawke’s Bay Gisborne 2022,...
