BACKGROUND Exposure to the fungal allergen Alternaria alternata as well as ryegrass pollen has been implicated in severe asthma symptoms during thunderstorms. We have previously shown that Alternaria extract induces innate type 2 lung inflammation in mice. We hypothesized that the innate eosinophilic response to Alternaria extract may enhance lung inflammation induced by ryegrass. METHODS Mic...

laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. factors evaluated were lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 ds cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). the maximum germination in salinity stres...

Herbicide resistance in weeds is a global threat to sustaining food security. In India, herbicide-resistant Phalaris minor was the major problem wheat for more than two decades, but continuous use of metsulfuron-methyl (an ALS inhibitor) control broadleaf has resulted evolution inhibitor-resistant Rumex dentatus L. This review summarizes current scenario herbicide R. dentatus, along with its ec...

Remediation of soils contaminated with petroleum is a challenging task. Four different bioremediation strategies, including natural attenuation, biochar amendment, phytoremediation with ryegrass, and a combination of biochar and ryegrass, were investigated with greenhouse pot experiments over a 90-day period. The results showed that planting ryegrass in soil can significantly improve the remova...

Till now, herbicide seems to be a cost effective tool from an agronomic view point to control weeds. But long term efficacy and sustainability issues are the driving forces behind the reconsideration of herbicide dependent weed management strategy in rice. This demands reappearance of physical and cultural management options combined with judicious herbicide application in a more comprehensive ...

To investigate the effects of humic acid and mycorrhiza fungi on visual quality, some characteristics of roots and chlorophyll changes of ryegrass, an experiment was carried out in Research Greenhouses of Department of Horticultural Science, University of Tehran, in spring and summer of 2009. The ryegrass was “Speedy green” perennial ryegrass, which is composed of three lolium (Lolium perenne L...

Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grass species in Europe. In Portugal 34% of the cultivated area is dedicated to animal fodder. Italian ryegrass area in Entre Douro e Minho (EDM) region was mainly with landraces. Changes in traditional agricultural systems are contributing to a major loss of genetic diversity mainly to landraces. Portuguese Italian ...
