Glyphosate-resistance evolution in weeds is evident globally, especially in areas where transgenic glyphosate-resistant crops dominate. Resistance to glyphosate is currently known in 16 weed species, including rigid ryegrass in Australia. Following the first report of glyphosate resistance in 1998, there are now 78 documented glyphosate-resistant populations of rigid ryegrass in grain-growing r...

Quizalofop-p-ethyl (QPE) is a post-emergence herbicide that effectively controls grass weeds and is often detected in the environment. However, the biochemical and molecular mechanisms of QPE degradation in the environment remains unclear. In this study, a highly effective QPE-degrading bacterial strain J-2 was isolated from acclimated activated sludge and identified as a Pseudomonas sp., conta...

to study the molecular basis for resistance of lolium rigidum populations (from fars province) to aryloxyphenoxy propionate herbicide through dcaps method, an experiment was conducted at the biotechnology laboratory of shiraz university. eighteen populations of l. rigium suspected of herbicide resistance, from zarghan, fasa. noorabad and firoozabad areas which had survived a recomended dose of ...

Three perennial ryegrass (Lolium perenne) populations (R1, R2, and R3) with suspected resistance (R) to acetolactate synthase (ALS) or acetyl-CoA carboxylase (ACCase) herbicides were collected from wheat (Triticum aestivum) fields in northwestern Greece study the underlying mechanisms of their impact on growth rate competitive ability against wheat. Preemergence postemergence plant dose–respons...

Herbicides are the major tool for controlling large populations of yield depleting weeds. However, over-reliance on herbicides has resulted in weed adaptation and herbicide resistance. In recent years, early flowering species related to resistance is emerging, which may cause seed loss before crop harvest, creating a new problem non-chemical management. this study, homologue gene AGAMOUS sub-fa...

The present study was carried out at the Chaudhary Charan Singh Haryana Agricultural University, Hisar during winter (rabi) season of 2015–16 and 2016–17, to investigate influence fertilizer levels different treatments wild oat (Avena ludoviciana Durieu.) management on growth yield wheat (Triticum aestivum L.). There were 24 3 replications with (Levels-03) (management -08) as main subplot in sp...
