Wheat (Triticum aestivum) is a globally significant crop and staple food for millions of people. Weed infestation one the major constraints affecting wheat productivity worldwide. The purpose this study was to assess efficiency Carfentrazone ethyl 5% + Clodinafop propargyl 15% DF as post-emergence herbicide against predominant weeds in crops. constraint productivity. conducted using Randomized ...

Black-grass (Alopecurus myosuroides Huds.) is a common weed in Chinese wheat fields, and has become troublesome due to its evolution of herbicide resistance. One black-grass population (HN-14) collected from field where herbicides were applied was suspected be resistant (R) mesosulfuron-methyl. This study aims establish cross-resistance pattern explore potential resistance mechanisms. The resul...

Abstract Field and pot experiments were conducted in Greece to study the occurrence of resistance silky windgrass acetolactate synthase (ALS)- acetyl-CoA (ACCase)-inhibiting herbicides. Twenty-four populations examined whole-plant response experiments. High levels field-evolved chlorsulfuron (0% 28% control terms fresh weight reduction) with recommended field rates confirmed most populations. H...

Context Wild oats (Avena spp.), brome grass (Bromus spp.) and barley (Hordeum are significant weeds of crop production in south-eastern Australia. The presence herbicide resistance these weed species is a major limiting factor on both productivity profitability.Aims We aimed to determine the distribution across Australia.Methods Several surveys were conducted randomly selected fields four state...

The acetyl-coenzyme A carboxylase (ACCase)-inhibiting cyclohexanedione herbicide clethodim is used to control grass weeds infesting dicot crops. In Australia clethodim is widely used to control the weed Lolium rigidum. However, clethodim-resistant Lolium populations have appeared over the last 5 years and now are present in many populations across the western Australian wheat (Triticum aestivum...

The first enantioselective copper-catalyzed decarboxylative propargylic alkylation has been developed. Treatment of propargyl β-ketoesters with a catalyst, prepared in situ from [Cu(CH3 CN)4 BF4 ] and a newly developed chiral tridentate ketimine P,N,N-ligand under mild reaction conditions, generates β-ethynyl ketones in good yields and with high enantioselectivities without requiring the pregen...

in order to investigating theeffects of  crop rotation and applying of herbicides on weed distribution in  irrigated wheat fields of kermanshah province, this study was performed during  2011-2012. multivariate analysis (rda) revealed the significant relationship between composition and species frequency and exerted management techniques. the first and second features of rda indicated 57%, 74.9...

Chickpea (Cicer arietinum L.) commonly known as gram or Bengal belongs to the family Leguminaceae (Fabaceae). It's one of most important rabi season pulse crops grown in India for economic importance and improve soil fertility. The productivity chickpea is low despite having high-yielding varieties new agronomic practices. One causes poor infestation weeds field chickpea. It a competitor becaus...

A field experiment was conducted during the winter (rabi) season of 2021–22 at Indian Agricultural Research Institute, New Delhi, to investigate effect nano-urea and herbicides on yield yield-attributing characters wheat (Triticum aestivum L.). The tested in a split-plot design with 4-nano-urea based treatments, viz. control (no nitrogen), recommended dose nitrogen (RDN) 120 kg N/ha, 50% RDN + ...
