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 objective of this study was to compare FirstAct with several tank mix partners for efficacy in herbicide-tolerant grain sorghum. (quizalofop) alone or mixtures controlled Johnsongrass 94% more. However, mixing any broadleaf herbicide generally antagonistic Palmer amaranth control. Minor sorghum injury 5% less by four weeks after postemergence treatment. Sorghum yields increased all treatmen...

Italian ryegrass (Lolium multiflorum L.), a cross-pollinated grass, is gradually becoming predominant weed in wheat fields China and evolving resistance to many groups of herbicides. The aim this study determine the levels single L. population from field Henan Province China, three modes action (MoAs) herbicides further characterize potential mechanisms. This evolved multiple herbicide resistan...

two separate greenhouse experiments were conducted in the greenhouse of the iranian plant protection research institute, tehran, to compare the efficacy of some acetyl coa carboxylase (accase) and acetolactase synthase (als) inhibiting herbicides in control of wild oat biotypes. in each experiment, populations were independently treated by 10 herbicides each in 12 replications. to evaluate the ...

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 ...

The gene that encodes acetyl-coenzyme A carboxylase (ACCase; EC 6.4.1.2) in the eukaryotic alga Cyclotella cryptica has been isolated and cloned, representing the first time that a full-length gene for this enzyme has been isolated from a photosynthetic organism. The gene contains a 447-base pair intron that is located near the putative translation initiation codon and a 73-base pair intron tha...

The challenges of grass-weed control in a mild Atlantic climate, added to by the use non-inversion tillage and limited herbicide options necessitated on-farm knowledge acquisition on grass weeds Ireland. We surveyed 103 farms from 2020 2021 which, 62 were plough-based 41 tillage. survey comprised questionnaire determine grower demographics, challenges, adoption integrated methods (IWM); grid-sq...
