background and objectives: nowadays herbicide reduction and different approaches leading to this goal like split application have been brought to attention. at split application, recommended or reduced doses divided in such a way which half of dose applied at one growth stage and the other half will use at next growth stage and finally all used doses are equal to recommended or any other reduce...

Abstract Italian ryegrass [ Lolium perenne L. spp. multiflorum (Lam.) Husnot] is one of the most troublesome weeds worldwide. also a grass seed crop cultivated on 50,000 ha in Oregon, where both diploid and tetraploid cultivars are grown. For this work, we will refer to species as multiflorum, since common names annual same species. A survey was conducted understand distribution frequency its s...

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...

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...

Yellow nutsedge (Cyperus esculentus L.) and Johnsongrass (Sorghum halepense (L.) Pers.) are two of the most difficult weeds to control mostly due their asexual reproduction. reproduces through underground tubers rhizomes. In addition, is a problematic weed because its competitive nature C4 carbon fixation pathway metabolism. It typically grows 1.8 2.5 m tall can severely reduce yields in corn, ...

Abstract Ryegrass ( Lolium spp.) is a troublesome weed in major wheat Triticum aestivum L.) production regions the United States. High diversity and adaptive potential are known to contribute its success as species also create difficulties correct identification fields. The objective of this research was characterize for 16 different morphological traits among 56 populations collected from fiel...

various adjuvants carry out different functions depending on the herbicides types and the target species. outdoor pot experiments were conducted to evaluate the effects of three post-emergence herbicides, namely, clodinafop-propargyl, haloxyfop-p-methyl, and difenzoquat-methyl-sulfate, as influenced by two adjuvants, on wild oat (avena ludoviciana durieu.) control. the study was carried out at ...

The acetyl-CoA 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 five years and now are present in many populations across the Western Australian wheat belt (Owen et al. 2007...
