the present study evaluated the effects of different dosages herbicides oxyfluorfen and trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. in this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

Weeds pose a serious threat to wheat productivity. A study was undertaken during the winter season of 2019/20 in experimental field, National Agronomy Research Centre, NARC, Khumaltar assess various doses and application dates for controlling mixed weed flora wheat. The experiment laid out Randomized Complete Block Design with ten treatments replicated thrice net plot size 6 sq. m. included met...

Herbicide mixtures are a modern weed management practice as they reduce herbicide application. This study aimes to evaluate the effect of metribuzin, halosulfuron and flumioxazin applied individually (metribuzin:halosulfuron metribuzin:flumioxazin) on Chenopodium album, Amaranthus retroflexus, potatoes biomass chlorophyll-a fluorescence in 21 experiments. The individual experimental design was ...

ABSTRACT The sesame crop has great economic potential due to the various possibilities of exploitation, however, there is a lack information about chemical control weeds in crop, mainly application herbicides pre-emergence. Therefore, objective this study was evaluate viability and efficacy applied pre-emergence for crop. experimental design randomized blocks, with four replications. treatments...

Pyrolysis temperature and application rate of biochar to soil can influence herbicide behavior fertility. The objective was investigate the effect amendments with rates sugarcane straw biochar, produced at different pyrolysis temperatures, on sorption–desorption metribuzin in soil. analysis performed using high-performance liquid chromatography (HPLC). treatments were three temperatures (BC350,...

Abstract The objectives of this study were to determine if the level and consistency glyphosate-resistant (GR) horseweed control prior soybean planting can be improved by (i) adding halauxifen-methyl, 2,4-D ester, saflufenacil, metribuzin, or dicamba glufosinate, (ii) increasing rate glufosinate from 500 1,000 g ai ha –1 , (iii) 28% urea ammonium nitrate (UAN) as carrier solution. During a 2-yr...

Herbicide resistance in annual ryegrass across southern Australia is currently a major issue for grain producers. Currently annual ryegrass (Lolium rigidum Gaudin) has evolved resistance to all post-emergent herbicides that can be used to control it in cereal crops and to the pre-emergent herbicide trifluralin. No new herbicide modes of action for the control of annual ryegrass have been market...

A system suitable for the detection of meiotic aneuploidy is described in which various different origins of the aneuploidy can be distinguished. Aneuploid meiotic products are detected as black disomic spores held in asci containing all the products of a single meiosis. Aneuploidy may result from nondisjunction or from a meiosis in which an extra replica of one of the chromosomes has been gene...

in order to investigate the effects of composted manure and zeolite on efficacy of trifluralin in control of weed natural population in sunflower under different irrigation regimes, an experiment conducted in 2009 in tarbiat modares university, tehran, iran. a randomized complete block design in factorial arrangement with three replications was used. first factor was irrigation regimes that inv...
