TL;DR: The molecular phylogeny supports recognition of a new genus, Schoenefeldiella, and a new combination, Sch Koenfeldiella transiens, and generic emendations for Coelachyrum, which now includes five species including a new pair proposed here, Coelachesyrum burttii, and Eleusine, who now includes 11 species.
Abstract: To investigate the evolutionary relationships among species of Afrotrichloris, Apochiton, Coelachyrum, Dinebra, Eleusine, Leptochloa, and Schoenefeldia of subtribe Eleusininae, a phylogeny based on DNA sequences from nine gene regions (ITS, rps16‐trnK, rps3, rps16, rpoC2, rpl32‐trnL, ndhF, ndhA, ccsA) is presented. Previous molecular phylogenies indicated that Coelachyrum was polyphyletic and Schoenefeldia was paraphyletic, with Afrotrichloris embedded within it. Apochiton burttii was embedded in the Coelachyrum clade paired with C. longiglume, Coelachyrum poiflorum was placed outside of Coelachyrum and sister to Eleusine, and Schoenefeldia is paraphyletic, with its two species forming a grade sister to Afrotrichoris. Our molecular phylogeny supports recognition of a new genus, Schoenefeldiella, and a new combination, Schoenfeldiella transiens. In addition, we provide generic emendations for Coelachyrum, which now includes five species including a new combination proposed here, Coelachyrum burttii, and Eleusine, which now includes 11 species.
TL;DR: Several nomenclatural modifications based on a recent molecular study of Leptochloa are provided, including a generic transfer and four new varietal combinations for Dinebra Jacq and two corrections are made for the specific epithets of Disakisperma.
Abstract: This paper provides several nomenclatural modifications based on a recent molecular study of Leptochloa. One generic transfer and four new varietal combinations are proposed for Dinebra Jacq. One orthographic correction and three new varietal combinations are provided in Diplachne P. Beauv. Two corrections are made for the specific epithets of Disakisperma. One orthographic correction is provided for Leptochloa.
TL;DR: The dominant weeds in wheat crop consisted of Chenopodium album.., Anagallis arvensis L., Argemone mexicana L., Solanumnigrum L., Sonchus spp. as mentioned in this paper.
Abstract: The dominant weeds in wheat crop consisted of Chenopodium album.., Anagallis arvensis L., Argemone mexicana L., Solanumnigrum L., Sonchus spp. Almost similar weeds were recorded in both crops which comprised of Cyperus rotundus L., Cynodon dactylon (L.) Pers, and Dinebra arabica Jacq.
TL;DR: Results revealed that the highest infestation of Dinebra arevica, Echinochloa crusigally were recorded in Soyabean, Jowar and Pigeonpea crops of Mandsour district.
Abstract: A Survey of weed flora in Kharif crops viz Soyabean, Jowar and Pigeonpea etc. of Mandsour and Ratlam District of M.P. was conducted in the year 2005. Results revealed that the highest infestation of Dinebra arevica, Echinochloa crusigally were recorded in Soyabean, Jowar and Pigeonpea crops of Mandsour district. Disteria spp. was observed at IInd rank in respect of weed density. While in Ratlam district the highest infestation of Echinochloa crusigally was recorded is Soyabean, Jowar and Pigeanpea crops. Dinebra arevica, was observed in IInd rank with respect of weed density.
