Heterologous expression of CYP81A6 from rice (Oryza sativa) in Escherichia coli and structural analyses of bensulfuron-methyl metabolites Weed Biol. Manag. (IF 1.4) Pub Date : 2021-08-16 Takuya Yamaguchi, Kohei Matsumura, Satoshi Iwakami, Yukari Sunohara, Hiroshi Matsumoto
Herbicides are often selective and kill only weeds without affecting crops. In rice, CYP81A6 is responsible for tolerance toward acetolactate synthase herbicides such as bensulfuron-methyl (BSM). CYP81A6 is thought to metabolize BSM into a nontoxic metabolite, that is, O-demethylated BSM. However, direct evidences for this reaction have not been reported, likely due to difficulties in the heterologous

Fresh root fragments of Rumex crispus and Rumex obtusifolius , which initially contain 65–70% moisture, progressively lose moisture when desiccated under conditions matching summer weather in southeast England. The likelihood of shoot emergence and the time it took in glasshouse conditions were both affected by desiccation, with R. crispus the most affected up to 48 hr and R. obtusifolius slower to

Maize-soybean intercropping effect on yield productivity, weed control and diversity in northern Ghana Weed Biol. Manag. (IF 1.4) Pub Date : 2020-06-01 Albert Berdjour, Ibrahim Yakamba Dugje, Israel Kwame Dzomeku, Nurudeen Abdul Rahman
The cereal–legume cropping system is a common practice across the tropical world. However, there are limited quantitative data on the effect of cereal–legume intercropping on weed species diversity. A study was conducted in the Guinea savanna zone of Ghana to evaluate the effect of maize–soybean intercropping on yield productivity and weed species control. The treatments used include three maize maturity

A tetraploid Echinochloa with plagiotropic tillers: Its distribution and habitat in the northern part of the main island of Japan Weed Biol. Manag. (IF 1.4) Pub Date : 2020-06-01 Kentaro Yasuda, Kaoru Mori, Yuichiro Nakayama
An annual Echinochloa with plagiotropic tillers (semi‐erect type) was found on a paddy levee in Miyagi prefecture in Japan. This semi‐erect type had tetraploid chromosome numbers (2n = 36) and would be expected to be E. oryzicola. However, its appearance was distinct from that of E. oryzicola. To collect seed samples and clarify its distribution and habitat, exploration and collection surveys were

Enhanced weed‐crop competition effects on growth and seed production of herbicide‐resistant and herbicide‐susceptible annual sowthistle ( Sonchus oleraceus ) Weed Biol. Manag. (IF 1.4) Pub Date : 2020-05-12 Ahmadreza Mobli, Sahil, Rajpaul Yadav, Bhagirath S. Chauhan
Enhanced crop competition could aid in the management of annual sowthistle (Sonchus oleraceus L.), a dominant weed of Australian cropping systems. A two-year pot study was conducted to evaluate the effect of wheat (Triticum aestivum L.) planting densities (0, 82, and 164 wheat plants/m) on growth and seed production of glyphosate-resistant (GR) and glyphosate-susceptible (GS) biotypes of annual sowthistle

Weedy rice: An expanding problem in direct‐seeded rice in the Philippines Weed Biol. Manag. (IF 1.4) Pub Date : 2020-04-01 Leylani M. Juliano, Dindo King M. Donayre, Edwin C. Martin, Jesusa C. Beltran
Weedy rice is morphologically similar to cultivated rice (Oryza sativa L.). It has biological characteristics that identify it as a weed. Its important weedy characteristics, that is, early and heavy seed shattering, makes it very difficult to control. Weedy rice has not been reported to be an important weed problem in transplanted, flooded rice. However, the shift to direct‐seeded rice (DSR) due to

The influence of the soil management systems on aboveground and seed bank weed communities in olive orchards Weed Biol. Manag. (IF 1.4) Pub Date : 2020-03-22 Antonio J. Carpio, Ángel Lora, Enriqueta Martín‐Consuegra, Rafael Sánchez‐Cuesta, Francisco S. Tortosa, Jesús Castro
The biodiversity of farmed landscapes is, in the context of agricultural intensification, a key aspect with regard to improving the sustainability of agroecosystems. Olive groves are undergoing rapid changes because of the spread of intensive farming systems, which may have negative environmental impacts. This paper reports a survey on the aboveground flora and seed banks in five olive groves located

Isolation and identification of two phytotoxic compounds from the medicinal plant Cassia alata L. Weed Biol. Manag. (IF 1.4) Pub Date : 2020-01-26 Krishna Rany Das, Keitaro Iwasaki, Kiyotake Suenaga, Hisashi Kato‐Noguchi
Cassia alata (Caesalpiniaceae), an ornamental shrub, has many biological properties such as antifungal and antibacterial activities. Several bioactive and phytotoxic compounds have already been isolated from C. alata. Phytotoxic substances from plants have drawn attention as an alternative biological approach to control weeds. Thus, we conducted this research to explore other phytotoxic compounds in

A comprehensive study on occurrence records of African neglected and underutilized weed species, Cleome gynandra L. (cat's whiskers) validating the ecogeographical range expansion in West Bengal, India Weed Biol. Manag. (IF 1.4) Pub Date : 2019-12-26 Ekta Bhattacharya, Rahul Bose, Suparna Mandal Biswas
Cleome gynandra L., commonly known as cat's whiskers, is an erect, branched, annual herb, belonging to the family Cleomaceae. The species is thought to have originated in tropical Africa and Southeast Asia, and thereafter have spread to other tropical and subtropical countries in the Northern and Southern hemispheres. Cat's whiskers is a highly nutritious vegetable and also possesses numerous medicinal

Critical period for weed control in sesame production Weed Biol. Manag. (IF 1.4) Pub Date : 2019-12-01 Zeynep Karnas, Doğan Isik, Nihat Tursun, Khawar Jabran
Planning effective weed control in cropping systems requires exact appraisal of the weed intensity and duration of their competition with the crops. This 2‐year study was carried out in order to determine the critical weed control period in sesame fields. Related and relative crop yields were monitored and analyzed using a four‐parametric log‐logistic model. We recorded data from weed‐free plots and

Chemical and environmental factors driving germination of Solanum americanum seeds Weed Biol. Manag. (IF 1.4) Pub Date : 2019-11-14 César Tiago Forte, Ubirajara Russi Nunes, Alberto Cargnelutti Filho, Leandro Galon, Leonardo Chechi, Rodrigo Roso, André Dalponte Menegat, Emanuel De Oliveira Rossetto, Milena Barretta Franceschetti
Solanum americanum Mill. is a weed that occurs with a number of crops, and it is known for its high seed production and its staggered germination. The objective of this work was to evaluate the germination behavior of S. americanum seeds under the influence of chemical and environmental factors. In the laboratory, we tested the effect on germination of (i) constant and alternating temperatures, (ii)
