Special Issue Information

Dear Colleagues,

Rice is a staple food for the majority of the world population and thus increasing and maintaining high yield is necessary. Weeds are one of the main constraints to rice productivity and their control mainly relies on herbicides. Overuse of herbicides, often having the same modes of action, has led to the occurrence of resistant weeds. Recently, the introduction of rice varieties tolerant to certain classes of herbicides has permitted the control of weeds in post-emergence without harming the crop, even though it has further increased resistance problems. Rice is often cultivated as monocropping in many areas and this can increase environmental pollution and reduce weed diversity. Weedy rice (Oryza sativa) and barnyard grass (Echinochloa spp.) are the most troublesome weeds for rice cultivation. Besides herbicides, different cultural and mechanical techniques are used to control these weeds, such as the adoption of a false seedbed, crop rotation, cover crops, etc. Abiotic stresses (i.e., salinity, extreme temperatures), which are becoming more important because of climate change, can affect rice growth but can also influence weed dynamics.

This Special Issue welcomes original papers and reviews related to weed biology, ecology, and all the topics connected to weed management in rice.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Yellow nutsedge (C. esculentus) is a perennial geophyte and invasive weed which is very difficult to control in rice and other irrigated row crops. Acetolactate synthase (ALS) inhibitors are the most commonly used herbicides to control sedges in rice. Failure to control C. esculentus was recently reported in a rice field in north-western Italy. The resistance status of this C. esculentus population was determined through a whole-plant bioassay. The mechanism underlying the resistance was elucidated, and the available chemical and non-chemical control options were discussed. The population proved to be resistant to halosulfuron and azimsulfuron at the recommended field rate. The ALS trancripts amplified from resistant and susceptible plants revealed the presence of a Pro197-to-Arg amino acid substitution in resistant plants, indicating that the resistance mechanism is target-site mediated. This is the first confirmation of herbicide resistance in C. esculentus in Europe. Resistance management should be based on an integrated approach, through the combination of diversified cultural and agronomic practices that can limit its spread and propagation through tubers.
