Special Issue Information

Dear Colleagues,

The tremendous increase in crop yields has been possible in part through the utilization of chemicals for pest control. However, with the growing population in the coming decades, and the continued emergence of resistance to commercial pesticides, there is a constant need to discover new lead compounds. Natural products (NPs) with rich biodiversity and ecofriendly attributes are being discovered and developed, as exemplified by the numerous NP-based crop protection compounds. Many NPs and their derivatives have been used as bactericides, fungicides, insecticides, herbicides, plant growth regulators, and elicitors of plant immunity.

In the context of this Special Issue, we will focus on the isolation and characterization of known or new bioactive NPs, synthetic compounds inspired by NPs, semisynthetic chemicals derived from NPs, and the evaluation of their biological activities for potential applications in crop protection.

Research articles, review articles, and short communications are invited.

Dr. Wei Yan
Guest Editor

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 submissions that pass pre-check are 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 2600 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.

Equisetin was isolated from endophytic fungus Fusarium sp. JDJR1 via bioassay-guided isolation, and it was evaluated as an anti-microbial and herbicidal agent. Bioactivity assessments revealed that equisetin exhibited a broad spectrum of fungicidal and anti-bacterial activity against various plant pathogens. The EC50 values against Botrytis cinerea, Fusarium graminearum, Sclerotinia sclerotiorum, and Rhizoctonia solani ranged from 10.7 to 21.0 μg/mL. Notably, equisetin demonstrated activity against Xanthomonas oryzae pv. oryzicola, Xanthomonas oryzae pv. oryzae and Pseudomonas solanacearum with an MIC range of 4–16 μg/mL, surpassing the efficacy of the positive control: streptomycin sulfate. Equisetin, at a concentration of 100 μg/mL, could completely inhibit the spore germination of F. graminearum. In in vivo protection experiments, the protective efficacy of equisetin against B. cinerea on tomato fruits at 200 μg/mL reached 72.9%. Furthermore, in herbicidal activity tests that use the Petri dish bioassay method, equisetin had a good inhibitory effect on the root growth of weeds. At a concentration of 100 μg/mL, the inhibition rates for Echinochloa crusgalli and Eclipta prostrata root were 98.8 and 94.4%, respectively. Full article
