Dear Colleagues,

Currently, the production and use of biopesticides is increasing and replacing some synthetic chemical pesticides, partly in mass-produced crops, and also in niche areas, such as horticulture, greenhouses, organic farming, households, and gardens. Biopesticides offer a more sustainable solution to pest control than synthetic alternatives do. As chemical pesticides are withdrawn, owing to resistance problems or lack of commercial viability, an opportunity arises for biorational solutions. Botanical pesticides do not present the residue problems that are a matter of significant concern for consumers, who demand the application of environmentally friendly products to food commodities. For these reasons, the scientific community has focused attention on the search, production, and optimization of new plant, fungal, and agriwaste-based crop protectants.

In that context, an important means of searching for natural crop protectants is the screening of bioactive compounds from renewable natural resources, such as waste products of horticultural and agricultural production, cultivated/wild and rare plant species, as well as fungal endophytes.

In this connection, review and research papers are invited in, but not limited to, the following topics in the field of biopesticides:

  • Plant-based biopesticides
  • Fungal endophyte-based biopesticides
  • Waste-based biopesticides
  • Bioprospection and characterization of new raw sources of biopesticides
  • Metabolomic profiling of bioactive extracts, structure-activity relationships
  • Optimization of biopesticides
  • Sustainable production of biopesticides

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. Agriculture 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.

Gram-positive bacteria Bacillus subtilis B068150 has been used as a biocontrol agent against the pathogen Fusarium oxysporum cucumerinum. Cucumber was grown in three soils with strain B068150 inoculated in a greenhouse for 90 days, and the colonization ability of strain B068150 in cucumber rhizosphere and non-rhizosphere soils was determined. Changes in total bacteria and fungi community composition and structures using denaturing gradient gel electrophoresis (DGGE) and sequencing were determined. Colony counts showed that B068150 colonization in the rhizosphere was significantly higher (p < 0.001) than in non-rhizosphere soils. Based on our data, the introduction of B. bacillus B068150 did not change the diversity of microbial communities significantly in the rhizosphere of three soils. Our data showed that population density of B068150 in clay soil had a significant negative correlation on bacterial diversity in cucumber rhizosphere in comparison to loam and sandy soils, suggesting that the impact of B068150 might be soil specific.
