Emerging Topics in Botanical Biopesticides—2nd Edition

Dear Colleagues,

The increase in world population and advances in the agricultural industry have contributed to global warming. Additionally, it has been discovered that pests can grow in abundance and generate resistance to applied synthetic pesticides. Each year, herbivorous insects and phytopathogenic fungi destroy up to a fifth of the world's agricultural production. This increase in the population of pest insects is also due to human-manipulated habitats, where crops are selected and grouped in one confined area. In this way, it not only favours the needs of humans but also those of phytophagous organisms. Above all, these pests can widely proliferate in tropical and subtropical regions due to climatic conditions.

Many plants produce secondary metabolites that have evolved along with the development of insects, and they have various defence functions against phytophagous insects. Many of these natural products are useful as insecticides, fungicides, and manipulators of insect behaviour. Furthermore, these compounds are safe for the environment and human health. Secondary plant metabolites, especially essential oils or their components, could be a natural source for the design of biopesticides. On the other hand, biological interactions, such as those between plants and microorganisms, are a source of new natural products that can be used to control and manage insect pests. It is also important to be familiar with the regulations and legislation that may exist or arise as these new products are applied. Finally, it is important to consider economic aspects, such as the cost of production and storage, arising from using these new botanical pesticides. Nowadays, essential oils already have an international market and cultivation areas. That is why this Special Issue will instead be dedicated to using natural compounds to manage agricultural pests.

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. Plants is an international peer-reviewed open access semimonthly 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 2700 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.
