Special Issue Information

Dear Colleagues,

Plant protection is undergoing a fast change towards sustainable methods. Among them, we highlight the use of plant extracts, plant products, essential oils, and other preparations as active substances or basic substances in formulations. The new products are possibly less toxic to agricultural pests in comparison with conventional ones but hopefully more environmentally friendly and less harmful to beneficial insects. In any case, fewer and fewer active ingredients remain authorized to be used as agrochemicals in Europe, and therefore, the outreach of the botanical trend includes all agricultural systems.

In this Special Issue, we welcome research papers that particularly address the following subjects:

  • Plant species with the potential to be cultivated as sources of raw materials to be used as botanical insecticides;
  • Plant products as active substances against specific agricultural pests;
  • Application of nanotechnology to the formulation of essential oils and evaluation of activity;
  • Field trials to optimize the application of botanical insecticides;
  • Integration of botanical insecticides with biological control;
  • Biostimulat effects of botanicals on crops.

The focus should be on practical case studies providing new data but with an insight into the future perspectives of this research area.

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. Plants 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 1800 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.

Global demand for food production is causing pressure to produce faster and bigger crop yields, leading to a rampant use of synthetical pesticides. To combat the nefarious consequences of its uses, a search for effective alternatives began in the last decades and is currently ongoing. Nature is seen as the main source of answers to crop protection problems, supported by several examples of plants/extracts used for this purpose in traditional agriculture. The literature reviewed allowed the identification of 95 plants whose extracts exhibit insecticide activity and can be used as bio-pesticides contributing to sustainable agriculture. The option for ethanol and/or water extracts is more environmentally friendly and resorts to easily accessible solvents, which can be reproduced by farmers themselves. This enables a bridge to be established between raw scientific data and a more practical reality. Azadirachta indica, Capsicum annuum, Nicotiana tabacum and Tagetes erecta are the most researched plants and have the potential to be viable options in the pest management approach. Azadirachta indica showed the most promising results and Brevicoryne brassicae was the most targeted pest species, being tested against the aqueous and/or ethanolic extracts of 23 different plants. Maceration using dried material (usually leaves) is the extraction method preferred by the majority of authors. Full article
