“…Chitosan activity has shown activity against several species of seedborne pathogens (Table 1). Treating pearl millet with chitosan under field conditions reduced infection of Magnaporthe grisea (Bhardwaj et al, 2022), and on seeds of Triticum spelta, reduced the severity of Fusarium culmorum (Buzón-Durán et al, 2020). Under greenhouse conditions, groundnut seed treatment with chitosan and chitosan-polyethylene glycol blend containing Trichoderma harzianum led to a decrease of Aspergillus niger infections (Prasad et al, 2020).…”

Seed is a critically important basic input of agriculture, because sowing healthy seeds is essential to food production. Using high quality seed enables less use of synthetic pesticides in the field. Seedborne pathogens can reduce yield quantity and quality of the crops produced. Seed treatments protect plant seedlings from pathogen attacks at emergence and at the early growth stages, contributing to healthy crop plants and good yield. However, there is increased concern about the application of synthetic pesticides to seeds, while alternatives are becoming increasingly addressed in seedborne pathogen research. A series of strategies based on synthetic fungicides, natural compounds, biocontrol agents (BCAs), and physical means has been developed to reduce seed contamination by pathogens. The volume of research on seed treatment has increased considerably in the past decade, along with the search for green technologies to control seedborne diseases. This review focuses on recent research results dealing with protocols that are effective in the management of seedborne pathogens. Moreover, the review illustrated an innovative system for routine seed health testing and need-based cereal seed treatment implemented in Norway. Graphical Abstract

“…In this experiment, the radicle length of fenugreek seedlings due to chitosan (0.5 g L −1 ) was significantly higher (3.76 cm) over the control (2.26 cm) and carbendazim (3.34 cm). Bhardwaj et al [33] evaluated different pearl millet (Pennisteum glaucum) seed treatments including chitosan that were sown in several experiment fields in India regarding blast disease caused by Pyricularia grisea. The application rate of chitosan seed immersion was 0.5 g kg −1 per liter of water and resulted in a blast severity reduction ranging from 4.7% to 26.9%, depending on the field location and growing season.…”

Seedborne pathogens represent a critical issue for successful agricultural production worldwide. Seed treatment with plant protection products constitutes one of the first options useful for reducing seed infection or contamination and preventing disease spread. Basic substances are active, non-toxic substances already approved and sold in the EU for other purposes, e.g., as foodstuff or cosmetics, but they can also have a significant role in plant protection as ecofriendly, safe, and ecological alternatives to synthetic pesticides. Basic substances are regulated in the EU according to criteria presented in Article 23 of Regulation (EC) No 1107/2009. Twenty-four basic substances are currently approved in the EU and some of them such as chitosan, chitosan hydrochloride, vinegar, mustard seed powder, and hydrogen peroxide have been investigated as seed treatment products due to their proven activity against fungal, bacterial, and viral seedborne pathogens. Another basic substance, sodium hypochlorite, is under evaluation and may be approved soon for seed decontamination. Potential basic substances such as essential oils, plant extracts, and ozone were currently found effective as a seed treatment for disease management, although they are not yet approved as basic substances. The aim of this review, run within the Euphresco BasicS project, is to collect the recent information on the applications of basic substances and potential basic substances for seed treatment and describe the latest advanced research to find the best application methods for seed coating and make this large amount of published research results more manageable for consultation and use.

“…Currently, pearl millet is grown on 6 hundred thousand hectares in USA (Myers 2002) and 5 million hectares in Brazil (França & Miyagi 2012) as a forage crop. Recently, it has expanded area to about 1 million hectares in India as a forage/fodder crop https://doi.org/10.17221/93/2022-CJGPB in summer as well as in the rainy season and farmers are demanding high yielding single/multi-cut cultivars with a better forage quality to meet their livestock feed demands (Amarender Reddy et al 2013;Bhardwaj et al 2022).…”

The lignin content of forage crops significantly affects the livestock's forage intake and its dry matter digestibility. The brown midrib (bmr) trait is known for its association with a reduced lignin content and increased digestibility. Pearl millet inbreds having the bmr trait were derived from two populations ICMV bmr and WRajPop bmr via continued selfing up to 6-8 generations. The results from the crosses revealed the presence of the same single recessive gene that controlled the bmr in both the populations. The stable expression of the bmr gene in the new genetic background indicated that there was no effect of modifier genes. Four inbreds were identified with the stable expression of bmr (three in ICMV 155 and one in the WRajPop background) with a high biomass potential, which can serve as a bmr source in future pearl millet forage breeding programmes.
