“…Interestingly, the microscopic examination of the treated F. graminearum showed dehydration and deformation in mycelial growth. During the greenhouse experiments, by using as host plant the cultivar Falat (bread wheat) they observed a disease severity of 29% and 27% in chitosan and chitosan nanoparticles treated plants, while the plants treated with the tilt fungicides reached 0.33% of disease severity after three weeks of inoculation [ 55 , 56 ]. Another study [ 57 ] combined chitosan with a plant biostimulant, the liquid seaweed extract (LSE) from a brown macroalga and evaluated the efficacy of chitosan and LSE, alone or combined, against F. graminearum growth.…”

Fusarium head blight (FHB) is a devastating disease for cereals. FHB is managed by fungicides at anthesis, but their efficacy is variable. Conventional fungicides accumulate in the soil and are dangerous for animal and human health. This study assayed the antifungal ability of chitosan hydrochloride against Fusarium graminearum. Chitosan reduced F. graminearum growth and downregulated the transcript of the major genes involved in the cell growth, respiration, virulence, and trichothecenes biosynthesis. Chitosan promoted the germination rate, the root and coleoptile development, and the nitrogen balance index in two durum wheat genotypes, Marco Aurelio (FHB-susceptible) and DBC480 (FHB-resistant). Chitosan reduced FHB severity when applied on spikes or on the flag leaves. FHB severity in DBC480 was of 6% at 21 dpi after chitosan treatments compared to F. graminearum inoculated control (20%). The elicitor-like property of chitosan was confirmed by the up-regulation of TaPAL, TaPR1 and TaPR2 (around 3-fold). Chitosan decreased the fungal spread and mycotoxins accumulation. This study demonstrated that the non-toxic chitosan is a powerful molecule with the potential to replace the conventional fungicides. The combination of a moderately resistant genotype (DBC480) with a sustainable compound (chitosan) will open new frontiers for the reduction of conventional compounds in agriculture.

“…The antimicrobial activity of chitosan nanoparticles (CS/NPs) has been recently studied and it has been demonstrated that CS/NPs has the ability to control of Fusarium head blight of wheat. Kheiri et al (2016) demonstrated that CS/NPs have significant inhibitory effects on the fungal growth, colony formation and conidial germination of F. graminearum. They also revealed that plant protection by CS/NPs is dependent on time period.…”

Wheat (Triticum aestivum) is main staple food grain crop, grown in a range of environments over an area of 221.6 million hectares (M ha) with an annual production likely to reach more than 750.4 million metric tons in 2016-17 (Foreign Agricultural Service, USDA, 2018). Despite of this significant growth, the world population in some parts is still facing hunger crisis due to insufficient availability of food grains. To meet the future food demands imposed by overwhelming increasing population which is expected to reach nine billions in 2050, the world wheat production must continue to increase by 2% annually. This challenge of increasing wheat production is daunting as the wheat cropping system at present is constrained by climatic fluctuations, poor soil health and has increased risk of epidemic outbreak of diseases and insect-pests. To address these challenges, innovative technologies with a potential of increasing the sustainability of the present day cropping systems are required to be introduced in modern agriculture. Among these technological advancements, nanotechnology is gathering significant contemplations due to its wide spectrum applications in agriculture and allied sectors. It has a wider application in the field of crop production, food security, sustainability and climate change and is being utilized for developing several precise tool sets like nanofertilizer, nanopesticide, nanoherbicide, nanosensor and smart delivery systems for controlled and sustained release of agrochemicals. Recent research evidences indicated that intervention of nanotechnology in wheat farming is still in its early stages, although have bright prospects for efficient nutrient utilization through nanoformulations of fertilizers, breaching yield barriers through bionanotechnology, surveillance and management of pests and diseases and development of new-generation pesticides etc.

This study compared the effectiveness of fungal chitosan nanocomposite, chitosan gel and chitosan nanoparticles against strawberry phytopathogenic fungi (Botrytis cinerea; Rhizopus stolonifer and Aspergillus niger). Nanoparticles were prepared by ionic gelation method and characterised by dynamic light scattering and scanning electron microscopy. The influence of the edible coatings on fungal growth was analysed in vitro and in vivo The fungal chitosan nanoparticles presented an average size = 331.1 nm (AE7.21) with a narrow size distribution (PDI = 0.377) and a zeta potential = +34 mV. The edible coating made by the nanocomposite exhibited important changes in fungal morphology, and the best control of the growth of the assayed fungal strains in artificially infected strawberries. Therefore, nanotechnology brought some benefits to the conventional chitosan gel edible coating, improving its antifungal activity and forming a new eco-friendly coating.
