One of the strategies for this is the use of nanoparticles in agriculture for disease management. This review presents a summative view on the various applications of nanoparticles in conferring disease resistance to crops and the possibility of using nanoparticles as carriers of genetic material for the generation of disease resistant crops. Nanoparticles are directly being used for the control of pathogens. Nanoparticles have been used as antiviral, antifungal and antibacterial agents. The nano-encapsulation of pesticides in controlled release matrices is one of the most promising research areas for the future. Nano-encapsulation has been shown to increase the efficiency of pesticides, reduce their volatilisation and decrease the toxicity and environmental contamination in crops. Nano-encapsulated agrochemicals or biomolecules can be engineered to be released in a controlled manner and in a target-specific location. Nanoparticles also have great scope in the field of transgenics vis-à-vis pathogen resistance. The field of agriculture can be revolutionised by the use of nanoparticles for imparting disease resistance in crops. The field is so versatile that the possibilities are endless.

However, information on the versatility and exploration of sunflower-associated bacteria as bioinoculants is less studied. Here, we present the whole-genome sequence and annotation of Stenotrophomonas maltophilia JVB5 isolated from the sunflower root endosphere from the North West province, South Africa. The whole-genome analysis revealed a genome size of 4 771 305 bp, a sequence read count of 8 764 890, a 66% guanine-cytosine content, 57 tRNAs, 268 contigs, and 4 160 protein-coding genes with functions in various metabolic pathways. Pathways involved in the indole acetic acid production were found in the S. maltophilia JVB5 genome. The whole-genome annotation predicted notable genes involved in bacterial colonisation, antibiosis, and plant growth promotion. The predicted genes are involved in the sulfur metabolism, and the oxidative stress may enhance the plant growth promotion and boost plant the resistance to stress. Upon inoculation, S. maltophilia JVB5 efficiently colonised the sunflower root under greenhouse conditions with a significant improvement on the wet plant weight of 437.20 g compared to the uninoculated control with a 331.04 g wet weight. The genomic analysis revealing specific functional genes in the bacteria genome suggests their bioprospecting in agriculture. Hence, understanding the mechanisms employed by S. maltophilia JVB5 based on the predicted multifunctional genes will help harness their bioresource in sustainable plant health.

In this study, the leaf samples of two varieties were collected from different pathogenic processes of stripe rust and powdery mildew that co-occurred in plants, and the internal transcribed spacer (ITS1) amplicon sequencing was introduced to analyse the structure and diversity of phyllosphere fungal communities. The results showed that the alpha diversity indices of the fungal communities were decreased with the pathogenic process, and the beta diversity among the different pathogenic process were significantly different as well. In addition, an Adonis analysis showed the pathogenic processes affected the structure of the fungal community, which could explain 45.6% of the variance in the community structure, on the contrary, the variety has no effect both on the community diversity and the structure. With the development of the pathogenic process, the abundance of both pathogens (Puccinia striiformis and Blumeria graminis) increased significantly, as well as for the relative abundance of some fungi (i.e., Alternaria spp., Cladosporium spp., etc.). The relative abundance of other genera (e.g., Aureobasidium, Epicoccum, etc.) increased at the early pathogenic stage, then decreased at the late pathogenic stage. Comprehensively, these fungi may have the potential to compete with pathogens for nutrients, which may be the target for the development of biological control agents.

Calotropis gigantea, Vitex negundo and Carissa macrocarpa at a concentration of 1% and 2% was investigated. The compatibility of the fungal isolate with the plant extracts was calculated using the biological index formula from the germination percentage, radial growth and spore production of BOU1. The compatibility of the plant extracts with the fungal isolate was also assessed based on the protease and lipase activities of the treated fungus. Both concentrations of plant extracts did not significantly inhibit the germination percentage, radial growth and spore production of BOU1 in a dose-depended manner. The average mean values of the biological index for the three plant extracts with two concentrations were more than 98%. The analyses of the data with the compatibility index formula suggest that irrespective of concentration, all three plant extracts were compatible with BOU1. When the plant extracts were added to the fungal isolate, the protease and lipase activities of the fungal isolate were not significantly inhibited compared to the untreated control. The reduction in all the variables of fungal growth and the enzymatic activity was less than 10% and 20%, respectively. From these findings, we can conclude that the fungal biocontrol agent C. cladosporioides BOU1 is compatible with the investigated plant extracts in terms of the fungal growth and enzymatic activities.

However, resistance of pollen beetle (Brassicogethes aeneus F.) to pyrethroids complicates the choice of suitable insecticide for the second application. The active ingredients cypermethrin, etofenprox, pymetrozine, indoxacarb and chlorpyrifos-ethyl applied as second spring applications to winter oilseed rape crops were assessed under field conditions from 2016 to 2018 to ascertain how they could reinforce the effects of the first spring application (beta-cyfluthrin) on cabbage stem weevil. Chlorpyrifos-ethyl and etofenprox strengthened the effects of the first spring spray on cabbage stem weevil markedly more than cypermethrin. Pymetrozine and indoxacarb, effective on resistant populations of pollen beetles, showed the lowest contribution to increase the effects. Indoxacarb showed a low effect on C. pallidactylus in laboratory tests too. The impacts of the bans on active ingredients chlorpyrifos-ethyl and pymetrozine are discussed.

Particularly, the seasonal occurrence of Anarsia lineatella, Grapholita molesta and Adoxophyes orana was determined during 2018 and 2020 using pheromone traps from April till October in eight peach orchards in the prefecture of Pella in northern Greece. Additionally, the accumulated degree-days (DDs) were calculated for each moth and further related to the seasonal flight patterns to determine the period of which the activity of each species starts as well as the period of the moth population peak. Moth capture data of one more year, 2021, were used to validate the risk threshold predictions. In most cases, the risk threshold predictions were at acceptable levels and especially in forecasting the start and the peak of the first and second flight period of the above three species. The first captures of A. lineatella, G. molesta and A. orana, early in the season were observed at 70, 33 and 362 DDs, respectively (lower temperature thresholds: 11.4 °C, 9.5 °C and 7.2 °C, for A. lineatella, G. molesta and A. orana, respectively, and Biofix: 1st of January in all the cases). The highest number of moth captures of A. lineatella, G. molesta and A. orana were observed at 150.6, 77.9 and 428.7 DDs, while the start of the subsequent second flight was observed at 365, 133 and 362 DDs, respectively. Moreover, the peak of the second moth flight was observed at 511.5, 204.8 and 1 239.5 DDs, for A. lineatella, G. molesta and A. orana, respectively. The current degree-day risk thresholds can be used for the precise timing of pesticides and are a prerequisite to implement automated real time decision support systems at a farm level.

Abstract: Bruchus pisorum L., is an economically important pest of field pea (Pisum sativum L.) crops worldwide, however, no fully effective methods (conventional, alternative) of its control exist now. To fill this knowledge gap, possibilities of trap cropping were tested in the years 2015-2017. Two field pea varieties differing in the start of flowering, and one spring barley variety, were used to design four different types of crops, that were compared in large plot trials (2.82 ha). It was hypothesized the females would prefer zones planted with early flowering variety for oviposition. In all three seasons, females placed more eggs on pods in the parts of plots planted with the early flowering variety, and positive aggregation of the eggs and infested seeds were recorded there too. In cases where the egg-laying period is shorter than 14-21 days, the early flowering variety located at the margins should serve efficiently as a trap crop.

In 2018, after several very warm and dry vegetation seasons, which has likely caused abiotic stress in the trees, a sudden dieback of A. concolor was observed in the city of Aranđelovac in Serbia. The external symptoms were the rapid discoloration of needles in a larger part of the crown and eventually the dieback of the trees. The aim of this study was to identify the possible agents of damage by analysing the fungal communities associated with symptomatic needles using high-throughput sequencing as no symptoms of damage were seen on the branches or stems. Symptomatic needles were collected from the lower branches of five standing trees. Half of the needles were surface sterilised and the remaining were left unsterilised. DNA was extracted, amplified using ITS2 rDNA as a marker and sequenced. Quality filtering showed the presence of 6 191 high quality reads, which, following a clustering analysis, was found to represent 79 non-singletons fungal taxa. The most common fungi in both surface sterilised and unsterilised needles were the pathogens Cytospora friesii (59.7%) and Sydowia polyspora (20.6%). The results demonstrated that C. friesii and S. polyspora can cause a rapid decline of A. concolor trees subjected to abiotic stress.
