TL;DR: The objectives of this study were to understand the factors influencing FAW damage in African smallholder maize fields and quantify its impact on yield, using two districts of Eastern Zimbabwe as cases.

TL;DR: It is concluded that Et-AgNPs are helpful for the management of M. incognita and will be an effective replacement for synthetic nematicides.

TL;DR: It is shown that combining chemical and biological nematicides can successfully control the root-knot nematode M. incognita and increase yields.

TL;DR: The risk matrix described here presents a quantitative approach to the evaluation of the resistance risk posed by the use of herbicides and achieves a better harmonisation of herbicide resistance risk assessment across Europe.

TL;DR: Results indicate that synthesized ZnO NP could promote growth and induce systemic resistance in pearl millet against S. graminicola and can be effectively used to manage downy mildew.

TL;DR: Overall, soil application of fluopyram shows potential to be a component of an integrated pest management strategy for the control of B. longicaudatus populations on strawberry in Florida.

TL;DR: It was determined that no specific instrument is guaranteed to reduce pesticide use, but mixes of instruments, with varying degrees of authoritative force, applied at multiple scales with stakeholder collaboration were identified as beneficial to reducing farmer pesticide use.

TL;DR: This work focuses on the advantages and drawbacks of endotherapy with respect to environmental concerns and the risks for tree and human health, and discusses the factors that influence the effectiveness of the trunk injection.

TL;DR: Investigation of the fumigant effect of lemongrass essential oil and citral on the reproductive cycle, sexual behavior, lipid composition and the enzymatic activity of biotransformation enzymes in cowpea weevils found changes may affect the survival, energy resource transfer during oogenesis and oviposition, which are likely mechanisms involved with essential oil toxicity.

TL;DR: The results from this study indicated that fluopyram was effective against M. incognita and could be used for control of root-knot nematodes in tomato production, while enhancing tomato growth and yield.

TL;DR: The multi-suppressive properties of composts from agricultural residues, agro-industrial co/by-products, and plant green-waste showed the most complex microbiome structure, which included either biocontrol agents associated with the control of Rhizoctonia damping-off in bean and Verticillium wilt in eggplant or microbial consortia for controlling Pythium damping off in cucumber and zucchini.

TL;DR: This approach entails a fundamental shift in the contours of action, from a conventional, often individual and independent approach of systematic or symptomatic interventions at a field scale, to collective organisation and management of ecosystem services at a territory scale, also including ecological, economic and social dimensions.

TL;DR: A pre-conditioning period of only 14 days was found to be effective for disease suppression, which can substantially improve its practical utility for nurseries.

TL;DR: Results indicate that early spring/early fall application of B. firmus is an effective biopesticide treatment for management of the southern root-knot nematode and P. lycopersici on tomato crops growing in the integrated pest management system of this experiment and in the environmental conditions of southern Italy.

TL;DR: The response of advanced breeding lines to field infection by cassava brown streak viruses (CBSVs) and cassava mosaic begomoviruses (CMBs) is determined and these two cassava clones should be utilized in CBSD and CMD management in Uganda, including their utilization as progenitors in further virus resistance breeding.

TL;DR: None of the OMRI-listed compounds evaluated in this study provided effective control, indicating anticipated difficulty among organic producers in reducing damage from this new and important pest.

TL;DR: It is demonstrated that disease severity of Ascochyta blight in chickpea can be monitored using remote sensing methods under active field conditions and hyperspectral sensing was found to be useful in predicting disease severity.

TL;DR: Experiments using an air assisted greenhouse sprayer and artificial plants with attached fruits were conducted to investigate the effects of volume rate, target location, and airflow rate on spray deposition and distribution uniformity on leaves, fruits and losses to the ground, indicating that volume rate significantly influenced deposition and distributed uniformity.

TL;DR: 28 different risk mitigation options that can be used in a systems approach in Australia are discussed and some measures such as awareness and exclusion are common across all three levels.

TL;DR: The potential economic benefits of the newly developed wheat variety BARI Gom 33 in Bangladesh far exceeds its dissemination cost by 2029–30, and international funder agencies are urged to support the national system in scaling out the new wheat variety and wheat research in general.

TL;DR: Advances on the techniques used to obtain, assess, and apply plant extracts for antifungal activities on horticultural produce are discussed.

TL;DR: Results are promising and indicate that the BtEO might be further investigated as natural alternative to synthetic fungicides for the control of rots on grapes diseases.

TL;DR: A novel Unmanned Aerial Vehicle (UAV) system incorporating bird psychology for efficient bird damage control is proposed, designed to engage birds’ well-established abilities to learn to recognise and avoid novel predators, thus providing the benefit that a long-term fear response towards the UAV can be expected.

TL;DR: The results indicated that the developmental duration of S. furcifera pre-adult, adult, female adult longevity and the total preoviposition period (TPOP) treated with LC10 dose were all significantly prolonged compared to the control or the LC25 dose.

TL;DR: It is concluded that anthracnose, fruit and stem rot, stem canker and the cactus viral disease are among the most frequently reported diseases of dragon fruit and actions are needed to address the growing problems associated with these diseases as effective, sustainable and practical management strategies are yet to be identified.

TL;DR: The degree of resistance depended on the geographic location of each psyllid population and on the insecticide, with imidacloprid resistance most prominent in psyllids from LRGV.

TL;DR: The plant extracts, bioagent and new generation fungicides that showed high inhibition to R. solani under in vitro were evaluated for their efficacy against sheath blight disease under greenhouse and field experiments.

TL;DR: A source of resistance was identified using natural and artificial screening against chilli leaf curl virus disease (ChiLCVD) and it was suggested that the resistance carried by S-343 is controlled by a single dominant gene.

TL;DR: A working regulatory system for agricultural pesticides requires interactions between producers, state and federal government, and third-party testing laboratories, along with educational programs to train growers appropriate best management and pest management practices for their business model.

TL;DR: The competitive displacement and the performance results were the same, indicating the most suitable host for each species, and no advantage was observed for one particular species in the absence of insecticides.
