Journal of Plant Protection Research is an international peer-reviewed journal that publishes original papers, rapid communications, reviews, covering all areas of plant protection. Subjects include phytopathological virology, bacteriology, mycology and applied nematology and entomology as well as topics on protecting crop plants and stocks of crop products against diseases, viruses, weeds etc.
The Journal is published by Institute of Plant Protection – National Research Institute and Committee on Agronomic Sciences of the Polish Academy of Sciences. By 1997 under the title Prace Naukowe Instytutu Ochrony Roślin and Annals of Agricultural Sciences - Series E - Plant Protection).
JPPR publishes original research papers, rapid communications, critical reviews, and book reviews covering all areas of modern plant protection. Subjects include phytopathological virology, bacteriology, mycology and applied nematology and entomology as well as topics on protecting crop plants and stocks of crop products against diseases, viruses, weeds etc. We publish papers which use an interdisciplinary approach showing how different control strategies can be integrated into pest management programmes, which cover high and low input agricultural systems worldwide, within the framework of ecologically sound and economically responsible land cultivation.
Relevant topics include: advanced methods of diagnostic, and computer-assisted diagnostic plant research and new findings, biological methods of plant protection, selective chemical methods of plant protection, the effects of plant-protecting agents and their toxicology, methods to induce and utilize crop resistance, application techniques, and economic aspects of plant protection.

This study was executed to investigate the potential of agar-agar, a nontoxic and non-degradable
gelling agent, as a promising coating agent to improve and protect banana fruit
against fungal postharvest diseases i.e., crown, finger, neck and flower end rots which are
caused by fungal isolates of Colletotrichum musae and Fusarium moniliforme. Coated-ba-nana
fruit samples with different concentrations of agar-agar suspension particularly at
2.0 g · l−1 exhibited a significant reduction in incidence and severity of postharvest diseases
compared to untreated fruit. Banana fruits dipped in agar suspension at 2.0 g · l−1 for 5, 10
and 15 min showed significant reduction in disease incidence and severity. Moreover,
application of agar suspension as a coating agent at 2.0 g · l−1 significantly decreased
weight loss (%), firmness loss (%), and soluble solid concentration of banana fruit for
15 days at 25 ± 2°C. Scanning electron microscopy observation confirmed that the fruit
coated with agar colloid at 2.0 g · l−1 had significantly fewer cracks and showed smoother
surfaces than untreated fruit. This explains the quality improvement in agar-coated fruit
compared to uncoated fruit. Overall, agar colloid, a safe coating agent, could be used to
protect banana fruit against postharvest rot diseases and extend fruit storage life during
ripening and storage.
