Green synthesis of demethoxycurcumin-loaded chitosan nanoparticles for the management of potato late blight caused by Phytophthora infestans.
Int J Biol Macromol
September 2025
Late blight caused by Phytophthora infestans remains a major threat to global potato production and often results in significant yield losses without effective control measures. The emergence of fungicide-resistant strains and environmental concerns associated with synthetic chemicals have intensified the search for sustainable alternatives. Here, we report the development of chitosan nanoparticles loaded with demethoxycurcumin (DM-CSNPs) as a novel solution for late blight management.

- This paper explores using Deep Learning and Visual Question Answering systems to improve the detection of wheat rust, a serious disease affecting wheat crops worldwide.
- It introduces the WheatRustDL2024 dataset, consisting of nearly 8,000 images of healthy and infected wheat leaves, designed to train models for accurate and quick disease diagnosis.
- The researchers achieved a high accuracy of 97.69% with a fine-tuned ResNet model and utilized techniques like BLIP to enhance the model’s ability to process images and text, resulting in more relevant diagnostic answers.
This study evaluates the biocontrol efficacy of three bacterial strains DTPF-3, DTBA-11, and DTBS-5) and two fungal strains ( Pusa-5SD and An-27) antagonists, along with their combinations at varying doses (5.0, 7.5, and 10.

- * The study found that isolate P. lilacinum 6887 effectively inhibited up to 97.55% of M. incognita egg hatching at higher concentrations, with several other isolates also showing strong results.
- * Gas chromatography-mass spectrometry revealed seven nematicidal compounds in these fungi, with P. lilacinum 6553 containing potent fatty acids that caused significant juvenile mortality in nematodes, indicating potential for natural pest control strategies
Background: The coronavirus disease 2019 is a serious and highly contagious disease caused by infection with a newly discovered virus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Objective: A Computer Aided Diagnosis (CAD) system to assist physicians to diagnose Covid-19 from chest Computed Tomography (CT) slices is modelled and experimented.
Methods: The lung tissues are segmented using Otsu's thresholding method.
