Insecticidal Activity of Trichilia hirta L. (Sapindales: Meliaceae) Extracts Against Spodoptera frugiperda (Lepidoptera: Noctuidae) Larvae and the Identification of Bioactive Compounds

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Fruits of Trichilia hirta were extracted and fractionated according to solvent polarity. The resulting partitions were screened for insecticidal activity by evaluating larval mortality and weight after 7 and 14 days. LC‐MS analysis of the most active fraction enabled the annotation of secondary metabolites potentially associated with the observed ...

Managing Brown Rot Disease of Citrus Fruit Using Plant Extracts

Journal of Phytopathology, Volume 174, Issue 2, March/April 2026.
ABSTRACT Brown rot, caused by Phytophthora nicotianae and P. citrophthora, is a major disease of citrus fruit, leading to significant economic losses globally. Conventional fungicides are commonly used to manage this disease, but concerns have been raised due to environmental persistence, human toxicity and the emergence of resistant strains.
