Glyphosate (GP, N-phosphonomethyl glycine) is one of the most popular organophosphate herbicides widely used in agricultural practices worldwide. There have been extensive reports on the biohazard attributes and hormetic impacts of GP on plant and animal systems. However, the effects of GP on plant growth-promoting microbes and its ecological relevance remain unknown.

- Tea leaves contain volatile organic compounds (VOCs) that contribute to their aroma and some may have antimicrobial properties, though their effects on bacteria are not fully understood.
- The study found that the VOCs from fresh tea leaf extract promoted cell division and production of the plant hormone indole-3-acetic acid (IAA) in a specific type of bacteria called Pseudomonas sp. NEEL19.
- Among these VOCs, 1-octanol was identified as a key compound that stimulated bacterial activity including cell division and IAA production, especially in vapor form rather than liquid, suggesting it may play a role in influencing both bacterial behavior and tea aroma.
Article Synopsis
- The study investigates the effectiveness of the fungal toxin Metarhizium anisopliae as a natural alternative to synthetic insecticides in targeting mosquito larvae like Aedes aegypti, Anopheles stephensi, and Culex quinquefasciatus.
- Using various extraction and analysis techniques, it reveals significant larvicidal activity at concentrations of 75μg/ml, achieving high mortality rates among the targeted species, with low toxicity to non-target organisms like Artemia nauplii and Eudrilus eugeniae.
- Overall, M. anisopliae metabolites show promise for pest control with less environmental impact compared to traditional chemical pesticides, as indicated by histopathological studies and the absence of
