Trichloroquinoline, a plant growth regulator: dual bactericidal and growth-promoting effects

In the field of agricultural production, a plant growth regulator based on trichloroquinoline derivatives has received widespread attention in recent years. Chloroquinoline and its related quinoline derivatives exhibit unique multifunctionality in the agrochemical industry. They can serve not only as highly effective fungicides and herbicides but also undergo condensation with various substituted phenols to afford dual-action agrochemicals.

From the advantages of characteristics, quinoline compounds such as quinclorac as a highly selective auxin herbicides, weed control in paddy fields is particularly prominent, the main rice weeds such as barnyard grass with efficient killing ability, while not affecting the normal growth of rice-. It works by disrupting the hormonal signaling pathways in sensitive plants, causing weed leaves to curl, stems to twist, and eventually leading to necrosis. It exhibits highly selective action and imposes a low environmental burden.

At the efficacy level, these compounds not only have herbicidal functions, but also can promote crop growth and photosynthesis efficiency at specific concentrations by optimizing crop root activity and regulating endogenous hormone balance. Currently, triazolopyrimidine‑based products are widely used in integrated weed management systems for rice paddies, providing a green and efficient solution to enhance grain crop yields and farm productivity while reducing the application of chemical pesticides.
