Plant-parasitic nematodes pose a good menace to world wide agriculture. To switch biohazardous nematicides, it is needed to identify natural product or service-based brokers to fight root-knot nematodes in agriculture that are equally successful as standard nematicides.
Recently, Wang Linsong of Prof. Li Pengcheng’s group from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) has acquired nematicidal compounds with novel skeleton constructions of furyl fragments in a chemo-ecological research, which could serve as a preferable guide material for novel nematicide research and growth.
The analyze was printed in Journal of Agricultural and Food Chemistry on April 11.
The scientists isolated an Aspergillus fumigatus based mostly on the antagonistic interactions in a chemo-ecological analyze, which could induce the development of withering of the intestine and vacuole-like constructions in the nematode overall body. Primarily based on these common morphological adjustments, novel skeleton furyl compound 2-furoic acid was subsequently identified by liquid chromatography-mass spectrometry (LC-MS).
2-furoic acid confirmed helpful mortality exercise in vitro, and ongoing 2-furoic acid publicity had obvious unfavorable influences on both nematode vitality and egg hatchability. Notably, the 1T-2 fermentation broth and 2-furoic acid had significant command efficacy on Meloidogyne incognita in vivo below the greenhouse.
“Antagonistic fungi as a all-natural reservoir of possible brokers in opposition to root-knot nematodes could deliver clues for upcoming directions for their biocontrol,” stated Wang Linsong, very first writer of the research.
“This research provides beneficial insights on the use of 2-furoic acid with biocontrol likely as a precious lead compound for the advancement of new nematicides for crop protection and would enable to exploit the even further improvement of bioactive compounds of Aspergillus fumigatus from the oceans in the potential,” said Prof. Li.
Phytol could be promising for eco-helpful agrochemicals to management root-knot nematodes
