Plant-parasitic nematodes pose a good danger to world wide agriculture. To swap biohazardous nematicides, it is essential to recognize pure merchandise-based mostly agents to fight root-knot nematodes in agriculture that are equally helpful as common nematicides.
Lately, Wang Linsong of Prof. Li Pengcheng’s group from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) has attained nematicidal compounds with novel skeleton constructions of furyl fragments in a chemo-ecological examine, which could provide as a preferable lead materials for novel nematicide investigation and development.
The research was printed in Journal of Agricultural and Foods Chemistry on April 11.
The scientists isolated an Aspergillus fumigatus based on the antagonistic interactions in a chemo-ecological research, which could induce the formation of withering of the gut and vacuole-like constructions in the nematode entire body. Dependent on these normal morphological improvements, novel skeleton furyl compound 2-furoic acid was subsequently determined by liquid chromatography-mass spectrometry (LC-MS).
2-furoic acid confirmed helpful mortality action in vitro, and continuous 2-furoic acid publicity experienced obvious unfavorable influences on each nematode vitality and egg hatchability. Notably, the 1T-2 fermentation broth and 2-furoic acid had significant control efficacy on Meloidogyne incognita in vivo below the greenhouse.
“Antagonistic fungi as a purely natural reservoir of possible brokers in opposition to root-knot nematodes could supply clues for long run directions for their biocontrol,” stated Wang Linsong, first creator of the analyze.
“This research gives important insights on the use of 2-furoic acid with biocontrol probable as a important guide compound for the advancement of new nematicides for crop safety and would assist to exploit the even more growth of bioactive compounds of Aspergillus fumigatus from the oceans in the future,” stated Prof. Li.
Phytol could be promising for eco-helpful agrochemicals to regulate root-knot nematodes
