Plant-parasitic nematodes pose a terrific risk to global agriculture. To switch biohazardous nematicides, it is important to discover pure products-centered agents to beat root-knot nematodes in agriculture that are similarly successful as conventional nematicides.
Lately, Wang Linsong of Prof. Li Pengcheng’s team from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) has received nematicidal compounds with novel skeleton structures of furyl fragments in a chemo-ecological review, which could provide as a preferable direct materials for novel nematicide investigation and improvement.
The research was released in Journal of Agricultural and Foodstuff Chemistry on April 11.
The scientists isolated an Aspergillus fumigatus primarily based on the antagonistic interactions in a chemo-ecological research, which could induce the development of withering of the gut and vacuole-like constructions in the nematode entire body. Based mostly on these typical morphological changes, novel skeleton furyl compound 2-furoic acid was subsequently identified by liquid chromatography-mass spectrometry (LC-MS).
2-furoic acid showed productive mortality action in vitro, and continual 2-furoic acid exposure had apparent damaging influences on each nematode vitality and egg hatchability. Notably, the 1T-2 fermentation broth and 2-furoic acid experienced important management efficacy on Meloidogyne incognita in vivo beneath the greenhouse.
“Antagonistic fungi as a natural reservoir of possible brokers in opposition to root-knot nematodes could supply clues for upcoming directions for their biocontrol,” explained Wang Linsong, initial writer of the review.
“This review delivers beneficial insights on the use of 2-furoic acid with biocontrol probable as a precious direct compound for the improvement of new nematicides for crop safety and would aid to exploit the further more growth of bioactive compounds of Aspergillus fumigatus from the oceans in the potential,” reported Prof. Li.
Phytol may be promising for eco-pleasant agrochemicals to manage root-knot nematodes
