Abstract

Plant-parasitic nematodes are important agricultural pests and often cause serious crop losses. Novel, environmental friendly nematicides are urgently needed because of the harmful effects of some existing nematicides on human health. 5-Aminolevulinic acid (ALA) was reported as a potential biodegradable herbicide, insecticide, or plant-growth promoting agent. Lack of information on ALA against plant-parasitic nematodes prompted this investigation to determine the effects of ALA on Meloidogyne incognita, Heterodera glycines, Pratylenchus coffeae, and Bursaphelenchus xylophilus. A series of in vitro assays and one greenhouse trial were conducted to examine the nematicidal effects of ALA. The results demonstrated that ALA exhibited a strong effect of suppression against the four nematodes tested. ALA also inhibited hatching of M. incognita and H. glycines. Results from the greenhouse experiment indicated that treatment of soil with 6.0 mM ALA significantly reduced the root-gall index (RGI) and egg mass number per root system compared with the uninoculated control (P # 0.05). The metabolism assays indicated that ALA treatment significantly altered the nematode metabolism including the total protein production, malondialdehyde (MDA) content, and oxidase activities. This study suggested that ALA is a promising nematicide against plant-parasitic nematodes
