Evaluation of the in vitro Response of Meloidogyne incognita to silver nano particle liquid from Agricultural wastes. Agrivita Journal of Agricultural Sciences 43(3): 524-534.https://uilspace.unilorin.edu.ng/handle/20.500.12484/11111Plant-parasitic nematodes attack is an important problem on crop production worldwide. Meloidogyne javanica is a potentially damaging pest of several crops. Laboratory studies were conducted to examine the effect of supernatant liquid from the synthesis of silver nanoparticles with agricultural wastes on the survival and hatching of Meloidogyne javanica juveniles and eggs. The experiment consisted of five treatments (carbofuran, corn cobs, rice husk, guinea corn chaff, and a distilled water control) at three concentrations of 10, 20, and 30%. Each was repeated three points in a complete randomized design. Nematicidal bioassay revealed a consequential (p=0.05) decrease in egg hatch rate in 20 and 30% concentrations of the nanoparticle supernatant liquid. Similarly, percentage mortality increased significantly (p=0.05) in the nano supernatant liquid, with the corncob silver nanoparticle having the highest percentage of mortality. These results concluded that the agricultural waste of silver nanoparticle supernatant liquid could be cost-effective and eco-friendly of nematicideenResearch Subject Categories::FORESTRY, AGRICULTURAL SCIENCES and LANDSCAPE PLANNINGBio-pesticide Environmental pollution Nematodes Toxicity Synthetic nematicidesArticle
