Management of Meloidogyne javanica on tomato using agro-industrial wastes

Abstract

Summary Nematodes of the genus Meloidogyne are one of the major limiting factors in tomato production and a challenging problem in organic systems. This study aimed to investigate the effect of agro-industrial wastes, their forms of application and doses on tomato plants inoculated with Meloidogyne javanica. First, nematodes were multiplied on tomato under glasshouse conditions to simulate a naturally infested environment. At 60 days after inoculation, plant shoots were removed, new seedlings were transplanted into the pots, and the soil was amended with agro-industrial wastes. Treatments were as follows: rice husk, common bean hull, soybean hull, orange bagasse, poultry litter and waste mixture (wastes mixed in equal proportions) applied in three different forms (raw, powdered and biodigester effluent). A non-treated control and a composted waste mixture were also assessed. At 60 days after transplanting, plants were evaluated for nematode parameters. Powdered bean hulls, soybean hulls, orange bagasse and waste mixture provided the best results and were selected for dose-response investigations. A second experiment was conducted in two periods using, in addition to the selected wastes, a mixture of powdered bean hulls, soybean hulls and orange bagasse. Wastes were applied at doses of 0 (control), 2, 4, 6 and 8 t ha−1. Powdered bean hulls, soybean hulls, orange bagasse and waste mixtures at 5 t ha−1 gave the best nematode control, with reductions of 55-100%. The optimal doses for vegetative growth were 4 t ha−1 in the first period and 5 t ha−1 in the second period.

Optimizing Safe Approaches to Manage Plant-Parasitic Nematodes

“…Waste such as orange bagasse, soybean hull, rice husk, poultry litter, and common bean hull were assessed for M . javanica control in the glasshouse [ 96 ]. Their mixtures, orange bagasse, soybean hulls, and powdered bean hulls, had a range of 55–100% RKN control.…”

“…Formulating industrial wastes as value-added products for PPN control will also optimize the gaining of the related industries. Waste such as orange bagasse, soybean hull, rice husk, poultry litter, and common bean hull were assessed for M. javanica control in the glasshouse [96]. Their mixtures, orange bagasse, soybean hulls, and powdered bean hulls, had a range of 55-100% RKN control.…”

Recent Advances in the Development of Environmentally Benign Treatments to Control Root-Knot Nematodes

“…There have been very few attempts until now to use this concept for RKN management. In one of these studies, agro-industrial wastes, namely rice husk, common bean hull, soybean hull, orange bagasse, poultry litter and a mixture of equal portions of these materials were evaluated against M. javanica using pot studies in the greenhouse ( Brito et al., 2020 ). In brief, powdered bean hulls, soybean hulls, orange bagasse and waste mixtures were the most efficient wastes with RKN control ranging from 55 to 100%.…”
