“…Momma et al (2006) also showed that VFAs are factors contributing to suppression of soil-borne pathogens by RSD. Volatile fatty acids have long been known for their nematicidal effects (Stephenson, 1945;Johnston, 1959;Banage and Visser, 1965;Nagase et al, 1982;Bansal and Bajaj, 2003;Browning et al, 2004;McElderry et al, 2005) and noted as a group of naturally occurring chemicals during decomposition (Sayre et al, 1965;Hollis and RodriguezKabana, 1966;Elmiligy and Norton, 1973;Lynch, 1978;Badra et al, 1979;Djian et al, 1991;McBride et al, 2000;Chitwood, 2002). Differences in nematicidal activity were found among VFAs (Stephenson, 1945;Johnston, 1959;Badra et al, 1979;Bansal and Bajaj, 2003;McElderry et al, 2005), and that of acetic acid was lowest (Nagase et al, 1982).…”

“…In addition, pH of aqueous solution is known to exert intense influence on the nematicidal effect of VFAs (Stephenson, 1945;Sayre et al, 1965;Banage and Visser, 1965;Hollis and Rodriguez-Kabana, 1966;Elmiligy and Norton, 1973;Djian et al, 1991;McElderry et al, 2005). We also showed that pH greatly influenced the nematicidal effect of VFAs (Table 4 and Fig.…”

“…The mode of action, however, has not yet fully been revealed. Short-chain volatile fatty acids (VFAs) contained in organic matter or produced through the decomposition of the organic matter were pointed out as a factor of the action mechanism (Sayre et al, 1965;Hollis and RodriguezKabana, 1966;Lynch, 1978;Badra et al, 1979;McBride et al, 2000).…”

“…Previous studies have revealed that the application of biogas digestate reduced the severity of damage to tomato by root-knot nematodes [28] and to sugar beet by Heterodera schachtii [29]. Several toxic compounds are involved in nematode suppressive properties, such as ammonia [30,31], fatty acids [32], chitin, release of plant-specific toxins etc. [33].…”

This study investigated the effects of biogas digestate application to soil with rice straw on nitrate leaching potential and nematicidal activity toward root-knot nematodes Meloidogyne incognita. The following seven treatments were set up: (i) control (CONT); (ii) chemical fertilizer (CF); (iii) wet biogas digestate derived from pig manure (WBD); (iv) and (v) dry biogas digestate derived from a mixture of pig manure and rice straw at an initial C/N ratio of 20 and 30 (DBD20 and DBD30); (vi) and (vii) DBD20 mixed with rice straw to adjust the C/N ratio to 16 (Mix1) and 30 (Mix2), respectively. The application rate of CF and digestates was adjusted to 200 mg N kg−1 soil based on the inorganic ammonium nitrogen contents. Nitrate contents readily increased in all the treatments with incubation, except for Mix2, and those at day 90 were decreased with increasing initial labile C contents. Garden balsam was grown as a test plant for root-knot nematodes using the soils at day 90 and the results showed that the gall index was significantly lower in Mix2 and Mix1 than in CF. These results suggest that dry digestate mixed with rice straw might have potential for lower nitrate leaching and nematicidal properties.

This laboratory study evaluates the biofumigant effect of different organic materials with the aim of developing non-chemical alternatives for the management of Meloidogyne incognita (Kofoid & White) Chitwood populations. Sources of organic material from the production system were selected with the aim of reducing agricultural residue accumulation problems as well as decreasing the costs due to the use of chemical fertilizers and pesticides. The selected materials were residues from pepper, strawberry, tomato and cucumber crops, orange juice industry residues, commercial manure and sheep manure, applied at different dosages. Two biofumigation assays were performed under laboratory conditions, using alkaline soils from the Torreblanca area (Murcia, Spain) and acidic soils from the Villa del Prado area (Madrid, Spain). The assays evaluated the effect of the treatments on M. incognita juveniles and other soil organisms, the nematode galling index on tomato roots (susceptible cv. Marmande) grown in the biofumigated soil and soil fertility parameters. The results showed that all biofumigant materials significantly decreased M. incognita populations and galling indices in tomato cv. Marmande. A greater effect was observed on galling indices when applying crop residues together with manure than with the residues alone. Biofumigation had a general beneficial effect on soil fertility, generally increasing nitrogen, organic carbon, pH and potassium levels, and also calcium levels when crop residues of pepper and strawberry were applied. There were no important variations in the number of saprophagous nematodes, dorylaimids and enchytraeids.
