“…The process of soil disinfection was called "biodisinfestation" by Núñez-Zofio et al (2011). In these processes, the effects of anaerobiosis and suppression are added to the effect of temperature and of the gases released during decomposition of the organic matter, such as ammonia and nitrous acid (Lazarovits, 2001;Arriaga et al, 2011). Although the characteristics of the OM are regarded as critical elements for the control of pathogens in general, the same characteristics do not seem to have a great impact on the control of some pathogens produced in anaerobic conditions (Bonanomi et al, 2007(Bonanomi et al, , 2010.…”

The nematode Meloidogyne incognita is responsible for substantial losses in greenhouse-grown peppers in south-eastern Spain. This study evaluates the use of biodisinfestation (BS) (organic amendment + solarisation) as an alternative to using methyl bromide (MB) over three consecutive years to control the nematode in greenhouse conditions. Brassica carinata (BP) pellets or B. carinata (BP) + fresh sheep manure (M) were evaluated in treatments which began on two different dates (August and October) and the results were compared with MB-disinfested and untreated controls. During the third year, the gall index for BP was lower than that obtained for BP+M and in the August treatment than in the October treatment. The commercial crop of pepper fruit obtained with the biodisinfestation treatments begun in August was similar to or higher than that obtained with MB, and higher than that obtained with both October biodisinfestation treatments. The yield of the October biodisinfestation treatments was higher than that of the untreated one. In August of all the years studied, the accumulated exposure times were greater than the thresholds required to kill M. incognita populations at 15 cm depth. The incidence of the nematode did not correspond to the reduction achieved during solarisation, and seemed to increase during the crop cycle. Further studies should look at why high temperatures do not produce a sustained reduction in the populations of Meloidogyne incognita.

“…Then, we concluded that biodisinfection treatments were most likely leading to increased soil suppressiveness through a stimulation of the activity of soil microbial communities. On the other hand, it is critical to reduce the dose of organic amendment as much as possible in order to minimize its potential adverse impact on environmental quality, including the emission of greenhouse gases previously reported (Arriaga et al, 2011). In this respect, we hypothesized that repeated biodisinfection might allow for a reduction in amendment dose.…”

“…Before treatment application (see below), experimental plots were artificially infested as described in Arriaga et al (2011). Briefly, pepper root balls containing mycelium, sporangia, zoospores and oospores of five different strains (see below) of P. capsici were buried at 10 cm soil depth using a completely randomized block design with three replicates and a plot size of 28.2 m 2 (6 × 4.7 m).…”

“…Similarly, Table 2 shows the dosage and time of application of amendments. Due to the risks of greenhouse gas emissions (Arriaga et al, 2011) and water pollution by nitrates (OJ, 1991), animal amendment dosage was progressively reduced so that, in the third application, an amount equivalent to 170 kg ha -1 of mineralized nitrogen was applied in each plot (limit established by the European Union 91/676/EEC Nitrates Directive).…”

Phytophthora root and crown rot is a plant disease responsible for important economic losses in protected pepper crops. A greenhouse experiment was carried out in a temperate climate region (northern Spain) to assess the effects of repeated biodisinfection after three consecutive crop seasons with different organic amendments (a non-composted mixture of sheep manure and chicken litter, a semicomposted mixture of horse manure and chicken litter, Brassica carinata dehydrated pellets plus Sinapis alba fresh green manure) on disease incidence, crop yield and soil quality. Biodisinfection treatments were found to improve soil water properties through reduction in soil bulk density and increased water infiltration. Biodisinfested soils showed higher values of physicochemical and microbial properties than control (untreated) and plastic-mulched soils. In plots treated with the non-composted or semicomposted mixture, the observed higher levels of microbial activity were strongly related with an increase in soil microbial biomass. Brassica-Sinapis treatment had a weaker effect on soil properties than animal manure-based treatments. However, highest counts of total bacteria, actinomycetes and Pseudomonas spp. were found in BrassicaSinapis-treated soils. It was concluded that repeated biodisinfection for the control of Phytophthora root and crown rot in protected pepper crops located in temperate climate regions can improve soil quality and suppressiveness, as well as allow for a reduction in the dose of organic amendment needed for biodisinfection. Among the studied organic amendments, the semicomposted amendment was the best option in terms of reduction in disease incidence.Additional key words: biofumigation; organic amendment; soil microbial properties; soilborne plant pathogens; solarization; suppressiveness.

En una región de clima templado (norte de España) se realizó ensayo en invernadero para evaluar la reiteración de tratamientos de biodesinfección después de tres ciclos de cultivo consecutivos con diferentes enmiendas orgánicas (mezcla no-compostada de estiércol de oveja y gallinaza, mezcla semicompostada de estiércol de caballo y gallinaza, pellets deshidratados de Brassica carinata más Sinapis alba como abono verde fresco) sobre la incidencia de la enfermedad, la producción y la calidad del suelo. La biodesinfección mejoró las propiedades hídricas del suelo al reducir la densidad aparente y aumentar la infiltración. Los suelos biodesinfectados mostraron valores más altos en las propiedades físico-químicas y microbianas que los suelos control (no tratado) y acolchado con plástico.
