“…When similar treatments were combined with solarization in summer, both survival and infectivity of chlamydospores of P. nicotianae and oospores of P. capsici were significantly reduced, but the high soil temperature registered was the main factor to inactivate the inoculum (Guerrero et al, 2010;Rodríguez-Molina et al, 2016). In a strawberry field trial, the combination of solarization with 2 tons ha −1 of B. carinata pellets significantly increased the percentage of plant survival with respect to the untreated control (Domínguez et al, 2014).…”

“…In a previous paper, Serrano-Pérez et al (2017a) showed that B. carinata pellets at the recommended commercial rate (3 tons ha −1 ) and the double of this (6 tons ha −1 ) decreased populations of P.nicotianae under the threshold of bioassay detection (<2 CFU g −1 of soil) and controlled the disease on pepper using autoclaved soil for the experiments. In some cases this product is not as effective when applied to natural soils (Guerrero et al, 2010;Núñez-Zofio et al, 2010;Núñez-Zofío et al, 2011). In a previous field experiment, the application of 3 tons ha −1 of B. carinata pellets in spring had no significant effect on the survival of P. nicotianae chlamydospores, regardless of the combination with Brassica cover crops (Rodríguez-Molina et al, 2016).…”

Phytophthora nicotianae is the pathogen that causes root and crown rot disease in open field paprika pepper crops of Extremadura (central-western Spain). A field experiment was established during spring, a period compatible with the pepper crop cycle in this region, to evaluate the effects of biofumigation with pellets of Brassica carinata defatted seed meal, at the rate recommended by the manufacturer (3 tons ha−1), on the survival and infectivity of P. nicotianae chlamydospores inoculum. Furthermore, three biofumigant rates (3, 6, and 20 tons ha−1) were assayed in laboratory experiments with natural soil inoculated with chlamydospores. In the field trial, the incorporation of pellets at 3 tons ha−1 did not produce remarkable changes in soil enzyme activity or soil properties. In both the field and laboratory tests, survival and infectivity in the biofumigated treatment at 3 tons ha−1 did not differ from those in the untreated control. On the contrary, the same rate added to autoclaved soil completely suppressed the inoculum, suggesting that the soil microbiota degrades B. carinata pellets before being effective against P. nicotianae. Increasing the recommended rate to 6 tons ha−1 decreased inoculum survival in the laboratory test and 20 tons ha−1 completely inhibited the inoculum, although the economic value of such a high rate application is a factor to be assessed. In phytotoxicity tests on radish and white mustard seeds with several concentrations (100, 50, 25, 10, 5, and 0%) of B. carinata pellets solution, no phytotoxic effect was observed with the two lowest concentrations, and no symptoms of phytotoxicity were found in the bioassays of pepper plants.

“…European Union restrictions on the use of chemical products, as well as the increase in the surface area dedicated to ecological agriculture, require the use of soil organic amendments for soilborne disease management. Biodisinfection using fresh sheep manure in August gives good results in controlling Phytophthora in greenhouses in southeast Spain, although this is not the case when the process is performed after the start of September (Guerrero et al, 2010). The majority of the greenhouses soils in the region are clay loam (Haplocalcids), basic pH, with an organic matter content between 1.5 and 2.5%.…”

“…In order to fit the start of the biodisinfection to the end of the cropping season it is necessary to commence in October. Using the amendments that are typically used in August (fresh sheep manure), the biodisinfection does not reduce the levels of pathogens, and are thus unviable (Guerrero et al, 2010(Guerrero et al, , 2013Lacasa et al, 2010), so it is necessary to improve the biodisinfection effects by adding amendments that strengthen the anaerobic effect or increase soil temperature, both effects by the organic matter decomposition.…”

Biodisinfection using fresh sheep manure in August is effective in controlling Phytophthora root rot in greenhouses in southeast Spain, but this is not the case after the beginning of September. The effectiveness of biodisinfection of new amendments has been evaluated beginning in October in sweet pepper greenhouses to control Phytophthora capsici. The amendments used were: T1: wheat husk + fresh sheep manure (FSM), 3.5 kg m−2; T2: sunflower pellets 3.5 kg m−2; T3: FSM: 3.5 kg m−2; T4: Control. Temperatures above 40°C were obtained in some amendments; anoxic conditions were found in all amendments, and also a reduction of the viability of P. capsici oospores with respect to the control, as well as a higher yield. The contribution of fresh sheep manure to the amendments did not lead to an improvement in their effectiveness. Autumn biodisinfection under low temperature conditions using fresh organic amendments that enhance soil anaerobic conditions may be a promising strategy for the control of P. capsici in pepper greenhouses in southeastern Spain.

“…in pepper crops (Guerrero et al, 2004a). Production increased when the application was repeated more than two years (Guerrero et al, 2004b(Guerrero et al, , 2006Candido et al, 2005), but it seemed to have little effect when applied after the beginning of September (Guerrero 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.
