“…Starting with medium-high population densities in the soil, together with an 8 month growing period in the greenhouse, allowed several nematode generations to be produced. In previous experiments carried out under controlled conditions, Robertson et al (2006) found that the "Capino pepper" population of M. incognita present in Campo of Cartagena is virulent to ATL as is the population MI-CH.…”

“…The clay-loam soil had a pH of 7.8 and 2.0% organic matter content. Before starting the experiment, nematode-susceptible peppers were cultivated in this greenhouse for three consecutive years in non disinfected soil which was naturally infested with M. incognita, race 2 (Robertson et al, 2006).…”

“…MI-CH was isolated from resistant ATL (grown in the greenhouse of our investigation) and MI-E from susceptible pepper (grown in a greenhouse where ATL was not infected). Both isolates were identified at the reference laboratory of the Consejo Superior de Investigaciones Científ icas (CSIC, Madrid) as being M. incognita race 2 "Capino pepper" (Robertson et al, 2006) in differential host tests (Hartman & Sasser, 1985). Both isolates were maintained and multiplied on tomato Marmande Claudia plants (Clause-Tezier, Almería), a cultivar susceptible to Meloidogyne.…”

“…Both M. incognita and M. arenaria are found on protected and non-protected crops in central and southern Spain López-Pérez et al, 2011), and only on protected crops close to the Atlantic coast. M. hapla is found in the northern regions of Spain and M. javanica is mainly found in the eastern and south-eastern regions (Verdejo-Lucas et al, 2002;Robertson et al, 2006).…”

“…Isolates of M. incognita have also been found infecting and reproducing on resistant peppers (Ros et al, 2005Robertson et al, 2006). After repeated cultivation of pepper grafted on rootstocks carrying the resistance genes Me3 (= Me7), populations of M. incognita capable of multiplying on resistant rootstocks have been found in some greenhouses (Ros et al, unpublished data).…”

The root-knot nematode (RKN) Meloidogyne incognita is a major soil parasite of pepper crops in greenhouses in Southeast Spain. Due to the limitations of the use of soil fumigants, grafting plants on resistant rootstocks (R-rootstocks) has become an important alternative to chemical nematicides. The repeated use of R-rootstocks can bring about the selection of virulent populations capable of overcoming resistance. We carried out a six-year investigation on resistant rootstocks in a naturally M. incognita infested greenhouse, and found that two successive years of growing plants grafted on R-rootstocks Atlante (ATL) were sufficient to overcome resistance (galling index 1.5 and 5.6 in the first and second years respectively). A large variability was observed between several R-rootstocks. Two R-rootstocks (C19 and Snooker) behaved like ATL while two others (Terrano and DRO 8801) were not infected by RKN. Laboratory studies with the same R-rootstocks, inoculated with two nematode isolates (avirulent and virulent against ATL) confirmed the greenhouse results, indicating that some rootstocks may be infested by virulent populations and others may not. It suggests that different R-genes, which are differentially overcome by RKN, have been introgressed into the rootstocks. This may have consequences for the management of resistant rootstocks in the field.

BACKGROUNDAlthough microencapsulation technology is an effective pesticide formulation method, the correlation between the release properties of microcapsules and pesticide concentrations in soil and their efficacy has not been thoroughly investigated. Here, the effects of the release properties of the nematicide Fosthiazate (FTZ) from microcapsules on their efficacy against the nematode Meloidogyne incognita were examined using experimental and mathematical approaches.RESULTSGradual release of FTZ from both polyurea microcapsules (PU‐MC) and melamine‐formaldehyde microcapsules (MF‐MC) was observed over 30 days in the release test, and each release curve was completely distinct. In the biological test, the efficacy of both microcapsules against M. incognita 42 days after the application was 8–15% higher than that of the non‐encapsulated FTZ at a concentration of 2.0 mg FTZ kg−1 soil. Soil degradation experiments suggested that the microcapsules worked effectively to protect the FTZ from degradation, which resulted in higher efficacy at a later stage. A simulation study to predict the concentration of FTZ outside the microcapsule found that the timing of supplying FTZ was important and suggested that the mixture of non‐encapsulated FTZ (non‐MC) and MF‐MC showed enhanced efficiency for the entire cultivation period in the biological test; the efficacy against nematodes was also confirmed by the measurement of nematode density using the Bearman funnel method.CONCLUSIONThe release properties of FTZ from microcapsules are critical for their effective application against M. incognita, and the established simulation study is a useful step in designing suitable release properties under complex soil conditions. © 2024 Society of Chemical Industry.
