Assesing the vertical movement of a nematicide in a sandy loam soil and its correspondence using a numerical model (HYDRUS 1D)
Márquez, D.; Faúndez, C.; Aballay Espinoza, Erwin; Haberland Arellano, Julio; Kremer Fariña, Cristian (Sociedad Chilena de la Ciencia del Suelo, 2017)A test under laboratory conditions was performed to typify and model the vertical movement of a nematicide (DiTera) applied at concentrations of 400, 700, and 1000 mg L-1 via drip irrigation to a sandy loam class soil ... -
Effects of rhizobacteria on parasitism by Meloidogyne ethiopica on grapevines
Aballay Espinoza, Erwin; Órdenes, Paula; Martensson, Anna; Persson, Paula (KNPV, 2013)Meloidogyne ethiopica is one of the most important plant-parasitic nematodes affecting vines in Chile and is very aggressive and difficult to control. This study evaluated 16 strains of rhizobacteria, originally isolated ... -
Efficacy and crop tolerance of 1,3-dichloropropene applied at low rates in established vineyards for the control of plant-parasitic nematodes
Aballay Espinoza, Erwin; Merino, Carlos (Elsevier, 2015)Plant-parasitic nematodes are the most important group of root pathogens affecting vineyards for fresh fruit and wine production in Chile. Due to the low efficacy of presently available nematicides and their high variability ... -
Exoenzymes and metabolites related to the nematicidal effect of rhizobacteria on Xiphinema index Thorne & Allen
Castañeda Álvarez, C.; Prodan, Simona; Rosales, I. M.; Aballay Espinoza, Erwin (Wiley-Blackwell, 2016)AimsTo identify enzymes and metabolites in the rhizobacteria filtrates that have a nematicidal effect on Xiphinema index and perform molecular characterization of the strains evaluated. Methods and ResultsA series of ... -
Nematicidal effect of rhizobacteria on plant-parasitic nematodes associated with vineyards
Aballay Espinoza, Erwin; Prodan, S.; Zamorano Carrasco, Alan; Castaneda Alvarez, C. (Springer, 2017)The action of metabolites and exoenzymes from rhizobacteria on different plant-parasitic nematodes has an influence on the nematicidal efficacy of the microbe. Seven rhizobacteria, divided into two bacterial groups, were ... -
NEMATICIDE EFFECT OF VARIOUS ORGANIC SOIL AMENDMENTS ON Meloidogyne ethiopica WHITEHEAD, 1968, ON POTTED VINE PLANTS
Rivera, Lucía; Aballay Espinoza, Erwin (INST INVESTIGACIONES AGROPECUARIAS, CENTRO REGIONAL DE INVESTIGACION QUILAMAPU, 2008-12)Five organic soil amendments were evaluated for their nematicide effect on root-knot Meloidogyne ethiopica Whitehead, 1968, on potted Vitis vinifera L. var. Chardonnay plants. The amendments included two immature ... -
Resistance assessment of grapevine rootstocks used in Chile to the root-knot nematodes Meloidogyne ethiopica, M-hapla, and M-javanica
Aballay Espinoza, Erwin; Vilches, Oscar (PUC, 2015)The rootstocks 1103 P, 101-14, K 5BB, SO4, and 3309 were assessed to determine their resistance to the three common Meloidogyne species present in Chilean vineyards, M. ethiopica, the most frequent species, M. hapla and ... -
Rhizobacteria with nematicide aptitude: enzymes and compounds associated
Castañeda Alvarez, Carlos; Aballay Espinoza, Erwin (Springer, 2016)The use of rhizobacteria to control plant parasitic nematodes has been widely studied. Currently, the research focuses on bacteria-nematode interactions that can mitigate this complex microbiome in agriculture. Various ... -
Survey of Grapevine viruses in Chile
Fiore, Nicola; Prodan, Simona; Montealegre Andrade, Jaime; Aballay Espinoza, Erwin; Pino, A. M.; Zamorano, A. (EDIZIONI ETS, 2008-03)Grapevines from six Chilean regions were surveyed for virus diseases and tested for the presence of the most important viruses. ELISA testing of 2535 samples and confirmatory RT-PCR of some ELISA-negative samples from ...
