 en Nematicide Effect Of Various Organic soil Amendments On Meloidogyne ethiopica check for this species in other resources Whitehead, 1968, On potted Vine Plants
Rivera, Lucia & Aballay, Erwin

Abstract

Five organic soil amendments were evaluated for their nematicide effect on root-knot Meloidogyne ethiopica check for this species in other resources Whitehead, 1968, on potted Vitis vinifera check for this species in other resources L. var. Chardonnay plants. The amendments included two immature composts: Compost A made with tea ( Camellia sinensis check for this species in other resources (L.) Kuntze) residues, broiler litter and grape pomace; Compost B made with tea residues, rachis and grape pomace; and separately dried tea residues, grape pomace and broiler litter. These amendments were either incorporated or applied as cover to the substrate in 5 L pots at the beginning of spring. A chemical treatment with the nematicide fenamiphos and a control with substrate only were added for comparisons. The assay was composed of 11 treatments with six replicates, with a grape plant as experimental unit. Seven months later, the assessment of the treatments was carried out based on number of second stage juvenile, nodules, eggs per root gram and reproductive index. Fresh aerial and root plant weight were also measured. The chemical treatment presented the lowest final population of M. ethiopica. When evaluating the nematicide action of the organic amendments: compost A soil-incorporated and both grape pomace and solid dry tea residue as covers obtained low reproductive indexes, similar to the chemical treatment and control (P ≤ 0.05). No differences in aerial fresh weight were determined. However, the chemical treatment showed the smallest root mass as compared to compost B and solid dry tea residues, both as cover.

 es Efecto nematicida de varias enmiendas orgánicas sobre Meloidogyne ethiopica check for this species in other resources Whitehead, 1968, en plantas de vid en macetas.
Rivera, Lucia & Aballay, Erwin

Resumen

Se realizó un experimento en macetas con plantas enraizadas de Vitis vinifera check for this species in other resources L. var. Chardonnay para evaluar el efecto nematicida de diferentes enmiendas orgánicas sobre el nematodo agallador Meloidogyne ethiopica check for this species in other resources Whitehead, 1968. Se usaron dos composts inmaduros: Compost A, elaborado con residuos de té ( Camellia sinensis check for this species in other resources (L.) Kuntze, guano de pollo seco y orujo de uva; Compost B, elaborado con residuos de té, escobajo y orujo de uva; y separadamente residuos sólidos de té; orujo de uva y guano de pollo seco. Estas enmiendas fueron aplicadas a principio de primavera, tanto en cobertera como incorporadas al suelo, considerando además un testigo químico fenamiphos y un testigo absoluto. Se determinó la población de nematodos de segundo estado juvenil (estado infestivo) de Meloidogyne spp., la cantidad de nódulos, huevos por gramo de raíz y el índice reproductivo, determinando de esta manera la tasa de reproducción de los nematodos. Además se evaluó el peso fresco de la parte aérea y de la masa radical. El testigo químico fue el tratamiento que obtuvo menor población final de Meloidogyne spp., y al evaluar la actividad nematicida de las enmiendas orgánicas, el Compost A incorporado al suelo, orujo de uva en cobertera y residuos sólidos de té en cobertera obtuvieron índices reproductivos bajos, que no fueron estadísticamente diferentes del testigo químico. En el peso fresco de la parte aérea no hubo diferencias significativas. El peso fresco de la masa radical del testigo químico presentó el valor más bajo comparado con los tratamientos de Compost B en cobertera y residuos sólidos de té en cobertera.

Palabras-clave
control de nematodos, compost, orujo de uva, residuos? De té, guano de pollo.
