Descripción 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 composts:
Compost A made with tea (Camellia sinensis (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.
