Reação de genótipos de abacaxizeiro ao nematoide Pratylenchus Brachyurus. [PDF]

open access: yes, 2015
Os fitonematoides são considerados um dos principais fatores limitantes ao cultivo do abacaxizeiro. Estes patógenos causam danos consideráveis às raízes das plantas, diminuindo a eficiência das adubações pela redução da absorção de nutrientes. As plantas

Vertical Distribution of Rotylenchulus reniformis in Cotton Fields.

open access: yesJournal of nematology, 2011
The possible impact of Rotylenchulus reniformis below plow depth was evaluated by measuring the vertical distribution of R. reniformis and soil texture in 20 symptomatic fields on 17 farms across six states. The mean nematode population density per field, 0 to 122 cm deep, ranged from 0.4 to 63 nematodes/g soil, and in 15 fields more than half of the R.

Rotylenchulus reniformis Management in Cotton with Crop Rotation.

open access: yesJournal of nematology, 2011
One-year crop rotations with corn or highly resistant soybean were evaluated at four locations for their effect on Rotylenchulus reniformis population levels and yield of a subsequent cotton crop. Four nematicide (aldicarb) regimes were included at two of the locations, and rotation with reniform-susceptible soybean was included at the other two ...

Resistance of soybean genotypes to the reniform nematode in a controlled environment [PDF]

open access: yesCrop Breeding and Applied Biotechnology, 2013
The aim of this study was to characterize the resistance to the reniform nematode of soybean genotypes derived from crosses with at least one parent resistant to Rotylenchulus reniformis or Heterodera glicynes, or to both. Two experiments in a greenhouse

Pathogenicity and Histopathology of Rotylenchulus reniformis Infecting Cantaloup.

open access: yesJournal of nematology, 2011
Rotylenchulus reniformis was pathogenic to cantaloup (Cucumis melo 'Perlita') under greenhouse conditions. These findings confirm field symptoms of cantaloup infected with R. reniformis. Histopathological studies show that the nematode penetrates the cortex perpendicular to the vascular system and comes to rest with the head against the endodermis in ...
