Nematode Management in Okra

J. W. Noling

Plant-parasitic nematodes are small microscopic roundworms that live in the soil and attack the roots of plants. Crop production problems induced by nematodes therefore generally occur as a result of root dysfunction; nematodes reduce rooting volume and the efficiency with which roots forage for and use water and nutrients. Many different genera and species of nematodes can be important to crop production in Florida. In many cases a mixed community of plant-parasitic nematodes is present in a field, rather than having a single species occurring alone. Okra is infamous for its susceptibility to root-knot nematodes; it is also extremely sensitive to sting nematodes. Because of this, okra should not be planted in land known to have severe problems with these nematodes in recent crops.

Nematode Management in Tomatoes, Peppers, and Eggplant

J. W. Noling

Plant parasitic nematodes are small microscopic roundworms that live in the soil and attack the roots of plants. Crop production problems induced by nematodes, therefore, generally occur as a result of root dysfunction, reducing rooting volume and foraging and utilization efficiency of water and nutrients. Many different genera and species of nematodes can be important to crop production in Florida.

Nematode Management in Sweetpotatoes (including Boniatos)

Z. J. Grabau and J. W. Noling

The primary intended audience of this publication is agricultural professionals involved in commercial sweet potato production directly or through advising roles (Extension agents, producers, crop consultants, academics, etc.). The purpose is to guide professionals in improving nematode management in sweet potato production and to give a concise but relatively comprehensive summary of relevant information to understand and manage nematodes in this crop in Florida.

Nematode Management in Cucurbit Crops

Johan Desaeger, Hung X. Bui, and Joseph W. Noling

Plant-parasitic nematodes are small microscopic roundworms that live in the soil and attack the roots of plants. Crop production problems induced by nematodes therefore generally occur as a result of root dysfunction; nematodes reduce rooting volume and the efficiency with which roots forage for and use water and nutrients. Many different genera and species of nematodes can be important to crop production in Florida. In many cases a mixed community of plant-parasitic nematodes is present in a field, rather than having a single species occurring alone. Most cucurbits are extremely susceptible to root nematodes and also are often damaged by sting nematodes; other nematodes occasionally cause some losses.

Nematode Management in Cole Crops

Z. J. Grabau and J. W. Noling

Designed for agricultural professionals, this guide provides insights into managing nematode-induced yield loss in Florida’s cole crops. It includes symptoms identification, diagnostic sample submission, and effective management practices.

Manejo de nematodos en cultivos de col

Z. J. Grabau, J. W. Noling, and R. Sandoval-Ruiz

Los nematodos fitoparásitos son gusanos redondos microscópicos que se alimentan de tejido vegetal. La mayoría de los nematodos parásitos de plantas viven en el suelo y atacan las raíces de las plantas. Esto puede reducir el rendimiento al reducir la función de las raíces y, en consecuencia, el crecimiento de las plantas. Los cultivos de col son plantas seleccionadas de la familia Brassicaceae cuyas hojas o brotes se cosechan. Incluyen repollo, brócoli, coles de Bruselas, coliflor, berza y ??otros. Muchos géneros y especies diferentes de nematodos causan daños en la producción de cultivos de coles en Florida. En muchos casos, una comunidad mixta de nematodos fitoparásitos está presente en un campo, en lugar de una sola especie.
