Soil Texture Affects Meloidogyne incognita and Thielaviopsis basicola and Their Interaction on Cotton
نویسندگان
چکیده
The root-knot nematode, Meloidogyne incognita, and the soilborne fungus Thielaviopsis basicola, the causal agent of black root-rot, are important plant pathogens of cotton in Arkansas. When M. incognita and T. basicola occur in the same field, greater damage may occur on cotton than when only one of the pathogens is present. Studying the relationship of soil factors on M. incognita Monfort et al. (2007) found cotton yield variability was explained by sand content and M. incognita populations in the cotton field examined. T. basicola populations also are influenced by soil texture. The objective of this research was to examine the influence of soil texture on the reproduction and damage potential of M. incognita and T. basicola and their interaction on cotton.

EFFECT OF TEMPERATURE ON THE INTERACTION BETWEEN BLACK ROOT ROT (Thielaviopsis basicola) AND THE ROOT KNOT NEMATODE (Meloidogyne incognita)
Both the root-knot nematode (Meloidogyne incognita) and the soilborne fungus that causes black root rot of seedling cotton (Thielaviopsis basicola) are widely distributed in cotton field soils in Arkansas. Both of these pathogens are capable of causing significant crop damage and yield loss, primarily through damage to the root systems of infected plants. When root-knot nematode or T. basicola ...
متن کاملChanges in Root Architecture Caused by Meloidogyne incognita and Thielaviopsis basicola and Their Interaction on Cotton
The root system is vital for the cotton plant to absorb nutrients and water from the soil and to anchor the plant. Two important soil-borne pathogens of cotton, Meloidogyne incognita (root-knot nematode), and Thielaviopsis basicola can adversely affect root systems resulting in suppressed growth and less efficient water and nutrient uptake and transport. In fields where these pathogens occur to...

A survey of 100 cotton fields selected randomly in 1995 and 1996 was conducted in the High Plains of Texas to determine the incidence and potential severity of Meloidogyne incognita and Thielaviopsis basicola. Information was obtained from producers for each field on their nematicide application rates and fungicide seed treatments. The percent of squares and bolls set was evaluated for 20 plant...

Field experiments were conducted for control of the southern root-knot nematode (Meloidogyne incognita) and cotton seedling disease fungi (primarily Thielaviopsis basicola) in one naturally infested field during 1999 and 2000 and in three additional fields in 2000. Treatments included: seed-applied fungicides (triadimenol + mefenoxam + thiram and carboxin + PCNB + mefenoxam), cultivars (Paymast...
متن کاملEffects of Cultural Practices and Two Soilborne Pathogens on Root Morphology of Cotton in the Field
In many Arkansas cotton fields, factors such as inefficient tillage operations, extremely dry weather and traffic pressure may result in a compacted soil layer or hardpan. Soil compaction dramatically increases soil strength and can restrict cotton root penetration, leading to suppressed cotton height and lint yield (Taylor and Earl Burnett, 1963). This problem may be exacerbated by soilborne p...
