Variability among Populations of Meloidogyne arenaria.
Variability in reproduction and pathogenicity of 12 populations of Meloidogyne arenaria race 1 was evaluated on Florunner peanut, Centennial soybean, Rutgers tomato, G70, K326, and Mc944 tobacco, and Carolina Cayenne, Mississippi Nemaheart, and Santanka pepper. Differences among M. arenaria populations in rates of egg production 45 days after inoculation were observed for all cultivars except S...
متن کاملResistance to Meloidogyne arenaria in Arachis spp. Germplasm.
Field and greenhouse evaluations of 116 wild Arachis spp. genotypes demonstrated the presence of resistance to reproduction of the root-knot nematode Meloidogyne arenaria race 1. Resistance in greenhouse tests was based on test lines having </= 2.5% of the number of eggs per gram of roots as did the susceptible A. hypogaea cv. Tamnut 74. In field tests, resistant genotypes were identified on th...
متن کاملSoybean Response to Two Isolates of Meloidogyne arenaria.
Meloidogyne arenaria (Neal) Chitwood and M. incognita (Kofoid and White) Chitwood, prevalent in the sandy soils o f the southeastern United States, can severely limit soybean, Glycine max (L.) Merr., yield (10,12). Meloidogyne arenaria populations have increased in some southeastern states in recent years, apparently due to increased plantings of the soybean cultivar 'Centennial', which is resi...
متن کاملRate, placement and timing of aldicarb applications to control Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), in oranges.
BACKGROUND The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is a cosmopolitan insect pest of citrus and vectors the bacterium Candidatus Liberibacter asiaticus, a suspected causal organism of citrus greening or 'huanglongbing' disease. Aldicarb 150 g kg(-1) GR (Temik((R)) 15 G) was evaluated at three rates, two placements and three timings for ACP control in ora...
متن کاملDamage Functions for Meloidogyne arenaria on Peanut.
Microplot experiments were conducted in 1989 and 1990 to determine the relationship between yield of peanut (Arachis hypogaea) and inoculum density ofMeloidogyne arenaria race 1. Nine inoculum densities were used, ranging from 0-200 eggs/100 cm(3) soil (1989) or from 0-100 eggs/100 cm(3) (1990), and each density was replicated 10 times. In 1989, higher final densities (mean of 1,171 juveniles [...
