Abstract:

Greenhouse experiments showed that yellow nutsedge shoot number and shoot and root dry weights were reduced by root-knot nematodes and chile peppers. Root-knot nematodes increased and chile peppers decreased the number of yellow nutsedge tubers. Yellow nutsedge tuber germination was reduced by chile peppers but not by root-knot nematodes. Yellow nutsedge established from root-knot nematode-infected tubers produced more tubers than noninfected tubers. Root-knot nematode populations became established on yellow nutsedge root systems when plants were established from tubers previously cultured wi

Abstract:

Root-knot nematodes (Meloidogyne spp.) are soil-borne pathogens that can cause severe damage to agricultural production. The most common approaches to prevent root-knot nematode infections are based on crop rotation with non-host plants, use of chemical insecticides, biological control methods, and use of nematode-antagonistic or trap plants. Marigolds (Tagetes erecta) are used as nematode-killing plants, but there is controversy over the mechanism through which they control root-knot nematodes. This study confirmed that marigold root-exudates are lethal to root-knot nematodes, illustrated tha

Abstract:

Greenhouse studies in 1995 and 1996 examined the response of yellow and purple nutsedge to inoculation with increasing densities of southern root-knot nematodes. Yellow and purple nutsedge root and shoot weight, numbers of leaves and tubers produced, and tuber weight were unaffected across 17 nematode inoculum densities that ranged from 0 to 20,000 eggs per 15-cm pot, four times the maximum nematode density recorded under field conditions in New Mexico. Hence, yellow and purple nutsedge do not exhibit a classic threshold response to root-knot nematodes. Moreover, the results suggest that the r

Yellow and purple nutsedge and southern root-knot nematode are common pests in intensively managed chile pepper production.

Competition from purple nutsedge or either nutsedge species plus nematodes reduced chile pepper top weight more than yellow nutsedge or nematodes alone. Al

S. spontaneum lines were tested twice for resistance to root-lesion nematode and three times for root-knot nematode.

Root-knot nematodes (Meloidogyne spp.) are major pests of pepper (Capsicum spp.) in the United States, and parasitism of susceptible plants can result in severe yield losses.

Habanero-type cultivars belonging to the species C. chinense are becoming increasingly popular. Unfortunately, all commercial Habanero-type cultivars are susceptible to root-knot nematodes. In 1997, the USDA released three C. chinense germplasm lines that exhibit high levels of resistance to root-knot nematode

Damage to sugarcane caused by root-knot nematode (Meloidogyne spp.) is well documented in infertile coarse-textured soils, but crop losses have never been assessed in the fine-textured soils on which more than 95% of Australia’s sugarcane is grown. The impact of nematodes in these more fertile soils was assessed by repeatedly applying nematicides (aldicarb and fenamiphos) to plant and ratoon crops in 16 fields, and measuring their effects on nematode populations, sugarcane growth and yield. In untreated plant crops, mid-season population densities of lesion nematode (Pratylenchus zeae), root-k

Abstract:

Weeds can act as reservoir hosts of a range of pests and diseases. Information and knowledge on the host status of weeds to common pests and diseases can be used to develop integrated weed and pest management strategies. As part of a survey on the distribution and diversity of root-knot nematodes on crops in Fiji, the root-knot nematode host status of weeds was also studied. Weeds growing in root-knot nematode infested farms (n= 189) and bioassay pot soil samples (n= 277) were identified, and their host status was determined on the basis of a root gall and egg-mass index scale from 0 to 5.

Seedlings of 19 maple (Acei) species, representing 11 of the 23 botanical sections recognized in the genus, were inoculated with the common root-knot nematodes Meloidogyne arenaria (two races), M. hapla, M. incognita and M. javanica, and 10 species with M. querciana, the oak rootknot nematode. Some major landscape species, such as A saccharum and A. pseudoplatanus, were tolerant or resistant to all nematodes. Most of the other widely grown maples were susceptible to at least one of the common nematodes. Susceptibility to M. hapla appeared to be related to the sectional classification of maples

The changes in agricultural situations have tremendous effects on the emergence of new plant parasitic nematode problems in India. Nematodes can parasitize plants, animals, insects, etc. Plant parasitic nematodes are capable of causing disease on many economically important crops grown in India and attained the status of pests for substantial reduction of crop yield but root-knot nematodes is the most damaging one. The most predominant species of root-knot nematodes are <em>Meloidogyne incognita,</em> <em>M. javanica</em> and <em>M. graminicola.</em>

Root-knot and cyst nematodes are obligate plant parasites that induce complex biotrophic feeding structures in host roots. The mechanisms by which nematodes regulate host gene expression to produce feeding sites are unknown. The cauliflower mosaic virus (CaMV) 35S promoter has been reported to be repressed strongly in the feeding sites of both root-knot and cyst nematodes. In contrast, other work has indicated that this promoter is partially active in some feeding sites. Considering the importance of the 35S promoter in biotechnology, we have defined the nematoderesponsive nature of this promo
