Abstract Root-knot nematodes ( Meloidogyne spp.) cause serious damages on most crops. Here, we report a high-quality genome sequence of exigua (population Mex1, Costa Rica), major pathogen coffee. Its mitogenome (20,974 bp) was first assembled and annotated. The nuclear then constructed consisting 206 contigs, with an N50 length 1.89 Mb total assembly 42.1 Mb.

The present study explored the efficacy of Bacillus spp. and protease production for biocontrol of the root-knot nematode Meloidogyne javanica in African violet media. Among 100 bacterial isolates from various soils, the highest nematode mortality was observed for treatments with isolate GM-18, which was identified as Bacillus subtilis based on cultural and morphological characteristics and 16S...

1,3-Dichloropropene (1,3-D) and nonfumigant nematicides were evaluated for control of Meloidogyne spp. and soil and foliar insects in a tobacco pest management system. In a field with a high Meloidogyne spp. population density (root gall index 4.0 to 4.5 on a 0 to 10 scale in untreated controls), tobacco yields and crop values increased (482 kg/ha and $1,784/ha for 1, 3-D; 326 kg/ha and $1,206/...

Eight commercial pea fields on Prince Edward Island were sampled in June and July over a 2-year period (1986-87) to determine soil population densities and the incidence of nematodes and fungi associated with root rot of peas. Root lesion nematodes (Pratylenchus spp.) were the dominant endoparasitic nematodes recovered from roots and soil. Low populations of the northern root-knot nematode (Mel...

The tomato gene Mi-1 confers resistance to root-knot nematodes (Meloidogyne spp.), potato aphid, and whitefly. Using genetic screens, we have isolated a mutant, rme1 (resistance to Meloidogyne spp.), compromised in resistance to M. javanica and potato aphid. Here, we show that the rme1 mutant is also compromised in resistance to M. incognita, M. arenaria, and whitefly. In addition, using an Agr...

Bu çalışmada kök-ur nematodlarının Batı Karadeniz Bölgesi kivi bahçelerindeki yaygınlık ve yoğunluklarının belirlenmesi amaçlanmıştır. amaçla 2015 2016 yıllarında Düzce (2), Zonguldak (3) Bartın illerinde sekiz bahçesinden kök toprak örnekleri alınmıştır. DNA ikinci dönem larvalardan ekstrakte edilmiş, ClearDetections firmasına ait M. tropical spp., hapla enterelobii real-time primerleri Meloid...
