Tylenchulus semipenetrans, also known as the citrus nematode or citrus root nematode, is a species of plant pathogenic nematodes and the causal agent of slow decline of citrus. T. semipenetrans is found in most citrus production areas and diverse soil textures worldwide. Their feeding strategy is semi-endoparasitic and has a very narrow host ...
Tylenchidae is a family of nematodes. They are an important group of soil dwelling species that frequently contributes as much as 30% to the nematode species richness of soil samples. [2] They diverged relatively early on and many species pose little risk to economically important plant species. [2]
Bacillus firmus I-1582 (Bf I-1582) has proven to be an effective nematicide against nematodes such as Rodopholus similis, Xiphinema index, Heterodera sp., Ditylenchus sp., Tylenchulus semipenetrans and Meloidogyne sp. [7] It is approved as a biological-based nematicide against root-knot nematodes in crops by the European Commission. [8]
Nematodes play an astoundingly wide range of ecological roles that scientists are only beginning to understand. Word from the Smokies: Scientist uncovers secret life of soil through study of nematodes
Feeding types of plant-parasitic nematodes This article is an attempt to list all agricultural pest nematodes . Species are sorted in alphabetical order of Latin name.
Nematode-trapping fungi are mostly concentrated in the upper part of the soil, in pastures, leaf litter, mangroves and certain shallow aquatic habitats. They employ techniques such as adhesive hyphal strands, adhesive knobs, adhesive nets formed from hyphal threads, loops of hyphae which tighten round any ensnared nematodes and non-constricting ...

They inhabit the same soil as plant root systems in which they can cause stressing or disease in plants. [1] About 8% of the studied species are parasitic . [ 1 ] Agricultural problems associated with Tylenchorhynchus spp. affect many species such as soybean , tobacco , tea , oat , alfalfa , sweet potato , sorghum , rose , lettuce , grape ...
