Analysis that includes extraction, counts and identification to genus/species of Dagger nematodes (Xiphinema spp.) & needle nematodes (Longidorus spp.) from soil.
Dagger nematode feeding can lead to reduced plant vigour and leaf chlorosis, however it can cause more significant damage as some species can vector viruses such as the Arabis mosaic virus (ArMV) that has a wide host range that includes hops, strawberries, raspberries, sugarbeet and lettuce.
Needle nematodes feeding can cause swelling and galling of the root tip and a general stunting of the root system with some species known to vector several important plant viruses, including Tomato Black Ring Virus (TBRV) and Raspberry ringspot virus (RRSV).
