Stunt roots, transmit Tobraviruses including Tobacco Rattle Virus, Pea early-browning Virus and Pepper Ringspot Virus.
Tobraviruses are straight tubular particles with two size ranges, 180-210 nm and 45-115 nm. Trichodorus and Paratrichodorus are vectors.
At root tip.
Nematodes in the Trichodoridae have a wide host range.
For an extensive list of host plant species and their susceptibility to this genus, copy the genus name
select Nemabase Genus Search and paste the name in the Genus box
Root tip damage causes root elongation to cease. Hence "stubby root" symptoms.
