Sensitivity of Meloidogyne incognita and Rotylenchulus reniformis to Fluopyram.
Fluopyram is a succinate dehydrogenase inhibitor (SDHI) fungicide that is being evaluated as a seed treatment and in-furrow spray at planting on row crops for management of fungal diseases and its effect on plant-parasitic nematodes. Currently, there are no data on nematode toxicity, nematode recovery, or effects on nematode infection for Meloidogyne incognita or Rotylenchulus reniformis after ...
متن کاملVirulence of Meloidogyne spp. and Induced Resistance in Grape Rootstocks.
Harmony grape rootstock displays resistance to several Meloidogyne spp. but that resistance is not durable in commercial vineyard settings. A 2-year experiment in a microplot setting revealed host specificities of two virulent populations of Meloidogyne arenaria and an avirulent population of Meloidogyne incognita. In a subsequent split-root experiment, the avirulent nematode population was dem...
متن کاملExtraction of Root-associated Meloidogyne incognita and Rotylenchulus reniformis.
A technique based on physical maceration of root tissue was developed to extract vermiform and swollen stages of Meloidogyne incognita and Rotylenchulus reniformis. Experiments conducted on soybean and tomato evaluated the efficiency of method (stir, grind), NaOC1 concentration (0%, 0.5%), and duration (lx, 2x) on extraction of nematodes and eggs from 60-day-old populations. Root-associated pop...
متن کاملResistance to Meloidogyne javanica and Rotylenchulus reniformis in Wild Relatives of Pigeonpea.
Meloidogyne javanica and Rotylenchulus reniformis are important nematode pests of pigeonpea. Greenhouse evaluation of 66 accessions of 25 species of Cajanus, Rhynchosia, and Flemingia for resistance to M. javanica based on number and size of galls, galled area of root, and number of egg masses showed resistance to be available in these wild relatives of pigeonpea. Thirty-five accessions had </=...
متن کاملReactions of Grape Rootstocks to Pratylenchus vulnus and Meloidogyne spp.
Five grape rootstocks were inoculated with 0, 100, 1,000, and 10,000 Pratylenchus vulnus. Dogridge and Saltcreek supported low average total numbers of P. vulnus, 136-705/pot, at 12 months after inoculation. Growth of both rootstocks was not affected. Harmony, Couderc 1613, and Ganzin 1 supported high average total numbers, 6-856 times the inoculum levels. Numbers in Harmony continued to increa...
