Field experiments were conducted in 1982 and 1983 to assess interactions between Heterodera glycines and Pratylenchus scribneri on soybean in southern Illinois. Soybean cyst nematode susceptible cultivar Williams 79 and resistant cultivar Fayette were treated or not treated with aldicarb 15G. Initial population densities were 35 H. glycines cysts containing eggs, 100 P. scribneri, 30 Helicotyle...
Field surveys were conducted in three oil palm producing regions of Ghana to determine the frequency, population density and geographical distribution plant parasitic nematodes associated with palm. Palms ranging from 4 12 years surveyed during peak periods two successive cropping seasons 2019 2020. A total 64 soil root samples collected extracted identified them. 716 mixed populations 11 econo...

Effects of live and dead (heat-killed) infective juveniles (IJs) of the entomopathogenic nematode Steinernema carpocapsae on nematodes associated with boxwood Buxus spp. were evaluated in field experiments during 1999 and 2000. Both living and dead IJs of S. carpocapsae were equally effective, causing more than 50% reduction in total populations of plant-parasitic nematodes relative to the cont...

Abstract Plant-parasitic nematodes (PPNs) can cause substantial economic yield losses to many agronomic crops in the United States. A regional-scale survey was completed across 20 counties determine PPNs prevalence Michigan corn and how factors such as soil type, tillage, irrigation, cropping systems influence their distribution. Ten different major genera of were identified fields: Longidorus ...
Sugarcane-associated nematodes (Saccharum spp.) can reduce productivity up to 50%. Through the survey, it was possible identify main that occur in a certain region as tool for designing best management and control strategies. The aim of this study characterize population associated with sugarcane North Central, Pioneiro Northwest mesoregion state Paraná, Brazil, quantify nematode genera crop sp...
