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 ...
There are numerous reports of nematicidal chemicals in crude plant homogenates, leachates, and decomposing residues. These compounds are usually assumed to be secondary metabolites, which serve as chemical defenses against disease and parasites. When such compounds are released into the rhizosphere, they are known as allelochemicals. The possibility exists to exploit allelochemicals for nematod...
A population of Xiphinema insigne with several males was found on the campus of Zhejiang University, Hangzhou, China, in November 1998 in the rhizosphere of Yulan Magnolia. Morphometrics of nine males and 25 females of this population are given herein. No sperm were found in the genital tracts of 118 females that were examined. This agrees with all other observations reported for this species e...
Nematode occurrence at specific locations throughout a water catchment-irrigation system was determined. Soil samples were collected from five water source locations on the slopes of Olomana Mountain and Maunawili Valley and from about 40 plant species on 18 farms (56 ha of 480 ha irrigated by the reservoir). Water was sampled from the catchment reservoir at 0.3 m, 9 m, and 18 m (bottom). A far...
