And Control

Ectomycorrhizal colonization of container-grown Pseudotsugamenziesii (Mirb.) Franco (Douglas-fir) inoculated with Rhizopogonvinicolor A.H. Smith was determined after cold storage and after one growing season on a clearcut on eastern Vancouver Island. Inoculated Douglas-fir seedlings were taller than noninoculated controls when outplanted but, perhaps because of browse damage, no growth differences were found after one field season. Rhizopogonvinicolor colonized all of the inoculated but none of the control seedlings examined after cold storage. Volunteer Thelephoraterrestris Fr. colonized almost half of the control and 10% of the inoculated seedlings before outplanting. After one field season, inoculated and control seedlings were colonized by 15 ectomycorrhizal fungi each, only eight of which were found on both. Rhizopogonvinicolor persisted on the roots of inoculated plants, but was also present in the field soil since the control seedlings also bore these mycorrhizae after one growing season. The relative abundance of T. terrestris decreased from the nursery to the field. The other common ectomycorrhizae in the field included Myceliumradicisatrovirens Melin, Cenococcumgeophilum Fr., and types resembling Tuber and Endogone.

The present study is devoted to determine the content of K, Na, pH of soil samples collected from Mahad tehsil territory. Elements leached from the deposits of the fertilizers have been accumulated in soil, thus constituting to soil pollution index. Focusing this study was carried out to compare out the nutrient contents of barren soil and Rice field soil in Mahad tehsil tertiary, by Flame photometry analysis.

Race 1

The method currently used for determining races of Phytophthora clandestina requires isolation of pure cultures of the pathogen and testing of their pathogenicity on a range of differential cultivars. To date, the pathogen has not been isolated directly from soil and isolation of the pathogen from naturally infected seedlings is laborious. A bioassay involving the planting of differential cultivars in soil samples in small planting trays was developed to identify races of P. clandestina in soil. The specific races of the pathogen in the soil were determined by assessing the disease severity and the extent of sporulation of the pathogen on the roots of the differential cultivars. A more rapid baiting method using cotyledons of differential cultivars in flooded soil samples was also developed to determine the presence of different races in the samples. Both bioassays were used to confirm the presence of race 0 and race 1 in separate paddocks at Rutherglen, northern Victoria, over 4 seasons. The presence in field soil of another root rot pathogen of subterranean clover, Aphanomyces euteiches, was also detected using these techniques.

Abstract A random survey of 467 peanut and cotton fields in 17 counties of Southwest Georgia was conducted to determine the frequency of occurrence and distribution of parasitic nematodes associated with peanuts and cotton. Meloidogyne species were present in 9.7% of the peanut field soil samples, Pratylenchus spp. (primarily brachyurus) in 16.9% and Criconemoides ornatus in 97%. Sixty-nine percent of the root-knot associated with peanuts was M. hapla, 25% was M. arenaria and 6% was a mixture of both. Sting nematodes, Belonolaimus spp., were not found in peanut fields in the survey. In cotton soils, 11.8% of the samples contained Meloidogyne spp., 5.1% Hoplolaimus columbus, and 0.7% Rotylenchulus reniformis.
