Use of Pesticides in Finnish Forest Nurseries in 1996
In 1996 a questionnaire on seedling production and use of pesticides was sent to 33 forest nurseries in Finland. Twenty-eight nurseries answered the questionnaire; thus the survey covered about 80% of the Finnish production of forest seedlings. According to this study, the Finnish nurseries together are using about 1000 kilograms of pesticides (as active ingredient, a.i.) annually. The most use...
متن کاملPhytophthora ×stagnum nothosp. nov., a New Hybrid from Irrigation Reservoirs at Ornamental Plant Nurseries in Virginia
A novel Phytophthora species was frequently recovered from irrigation reservoirs at several ornamental plant production facilities in eastern Virginia. Initial sequencing of the internal transcribed spacer (ITS) region of this species generated unreadable sequences due to continual polymorphic positions. Cloning and sequencing the ITS region as well as sequencing the mitochondrially encoded cyt...
متن کاملGenotyping Phytophthora ramorum Isolates From Nurseries in the United States Using PCR- RFLP and Microsatellite Analyses
The risk of introducing the important plant pathogen Phytophthora ramorum outside of its present natural range is of extreme concern; however, the detection of P. ramorum in U.S. nurseries is increasing. The USDA has confirmed the presence of P. ramorum in nurseries in 21 states that received plants from an infested, southern California nursery and others. This nursery produces approximately 15...
متن کاملPopulation Genetic Analysis Infers Migration Pathways of Phytophthora ramorum in US Nurseries
Recently introduced, exotic plant pathogens may exhibit low genetic diversity and be limited to clonal reproduction. However, rapidly mutating molecular markers such as microsatellites can reveal genetic variation within these populations and be used to model putative migration patterns. Phytophthora ramorum is the exotic pathogen, discovered in the late 1990s, that is responsible for sudden oa...
