Measuring IPM Impacts in California and Arizona
Integrated pest management (IPM) is a method of reducing economic, human health, and environmental risks from pests and pest management strategies. There are questions about the long-term success of IPM programs in relation to continued use of pesticides in agriculture. Total pounds of pesticides applied is a mis-measure of the impact of IPM in agriculture. A more complete measurement of the lo...
متن کاملNitrate and potassium uptake by greenhouse roses (Rosa hybrida) along successive flower-cut cycles: a model and its calibration
Rose (Rosa hybrida L.) plants grown for cut-flower production in greenhouses produce flowers in flushes year-round. Crop models for this system must handle the cyclical nature of productivity, which is determined by the horticultural production methods. Nutrition was not accounted for in previous rose growth models, since little is known about uptake of the essential nutrients by rose roots. Th...
متن کاملSpecific Mapping of Disease Resistance Genes in Tetraploid Cut Roses
Control of fungal diseases is a major constraint of cut-rose cultivation in greenhouses and in transportation around the world. Therefore, development of resistant cultivars is a promising way to reduce the use of chemicals required for controlling the diseases. Genetic analyses and breeding for resistance, however, are hampered by the high degree of heterozygosity and the polyploid nature of c...
متن کاملModeling Diurnal Variation of Whole-plant Photosynthesis of Greenhouse Roses
Whole-plant photosynthetic rate of rose (cv. Kardinal) was measured with an open system consisting of a computer-controlled data acquisition system and an infrared gas analyzer (IRGA). The system was used to monitor diurnal patterns of whole-plant gas exchange in response to environmental variables and a model to simulate this was constructed. A model for leaf photosynthesis was calibrated and ...
متن کاملThe Systemwide Tropical Whitefly IPM Program
CIAT has the responsibility to coordinate the Systemwide Tropical Whitefly IPM Program (SPIPMTWFP), and its various sub-projects in the Americas (described as activities in this section of the annual report), Southeast Asia and subSaharan Africa. These projects are funded by different donors, namely: The United Kingdom Department for International Development (DFID); the United States (USAID) a...
