Laboratory & field studies to test the effect of application parameters and develop strategies to optimize the efficacy of pesticide application.
Droplet evaporation studies using an image analysis based test system to evaluate the effects of formulation, temperature, relative humidity and initial droplet size on the evaporation of pesticide spray droplets.
Quantitative and qualitative assessment of spray deposit using gas chromatographic, fluorometric, colorimetric, microscopic and image analysis techniques.
Pre- and post-registration efficacy assessment of fungicides, herbicides and insecticides using laboratory and field bioassays. Deposit/efficacy studies to evaluate the effectiveness of chemical and biological pesticides in the field.
Studies to investigate the biological interface - the dose transfer and dose acquisition of insecticides.
Formulation and product development - Development and testing of biological pest control products including microencapsulated semiochemicals and pathogenic nematodes for insect pest control.
Development of test kits for monitoring the development of pesticide resistance in insect pests.
Performance evaluations of pesticide application systems, equipment (spray aircraft, terrestrial sprayers) and new spray technology in field crops, horticultural crops and forestry.
Technical support for the aerial application of insecticides (e.g. forest protection programs against defoliating insects such as Spruce Budworm, Gypsy Moth, Forest Tent Caterpillar and the European Pine Shoot Moth) and aerial herbicide application programs in forestry.
Development and validation of field sampling techniques using natural and artificial surfaces to assess on-target and off-target spray deposit, and the transport of pesticides in the form of airborne droplets and vapour.
Spray drift field studies and modeling of spray transport for government regulatory agencies and industrial clients. Management and mitigation of spray drift. Chris Riley has conducted over 200 spray applications to evaluate the effects of application parameters (meteorological conditions, equipment parameters, droplet size and target characteristics) on spray deposit and drift.
Method development and analysis of pesticides and other environmental contaminants in soil, water, plant and animal tissue by gas and liquid chromatography.
Development and implementation of pest management programs for the control of biting flies using biological insecticides.
