Trace Element & Nutrient Retention and Release from Ontario Greenhouse Retention Ponds

Tributaries adjacent to greenhouse operations in Leamington, Ontario were found in 2012 to have elevated levels of phosphorus. The objective of this research is to identify the source of elevated nutrients in greenhouse ponds by collecting water and sediment samples over the course of 2 years. These samples will be analyzed to find linkages between nutrients found within the ponds and the surrounding environment.

Improved pest management: diagnostics for management of pesticide resistance in greenhouse populations of the two-spotted spider mite, aphids, whiteflies and thrips

Mite and insect pests pose an ongoing threat to the sustainability of greenhouse vegetable production. Their control is critically reliant on pesticides. However, the intensive use of pesticides and the shrinking number of registered insecticides and acaricides increases the selection pressure against the few chemicals available and accelerates the evolution of resistance. This is critical for the two-spotted spider mite, aphid, whitefly and thrips populations as they are becoming increasingly difficult to control.

International Farm Workers in Essex County: Belonging and Socially Inclusive Rural Communities

While agricultural migrant workers provide much needed labour in Canadian agriculture, they feel alienated from the host society. Their alienation and exclusion is related in part to the working and living conditions migrants experience in Canada.

Develop integrated management of bacterial canker disease for greenhouse tomato

Greenhouse industry is an important agricultural sector in Canada. Approximately half of the Canadian vegetables is produced in commercial greenhouses. Ontario greenhouse industry contributes to 40% of greenhouse production in Canada. As one of the most important greenhouse crops, tomato production is threatened by canker disease leading to significant loss for growers. Tomato canker disease is caused by Clavibacter michiganensis subsp. michiganensis (Cmm), a Gram-positive bacterium. This is a very difficult plant disease to eradicate or manage. In this proposal, the academic supervisor Dr.
