Petro-Canada has developed new, environmentally friendly, chemistry that controls plant diseases by inducing the natural resistance in host plants. These products have never been tested on onions or carrots. This project will evaluate these products, alone and in combination, for the control important diseases of onions and carrots. Stemphyllium leaf blight on onion, caused by Stemphyllium vesicarium (Wall.) Simmons, is a new disease of onion in Ontario and Canada. The fungus infects the foliage, reducing the photosynthetic area and yield. Different rates and application timings of the Petro-Canada products will be tested, in combination with new fungicides. Dr. McDonald's lab has research on the detection and forecasting of Stemphyllium on onions, which provides synergy with the efficacy trials.

加拿大石油公司开发了一种新的、环境友好的化学物质，通过诱导寄主植物的自然抗性来控制植物疾病。这些产品从未在洋葱或胡萝卜上进行过测试。本项目将评估这些产品单独使用和组合使用对洋葱和胡萝卜重要病害的防治效果。洋葱茎枯病（茎枯病）西蒙斯病是安大略省和加拿大洋葱的一种新病。真菌感染叶片，减少光合面积和产量。加拿大石油公司的产品将与新的杀菌剂结合，测试不同的速率和应用时间。麦克唐纳博士的实验室研究了洋葱上茎状芽孢杆菌的检测和预测，这与功效试验提供了协同作用。
