As growers are continuously battling new pests, as well as old nemeses, any new tool is a welcome addition in the pesticide toolbox.
The Pest Management Regulatory Agency recently registered an interesting new product: Magister SC (fenazaquin), which is a miticide, insecticide AND a fungicide!
Although registered against powdery mildew in some crops, only the miticide/insecticide use pattern is allowed in greenhouse ornamentals. More information on this product is available below.
