Pest Control Products for Hops 2017

Hot off the press is the updated list of pest control products registered for use on hops in Ontario for 2017.  The full list can be found by clicking on the link below.  New products this year include the insecticide Coragen, the organic fungicides Sereande Opti and Vegol Crop Oil, and the herbicides Select and Centurion.

This list includes both conventional and organic products.  A list of products that might be acceptable in organic production can be found in Table 4 of the document, however organic growers should always check with their certifying bodies before applying any product.   Additionally, the Ontario Classification for all hops products can be found in the appendices.   New hop growers should be aware that anyone wishing to purchase or apply a product in Class 2 or 3 must be certified by taking the Grower Pesticide Safety Course.

Note that pesticide registrations are always changing – as we become aware of changes in the status of existing or new crops, we will try to update that information on this blog. However, as always, this list does not replace the need for growers to thoroughly read product labels prior to application. For full labels, growers can visit the Pest Management Regulatory Agency’s label database

Products in the tables are grouped by chemical family. Pest control products are grouped into families by mode of action to aid in resistance management. There is always the potential for pest populations to become resistant to pest control products with repeated use. To delay this, avoid constantly applying products from the same chemical family. Instead, alternate between products with different chemical family numbers.
