In 2016, many areas of the province saw very warm and dry conditions, creating challenges for horticulture and field crop producers. Many wells were still dry leading into the winter. In other years, like the start of the 2017 growing season, the province experienced periods of excessive rain, leading to saturated soils and flooding.
No one can control the weather, but we can plan for it. The Ministry of Agriculture, Food and Rural Affairs (OMAFRA) encourages you to plan for future weather – conserving water and using it efficiently can help during low water conditions, and having effective drainage systems in place can help with saturated soils and runoff.

It seems like recently there have been a rash of proposed or pending pesticide regulation changes that affect field growers, and tomato growers are no exception. There are re-evaluations ongoing for a number of products used in tomatoes, including mancozeb, neonicotinoids, and Lannate, as well as Ethrel, but the big one that comes to mind for field tomato growers is the proposed changes to the use of chlorothalonil (Bravo, Echo). The final outcome of this review is not yet known, but it’s likely that significant changes to the chlorothalonil labels are coming.
Chlorothalonil is a go-to fungicide for tomato growers. Data from trials at Ridgetown Campus demonstrate its value. Chlorothalonil is often just as good at controlling early blight, Septoria leaf spot, and anthracnose fruit rot as alternative fungicides, and it also provides protection from late blight, which many targeted fungicides do not. It’s a good value active ingredient for tomato disease management and has a low risk of resistance development. But, if proposed changes go through, the number of chlorothalonil applications you can use will be drastically cut.
So, have you thought about how you are going to adapt? Continue reading Making Lemonade Out of Lemons – A Tomato Fungicide Stewardship Tip Amidst Changing Regulations
There is a long list of insects that can damage field pepper fruit in Ontario. Many cause significant damage on their own, but they also provide a means of entry for rot organisms. For more on pepper rots, see Pepper fruit rots.

Not being able to finish a tank due to weather or any other reason happens to just about everyone. Is it OK to simply leave the sprayer as is, and resume spraying later after some agitation? In many cases, the answer is yes. Most pesticide mixtures are stable in short term storage. On resuming spraying, an agitation…

Herbicides are useful tools for the management of weeds. The herbicides registered for use in tomatoes are selective in their activity, injuring or killing weeds while being safe to use on the crop. Crop injury may occur, generally when a crop is stressed beyond its ability to adequately deal with a herbicide application. Injury due to herbicides can arise as a result of several factors, including weather-related stress, soil factors such as light soil texture and low soil organic matter, shallow planting and sensitive crop varieties. The pages in this section contain information on herbicide injury for several products registered on tomatoes in Canada. Continue reading Herbicide injury symptoms in tomatoes
