Commercially introduced just over a year ago, the Touché tomato offers glasshouse growers a superb beefsteak variety, combining an intermediate powdery mildew resistance with the flexibility of grafted or non-grafted growing options. Touché is a vigorous variety, with high yield potential, typically producing large, slightly ribbed fruits of 250-300 grams. This variety has shown the ability to withstand harsh summer conditions in Ontario with a good quality fruit. It has also performed well in dry climates.

Early Season Tips
Especially in the beginning of the crop, it’s important to control the vigor by removing a leaf out from the top of the plant on a weekly base, to make sure that the plant will work on its fruits enough. Throughout the duration of the crop, continue removing a leaf from the top as needed, to keep this crop open, as the leaves can become quite large. If the plant becomes too vegetative, this can lead to decreased fruit size. Also during the early season, the climate should be managed to induce generative growth. Good pre-nights, with an evening temperature drop, will help achieve this.
Powdery Mildew Resistance
Powdery Mildew is one of the most devastating diseases affecting tomato cultivation worldwide.1 A good disease package can go a long way for tomato varieties, and Touché meets the criteria for intermediate resistance to powdery mildew. In the event of an outbreak, early disease detection is crucial.2 Because of its strong vigor, it generally doesn’t require grafting to resistant rootstock. However, for growers using long crop cycles, Touché provides the flexibility of growing well in grafted systems.
For growers who take a grafted approach, rootstocks chosen for high nitrogen acquisition ability may allow for decreased fertilizer application without reducing yields, minimizing environmental nitrate pollution.3 Controlling nitrogen levels is especially important early in the
Artificial Light, Yield and Shelf Life
Touché has experienced encouraging results during preliminary testing under artificial light conditions, which can offer growers a measure of control in unpredictable lighting and temperature conditions. The availability of artificial lighting can also help growers respond rapidly to increased market demand. The variety has higher yield potential when compared to Torero and is known for its high quality fruit retention early in the season. Overall, its shelf life is also quite strong, delivering results that are comparable to other industry leading varieties.
When choosing a grafted approach, growers should select either a Maxifort or DRO138TX rootstock, being certain to pinch the graft. Pinching on the second true leaf is advised. Other factors that would impact the decision to graft include the type of substrate used, and the amount of carbon dioxide per hectare. Regardless of whether or not you choose a grafted or non-grafted approach, Touché can be a top performer.
