High tunnels, though relatively new, have gained popularity over the past decade among specialty crop growers who want to extend their growing season. However, these environments can make crops vulnerable to the development of soil-borne diseases that reduce yield. This is particularly true for tomatoes, which are the most commonly grown high tunnel crop and can be highly susceptible to soil pathogens. For most field crops, rotation systems are already in place to combat a build-up of pests and pathogens. In field-grown tomatoes, for example, growers are advised to wait a period of 3 years before replanting tomato in a particular field to break the disease cycle. In high tunnels, rotation systems are more challenging to implement due to space limitations, which results in many growers employing a tomato-on-tomato system from one year to the next. This could be especially problematic for heirloom tomatoes, which are popular high tunnel tomato[Read More…]
