It's been my understanding that TSWV is always present in the soil. What changes year to year are the conditions under which it will emerge. Some years are more favorable for it (very wet spring) while other years aren't. I only grow about a dozen plants & do so on a 3 year rotation. One of the varieties I always grow is Bonnie Brae's Husky Cherry. This cv can be bought at any box store. 2 years ago, when the virus was at it's height, BB Husky Cherry withstood the onslaught, while all my standard tomatoes succumbed. I will always grow at least one of these for that reason alone, plus the fact that the production is very good, & the taste is delicious.
