US22 was detected in tomato plants for sale in garden centers in numerous states by extension specialists. First reports of the pathogen were recorded in late June, the earliest incidence of widespread disease ever observed in our region. This new genotype of late blight, US22, caused a disease epidemic throughout the Northeast. Typically, potato is the main crop affected in 2009, a strain aggressive on tomato was present on tomato transplants. In 2009, the disease was widespread and developed early. Late Blight outbreaks from 2005 to 2008 developed during late summer/early fall and were the result of inoculum (sporangia) carried on storm systems that originated in southern areas where the disease was active. Late Blight caused by the fungus-like organism, Phytophthora infestans, occurs sporadically in most of New England in most growing seasons. It didnвЂ™t affect the fruit and the plants survived but my concern is whether the seed was infected or whether it came from somewhere else.Photos of Late Blight on Tomatoes, Many good close-up photos from the Long Island Horticultural Research and Education Center Throughout the year we had an issue with what I eventually decided was Bacterial Canker (it seemed to give all of the signs of wilt so IвЂ™ve really no idea what it was) however, the first plant to fall foul was the regular leafed Mountain Magic and it gradually spread throughout all the indoor tomatoes. At the end of the season, I had a problem. The Potato Leafed Mountain Magic F2 is the first tomato to start changing colour (2nd July) with a standard sized fruit on the first truss changing and ripe (ready to pick I think) on the 7th July). The potato leafed version has been one of the first to set fruit (27th May) so, it will be interesting to see how it compares to other early cultivars. IвЂ™m growing them both in the greenhouse to compare one against the other. Again IвЂ™ve ended up with a regular leafed version and a potato leafed version.

To be honest, in our experience, the вЂњBlight ResistantвЂќ cultivars are not worth it (as yet) and, as blight is basically carried on the wind and damp, our best advice if you have blight in your area, is to grow tomatoes indoors as far away from potatoes as possible and then to carry out all blight prevention measures which include: Keeping the doors and windows closed as much as possible visiting your tomatoes before you do anything else separating anything you use in the greenhouse (secateurs for example) from those used outside trusting to luck.Дў020 Update: IвЂ™ve tried again to grow the F2 from Mountain Magic.

Its still difficult to work out what the parents of Mountain Magic are (and therefore which has what sort of blight resistance). Looking in more detail at the parentage from these links: The assumption is that these represent the parent tomatoes in some way. A potato leafed variety and a regular leafed variety. However, this is probably unfair as the comparative fruit were all ripened on the vine and the Crimson Crush/Mountain Magic were ripened off the vine which probably doesnвЂ™t allow them to properly develop their flavour.Дў017 Update: As well as growing the F1 seeds left over from 2016, we also sowed some F2 seeds collected from the allotment plants in 2016. By late November about 80% of the fruit had ripened. We sorted out the fruit that looked like they were infected with blight (about 20% of the Crimson Crush fruit but none of the Mountain Magic) and brought them back to ripen indoors.

Neither Crimson Crush nor Mountain Magic produced any ripe fruit before we were forced to pick the green crop in late October when frosts were becoming a threat. All of the Heritage varieties failed to late blight quite early but both Crimson Crush and Mountain Magic, whilst they had blight on some fruit, carried on growing through the blight and produced a crop. In 2016, we grew Crimson Crush, Mountain Magic and a few heritage varieties. Late Blight is endemic at our allotment site and any tomatoes grown outdoors for the last 10 years (in 2016) have usually suffered from late blight (it seems a little strange that we would keep trying tomatoes, but there have been a couple or three years when we have not had blight and that kept us trying. We have grown Mountain Magic in 2016 as part of our attempt to grow tomatoes at our allotment outside. It is a вЂњlarge cherryвЂќ (about 1 вЂ“ 1.5 inches) and crops well. Developed by North Carolina State University it has resistance to both Early and Late Blight.

Mountain Magic is a вЂњBlight ResistantвЂќ F1 Hybrid. A large cherry, blight resistant red F1 Hybrid tomato on indeterminate plants.
