Ideas for dealing with leaf septoria

As the outdoor season winds down, I see so many of us had leaf septoria issues, usually causing harvest to be premature. I thought maybe we could gather together in a thread, the approaches that we used that seemed to help. This was the 3rd time out of 5 grows that septoria was a major issue in my outdoor garden. I used a sulfur based spray, that did not contain copper, beginning in early July, and thought I was keeping it at bay, but it came roaring back with a vengeance in early August. Ultimately, strain selection is the best prevention, and I had 2 strains from Lyme Rising Farms that dealt with the septoria really well, and I was able to finish both plants. Those strains were called Bashear and Salvisa. Despite being next to a heavily infested plant, the Salvisa did not get any leaf spotting. I am aware that it could have just been those 2 phenotypes that did well, and other phenos of Bashear and Salvisa may not fare so well. We'll see next year! The pic is of Salvisa.Salvisa.jpg

Had severe Septoria in one garden and less severe in second garden 20 miles away. Have 3 neighbors that also had it bad. Thankfully my first auto grow made it through. Next summer might try plastic between the rows and experiment with weak sprays of hydrogen peroxide, baking soda, or apple cider vinegar. Very happy with the autos although a much smaller yield, and they were done by Labor Day. Just starting to cut the photos now in upstate NY.

Have you grown The Church? Curious as to the results.

I just looked that up, unfamiliar with it until now. I do know Lyme Rising grows outdoors in Michigan, which might mean you could get genetics and info directly from him at a cannabis event.

I was hoping the strain with Erdpurt from OGS would show better resistance but it didn't seem to. Thanks for the tip. I'll check out the site.

December 9th in Muskegon there is a Sungrown Celebration and competition. Lyme Rising is one of the sponsors. I think the thing about PNW genetics is that they are bred for cool, wet weather mold resistance, and my problem is warm air, high dewpoint fungal issues, septoria. But I am all for earlier finishing flowers, outdoors! Less chances of a fall hail storm or anything else hitting the plants. Also, any given pheno could be a dud as well as a rock star, us home growers can't run dozens and hundreds of plants looking for specific traits, we can only run our legal limits and hope to achieve the breeder claims.

Just as the west coast growers searched and bred for genetics that did well in their environment, so too the outdoor growers in the emerging legal states have to do the same. It is just going to take time.

What turns me off about the website is there's no description at all for growers. OGS is not the best site to navigate but there's generally some kind of description of the strain. Correct I can't run hundreds so I'd rather stick with more tried and true than a strain only one breeder has.

Have you tried Frisian Dew?

I have animals and can't travel much, especially in Dec.

Haven't tried Frisian Dew. I have 32 strains from OGS, but have only run about 6. Nick at Lyme Rising doesn't do much interaction with the public as he has been battling Lyme disease and multiple complications for the last few years. But I have grown 5 of his plants outdoors, and they have all been stellar! Nick's Bickett. OG is being used and bred with all over the country. At The Cowboy Cup last year, here in Oklahoma, all the west coast people that I talked to knew and respected Lyme Rising Farms. If we can even just start a simple list of strains and the sources they came from, that did well against septoria, that would be a step in the right direction!

I would like an early finisher that is resistant to septoria and all fungus really. Do you have a best strain that fits the bill?

Appreciate your input!

Can you tell me where you ordered the Salvisa seeds from? Was it the 15 pack of reg seeds?

I have ran it multiple times in the bush back when we were illegal here. Same with the Church both very tough high mold resistance but would not pass muster these days just mids at best. But in the 90s it was considered killer same with Hollins hope an early girl.
