Hi folks it's been a while since I was on these boards I hope this question is in the right place: What strain have you found to be most resistant to leaf spot fungal disease? thanks in advance for any replies given.

[Wretchy]

Out of interest, why do you want one that is particularly resistant to LSF?

[bigbadbudboi]

Iv found 4 plants iv grown this time are particularly resistant to lsf and was thinking of starting a thread to see if other people had found strains resistant to it. I found that Sleestack and Connie Chung from DNA, Power Kush from Dinafem and Wild Rose from Sweet seeds have barely been touched by it. The strains worst hit were S.A.D, Cream Caramel and Confidential Cheese. Iv kept clones of everything so im gonna look to keep running the lsf resistant strains because i cant seem to get rid of the lsf

Get some essence and grow whatever strain you want.

Problem solved.

thanks for the replies: Wretchy to answer your Q, I like my growing to be as low maintenance as poss. I like others can't seem to shake the lsf, I have used essence before which has allowed a crop but it is a pain to prepare and administer hence the enquiry about resistant strains.

yes but it does not work all the time and certainly not against a bad case of l.s.f as i suffer bad problems with it.

Useful thread because I've been hit by it in the past and some strains cope more better than others, for begginers or those hit badly by LSF could do with working with a hardy strain to begin with.

I also agree that Essance is a right twat to brew and time accordingly with lights out but it does do the job. Also waste a lot when you only have young plants to spray. I used to resort to spraying with Neem oil to put a protective layer between the leaf and the fungus and then when they more mature and worth brewing up a few litres of essance I'd then spray with that. Dont get me wrong it's not the best way forward but it's difficult to brew small amounts.

I find the best protection against LSF is to make sure you have good air circulation in the room, have healthy plants that arn't overfed nitrogen (dark greed) as it produces week sappy growth that's suseptable to attack.

Best of luck for the future mate, I know how horrible it can be to get attacked by the fungus!

P.S. Sorry can't help with strains as I aint been hit (touch wood) with LSF for a while

I have a C3 pheno that is resistant to white powdery mildew - might be worth a pop, but its just that one pheno, so I don't know if that is any use to you?

Smile just looks at LSF and laughs it off twice I've known it surrounded by infected plants and she just grew on, indifferent

[Artificial Emotion]

Wish I knew, it's been the bane of my life since November last year. I've managed to overcome it by using essence regularly - at least every third day. If you can keep on top of spraying with essence, particularly before the LSF infects your plants, you'll be fine whatever strain you're running. Spraying with essence is a pain in the arse but it's not that bad really.

I'll have to try smile because I've heard fairly good reports about that strain anyway.

Its funny you say that cos i found with smile that the more indica shorter faster finishing pheno didn't get touched by it but i had a 12wk pheno that got hit hard with it! Iv got some nonames about to go in which i hope will show resistance because they're such vigorous growers and seemed pretty bullet proof in my mates first grow in compost and associated issues!

[benbits]

Thanks again for the replies. Smile seems like the best bet thus far, I'll give that a go next time round. I have also improved my ventilation, yet again

That. Smile is just incredible, it outperforms every other plant put next to it by a length.

[distracted]

If you get it repeatably then are your sterilising your room and equipment after an infected grow?

In commercial hemp operations yellow leaf spot fungus is thought to be linked to humidity under the canopy of the plants and good air circulation is considered preventative against infection.... in an indoor environment we can resist overcrowding our plants, add a good amount of air movement through the plants using a moving desktop fan to even out the humidity under the canopy and if needed we can trim unwanted growth

ETA I read somewhere once that the strains that had evolved in dry arid conditions such as afghan plants where more susceptible to fungal infections such as budrot in a humid growroom

^ I read a quote by OT1 that said that a good environment in the grow room doesn't prevent LSF (don't know about fields of hemp). Whether this is definitely the case, I don't know. As for my LSF which keeps coming back, I think the spores are everywhere, making it a never ending battle. The only way to control it I've found in my personal experience is with essence, and as long as I keep on top of spraying it works really well.

If I could find an LSF resistant strain I would be over the moon.
