I was looking at my allotment the other day.

I have blight resistant potatoes, mildew resistant spinach, all my veg seeds seem to have been bred/selected for vigour, flavour, size, and resistance to pest/disease attack....

I know it's early days, but has there been any research into strains of cannabis which have increased resistance to LSF, budrot, mite attack?

I know it would be a huge undertaking, but looking at how many people have problems with different plant ailments, surely it would be a worthwhile avenue for a large seed producer to consider?

Is it just a case of growing out different strains, exposing them to fungus/virus/pests, and seeing which plants show most resistance, and atttempting to backcross in some way, while managing to retain the genetics with the most vigour, most desirable traits?

Sorry bit stoned, just thinking aloud....

Not sure on the research front..... But out of three phenos of smile I've got , two of them don't seem to get the rust that my
Medicine man and AK REALLY suffer with.... ONe pheno got it once.. but not the past two grows. MY MM gets it every single time.
I'm sure I've seen Arbuscule mention similar with his...

Not sure if thats what you meant though mate...

I would have thought that the tropical strains that grow in humid climates like brazil would at least be more resistant to biotrytus(spelt wrong) and to me that says probably also LSF. Just diagnosed my first case of LSF, was on a plant that had spent a week or two in a horrendously hot and underventilated flowering space, it got baked for a while, moved then developed LSF. I managed to have another strain in there which has recovered fine so who knows.
I think it has a lot to do with the plants immune system being compromised, being kept in situations which don't promote optimum health leaving them weak and vulnerable to the fungus. Perhaps a strain grown in more humid, mouldy climes such as the rainforest would have a stronger anti-mould system built in but TBH i'm pretty much guessing all this...

Good Points stoney and mudkipz....

Sorry to hear about your LSF mudkipz....essence will sort you out, I've just rescued a batch of near dead cuts with it, it's the only thing I've had any success with against LSF....

Yeah Stonehenge, my Toothless Grin got it, but it didn't seem to do them so much harm as the Biddy's Sister, which succumbed very quickly.....I have a Cali-O mum who really suffers bad, it would be a real shame to have to lose her, but if it's just an uphill battle when I've got strains which repond to treatment better, then she'll probably have to go....As you say it's not "research" as such, I'm interested in any anecdotal or more proven info on which strains can fight the LSF best.....

I think, the way my grows seem to go, LSF resistance will have to become a part of my mother selection criteria.....

And yes mudkipz, I agree with you about the weaker and more vulnerable plants getting it worse, I have been getting to grips with a new growing medium, and new nutes, and I was doing a lot of underfeeding in veg, those plants showing N def first were invariably the first to get it......

Banghi haze and nepalese jam from ACE, their congo too. They pass the trait on too when used in a cross.

what about green houses AMS aka anti mold strain?

Good thread guys

I can confirm the following strains can hold it off

Mazar - DP

Ice cool - Sweet seeds

Opium - paradise seeds

My killers have just come down with it

not sure what to add next

hb

bad lsf/blue cheese,had other strains in the room that were fine
never had it before blue cheese and done dozen of strains

Well i've got it just now and it started on one of my killers and spread to some other strains.

The Akorn Aka Snowbud seem to take it pretty bad, some pheno's worse than others right enough and also the killers take it pretty bad on all the pheno's by the looks of it.

The strains the seem very resistant are the Nirvana Citral and Sensi Shive Shanti, there still unaffected just now and there now getting treated with essence anyway so they shouldn't get it.

Also the MK Ultra seem fairly resistant, one pheno which is only one plant has got it a little worse than the others but still not to bad and there is another pheno which there is two of and they dont have it at all but theres what i think is third pheno which appears to be a kind of mixture of the other two pheno's going from the way its grown and its got LSF but only slightly.

All in all its a strange bloody thing is LSF, but the answer is protect your plants so they cant get it in the first place.

I can add that Paradise Seeds Magic Bud CANNOT fight LSF.

Spent a small fortune trying to save them including Essence, Catalyst, Granules and all the bits to use it like water heater, bubbler etc.


Just finished Barneys Farm Phatt Fruity and BB Blue Cheese in the same environment and they thrived all the way. No sign of LSF.

From the experiences of myself and and my homies - seasons are the main variable. Seems to be more LSF spores around in the Autumn. Last Autumn, pretty much everyone I know suffered.

Perhaps coincidence, perhaps not.

Thanks for all the input...

we need to start making a list...
...and checking it twice...

Ive got a Smile pheno thats sat next to another Smile pheno and Hottie which are both riddled with LSF and it hasn't even touched her......So far she's deffo looking like a keeper just need to sample her

When i first developed an LSF outbreak the Mango Haze and Super Silver Haze seemed to be the most resistent with a Sensi Star getting wiped out in a matter of days. Eventually during future grows i saw even the hazes showing symptoms but they didnt ever become overrun with the LSF like any indica strains that grew next to them. Like most here i find regular applications of Essence have solved the problem and made growing a pleasure again.

Think theres a bit of pattern here, the more indica the less resistant

Could be wrong but its looking like that to me, plus in my grow tent just now its my mostly indica strains that are getting hit with it.

Hi guys, been doing a scrog BOTH cheese have LSF but are fighting it slowly with essence, Trainwreck is absolutely fine so far and under the scrog net with them..

so add Trainwreck to the list guys..
an a thumbs down on the cheese...

S.C

Every pheno of Smile I've grown so far (3) has been really resistant to LSF. Also NYCD and Lieu Hanh both resisted it last time

The worst victims were Kush (DP's Master Kush), Blue Cheese and - alas Lot#5 UK Cheese wasn't that resistant but I was able to check the nasty progress of LSF with Essence

Like other peeps have said it affected stressed plants most, in particular heat-stressed plants as far as I could tell. This thread reminds me I should get bubbling and spraying

Essence has been brilliantly effective and I suspect LSF has only kept trying it on cos I havn't used a spreading agent to ensure total coverage

Excellent thread, thanks

Was growing Blueberry and nep-jam down in a cellar last summer/autumn and before I treated them the bleberries got hit hard. The nep-jam didnt get a spot even before treatment.

I've had both Mk Ultra and most recently 2 of my 16 White Russian caught it, my chemdog dd never seems to get it though.

I'm feeling the effects now. I don't think my magic clones are gonna make it - They've had 3 doses of essence now at 5 day intervals

When i was still growing (24hrs ago) i found that some pakistani valley cuttings suffered from it really badly - almost white leaves towards end of flower (got to week 7 and they were budding up well) but leaves were ravaged by it. Its a landrace indica so evans181 may well be onto something. Other unknown plants got it as well but i think they were a indica/sativa mix and was were not as badly affected.

Grown the Opium several times so far and our last crop got highly infected with LSF!!!

PowerPlant from DutchPassion directly next to some heavy infected plants seems very resistant!
Non of four females got infected and some skunk next to it died within two weeks!
Skunk strains own a very low LSF resistants from our experiences over the years:

Skunk#1, Warlock, SuperSkunk and Euforia

Purple Pakistani Chitral S1 is very resistant, too!




We can prove this! Our Purple Wreck (TrainWreck x PurpleUrkel) is very resistant against LSF even next to highly infected plants!

Great topic!
