In my hands I have a bottle of Organocide by Organic Laboratories Inc. It is 5% sesame oil, 92% fish oil, and 3% lecithin. It kills mites, scale, thrips, etc. It SAYS it controls black spot and other soilborne fungal pathogens. I did not use it this year for disease control. I used it for insect control on my autos, but will take the fungal protection. I used Serenade exclusively for blight/black spot on tomatoes which are by far the most susceptible plants. Considering the conditions( we have had 45 days of above average temps and sky high humidity), and the fact that last year I was crushed by blight, I truly believe Serenade has helped a lot. If you start early and get the herd established maybe you would not have to reapply as often as recommended.

This isn't necessarily on-topic, but I've never heard of using gnatrol (B. thurigiensis israeliensis) for caterpillar problems. This bacteria targets dipterans (true flies such as mosquitoes or fungus gnats) rather than lepidopterans (moths and butterflies). As far as I've read Bt is extremely specific in their control of insect populations. The endotoxins released by each subspecies of Bt binds to certain receptors in the digestive systems of the insect.

1. Insect eats Bt crystals and spores.

2. The toxin binds to specific receptors in the gut and the insects stops eating.

3. The crystals cause the gut wall to break down, allowing spores and normal gut bacteria to enter the body.

4. The insect dies as spores and gut bacteria proliferate in the body.

Bt action

Bt action is very specific. Different strains of Bt are specific to different receptors in insect gut wall. Bt toxicity depends on recognizing receptors, damage to the gut by the toxin occurs upon binding to a receptor. Each insect species possesses different types of receptors that will match only certain toxin proteins, like a lock to a key.

It is because of this that farmers have to be careful to match the target pest species with a particular Bt toxin protein which is specific for that insect. This also helps the benifical insects because they will usually not be harmed by that particular strain of Bt.

From this FAQ site on Bt released by the University of San Diego.

My bad straintester, I'm not meaning pick you apart. I hope it didn't seem that way. I honestly apologize if you felt personally targeted.

Alot of the vegetation near my grow looks bad this year. Its dying off sooner and I see spots on the leaf.

A couple of my clones on the edge of my grow are starting to show spots too.

Ive sprayed all my plants with greencure twice over the last two weeks so I think its giving them some protection.

Tonight I will double up with a spray of Bacillus subtilis for the underside of the leaf.

It is most effective when applied as a preventative BEFORE sysmptoms appear.

B. substilis fungicides are considered totally safe to humans and animals since the bacteria attack only fungi.
It is easy to use and quite effective.

correction:

Leaf septoria use bacillus pumilis, cinnamon oil, clove oil, compost tea, copper, corriander oil, humidity control, pH up, potassium bicarbonate, sesame oil, sodium bicarbonate, sulfur, trichoderma

and for caterpillars use bacillus thuringiensis
commercial brands include dipel, javelin, thuricide, vectobac teknar xantari and gnatrol

this claims it has low toxicity to humans since most is destroyed by sunlight.

i'll have to read up more on this
correction: page on page 92 of garden saver
since it is a fungus, it is a good idea to find a new area to grow in each year if possible and burn all infected leaves
The garden saver book is like abible to outdoor growers

THANKS patti for helping identify the problem
Got the rest fugured out now

No problem, I only consider it hijacking if it is way off topic all info mine or otherwise should be considered suspect until you do some research yourself. I think it's ok to question the info that anyone or I presents you have to do some due diligence. As long as it’s done respectfully.

For me it wasn’t that this particular leaf spot only hits roses its about finding info about the “Leaf Spot” disease in general and I am only guessing that many of the leaf spot varieties have this “life cycle” in common. As a Guerilla its darn near impossible to say how many types of leaf spot we are talking about here.

To practice what your preach as they say, oh and by the way I hope to get more guerillas involved so I am trying to keep the thread hot (looked at) here.

Anyways the reason I am using “Black Spot” or actually any other leaf spot disease info I can find is because;
1. I don’t know which leaf spot if not many I am seeing.
2. Because of #1 we need some type of control with a broad range of disease treatment.
3. In doing my research leaf spot except for maybe tomato blight is considered a mostly “aesthetic value” type of problem I only wish.
4. Because of #3 you will find more specifc info on this diease as it effects flowers like roses because they are sold based on aesthetic value.

Thanks for everyones input.

Mine that are bad are in a flat pine forest with wild ferns all around.i started looking around yesterday at another spot a good distance away from the bad one where i had one clone and it had a mild case of the same thing on the bottom leaves.I started looking at the plants around it and the briars were covered in this damn stuff whatever it is and the more I looked the more i saw it everywhere and the ground covered with dead leaf matter.i don't know where this came from but it is some bad shit!
