I've been hit with powdery mildew help..

**FLoJo** · 12-29-2009, 02:03 PM

milk, greencure, h202, potassium bicarbonate, baking soda spray, all this shit is just a bandaid!!

PM is a systemic fungus, which will NEVER go away unless you fix it.. all it needs is a few hours of proper conditions, and you have another problem.

Meltatox is a systemic fungicide that is proven to work, Eagle EW20 is a fungicide which is proven to prevent PM on dogwood trees OUTSIDE, in optimal breeding conditions.. i have no doubt it will work for indoor eradication.

sulphur burners are the only other practical way of controlling PM since they create a fine fog which will coat ALL surfaces in your grow room and prevent the propogation of PM. sprays and all that shit will work, but you have to hit EVERY spore in the room, every leaf, every nook and cranny, EVERYWHERE otherwise within a few days you will see it again.

sulphur burners coat the entire room, and destroy every living spore in its radius, as well as prevent the hyphae from colonizing the leaf surfaces.

i believe that a combo of systemic fungucides and sulpher burning can eradicate pm completely.. i will know in a couple weeks and will keep yall updated..

oh ya and got the eagle ew20 at tampa agricultural products google tampa ag... i think you can also get it at rosemania.. it stays in the plant for 30 days so i wouldnt spray it past a week or 2 in flower

Powdery Mildew (PM) is a systemic problem coming from within an infected plant. What you are seeing (the white powderey looking substance) on the leaves is the flowering body of the fungus- the hyphae live within the plant. By the time you can visually identify the problem it's already well established within the plant. No external treatment (like sulphur) can fix the problem.

PM proliferates in shaded and low-light areas of gardens where the humidity is raised; obviously countering these grow room conditions will slow the spread but it won't truly eliminate the fugus from the plants.

The same is true for sulphur applications; be it from a sulphur burner or from a solution such as Safer's Defender. Sulphur will prevent the growth of PM where it is present on the leaf, but the PM still exists within the plant.... not to mention sulphur applications negatively affect the taste of the final product; it seems to concentrate on the resins and an experienced or trained palate will always be able to tell if there was sulphur applied to the plants from how the hash smokes. I recommend using sulphur on vegging plants NOT flowering plants

.
Sulphur inhibits the growth on a cellular level by interfering with biological processes opf the fungus this is also well documented on the scientific literature.

A higher pH spray does help to slow the fungal growth, but this is not the reason sulphur and potassium bicarbonate are used to combat PM.

yes i will agree that a sulphur burner by itself is a bandaid, however it is still the most effective method of prevention.

a single spore can sit in your carpet, on a wall, or on a fan blade, and propogate a whole room, even if you spray down every single plant..

a sulphur burner on the other hand, will fill every single nook and cranny with sulphur, and kill all spores in the area. the REASON that a sulphur burner is not a cure all is because it can only kill the spores, however it cannot kill off the actual fungus that resides inside of the plant. this means that when conditions become favorable it will reproduce again...

that is why if you use a burner, to kill and steralize everything, and then a systemic fungus to actually attack the fungus itself (and not the hyphae) complete control can be achieved...

if you just use the fungicide by itself, spores can remain in your room, and after the 14-30 day life of the fungicide wears away, the remaining spores can reproduce and you will have a vicious cycle on your hands..

PM can be eradicated, but several means of attack must be used in order to kill what is inside the plant, and outside the plant.. i will keep yall updated on my progress.... seen a friend battle it now for 3 grows and its time to annihilate this shit

I love the smell of Rotten Eggs in the morning...it smells like my neighbor is using his sulfur vape again

Gotta lower your humidity,you should also get a dehumidifier.Grow mildew resistant strains next time.

I use a dehumidifier ...I got 30% RH and still get it.. that may help keep it to a minimum

3weeks into flower with pm greencure otw its been ten days since the sulphur spray i see no visable signs of the mildew theres alot of new growth at the bud sites and id hate to cover all that green in sulphur should i reaply the sulphur spray then a week later use the greencure for the last month or should i wait till it gets here and just use greencure till the end also should I wash the sulphur off with high Ph water or should I leave the sulphur on?
Thanks again for your help.

im 4 weeks into flowering and just starting to see a bit ona few leaves show up again. my question is if i use milk or greencure will i have issues when im drying and curing the bud after harvest. and if there is a bit of mold in the bud and i smoke it is that bad? if the bud is caked in mold id throw it out but i doubt it will get that far...
