have you ever wondered why you see a sulfur iron deficiency with fungus snaps well in this video
we're going to get into it you're here with mark batwall at perfectgardens.com please remember to
like share and subscribe i'm always grateful to all your support guys if you haven't checked out
our monthly membership i highly recommend to do so just for 2.99 your questions get sent to
the top for quick replies and if you haven't heard i was recently sent a cease and desist
order threatened with the lawsuit if i didn't take down my review against clean cleaner
i'm asking for a little more support to build up my warchest so that i can continue to keep
giving you open and honest reviews and we can further defend our right for free speech thank
you so much everyone first and foremost let's just get into the solution before we get into
all the nitty gritty and the and the nerdy stuff all right so first and foremost i'm gonna give you
a regimen that if you ran into fungus gnats if you did these things your fungus gnats would be
gone fairly quickly and your plants would go back to looking good fairly quickly okay so fixing the
problem first thing i would do if i had smite or banish on the shelf because they are one of our
approved pesticide fungicide brands is i would use it as a root drench here are the essential
oils that work well against fungus gnats and rudra attached three of the four essential oils
in their product if you do not have smite or banish on the shelf i would not wait to order
it obviously if you go down the store and pick it up by wood but if you can't then i would go ahead
and just move on to number two i would put down a small layer of dochinations earth so dochinations
are going to help a couple ways it's going to help give your plants a little bit of calcium
because most likely you're going to be running into fungus gnats earlier in the grow versus later
unless you haven't tried to solve the problem at all and if you haven't tried to solve the problems
then that's probably devastated your crop and you're probably not into flowering at all anyways
so this is going to help you in two ways right it's going to give your plants a little bit of
calcium so that as you're going through veg and as you go into flowering and as the plant
needs calcium you're going to give it a little additional calcium and in addition to that it's
going to be a natural pesticide dochinations earth is microscopic little seashells that will actually
cut up stuff living in the soil i actually forgot one more thing too i put some neem seed down not
oil but neem seed itself and i if i have the opportunity i would have amended my soil with
neem seed or insect flask three what i would also do is i'd put a small layer of beneficial bacteria
of fungi powder preferably or i'd brew up a tea and i'd give a good tea to my plants as
i'm going through this process and i'll explain more why later it would make a lot of sense in a
few minutes fourth i would put down a small half inch a layer of sand obviously if you're in pots
this is how it's going to work if you're outdoors putting sand down might not be the best option
why is sand going to work well is because it drains quickly and dries fast and that's where
the fungus gnats actually lay all their eggs is right on the top layer of the soil fifth i would
put down some yellow sticky traps and then six i would follow your spray with drops of balance
obviously at one ml per gallon drops of balance make sure to ph the water first or i would fully
spray with the fulvic acid because fulvic and humic acids are sulfur based and in a few minutes
it will make more sense why i suggest foliating with db or fulvic acid will help make your plans
come back fairly quickly one additional thing i want to point out to you guys is adults live
for about one week during each time each female deposits about 100 to 150 eggs so just take into
consideration right we're going to be putting on a pesticide that hopefully will eliminate some
bugs immediately second we're going to put down a layer that's going to help kill the remainder
of the bugs that are laying around but you have to take into consideration that in one week a
female can put over 150 eggs down so very quickly a few thousand eggs could have been deposited in
your soil so it will take anywhere from seven to ten days for us to fix the problem as well as the
plants to start to come back and be restored so just kind of keep that in mind just because you
see a few fungus gnats it doesn't mean you don't have a full-blown infestation right underneath
your soil waiting to bloom now let's go ahead and get into the geeky part around the knowledge of
what are fungus gnats and why they cause sulfur iron deficiencies and why you see them together
all the time okay you have your eggs and then you have a three to six day period where it turns
into larvae during this larvae time the larva is actually feeding on a number of different things
from mulch to leaf mold to your root hairs and the beneficial fungi also in the pupil stage and then
as it gets into the short fly and fungus gnat the full-size adults they actually don't eat very
much the only thing they really do eat is going to be water and sap from your plants basically
as this bug goes into different stages it's going to cause different types of plant deficiencies if
you allow the problem to keep going without any type of pesticide control regimen okay so why
is this problem happening right the fungus larvae are eating the fungi and eating the root hairs and
what do the fungi and root hairs do for us right well the root hairs collect the nutrients and
take it up and then the fungi are responsible for the sulfur and iron coenzyme reaction during the
nitrogen fixation process and in past videos i've talked about this already so i'm not going to go
too heavily into it but we're just going to talk about it real fast right so you have a lightning
bolt that come and splits the atmosphere turning into into as it combines with water it turns into
nitric acid as the nitric acid falls down the bacteria is turned to ammonia but before this
ammonia process you need iron sulfur and malignant which i always say that name wrong so i apologize
a few people have already corrected me on that what's interesting though is that the sulfur
and the iron are the fungi responsibilities so if the fungus gnats are eating the fungi
the deficiency is going to show up in a sulfur and iron deficiency this is why these deficiencies
actually look very similar this one's the sulfur right here and this one's an iron as you can see
the deficiency right here on the tips specifically ferrodoxins are the iron sulfur protein and when
you don't have fungi because obviously the fungus gnats are eating it or the larvae specifically
there's not going to be sulfur availability and obviously you're going to be receiving it in a
once again an iron and a sulfur deficiency within the plant so as you can see right here my thought
process around fixing the problem using a rudrant obviously because the eggs are right there at
the top using some dochination's earthiness to cut them up and also to help rebuild the cell
structure because calcium is going to be needed if you use gypsum gypsum is going to be calcium
sulfate i don't believe it has the same types of properties as dochinator's earth i could be wrong
as kind of like the pesticide but you could go ahead and do your own research and make your own
decision the reason why obviously i'm encouraging the calcium is because the plant has been damaged
you need the sulfur for the growth sometimes i've seen leaves get all distorted and kind of missing
sections of the leaf when sulfur is not available and that's my theory that's my own thought process
through me seeing pictures and observation i'm like oh interesting so i'm definitely going to
want to be putting a few minerals a little bit more in abundance for the plants so that
it's gonna have what it needs to recover it as it continues to keep growing putting down a small
layer of bacteria and fungi right because i'm replacing what they're eating the sand right i'm
creating an environment that's difficult for them to grow and flourish the yellow sticky traps is
to just catch the adults that are going to travel to other plants to then lay their eggs in the soil
and create even a further bigger problem i am controlling the infestation and then the foliar
spray obviously because the fungi and roots have kind of been damaged i want to use a foliar spray
to provide the trace minerals that the plants need because once again sulfur and iron are a
semi mobile nutrient so the plant can recover and the minerals can be restored if given thoughtfully
i know in the beginning of the video i threw out a couple other things so also take those
in consideration i just can't really remember what i said i hope this video was helpful please give
me a thumbs up like share and subscribe have a great girl everyone there are two types of
fungi there's a decomposers and then there are the mycorrhizae separatory is a decomposer let's
get real quick into how to solve this problem so first thing remove infected foliage right
