Neem oil is a vegetable oil extracted from
the Miracle Tree thats the Neem Tree.
The botanical name of neem tree is Azadirachta
indica.
Azadirachtin and Nimbin found in neem oil
are the two major compounds responsible for
its antibacterial and antifungal actions.
This neem tree is native to the Indian subcontinent
and can be easily grown at home gardening
level even in large containers.
You can watch a detailed video on Growing
and Care tips for neem tree from an end screen
link after this video.
Now, before we discuss on which Neem oil you
should purchase for best efficacy in gardening,
we will list out the best uses of neem oil
for your plants and gardening.
1.
Its By far the best Organic Pesticide available
worldwide.
It has an excellent safety profile and the
best efficacy to treat a large number of pest
attacks on your plants.
It is infact a broad spectrum pesticide effective
on pests like Aphids, Mealybugs, Whiteflies,
Caterpillars,leaf miners, fungus gnats, Thrips
and mites, Greenflies, Grasshoppers and other
Scale insects.
It kills pests in all their lifecyle stages
like the adult stage or the larval stage.
2.
It has the Anti bacterial, anti viral and
anti fungal properties not only for use on
plants but also prescribed for humans and
pets for various skin and hair problems.
3.
Its also effective on Slugs and snails which
eat away a lot of your garden overnight.
I have an important episode to identify some
hidden pests and insects in garden by examining
the leaf signature they leave after feeding
on the leaves.
You can watch that episode from a link in
the video description or from an end screen.
4.
It highly Effective in the Treatment of Black
spot Rose disease, Rose die back disease and
Powdery mildew.
We have detailed episodes on each of these
plant diseases and problems.
You can watch those episodes from the description
links.
5.
Neem cake is an excellent organic fertilizer
for your plants.
Neem cake is the by-product left over after
the process of extraction of neem oil from
neem seeds or neem fruits.
Its not only a source of NPK and micro nutrients
for plant growth, but when mixed with soil
acts as a soil conditioner and also antibacterial
and antifungal.
You can avoid fungus gnats if you incorporate
about 10 percent neem cake powder in your
potting mix.
6. last but not the least is, unlike the chemical
pesticides, It does not affect the beneficial
pollinators like butterflies and honey bees
which are so important for a fruitful gardening.
Now, we will discuss the most important aspect
of this video, based on which the quality,
composition and efficacy of neem oil depends
thats the method of extraction of neem oil
from seeds.
There are three methods:
1.
Heat Pressing method.
2.
Solvent extraction method and
3.
Cold Press method.
Heat pressing method as the name implies,
its using heat for crushing or pressing the
seeds to extract oil.
Solvent extraction means using a solvent like
alcohol is used to extract neem oil.
This solvent extracted neem oil usually has
a low price, because it is turbid and contains
a significant amount of water and metals with
low content of the important compounds namely
azhadiractin and nimbin.
Heat extracted neem oil also has moderate
loss of the useful compounds and less effective.
Whereas the Cold pressed Neem oil extracted
without applying any heat, is the best and
effective source for neem oil.
So, when you are purchasing from a local garden
store or online, make sure you check the method
of extraction mentioned on the bottle or product
description.
I have provided a link to purchase this product
from a link in description below.
Now Finally How to use Neem oil properly for
the best effects.
Now before I start with the neem oil recipes
for plants, the safety profile of neem oil.
It has few effects when concentrated form
is ingested like stomach irritation causing
gastritis and vomiting.
Then Eye irritation and contact dermatitis
can develop on contact specially in children.
Otherwise it has an excellent safety profile
and its completely biodegradable.
Now the recipe for Neem Oil you can make at
Home.
Before this, few important points you must
remember:
1.
Because its an oil, it doesnt mix well with
water and must be mixed with some kind of
surfactant like liquid soap or even shampoo
for proper mixing and the coating effect on
the plant leaves.
2.
Make sure you do not spray neem oil during
the sunlight best time to spray is in evenings
after the sun fades.
To Make the best broad spectrum PESTICIDE
FOLIAR SPRAY FORMULATION for 1 litre:
Take 1 litre Warm Water and add 10 drops of
liquid soap like your handwash or even some
shampoo.
Then you add 5 ml to 10 ml of Neem oil into
this.
5 ml if you want to spray as a maintenance
pesticide spray for your garden where you
do not have much pests.
10 ml if you have lot of pests on your plants.
Mixing this thoroughly before use is very
important.
Perform a PATCH TEST to know how strong it
is.
This means you Just spray this on one or two
leaves and then wait for a couple of hours
to see if the leaf is wilting or burning due
to too much concentration of neem oil.
If you pass the patch test, you can spray
it on your whole garden safely.
Patch test may be important for newbie gardeners
or if you have purchased a new brand of neem
oil from some company for the first time.
Also make sure you spray the underside of
the leaves as well.
3.
How frequently should I use neem oil?
Depending on the severity of pests, use it
twice a week for pest eradication phase and
then weekly once for 1 or two months and finally
if everything is clean use it once every 15
days as a preventive measure.
So, there you have it folks.
