I got neem. Near my apartment, I have a friend who manage trading post.
Fortunately i have known him through a lady who is working green house company.
Then He had neem oil from manila.
I requested to him to bring it up here.
Then this evening at last i got neem oil.
This neem oil is from India, and good for human body.
But not good for drinking.
Anyway I want to use experiment as a insecticide, mixing with wood vinegar.
Usually neem oil, even neem plant act insecticide.
Actually it is not killing insect.
It has substances insects to avoid.
And also for antipruritic.
There are just a part of neem effects.
Neem has still a lot of effects.
...
Then why i wanted to get this oil...
I mix this oil with wood vinegar.
The ratio is neem oil : mokusaku = 100mL : 10L
Then we can spray as a insecticide.
This ratio is this liquid : water = 1 : 200.
So in this project, we are going to experiment.
