#1 Daughter says methanol is being metabolized by the plant and will, to a certain extent, encourage plant growth (this is all chemistry so don't ask me too explain
) but it is working like a high powered fertilzer. A little bit goes a long ways and you can disable the metabolism of your plants with too much. The effect could last for weeks.
Ethanol doesn't metabolize correctly and will have the opposite effect stunting or killing plants.
So people can drink ethanol but not methanol and plants can drink methanol but not ethanol. Because of the way plants create and use sugar, they break down a different set of alcohols without being poisoned. We don't create sugars, just metabolize them - its a completely different chemical reaction.
Isopropyl alcohol is good for killing bugs, that's it.
Ethylene glycol inhibits the ability of plants to take up water and sugars and they will die.
