using aspirin as resistance to diseases and pests

interesting read under section 2.7 - diseases and pests

 

Cannabis' resistance to diseases and pests can be strengthened by the judicious use of methyl salicylate, which is a major component of wintergreen oil. Aspirin (acetyl salicylic acid) also is effective. Dissolve two tablets in a quart of water and apply the solution as a foliar spray.

 

anyone do this or ever heard of it???

 

btw - 1 quart = @ 950 ml

sounds like crap to me, hopefully someone with too many plants to care about losing a few will give it a try and let us know of the results :scratchin

What he is saying is basically true but could be considered a lost art in today's high tech hydro world where the 'label' is 'everything'.

Salicylic acid is a colorless, crystalline organic carboxylic acid. It is usually prepared by Kolbe synthesis (aka Kolbe-Schmitt reaction). Salicylic acid functions as a plant hormone.

 

Properties

Salicylic acid is toxic if ingested in large quantities, but in small quantities is used as a food preservative and antiseptic in toothpaste. The carboxyl group (–COOH) can react with alcohols, forming several useful esters. The ester with methanol is methyl salicylate, also known under the name oil of wintergreen. The hydroxyl group (–OH) can be acetylated to form acetylsalicylic acid (aspirin). Salicylic acid can also trap oxygen (O2) and initiate free radical reactions.

 

 

Medicinal uses

Salicylic acid is the key additive in many skin-care products for the treatment of acne, callouses and corns, keratosis pilaris and warts. It treats acne by causing skin cells to slough off more readily, preventing pores from clogging up. This effect on skin cells also makes salicyclic acid an active ingredient in several shampoos meant to treat dandruff.

 

The medicinal properties of salicylate (mainly the lowering of fever) have been known since ancient times. The substance occurs in the bark of willow trees and the name Salicylic acid is derived from the Latin name for the Willow tree - Salix.

 

 

Aspirin (acetylsalicylic acid)Aspirin (acetylsalicylic acid or ASA) can be prepared by the esterification of the phenolic hydroxyl group of salicylic acid.

 

Subsalicylate in combination with Bismuth form the popular stomach relief aid known commonly as Pepto Bismol. When combined the two key ingredients help control diarrhea, nausea, heartburn, and even gas. It is also very mildly anti-biotic.

 

 

Salicylic acid as a plant hormone

Here is a list of some of salicylic acid's properties when acting as a plant hormone. It is interesting to note, in light of these properties, that there is a popular belief that cut flowers will last longer if aspirin (acetylsalicylic acid) is dissolved in their water.

 

 

Location, characteristics and occasions for synthesis induction

Cells returning from water stress

Released by cells secure in having more than enough nutrients and environmental conditions locally to survive at its current metabolic level (speculative)

All cells capable of synthesizing

Has its effect or acts by rapid local increases followed by rapid decreases in levels

 

Effects

Retards senescence (regulatory role) – probably by inhibiting Ethylene biosynthesis

 

Induces flowering

Inhibits seed germination – by inhibiting ABA synthesis

May also block the wound response and act antagonistically to ABA, preventing the wound response from spreading further than necessary (speculative)

After a survival threat has passed SA quickly removes a plant, organ, tissue or cell from a defensive posture and returns it to normal "relaxed" functioning (speculative)

 

Increases cell metabolism rate to take advantage of new complete more advantageous nutrient and environmental conditions (speculative)

A climactic or sustained level of SA may occur if a cell has reached its peak metabolic levels and may signal that a plant's resources can be turned to growth (speculative)

 

This climactic or sustained level of SA may be a prerequisite for the synthesis of Auxin and/or Cytokinin, because only then does a plant know that it has enough resources to turn them to growing bigger (highly speculative)

Another good reference to go along with the Wiki entry....

This talks about using Asprin on Orchids - however the comments on the article provide some good insight into the science behind it.... I've noticed everyone tends to have their own dosages - some experimentation might be in order if you wanted to find the best to suit MJ.

[Frazz]

this is bullshit and belongs with Buddy's Myth-Busters ! ::

the orchid/asprin thread was interesting reading thanks eikel. it does add some merit to the theory but still the question is - how much to apply to MJ and how often?

 

as a test, i might try 600mg disolved in 1lt water applied as a foliar spray on one plant and see if anything happens.

[sydneyguy]

It should be interesting to see what happens ! :smoke

[keepleft]

i applied a foliar spray of 1800 mg aspiring with 3 lts of water couple of weeks ago. to a G-room which were in the veg stage. didnt do any harm! but whether it did any good i dont know! there as healthy as anything (nice uniform green leaves, no diseases etc). but that could be cause im using microbial in the nutes!

[WantDaChronic]

sounds like it belongs in the mythbusters topic
