Hydrogen Peroxide - Warning - Heavy Science

Rainy Tuesdays & Peroxide

Post  WriterCPA on 8/6/2013, 5:16 pm

I revised my planting plan, organized seeds for my fall garden and picked up popsicle sticks to mark my plants. All for naught! And I'm one day closer to the first frost.

I am glad of the light, steady soaking rain we're getting, but I was soooo ready to get my hands into the dirt and compost to my plots today. Sad Instead, I opened the compost barrels to gather the free moisture.

I took a walk out to the SFG and things are looking better. I don't know if it is the hydrogen peroxide, the rain, or both. The amount of white spotting seems down, so my fingers are crossed. Does anyone know if I am supposed to reapply the peroxide after rain?

Hydrogen Peroxide - Warning - Heavy Science

Post  WriterCPA on 8/6/2013, 11:53 pm

Apparently plants generate hydrogen peroxide (H2O2) when they are attacked.

This was summarized in Hydrogen peroxide is generated systemically in plant leaves by wounding and systemin via the octadecanoid pathway.  Martha Orozco-Cardenas and Clarence A. Ryan. Published in the Proceedings of the National Academy of Sciences.  May 25, 1999. vol. 96 no. 11
http://www.pnas.org/content/96/11/6553.full

"The wound-generated H2O2 in the [plant] veins also could have a defense role against bacteria, fungi, or viruses as they invade leaves wounded by herbivores. The elevated H2O2 levels also may potentiate the plants’ defense responses against invading pathogens, in which {reactive oxygen species] ROS play an important role. The presence of H2O2 in the plant in response to herbivory, before the pathogen invasion, could be advantageous because timing of the induction of defense responses can be an important factor in the success or failure of plants to defend against pathogen attacks (26)."

It was also interesting to learn that after wounding, some plants synthesize their own salicylic acid (aspirin).  Amazing! Our veggies clean their wounds and then take two aspirin until the gardener comes in the morning.
