How much Physan PSPTA20 and water do you use for the mix to be sprayed onto the seeds and newly-sprouted seeds? It says 1.5 tsp/gal on the description. May it harm the newly-sprouted seeds? Is it toxic to humans?
Best
yes onur it's toxic, I'm surprised people still use this crap with all the information available at the fingertips...
From google: "Evidence. EPA's review of industry submitted toxicity data and the potential for human exposure concludes that this substance [alkyl benzyl ammonium chloride] poses a high risk for human health. A peer-reviewed publication reports some quaternary ammonium compounds cause reproductive toxicity in animals.
Quaternary ammonium compounds detected in human blood was associated with increased inflammation, decreased mitochondrial function and disruption of cholesterol."
Thank you Satya.
