Papaya Leaf FPJ as a BioPesticide

Answered

Papaya leaves contain papain, a proteolytic enzyme which is a naturally occurring bio-pesticide. As such I was wondering if could apply Papaya Leaf FPJ as a pesticide?

The process of fermentation eliminates many of the pesticide type functions when making KNF Food. In fact, many things that are known poisons are made edible after fermentation has elapsed, so I am very skeptical of the papaya leaf KNF Food being an effective pesticide.

You may find it works, but in my best understanding, it acts as a food to stimulate good biology rather than killing or inhibiting something you want to eliminate. I have made KNF Food from papaya leaves and it was quite tasty, though I prefer to make it from the fruits for my purposes.

If you are looking for an effective way to get the proteolytic enzyme from papaya leaves, perhaps consider putting them in a pressure cooker with water and cooking them for many hours until the water reduces in half. This dark slurry is then strained and combined with liquid soap to become an effective pesticide.

Hi, searching about the extraction of papain, I found that you can scratch the skin of a green papaya with a knife (Not taking out the green papaya) to extract the papain, the process is repeated every 2 weeks and Mature fruits are discarted (may be used for some fpj or compost) , this will greatly decrease the production of papaya in this plant.
For papain dilution mix it with water and use a filter, I haven’t tried it , maybe I’ll try it this week and let’s see what happens!

that’s were I found it
Peace
