Chitin Spray Recipe for fungal diseases and pest infestations:

1/4 cup crab shell flour 

4 gallons water

1 tsp Quantum VSC

Add these ingredients together and let sit for a day or two. During this process, it will smell, and when the the smell starts to go away, thats when you strain the solution, dilute with another 4 gallons of water and spray on your plants. Remember to always spray in the early morning or in late afternoon.  Water on leaves acts like a magnifying glass and will burn them. If you have any leftover solution you can always water it into soil or pour on compost pile.   Please only use this recipe if you have a fungal disease or an infestation of bugs in your garden.

**note this recipe may have a nice crab shell, fishy odor. Best done outside.
