Organic Pest Spray

This recipe for an organic pest spray comes from Strawbery Banke.  We are suggesting it for use in the Community Garden and will welcome feedback on it’s effectiveness.  Note that this spray will only work if it is applied frequently and reapplied after rain or heavy morning dew.

Cornell Mix
This is the organic pesticide mix that we use on our plants at Strawbery Banke. The ingredients are inexpensive and the uses are versatile. Works great for a wide range of insect pests and mildews.

You will need:
Spray bottle
1 gallon jug
1 TBS Dr. Bronner’s liquid concentrate soap (or other all-natural liquid soap without phosphates)
1 TBS olive oil
1 TBS baking soda
Warm water

Put small amount of warm water in the bottom of the jug. Add soap, olive oil and baking soda. Swirl ingredients to blend them. Fill the rest of the jug with warm water and then put the cap on. Shake thoroughly. Dispense into spray bottle.

When applying to plants, make sure to get the undersides of leaves, tight crevices and tender new growth. Keep shaking mixture to keep ingredients well incorporated (oil will try to separate). Apply once a week for prevention and more often for an active problem.
