"Organic" Pesticides

The thing I noticed pretty quickly about gardening organically was the plant destroying pests: bugs, weeds and critters. I knew about beneficial insects, the ones that eat the plant destroyers, and how they could be purchased online, mail order, or sometimes from local nurseries. I also knew that hot peppers could be used in some fashion as well. And my organic farmer husband has long used a soap and water mixture to discourage infestations of insects. But an article in the weekend real estate guide from the Sunday, June 11th Denver Post went into glorious detail about organic pesticides, why they work and a recipe to make it. Also included were some tips for reducing the likelihood of infestations.
First, the recipe: 3 garlic bulbs, 12 hot chili peppers, 2 TBSP vegetable oil, 5 squirts liquid dish soap and 7 cups of water. Blend these together using an electric blender and then strain through muslin cloth, storing in a spray bottle. I made a batch, and have initially found it pretty effective. I also noticed that it smells bad, but dissipates quickly. I think the garlic also helps makes it fairly sticky on the plants and cuts off the air supply to most pests.
Next, to attract beneficial insects, we should keep our gardens dry and healthy. Wet plants are more susceptible to infestations and fungus. Keep your garden mulched (you can use organic compost...easy to do with a tumbling composter from BestComposters.com!)so as to prevent weed growth and retain moisture for the plant roots, then trim leaves so that they don't lay on the ground. Certain plants will attract beneficial insects, like carrots, celery, parsley, caraway, Queen Ann's Lace, tansy, yarrow, daisies, blackeyed susans, asters marigolds and goldenrod.
I haven't tried the last steps to protecting my garden yet in any quantity. I do have the first three vegies, but I'm interested in adding some of the flowers around them to see what impact they'll have. I surely wish I could get our Homeowner's Association to ok chickens. I'm told they are a powerful ally in the war against slugs (not to mention the delicious fresh eggs that they give), and I really need an ally for that war!
Happy Composting!
