Some of the best, effective, yet safest, pesticides and fungicides for organic garden use can be made without using any dangerous chemicals. The best way to control harmful pests and insects is to design your total garden landscape and annual gardening strategy to incorporate continuous companion planting ideas and various intense gardening and biodiversity concepts in order to increase beneficial insect and animal populations to control the harm animals and insect populations. Intensive organic mulching through your garden landscape also controls many pests. Some advanced organic gardeners don't even use any natural pesticides or fungicides, because their soil structure and garden techniques encourage massive populations of beneficials.

However, there are exceptions where a few ideas are needed to control pests. Here is a simple list of classic organic and natural concepts:

1. Companion planting and intense gardening - you can plant certain plants close together to help fight diseases, control pests, or even improve the soil for its neigboring plants' health.

2. Garlic, onions - all alliums are great for killing soft body insects. Flying insects can be paralyzed by direct hits. Also a great fungicide. Best if crushed or liquified in a vegetable oil tea. Use several cloves of garlic per gallon of water.

3. Hot peppers - fresh or powder is great for repelling rabbits and other pests. Many soft body insects can be killed by its acidic "burning" effect. Best when mixed with garlic sprays applications.

4. Canola oil, vegetable oils - mineral oils work also, but they are made from petroleum products. Oil sprays suffocate soft body insects. Don't use too much on sensitive plants. May burn leaves. Don't use no more than 1 cup of oil per gallon of water.

5. Alcohol - rubbing alcohol is good but it is made from petroleum products. Drinking alcohols are made from plants. Using only a few tblsp per gallon of water will kill many soft body insects. Too much alcohol in water will produce a super herbicide.

6. Apple Cider Vinegar - Use 1-2 tbls per gallon of water for a mild fungicide or acidic liquid fertilizer. Like alcohol can be a natural herbicide if too much is used in tea. Most white vinegars are made from petroleum products. Apple cider vinegar can contain up to 30 trace elements.

7. Corn meal - Use as a topdressing or in a tea for fungal control.

8. Compost teas - This multi-purpose fluid can contain beneficial microbes and soluble nutrients that can be a mild fungicide and disease controller.

9. Ground cloves - great repellant and can kill flying insects. Use several tblsp per gallon of water.

  1. Japanese beetles - these pests are best controlled by killing their larva during the winter and early spring seasons with mild topsoil tilling, or using milky spore or beneficial nematode soil applications. During the warm season, the best way to control them is with traps. Simple inexpensive traps can be made by...
