Answer 2

Many organic substances can be used as pesticides. Tobacco, hot peppers, soap, and bleach (probably not organic!) can all be effective. To use hot peppers or tobacco, you should let a small amount (say a few tablespoons) brew in water for several days. dissolve soap in water and then use to dilute the brewed water and spray the diluted mixture on plants (preferrably in the evening after watering). best to be conservative with the dilution as it can burn the leaves if it is too strong!
some plants can be planted in gardens to repel pests. marigolds, basil and many other herbs have these properties. inter-planting different species helps, too.
another natural alternative to pesticides is biological control in the form of other bugs that eat the unwanted ones.

Answer 3

Any substance used to kill pests (plants, weeds, bugs, bacteria) is a pesticide, and pesticide is a generic term for herbicides, insecticide, mitacide, acaracide, biocide, etc.

Replacement for pesticides include management of the pest (meaning, you wipe up ants instead of spray them). The process is called Integrated Pest Management (emphasis on management) and part of that is using least toxic pesticides if you have to take that route. The idea is that pesticides are just one management tool for pests.

There is a fabulous website that talks about Integrated Pest Management athttp://ipm.ucdavis.edu . It should give you lots of ideas of organic substances (such as oils, neem oil, diatomaceous earth, boric acid, etc...).

Answer 4

Bt, Rotenone, pyrethrums, kaolin, Diatomacious earth, wood ash, garlic, soap, hot peppers, row cover, crop rotation, building healthy soil, attracting beneficial insects to your growing area, attracting beneficial animals such as toads, frogs, salamanders, birds, etc., to your growing area, neem oil milk, lime sulphur.

Healthy soils and a balanced eco system on your farm are the best hedge against pests and diseases so it is a wise organic grower who uses pesticides sparingly and only as a last resort when other methods fail and insect/disease populations get out of control.
