Chemical Controls can be used when all else fails. Selection of a pesticide and a fungicide will depend on the particular pest being combated (which his why proper identification is so important). Sprays are generally more effective than dusts, as nearly all pesticides rely on contact with the pest for their effectiveness. Read the instructions on the chemical containers carefully before using, especially noting whether the chemical is safe to use on food plants. Many times a pesticide will warn against its use for a period of time before harvesting.
