~• <br />•M <br />u <br />.h <br />a <br />I.E. ~ol pes <br />,;~ical < <br />Biological control is the use of living <br />organisms to control pests. Knowing the <br />life cycles of the pest and its enemies is <br />important to maximizing the effciency of <br />any biological control. <br />^ Encourage beneficial insects by <br />planting a wide variety of plants that <br />flower throughout the year. <br />^ Introduce natural predators, parasites <br />and beneficial microbes. Parasitic <br />nematodes are effective for control of <br />pests. Bacillus thuringiensis (Bt) is a <br />bacterium that kills caterpillars, <br />including those of non-pest moths <br />and butterflies. (Do not use Bt in a <br />butterfly garden.) Compost tea <br />introduces large and diverse <br />populations of microbes that can <br />suppress some leaf and root diseases. <br />^ Buy all biological controls from a <br />reputable source. <br />^ Do not use pesticides, especially <br />broad spectrum pesticides, when <br />using benefcial organisms. <br />^ Goats, used with care, can be an <br />excellent means of controlling poison <br />oak, blackberries and other vegetation <br />and in the process, returning nutrients <br />to the soil. <br />Beneficial organisms feed on or <br />parasitize pests, potentially reducing the <br />cost of purchasing and applying <br />pesticides. Your staff will not be applying <br />dangerous pesticides, which may reduce <br />your liability. <br />^ Metaldehyde ^ Pyrethroids <br />^ Disulfoton Bifenthrin <br />^ Carbaryl • Cypermethrin <br />^ Malathion • Cyfluthrin <br /> • Permethrin <br />^ Pyrethrins <br />^ Imidacloprid <br />^ Fipronil <br />SOURCE: KELLY MORAN & MARY LOUISE FLINT, <br />cc <br />I grew up in the nursery business. <br />The older generation had a lot of health issues, <br />a lot of cancer. For ourselves and our own <br />health and safety, we should try to eliminate <br />toxics. Why should a beautiful landscape be <br />purchased with the health of the people who work on it?" <br />- Glen Schneider, Proprietor, Glen Schneider Gardening, Berkeley <br /> <br />TIPS FOR SUCCESS <br />Attracting Beneficial Insects <br />Attract these <br />beneficial insects By planting these species <br />Bigeyed bug Native grasses <br /> Polygonum sp.
