Jeff Chandler is a Horticulturist with Cornflower Farms P.O. Box 896 elk grove Ca. 95759 (916)689-1015 or fax (916)689-1968- Jeff had slides of Beneficial insect Plants that they raise at Cornflower farms. They raise useful plants for wildland restoration and enhancement and agricultural applications. Plants for drought tolerance, creating wildlife, beneficial insect, butterfly and hummingbird habitat, fire and erosion control, native grasses, windbreaks, etc. The beneficial insect plants they offer are longlasting and provide food, enhanced habiat, and over-wintering sites for natural enemies of many agricultural pests. Once established these plants demand minimal if any care and can deliver years of benefit.
Some Pest and Beneficial Insect Associations
Beneficial insect plants can thrive in noncrop areas such as field margins, hedgerows, easements, roadsides, and wildlands near cropland and refuges within cropland. Beneficial insect plants include trees, shrubs, groundcovers and grasses. Insectary plantings can also be designed to attract other desirable wildlife, help suppress weeds, increase biodiversity, improve esthetics while enhancing biological control of insects and other pests. Designing a beneficial insect planting entails providing beneficial insects with a year-round habitat including food (pollen, nectar, and sometimes prey and overwintering sites, even when pest populations are low. Various combinations of plants attract beneficials by providing flowers through out the year (see the accompanying chart). The best mix of insectary plants for enhancing control of specific pests depends on the crops grown and times of greatest susceptibility. The plants we've listed include both California natives and non natives. While many species are drought tolerant, supplemental watering can greatly enhance and extend flowering periods.
