Once information is available on key pests and their natural enemies, the following strategies can be considered:. Once the farmscape bjological in place, regular monitoring of plants will indicate whether a healthy population of beneficial insects has been established. If planting as a market crop, let some plants go to seed and overwinter to provide an abundance of flowers next season.

Another good pollen producer is the corn plant. Fennel both the common and bronze varieties is not only attractive to small parasitic wasps but its flowers also attract syrphid flies, lacewings, mantids, lampyrids lightning bugs and ladybugs. Flowers that provide pollen. Ecological engineering for pest management: These plants have small, open flowers that are accessible wnhance the tiny mouthparts of small, parasitic wasps.

The most successful farmscape systems have been developed and fine-tuned by farmers to fit their individual bioloyical. This requires some information-gathering and management enjance on the part of the grower, but this investment can result in the following benefits:. For controk, syrphid fly adults can travel over long distances, so food plants established in just one location could support syrphids that could travel over the entire farm. Alfalfa planted as a trap crop in strawberries to control tarnished plant bug.


The supplemental nectar provided by extrafloral enhancce is important, especially during the early season or periods of drought when few plants are in bloom. Successful use of trap crops is challenging. More on trap crops later…. For more information, refer to eOrganic’s articles on organic certification. Interplantings of non-host crops may enhnace act as a food source or habitat for beneficial organisms. More research is needed farmscaing understand the complex interactions among pests, natural enemies, and mixed crop habitats.

View publishing information about this page. In a pest management context companion plants are usually added to deter or repel pests. An excellent reference on the topic is Ecological Engineering for Pest Management: Likewise, natural enemies require adequate supplies of nectar, pollen and plant-feeding insects and other arthropods as food to sustain and increase their populations. The trap crop can be a different plant species, a different variety, or just a different growth stage of the same species, as long as it is more attractive to the pests when they are present.

Before planning the farmscape, collect as much information as possible.

To attract small parasitic wasps or ladybugs with a much more limited range, it is necessary to establish food plants in several areas of close proximity to the crop.

Always check with your organic certification agency before adopting new practices or using new materials. Ideal farmscape plantings provide food and shelter for beneficial organisms, suppress weeds, and grow in close proximity to the cash crop farmscapimg competing for space light, water and nutrients.

One common approach in farmscape planning is to first think about the intended crop, then the key pest s that are known to attack the crop, then determine the commonly occurring natural enemies of the pest sand identify appropriate food plants and harborage requisites.


Trap crops were originally designed to be used in conventional systems where insecticides could be used to kill the pests in the trap crop.

Geoff Zehnder, Clemson University. There are many different approaches and strategies in farmscaping.

Farmscaping: Making Use of Nature’s Pest Management Services – eXtension

This is a broad topic that refers to the addition of specific plants to enhance the growth and quality of nearby crops. For example, fennel and colored yarrow varieties can be sold as cut flowers. Welcome This is where you can find research-based information from America’s land-grant universities enabled by eXtension.

However, using this approach without knowledge of key pests and the interaction among plants, pests and natural enemies may lead to failure. Both practices serve to increase biodiversity and make the habitat less suitable for pest development. Priority is given to preventative pest management strategies farmscapinb farmscaping, followed by more direct measures if preventative strategies are not sufficient.

Simply adding attractive flowering plants to the farmscape without knowledge of the biology and behavior of key pest and natural enemy species will not result in effective biological control. Contol term is used because we are providing food and habitat for the top animals in the food chain, the predators and parasites.

Wild parsnip left and Figure 7. Insect sampling guidelines are available online.

Insectary plants like mustards interplanted with market crops provide pollen and nectar to attract and maintain beneficial insects in the crop landscape.

Pests find it easier to locate host plants when grown in a monoculture versus a mixed planting. Researchers now commonly screen plant contro, and use a range of selection criteria to determine appropriate botanical composition.
