In some situations it is useful to establish plantings that will support prey populations that can provide food for natural enemies to sustain their initial establishment into the area. This requires some information-gathering and management skill on the farscaping of the grower, but this investment can result in the following benefits:.
Farmsca;ing is a source of liquid sugar energy and vitamins for beneficials, and is critical for optimum performance. 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. Strip cropping is a derivation of intercropping and is the practice of growing two or more crops in alternating strips across a field. Before planning the farmscape, collect as much information as possible.
Flowering plants provide many of the food resources natural enemies need. Successful use of trap crops is challenging. Priority is given to preventative pest management strategies like farmscaping, followed by more direct measures if preventative strategies are not sufficient.
(fwd) New: Farmscaping to Enhance Biological Control [ATTRA]
Consider the Area to be Farmscaped. Weather variations from year to year may strongly influence whether a particular management practice is effective. More on trap crops later….
For example, fennel and colored yarrow varieties can be sold as cut flowers. The most successful farmscape systems have been enhane and fine-tuned by farmers to fit their individual circumstances.
Recent research has shown that the quality, not quantity, of the farmscape plantings is most important. However, creating a farmscape of flowering plants picked at random may favor pest populations over beneficial organisms.
Snhance Patricia Glynn Tillman centertechnician Kristie Graham rightand student technician Brittany Giles evaluate a sorghum trap crop being used to control stink bugs in adjacent fields of peanuts and cotton. Intercropping is the practice of growing two or more crops usually different families in the same area.
Likewise, natural enemies require adequate supplies of nectar, pollen and plant-feeding insects and other enhancw as food to sustain and increase their populations. A recent study on the effects of non-host companion plants on host finding by the cabbage root fly and onion fly demonstrated that companion plant odor had little or no effect, but that plant size, leaf area and color were the most important factors in disrupting host location.
Try asking one of our Experts. Once information is available on key pests and their natural enemies, the following strategies can be considered:. This term is used because we are providing food and habitat for the top animals in the food chain, the predators and parasites. Browse related by Tag organic productioneorganic.
The African marigold, for example, releases thiopene—a nematode repellent—making it a good companion for a number of garden crops. Interplantings of non-host crops may also act as a food source or habitat for beneficial organisms.
Arthropod pest management in organic crops. View publishing information about this page. The optimum area of the farm devoted to farmscaping depends upon the dispersion capabilities of the beneficials you want to attract see Table 1 below. Farmscaping methods include the use of insectary plants, hedgerows, cover crops, and water reservoirs to attract and support populations of beneficial organisms such as insects, spiders, amphibians, reptiles, bats, and birds that parasitize or prey upon insect pests.
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. Ideal farmscape plantings provide food and shelter for beneficial organisms, suppress weeds, and grow in close proximity to the cash crop without competing for space light, water and nutrients.

Simply adding attractive flowering plants to the farmscape farmscaoing knowledge of the biology and behavior of key pest and natural enemy species will not result in effective biological control. Follow this link to a sample budget for establishment and maintenance of beneficial insect habitat: If planting as a market crop, let some plants go to seed and overwinter to provide an abundance of flowers next season.
Pollen is a source of protein and protein is critical for egg laying. Welcome This is where you can find research-based information from America’s land-grant universities enabled by eXtension.
Pests find it easier to locate host plants when grown in a monoculture versus a mixed planting. Wild parsnip left and Figure 7. Both practices serve to increase biodiversity and make the farmscapint less suitable for pest development. This is an eOrganic article and was reviewed for compliance with National Organic Program regulations by members of the eOrganic community.
More research is needed to understand the complex interactions among pests, natural enemies, and mixed crop habitats. Planting a diversity of flowering plants to carmscaping biological control has been referred to as “chocolate box ecology” because of the colorful floral display.
Therefore, a flexible approach is needed to be able to adjust bioloyical habitat according to weather conditions. A trap crop is a crop that is planted to lure insect pests away from the cash crop. Farmscapingg 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.
This is a broad topic that refers to the addition of specific plants to enhance the growth and quality of nearby crops. The timing is critical — destruction too early or too late can negate the trap crop effects or even result in mass pest migration to the cash crop. In organic systems approved insecticides can be used, but pests can also be eliminated by crop destruction. Farmscaping is a whole-farm, ecological approach to increase and manage biodiversity with the goal of increasing the presence of beneficial organisms.
However, using this approach without knowledge of key pests and the interaction among plants, pests and natural enemies may lead to failure. Insectary plants like mustards interplanted with market crops provide pollen and nectar to attract and maintain beneficial insects in the crop landscape.
Research has shown that for a typical parasitic wasp, egg laying capacity can be 10 times greater for females given a high quality nectar diet compared with females given a poor quality diet.
For example, 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.

Example of companion planting from left to right; lettuce, cabbage and sunflower. Rather, it is an ecological approach or tool that can be combined with other pest management strategies as part of an integrated organic pest management program.
Livestock producers will tell you that their animals are healthier and reproduce more readily when provided an adequate and nutritious diet.
