In this phased approach to on-farm pest management planning, farmscaping 2nd phase is integrated with other pest management strategies.

For more information, refer to eOrganic’s articles on organic certification. Once information is available on key pests and their natural enemies, the following strategies can be considered:. The supplemental nectar provided by extrafloral nectaries is important, especially during the early season or periods of drought when few plants are in bloom.

Peonies, sweet potato, bachelor button and lima bean are examples of plants with extrafloral nectaries located on various parts of the plant. Consider the Area to be Farmscaped. For example, fennel and colored yarrow varieties can be sold as cut flowers. 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.

In organic systems approved insecticides can be used, but pests can also be eliminated by crop destruction. Recent research has shown that the quality, not quantity, of the farmscape plantings is most important.

Farmscaping is a whole-farm, ecological approach to increase and manage biodiversity with the goal of increasing the presence of beneficial organisms. Ecological engineering for pest management: 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.


Many pest populations can be managed by enhancing the efficacy and local abundance of the existing community of natural enemies through modification of the environment, a concept that has been termed “conservation biological control.

Intercropping, companion planting and trap cropping are three examples:. Remember also that farmscaping plants can add value beyond biological control.

Both practices serve to increase biodiversity and make the habitat less suitable for pest development. In planning the farmscape it is important to enhace specific plants, planting situations, and management practices that best support populations of beneficial organisms.

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 biologicao most important factors in disrupting host location. Insectary plants like mustards interplanted with market crops provide pollen and nectar to attract and maintain beneficial tarmscaping in the crop landscape.

Therefore, a flexible approach is needed to be able to adjust beneficial habitat according to weather conditions. Researchers now commonly screen plant species and use a range of selection criteria to determine appropriate botanical composition. The most successful farmscape systems have been developed and fine-tuned by farmers to fit their individual circumstances. Advances in Habitat Manipulation for Arthropods Farmscaping aims to prevent damaging levels of pests from developing in the crop ecosystem.

Resources Find all of our great resources for organic farming. Pests find it easier to locate host plants when grown in a monoculture versus a mixed planting. Parasitic and predatory insects use extrafloral nectaries as food sources and mating sites. Planting a diversity of flowering plants to enhance biological control has been referred to as farmsfaping box ecology” because of the colorful floral display. There are many different farmscapinv and strategies in farmscaping. The African marigold, for biologiczl, releases thiopene—a nematode repellent—making it a good companion for a number of garden crops.

Successful use of trap crops is challenging.

Observation and experience are the most valuable tools in this regard. These plants have small, open flowers that are accessible to the tiny mouthparts of small, parasitic wasps.


More on trap crops later….

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.

This section will familiarize you with key factors to consider in planning a farmscape for effective biological control, including:.

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. Alternative hosts for beneficial insect prey.

This is where you can find research-based information from America’s land-grant universities enabled by eXtension. Trap crops were originally designed to be used in conventional systems where insecticides could be used to kill the pests in the biokogical crop.

A trap crop is a crop that is planted to lure insect pests away from the cash crop. Browse related by Tag organic productioneorganic. However, using this approach without knowledge of key pests and the interaction among biologocal, pests and natural enemies may lead to failure.

For each market crop to be grown, make a list of the most damaging pests that require management; boological for each pest, try to answer the following questions:. Flowers or extra-floral nectaries provide nectar.

Example of companion planting from left to right; lettuce, cabbage and sunflower. Insect sampling guidelines are available online. Another good pollen producer is the corn plant. Flowering medicinal plants like echinacea, fever few, and boneset also have multiple uses.

Weather variations from year to year may strongly influence whether a particular management practice is effective. Pollen is a source of farmscapingg and protein is critical for egg laying.
