www.sare.org publications crop-rotation-on-organic-farms guidelines-for-intercropping using-trap-crops-to-reduce-pests Using Trap Crops to Reduce Pests Designing a successful strategy for trap cropping requires a sophisticated understanding of the pest insect: its host plant preferences, pattern of movement, and timing of infestation and reproduction. One strategy that has recently proved successful for several species is perimeter trap cropping. This method is used for pest species that move into a field from […]

Many parasitoids are limited to a narrow range of insect hosts. Some of these use plant odors or visual cues to locate their hosts by first finding the plants on which the hosts are located. […]

Choosing an intercrop that does not host key pests on the main crop is critical. Intercropping usually does not reduce, and may even […]

Partial shade cast by a trellised crop or a well-spaced planting of sweet corn can reduce heat stress of summer crops of spinach or lettuce (19). This may be useful in […]
www.sare.org publications crop-rotation-on-organic-farms guidelines-for-intercropping intercropping-legumes-with-nonlegumes Intercropping Legumes with Nonlegumes Legumes like beans and alfalfa have nitrogen-fixing bacteria associated with their roots. Consequently they compete only slightly with nonlegumes for soil nitrogen and in some cases even supply nitrogen to adjacent plants via leakage and root decomposition (fine roots grow and die rapidly within the season, even in healthy plants). For example, field pea can […]
