Cover crops and control of arthropod pests of agriculture
Cover crops can harbor both harmful and beneficial arthropods (1, 3). Damage to cover crops themselves is rarely of concern; more important is the possibility that pests harbored amid cover crops may disperse to adjoining cash crops [see Kennedy and Margolies (31) for a discussion of the dynamics of such mobile pests]. Here, I explore the roles that cover crops play in the life cycles and popul...
متن کاملBt crops benefit natural enemies to control non-target pests
Crops producing insecticidal crystal (Cry) proteins from Bacillus thuringiensis (Bt) control important lepidopteran pests. However, pests such as aphids not susceptible to Cry proteins may require other integrated pest management (IPM) tactics, including biological control. We fed aphids on Bt and non-Bt plants and analyzed the Bt protein residue in aphids and compared the effects of Bt plants ...
متن کاملInfluence of cover crops on insect pests and predators in conservation tillage cotton.
In fall 2000, an on-farm sustainable agricultural research project was established for cotton, Gossypium hirsutum L., in Tift County, Georgia. The objective of our 2-yr research project was to determine the impact of several cover crops on pest and predator insects in cotton. The five cover crop treatments included 1) cereal rye, Secale cereale L., a standard grass cover crop; 2) crimson clover...
متن کاملCover Crops in Sustainable Food Production
Cover crops are important components of sustainable agricultural systems. They increase surface residue and aid in the reduction of soil erosion. They improve the structure and water-holding capacity of the soil and thus increase the effectiveness of applied N fertilizer. Legume cover crops such as hairy vetch and crimson clover fix nitrogen and contribute to the nitrogen requirements of subseq...
متن کاملThinking across and beyond disciplines to make cover crops pay
As the name implies, a cover crop consists of plants grown primarily to keep the land covered, especially during the off-season or between cash crops. In temperate regions like most of Europe and North America, a cover crop sown immediately after the main crop harvest in fall is considered a winter cover crop. It will grow in the fall, either subjected to frostkill or go into relative dormancy ...
