Mulches reduce aphid-borne viruses and whiteflies in cantaloupe

Autor: Charles G Summers, Jeffrey P Mitchell, James J Stapleton

Publikováno v: California Agriculture, Vol 59, Iss 2, Pp 90-94 (2005)

We compared reflective plastic and wheat straw mulches with conventional bare soil for managing aphid-borne virus diseases and silverleaf whitefly in cantaloupe. The occurrence of aphid-borne virus diseases was significantly reduced with both mulches

THE PHENOLOGY AND DISTRIBUTION OF APHIDS IN CALIFORNIA ALFALFA AS MODIFIED BY LADYBIRD BEETLE PREDATION (COLEOPTERA: COCCINELLIDAE)

Autor: J. U. Baumgaertner, Andrew Paul Gutierrez, Charles G. Summers

Publikováno v: The Canadian Entomologist, 112 (5)

The phenologies and distributions of pea aphid (Acyrthosiphon pisum (Harris)), blue alfalfa aphid (A. kondoi (Shinji)), and spotted alfalfa aphid (Therioaphis maculata (Buckton)) were intensively studied in California alfalfa. The results showed, as

Economic Analysis of Three Soil-Surface Practices for Production of Fresh Market Tomato (Solanum lycopersicumL.)

Autor: Charles G. Summers, Jeffrey P. Mitchell, James J. Stapleton, Albert S. Newton

Publikováno v: Journal of Crop Improvement. 27:113-123

Plastic and cover crop mulches are widely used in a number of vegetable crop production areas, but they currently are not commonly used in California. Evaluations of the effects of silver UV reflective plastic (RP) and cool-season cover crop (CC) mul

Population dynamics of arthropods associated with early-season tomato plants as influenced by soil surface microenvironment

Autor: Albert S. Newton, Charles G. Summers, James J. Stapleton, Jeffrey P. Mitchell

Publikováno v: Crop Protection. 29:249-254

Two field studies were conducted in the San Joaquin Valley (SJV) of California in order to describe the association of arthropods and possible virus diseases with the plant canopy of early-season, bush-trained, fresh-market tomato ( Lycopersicon escu

California Agriculture, Vol 63, Iss 1, Pp 35-40 (2009)

Grass cover crops can be harvested for biomass or used as a surface mulch to reduce erosion, improve soil structure, suppress weeds and conserve moisture. There is concern, however, that such plantings may affect subsequent crops. We studied the effe
