We conducted a cropping systems experiment in central Pennsylvania, USA, to determine the effects of initial cover crop species and soil management on the abundance and composition of the ground-dwelling
Soilborne organisms are becoming more difficult to control due to pathogen resistance and restricted use of some chemicals. The cost of chemicals is also becoming a concern. Brassicas are of

The potential benefits of different covercrops, biological control amendments, and vegetable rotation on soil chemical and biological properties, crop development and yield, and disease development in organic vegetable production, as
Cover cropping is a common practice in U.S. Midwest carrot production for soil conservation, and may affect soil ecology and plant-parasitic nematodes—to which carrots are very susceptible. This study assessed
Cover cropping is a prevalent conservation practice that offers substantial benefits to soil and water quality. However, winter cereal cover crops preceding corn may diminish beneficial rotation effects because two
Radish (Raphanus sativus) is a great addition to almost any cover crop mix, and NRCS commonly recommends cover crop mixes that include radish as a component. However, radish has many
Brassica green manures have the potential to provide biological control of several common potato pests, including soil borne diseases, nematodes, and weeds. Therefore, a three-year, multidisciplinary study to evaluate pest
Substantial reproduction of Meloidogyne incognita on winter cover crops may lead to damaging populations in a subsequent cotton (Gossypium hirsutum) crop. The amount of population increase during the winter depends
In fall 2000, a non-farm sustainable agricultural research project was established fo rcotton, Gossypium hirsutum L., in Tift County, Georgia. The objective of our 2-yr research project was to determine

Two experiments were conducted in north-central Florida to examine the effects of various winter cover crops on plant-parasitic nematode populations through time. In the first experiment, six winter cover crops
In a 3-year field study, population densities of Belonolaimus longicaudatus and other plant-parasitic nematodes and crop yields were compared between potato (Solanum tuberosum) cropping systems where either sorghum-sudangrass (Sorghum bicolor
Several potential cover crops were evaluated for their susceptibility to Meloidogyne arenaria race 1, M. incognita race 1, and M. javanica in a series of five greenhouse experiments. No galls
A series of laboratory and field experiments were conducted to compare larval development, feeding behavior, and ovipositional preference of fall armyworm (Spodoptera frugiperda) on a standard host plant, a standard
Biofumigation is the suppression of soil born pests and diseases through the use of plants that produce inhibitory chemicals, also known as secondary metabolites. In most cases these biofumigant plants
The effect of an irrigated buckwheat cover crop on populations of beneficial insects and grape pests, vine growth, grape yield, and berry quality was investigated over 1 year in a
Researchers with the University of Arkansas System Division of Agriculture are conducting experimental trials that may help the state’s watermelon growers improve their yields while improving the soil and reducing
