European corn borer, Ostrinia nubilalis (Hübner), is a major pest of processing snap bean because larvae are contaminants in pods. The incidence of O. nubilalis-contaminated beans has become uncommon in New York, possibly because widespread adoption of Bt field corn has suppressed populations. Snap bean fields located where Bt corn has been intensively grown in space and time may be at lower ri...

Snap bean (Phaseolus vulgaris L.) is a major crop in the Great Lakes region of the United States. The most significant production occurs in Wisconsin, Michigan, New York, Illinois, and Pennsylvania. Snap bean crops also are produced in the Pacific Northwest, Georgia, Florida, and Ontario, Canada. In 2005, 124,367 ha of snap bean were harvested with a farm gate value of approximately $400 millio...

Liu G.D., Morgan K., Hogue B., Li Y.C., Sui D. (2015): Improving phosphorus use efficiency for snap bean production by optimizing application. Hort. Sci. (Prague), 42: 94–101. Phosphorus (P) is essential for crop production. Adequate application P rate is critical for enhancing productivity and profitability of snap bean (Phaseolus vulgaris L.). The goal of this study was to optimize P applicat...

High quality water is less available for agriculture and thus farmers often use saline water, that affects crop growth and yield. Snap bean (Phaseolus vulgaris) is sensitive to soil and water salinity, and also to heat stress. The aim of this research is to evaluate if a postponed transplant (high temperature stress) of snap bean can influence growth and yield under saline conditions. Snap bean...

Beginning in 2000, snap bean (Phaseolus vulgaris L.) crops exhibiting virus-like symptoms on the foliage (leaf distortion, yellow and green mottling, and mosaic) were increasing in frequency on a regional scale across the northern United States and Canada (10,20). These crops also produced fewer pods or pods that were either twisted or necrotic (hence unmarketable). Across the Midwest and north...

Four populations of the lesion nematode Pratylenchus brachyurus were tested in a greenhouse on seven selected plant species to determine host suitability and usefulness in identifying physiological races of the nematode. The differential plants were 'Florida 77' alfalfa, 'Harvester' snap bean, 'Rough Lemon' citrus, 'Pioneer 304C' corn, 'Florunner' peanut, 'Braxton' soybean, and 'Rutgers' tomato...

Cucumber mosaic virus (CMV) has become a major limiting factor in snap bean production in the Great Lakes region of North America, and epidemics have occurred more frequently since the soybean aphid, Aphis glycines Matsumura, was introduced. Major aphid vectors of CMV epidemics were identified by statistically relating their temporal dispersal trends to the incidence of CMV. Alates were monitor...

Cucumber mosaic virus (CMV) is a major component of the virus complex that has become more pronounced in snap bean in the midwestern and northeastern United States since 2001. Multiple-vector-transfer tests were done to estimate the CMV transmission efficiencies (p) of the main aphid species identified in commercial snap bean fields in New York and Pennsylvania. The four most efficient vectors ...

BACKGROUND Multiple applications of pyrethroid insecticides are used to manage European corn borer, Ostrinia nubilalis Hübner, in snap bean, but new diamide insecticides may reduce application frequency. In a 2 year small-plot study, O. nubilalis control was evaluated by applying cyantraniliprole (diamide) and bifenthrin (pyrethroid) insecticides at one of three phenological stages (bud, bloom ...
