Phytophthora capsici is a serious soilborne pathogen in chile pepper in New Mexico. This mycelial microorganism has been shown to spread under high soil moisture conditions and cause crop loss in a wide array of crops. Outbreak of diseases caused by P. capsici under high soil moisture conditions could be explained from at least two perspectives: (i) increased release and movement of zoospores, and (ii) predispositional effects of soil water saturation on host crops. The increased release of zoospores may be due to several factors including soil solution composition. Very little is known about the relationship between soil solution composition in chile fields in New Mexico and production of zoospores by P. capsici. Soil extracts (2%; 20 g soil per liter of sterile de-ionized water) were prepared from soils sampled from several geographical regions, and evaluated for their effects on production of sporangia and zoospores by P. capsici in the laboratory. Chemical analyses of sampled soils were performed to determine differences in composition of soil samples, and correlation analysis was carried out to assess the association between soil composition and sporangia and zoospore production. From preliminary results, few statistically significant correlations were found between soil composition and production of zoospores, and a significant negative correlation was indicated between copper content of soils and zoospore production by P. capsici.
