英文文献作者：Epperson, James E.,Allison, John R.
英文文献摘要：
The ability to multiple crop in the southern Coastal Plain of the U.S. may allow cultural means which favor less intensive pest control. One of 3 cropping systems under investigation which was selected for economic evaluation showed that within the range of pest control intensities studied, less intensive control resulted in higher net returns.
