Potato leaf and stem desiccation and redroot pigweed control with various products applied alone or in tank mixtures in single or sequential applications

摘要

The objectives of this trial were to determine potato leaf and stem desiccation over a three week period of various desiccants in single or sequential applications in a field trial conducted at the Aberdeen Research and Extension Center in 2005. The experimental area was fertilized with 160 lb N, 80 lb P_2O_5, 10 lb Z, and 5 lb/A of Mn /acre, based on soil tests, before planting 'Russet Burbank' potatoes on May 27, 2005. Potatoes were planted 6 inches deep with 12-inch intervals in rows spaced 36 inches apart in a Declo Loam soil with 1.4% organic matter and pH 8.1. The experimental design was a randomized complete block with three replications and 12 by 30 foot plots.
