Neutralizes and Pesticides and their Sequence of Application to Acid-delinted Cottonseed: Effects on Germination, Stand, and Verticillium Wilt of Cotton1
- Earl B. Minton2
Neutralizing acid residues on cottonseed after HCl delinting contributed to seedling emergence and survival in field plantings and emergence in greenhouse plantings, but not necessarily to survival in the greenhouse where seedling diseases were severe or to germination in the laboratory. Similar results were obtained with an experimental neutralizer (EN) and the standard neutralizer (NH3) used alone or in combination with fungicides and the insecticide, disulfoton. The percentage of plants with foliar symptoms of Verticillium wilt was reduced by the neutralizers and pesticides. Decrease in wilt symptoms was related to increased plant populations. Percentage germination, emergence and survival of seedlings and Verticillium wilt were similar when EN and pesticides were applied simultaneously or sequentially. Use of EN can eliminate ammonia and ammonium chloride pollutants currently associated with acid delinting of cottonseed.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
