Progress 10/01/00 to 09/30/06
Outputs
Studies focused on the effect of plant and environmental conditions on performance of standard and newly developed harvest aid materials and utilization of this information to develop effective and profitable harvest aid management systems for both irrigated and dryland cotton production systems in Oklahoma. Annual field experiments and demonstrations were established in multiple areas to determine effectiveness of commercially available harvest aid materials and promising new chemicals in developmental stages prior to market introduction. Evaluations taken on both small plot and large plot experiments included percent open bolls at application, percent defoliation and percent leaf desiccation at 3, 7, and 14 days following treatment, and evaluation of regrowth at 14 and 21 days following application. In addition lint yield percent and HVI fiber properties were evaluated for each treatment. Data generated from this project has assisted Oklahoma cotton producers make
logical and timely decisions on the most effective treatment or combination of treatments to use under specific weather and plant conditions.
Impacts
As a result of these studies, producers will be able to make harvest aid applications that are specific for their cotton condition and anticipated yield. Input costs should be reduced and cotton quality will be improved due to timely harvest of higher quality cotton.

Progress 10/01/04 to 09/30/05
Outputs
New harvest aid materials and/or combinations of materials continue to be evaluated in replicated research plots as well as large scale demonstrations in cotton production areas of Oklahoma. Multi-year results from these replicated experiments are used to develop recommendations for use of harvest aids for Oklahoma cotton producers. Harvest aid recommendations are extended through county educators and at producer meetings prior to the application season. Activities during the 2004 crop year include nine replicated or strip research and demonstration plots, applied by OSU primarily on cotton grown by local producers. Seven presentations were given to producers prior to the application season, and three field tours showing plot results were presented to producers. High micronaire discounts have not been as common this year but we confirmed this prior to harvest by sampling and taking micronaire readings. The OSU micronaire instrument we purchased in 2002 was used to
make this evaluation for producers. In January 2005, I made a presentation in the general session of the Beltwide Cotton Conferences about factors influencing fiber quality, which include some harvest aid recommendations. Cotton research and demonstrations are made available to producers through a report booklet and results are available on the following web site: osu.altus.ok.us

Progress 10/01/03 to 09/30/04
Outputs
Emphasis continues to focus on new products and techniques to prepare cotton for harvest. These include various product combinations, timing of harvest aid applications for maximum yield and fiber quality, and large scale demonstrations of harvest aid activity. Emphasis is placed on economics of specific harvest aid treatments as they are related to yield potential and price of cotton. I continue to have responsibility of Southwest Regional Coordinator for a Beltwide Cotton Harvest Aids Working Group and as part of my responsibilities, I wrote a chapter in a Cotton Foundation Reference Book Series titled Use of Harvest Aids in Cotton. Four replicated experiments and five demonstrations were established in Southwest Oklahoma. In irrigated cotton production, the most effective harvest aid treatments continue to be combinations of Finish plus Def/Folex or Ginstar. The most effective treatments in dryland cotton were Ethephon plus Def, or in lower yielding cotton,
treatments using Gramoxone. I will be giving a presentation at the Beltwide Cotton Conference in the general session on how cotton quality can be improved by management inputs, including harvest aids.
Impacts
As a result of these studies, producers will be able to make harvest aid applications that are specific for their cotton condition and anticipated yield. Input costs should be reduced and cotton quality will be improved due to timely harvest of higher quality cotton.

Four replicated experiments and four demonstrations were established in Southwest Oklahoma. In irrigated cotton production, the most effective harvest aid treatments continue to be combinations of Finish plus Def, Folex or Ginstar. The most effective treatments in dryland cotton were Ethephon plus Def, or in lower yielding cotton,

I continue to have responsibility of Southwest Regional Coordinator for a Beltwide Cotton Harvest Aids Working Group and as part of my responsibilities, I wrote a chapter in a Cotton Foundation Reference Book Series titled Use of Harvest Aids in Cotton. Five replicated experiments and six demonstrations totaling approximately 200 acres were established in Southwest Oklahoma. In irrigated cotton production, the most effective harvest aid treatments continue to be combinations of Finish plus Def, Folex or Ginstar. The most effective treatments in dryland cotton were Ethephon plus Def, or in lower yielding cotton, treatments using Cyclone. This year,
Ginstar was very effective in controlling regrowth when used alone or in combination with ethephon materials.

Progress 10/01/00 to 09/30/01
Outputs
Harvest aid studies have focused on new products and combinations, timing of harvest aid applications for maximum yield and fiber quality, and large scale demonstrations of harvest aid activity. An invited presentation on timing of harvest aids was presented at the general session of the Beltwide Cotton Conferences in January. I assumed responsibility of Southwest Regional Coordinator for a Beltwide Cotton Harvest Aids Working Group and as part of my responsibilities, I wrote a chapter in a Cotton Foundation Reference Book Series titled Use of Harvest Aids in Cotton. (in press). Four replicated experiments and approximately 250 acres of demonstrations were established in Southwest Oklahoma. The most effective harvest aid treatments in irrigated cotton were combinations of Finish plus Def, Folex or Ginstar. The most effective treatments in dryland cotton were Ethephon plus Def, or in lower yielding cotton, treatments using Cyclone.
