Cotton Report 1984
ABOUT THE COLLECTION
The Cotton Report is one of several commodity-based agricultural research reports published by the University of Arizona.
This report, along with the Forage and Grain Report, was established by Hank Brubaker, Extension Agronomist, after seeing a similar report published by Texas A&M University in the mid-1970’s.
The purpose of the report is to provide an annual research update to farmers, researchers, and those in the agricultural industry. The research is conducted by University of Arizona and USDA-ARS scientists.
Both historical and current Cotton Reports have been made available in the UA Campus Repository as part of a collaboration between the College of Agriculture and Life Sciences and the University Libraries.

Cotton Planting Date and Planting Rate(College of Agriculture, University of Arizona (Tucson, AZ), 1984-02)DPL 41 and Pima S-5 cotton were planted at low, medium, and high planting rates on April 12, April 27, and May 10 on the Safford Experimental Farm in 1983. Heavy rains in late September and early October reduced lint yields. Pima S-5 produced 66% as much lint as DPL 41. Both varieties had the highest lint yield when planted on April 27. The highest planting rate produced the highest yield for DPL 41, while the medium planting rate produced the most lint for Pima S-5 on April 27.
Sweetpotato Whitefly and Parasite Populations in Sprayed Cotton Plots(College of Agriculture, University of Arizona (Tucson, AZ), 1984-02)Two insecticide applications were made to cotton in late August and early September. Higher Bemisia tabaci populations were observed in the malathion treatment, as sampled by vacuum samples, and in the DyloxR and malathion treatments, as sampled by yellow sticky traps. Generally, the numbers of parasites collected were higher in untreated check plots than in the insecticide treated plots.
1983 Pre-Season Trap Catch of Boll Weevil (Coloptera: Curculionidae) in Western Arizona Including a Comparison with the 1982 Catch(College of Agriculture, University of Arizona (Tucson, AZ), 1984-02)An adult boll weevil (Anthonomus grandis complex) trapping network was organized in the major cotton producing areas of western Arizona for the first four months of 1982 and 1983. The results for each year are summarized as the mean number of adult boll weevils caught per grandlure baited trap and adjusted for the number of days each trap was in operation. Where possible, the 6 major cropping areas were subdivided into trapping sectors which permitted more detailed analysis. The results indicate the boll weevil expanded its range in western Arizona between 1982 and 1983. In 1982, they were trapped in 432 of the sectors and in 1983, 96% of the sectors. The results also show an increase in population size between 1982 and 1983. The mean number of boll weevils BW caught per trap per day was 1 to 291 times greater in 1983 depending on trapping sector.
