Última An Evaluation of the Organic Cotton Marketing Opportunity AgEcon Funtanilla, Margil; Lyford, Conrad P.; Wang, Chenggang. The organic cotton market has been growing internationally and presents a potential opportunity for producers. This article evaluates prices and returns for organic cotton production in Texas using a stochastic frontier approach. Organic producers were found to be more profitable relative to conventional production, but the analysis showed that organic producers were relatively less technically efficient.

The government of Uganda is currently testing the performance of genetically modified (GM) cotton varieties. Cotton is cultivated in Uganda for two main reasons: 1) agro-ecological conditions favor cotton cultivation, and 2) there is a long tradition of cotton cultivation in the country. Two main research questions are addressed in this study: a) would the adoption of genetically modified (GM) cotton benefit Ugandan farmers? b) Would the use of GM seed be more profitable than the low input traditional system or than the organic production system? Stochastic budget analysis is used to address these questions. The results show that estimated values of cotton profitability do not seem to justify the investment in a complex technology. The question then is how...

Ano: 2009 URL: http://purl.umn.edu/51823 The control and protection of cotton plants using natural insecticides against the colonization by Aphis gossypii Glover (Hemiptera: Aphididae) - doi: 10.4025/actasciagron.v35i2.15764 Agronomy Pinto, Ezio Santos; Universidade Federal Rural de Pernambuco; Barros, Eduardo Moreira; Universidade Federal Rural de Pernambuco; Torres, Jorge Braz; Universidade Federal Rural de PernambucoUFRPE; Neves, Robério Carlos dos Santos; Universidade Federal Rural de Pernambuco. The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a key pest of cotton, irrespective of the use of conventional or organic management. In organic systems, however, the use of synthetic insecticides is not allowed, increasing the difficulty of controlling this pest. This work evaluated aphid control and the ability of products to prevent aphid infestation using natural insecticides compared to a standard synthetic insecticide. The control trial was conducted with four products [Beauveria bassiana (Boveril®), neem oil (Neemseto®), and cotton seed oil compared to thiamethoxam (Actara®)], and untreated plants served as the control group. The trial testing the efficacy of these products in preventing aphid infestation was conducted...
