ENY723 Summary of Cotton Insecticide Options for Florida 1 Richard K. Sprenkel 2 Introduction Cotton insect management in Florida utilizes a variety of techniques to suppress insect populations and reduce losses. This publication was developed to provide the user with a summary of the available insecticide options, one of these techniques. For more information on the identification and monitoring of cotton insect pests and their treatment thresholds, see Insect Management in Cotton http://edis.ifas.ufl.edu/ig059 and Cotton Plant and Pest Monitoring Manual for Florida http://edis.ifas.ufl.edu/nfrec21. The use of trade names in this publication is solely for the purpose of providing specific information, UF/IFAS does not guarantee or warranty the products named, and references to them in this publication does not signify our approval to the exclusion of other products of suitable composition. Registered chemicals for non-lepidopteran pests of cotton are presented in Table 1 and insecticides for lepidopteran pests of cotton are presented in Table 2. Insecticides known to provide only marginal control or listed on the label as providing "suppression" of a pest population are indicated by "." Restrictions All pesticides have restrictions on their use. These restrictions may include the maximum number of applications per season, the minimum interval between applications or the maximum amount of a pesticide that may be applied on the crop per season to name just a few. Because of space limitations, associated with the registered pesticides all of the restrictions are not included with the tables referenced below. However, the pesticide label contains all of the pertinent restrictions and the user is required to follow all of the instructions and precautions on the label. 1.
