Summary of Cotton Insecticide Options for Florida

 Richard Sprenkel

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. For more information on the identification and monitoring of cotton insect pests and their treatment thresholds, see  Cotton Plant and Pest Monitoring Manual for Florida http://edis.ifas.ufl.edu/NFREC21.

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 in this publication, the restrictions are not included here. However, the pesticide 1abel contains all of the pertinent restrictions and the user is required to follow all of the instructions and precautions on the label.

In the following two tables, chemical registered for the control of non-worm pests of cotton (Table 1) and the control of the worm pests of cotton  (Table 2) are presented. Insecticides known to provide only marginal control or listed on the label as providing  "suppression" of a pest population are indicated by “(S)”.  A summary of the restrictions on most of the pesticides is given in (Table 3).

 

All chemicals should be used in accordance with directions on the manufacturer's label.  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.
