Updated DD60 Program for Insecticide and Irrigation Termination of Cotton Now Available
Author: Tom Barber, Extension Weed Scientist

A new weather data collection system for calculation of accumulated heat units is in place in every cotton-producing county in the state, and the University of Arkansas Cooperative Extension Service is offering the first mobile application of such a program which can be easily downloaded to any mobile device for easy, convenient access.  The new DD60 system automatically collects weather data from an Intercept Weather Station and uploads it to the mainframe computer every morning so that producers, agents, and consultants have access to the latest information needed for making termination decisions.

To visit the DD60 webpage from your computer,, click the following link:  From this page, you will be able to access both former and updated DD60 information.  To visit the updated page and link it to your mobile device, click the link that states: New option beginning August 17, 2011:  DD60 accumulation using data from Intercept Weather Stations  via the Arkansas Plant Board.
