552 - Pest Alerts by Text Message

The Agriculture and I/T departments at American Crystal Sugar Company have cooperated with the NDSU NDAWN system managers to develop several pest alert programs for this growing season. The pest alerts will be available to shareholders, agriculturists, and allied industry. The pest alerts are designed to be an early warning system for onset of pending disease and insect problems. The overall objective is to provide real time information to maximize effectiveness of pesticide applications.

Manage the following pests more effectively with timely text message alerts.

Which Pest Alerts Will Be Available?

1. Soil temperature for Rhizoctonia fungicide timing.

2. GDD for application of second insecticide granules for root maggots.

3. GDD for peak fly emergence and post emergence insecticide applications

4. Daily infection value alerts for very favorable Cercospora development conditions.

What Message Will Alerts Convey?

  • One alert when "a 2 day average soil temperature reaches 60ºF
  • One alert when "a 2 day average soil temperature reaches 65ºF
  • One alert when "a 2 day average soil temperature reaches 70ºF

2. Second insecticide granule timing for root maggot when accumulated soil GDD reaches 450.

3. An alert just before peak root maggot fly emergence based on accumulated soil GDD of 590.
