Rhizoctonia Management Tips

  • Use the Crystal App and NDAWN to track soil temperatures to time your fungicide applications
  • Remember Kabina will only provide 4-5 weeks protection against Rhizoctonia
  • Refer to Rhizoctonia township maps to identify most severe problem areas
  • Apply POST fungicides no later than the 6 leaf stage
  • If no Kabina or in-furrow treatments were used apply POST fungicides when the soil temperature threshold is reached
  • Contact your agriculturist for more information

Maximizing Weed Control

"It's imperative every possible effort be made to achieve total weed control in all crops in sugarbeet rotations…"

The presence of resistant weeds in the American Crystal Sugar Company growing area makes it absolutely necessary to achieve complete weed control in 2014 and beyond. No weeds can be allowed to go to seed in any Roundup Ready® crop in the rotation. Weeds of greatest immediate concern are Waterhemp, Common and Giant Ragweed, and Kochia. If resistant Kochia, which has been documented in the southern RRV spreads northward, weed control costs in sugarbeet will rise dramatically. It's imperative every possible effort be made to achieve total weed control in all crops in sugarbeet rotations to preserve glyphosate technology for your weed control program in beets.

Maximize Glyphosate Product Activity

  • Begin when beets and weeds are in the cotyledon stage
  • Use maximum allowable rates
  • Best control is from 10 a.m. to 4 p.m.
  • Add 8.5 to 17 lbs. of AMS per 100 gallons of spray solution
  • Control is often better with lower volumes, about 10 gpa
  • Rain within 6 hours may reduce weed control
  • Avoid spraying with dust on plants
  • Avoid spraying with dew on plants
  • Cool weather slows activity and time needed for control
  • Frost before application will reduce control
  • Drought slows weed growth, reduces activity
  • Air temperature over 85°F during application can reduce weed control
  • Don't spray after sunset-weed control can be reduced

Tank Mixes With Glyphosate Critical to Success

  • For resistant Common Ragweed use 3-4 oz. of Stinger in each application.
  • Use Betamix and 4 oz. of Nortron/ethofumesate when resistant Waterhemp is present
  • Use split applications of Outlook or Dual in early layby applications for season long resistant weed control
  • Start layby applications at the 2-4 leaf stage
  • Use 0.5-1.0 oz/acre Upbeet for waterhemp

BE RIGHT!

RIGHT RATE - RIGHT TIMING - RIGHT TANK MIX

Maximizing Formulation Product Effectiveness

It is critical we properly use all herbicide FORMULATIONS containing glyphosate. Proper use maximizes weed control and reduces opportunity for resistant weed development.

USE CORRECT RATES. There are about 70 glyphosate formulations labeled for sugarbeet use. There are 7 different amounts of acid equivalent (active ingredient) being marketed. The correct amount of product to use will vary by nearly 50% depending on your product of choice, see Table 1.

Equivalent Rates for Different Formulations

Acid Equivalent.75 Lbs./A.98 Lbs./A1.125 Lbs.

4.7 20 26 30
5.0 18 24.5 28

* All rates should be equivalent to this accepted standard

Use Layby Herbicide

If resistant waterhemp is suspected, use layby Dual, Outlook or Warrant. The NDSU weed control guide indicates Warrant is less effective on Waterhemp. If Warrant is used you cannot replant the field to sugarbeets.

NDSU Pest Management App

Ndsu591


The NDSU Pest Management app combines select information from the Weed Control Guide, Fungicide Guide and Crop Insect Management Guide. Information in the app is grouped by diseases, insects and weeds for each crop (corn, dry bean, potato, small grains, soybean, sugar beet, and sunflower). Pest management options are provided through a user-selection process. Once a management strategy is selected, the user can view rates, mode of action, general information and additional resources. The app is available for free on Google Play and the iTunes App Store, or follow this link: http://www.ag.ndsu.edu/extension/apps
