Posted on: July 25, 2024 by Tasha Stanzak
• This week we received traps from 58 of the 58 fields that we are monitoring.
• We captured a total of 30 psyllids across 14 fields.
• Captures were from the following counties: Payette, Canyon, Gooding, Twin Falls, Minidoka, and Bingham.
• None of the psyllids collected last week tested positive for Lso.
Psyllid captures continue to be moderate. Captures this week were only slightly higher than what we found at this time over the last two years. Captures in the Treasure Valley and Upper Snake were similar to last week; captures in the Magic Valley ticked up only slightly relative to last week. We have captured a total of only 3 Lso-positive psyllids so far, which is lower than the Lso incidence we found at this time over the last few years. Typically we find the highest incidence of Lso in psyllids early during the season, so this low incidence so far is a good sign that overall Lso incidence for this season may be low.
Nevertheless, we urge growers across the state to have their IPM programs in place. More information on management can be found here:

• This week we received traps from 57 of the 58 fields that we are monitoring.
• We captured a total of 14 psyllids across 11 fields.
• Captures were from the following counties: Canyon (2 fields), Owyhee, Jerome (2 fields), Twin Falls (4 fields), Cassia, and Bingham.
• One more psyllid collected last week in Twin Falls County tested positive for Lso.
Psyllid captures have been ticking down slightly over the last two weeks. Captures this week were similar to what we found at this time over the last two years. So, after seeing moderately high captures at the start of the monitoring season, we are now seeing relatively low captures. We have captured a total of 3 Lso-positive psyllids so far, which is lower than the Lso incidence we found at this time over the last few years.
Nevertheless, we urge growers across the state to have their IPM programs in place. More information on management can be found here: https://www.uidaho.edu/extension/ipm/ag-pests/arthropods/psyllids

Cercospora Leaf Spot in Sugarbeet
Sugarbeets All Locations
Cercospor Leaf Spot
Posted on: July 12, 2024 by Oliver Never
Sugarbeets - Treasure Valley, Western Magic Valley
University of Idaho and Amalgamated Sugar Company personnel have identified Cercospora leaf spot in fields near Parma ID, Wilder ID, and Glenns Ferry ID. Incidence is still low, however, most fields have closed rows, Cercospora spores have been detected in spore traps deployed in the Treasure Valley, and environmental conditions have been conducive for infection for a couple of weeks now.
If fungicide applications have not yet occurred, we strongly encourage everyone to start spraying against Cercospora leaf spot.
Several fungicides are available but be aware of multiple fungicide-resistant strains of Cercospora. Depending on the disease pressure and chemistry used, applications with different chemistries should be repeated every 14 days. Using a protectant such as copper products, EBDCs, or hydrogen peroxide with every spray is strongly recommended.[https://www.srcoop.com/articles/2024_Fungicide_Recommendations.pdf ]
Contact your crop consultant from the Amalgamated Sugar Company to discuss suitable fungicides for your area, to report a loss of fungicide efficacy, or if you have any questions.
