I live in an area of south Fargo that is under residential development. There are very few homes in my part of town and plenty of weeds along recently constructed roads. I noticed a group of people harvesting lambsquarter leaves recently. I was surprised and went to the internet to investigate lambsquarters as a source of food for human consumption.
Last week I walked a sugarbeet field with nearly 100% stand loss on the low organic matter, eroded, higher elevation areas of the field.
Question: In this area of the state soil pH is 5.4-6.0 and organic matter is 3.2-3.5%. Some growers are planting barley on sunflower stalks treated the prior year with Beyond herbicide at 4 fl oz/A.
HSMOC Adjuvants – More Questions
I have been getting many questions about the use HSMOC adjuvants. These questions show the confusion about use and function of this adjuvant type.
I have already referred to plant analysis as a tool that growers/crop consultants can use to better diagnose nutritional problems suspected from symptoms observed in the field.
A majority of the state received rainfall during the last week. Specifically, areas south of I-94 have endured frequent rain events that have contributed to an elevated scab risk.
The IPM survey scouts visited 83 wheat fields and 38 barley fields during the week of June 15-19.
Timing. Application timing is often more important than fungicide selection. Targeting the early bloom stages is ideal (commonly 20%)
Flowering canola in some of the state is currently in moderate to high risk for sclerotinia infection. If daytime highs remain are cool to moderate (60’s – 70’s) and canopy moisture is high, a fungicide application could be warranted.
On June 19th the Sclerotinia risk map and calculator (www.ag.ndsu.edu/sclerotinia) became active for the 2015 season.
Sugarbeet Crop Update
Samples have been sent in that express metribuzin damage in potato leaves.
With the recent heat, corn is starting to green up and its growth is starting to accelerate.
In my travels in Cass County this week, I noticed a fair amount of lodging of small grains as a result of the heavy rains and fierce winds that moved through the area.
