Managing stored grain to minimize storage losses

by Phil Glogoza and Dave Nicolai, Extension Educators-Crops

When grain harvest approaches, it is time to review basic on-farm grain storage principles for maintaining quality of stored commodities. Harvest should include preparation of storage structures to receive grain. Preparation includes several practices that aid in preventing pest infestations from developing within our storage structures.


Total Tillage Solutions Field Day draws big crowd

Here is a story and video highlighting the Total Tillage Field Day held on September 4 near Appleton, MN.

written by Jonathan Eisenthal, Minnesota Cornerstone blog

About 250 farmers gathered at a farm field seven miles south of Appleton in Lac qui Parle County to see demonstrations and hear information covering the entire spectrum of tillage, from ‘biological tillage’ (letting earthworms and tillage radishes do the heavy lifting) to moldboard plowing — the most invasive technique, but still a useful tool to be applied sparingly, according to the experts.

Many corn and soybean fields in central, west central, and southwest Minnesota were affected by frost during the morning hours of September 13, 2014. As is always the case, the frost damage appears to be highly variable based on local climate conditions, crop maturity, and topographical features.

Soybean Aphid Populations mixed, Field Infestations can be quite Different

A quick survey of soybeans around the northwest MN region revealed great variability in soybean aphid populations. 

Some fields have not required treatment, many fields have been treated and are in good shape, other fields not treated may have quite variable numbers and often are related to growth stage with R3 fields still vulnerable to losses from threshold populations.

Soybean aphid thresholds demystified - a satirical examination

prepared by Bruce Potter, IPM Specialist SW MN
University of Minnesota Southwest Research and Outreach Center, Lamberton

Before anyone gets too bent out of shape over this... Yes, I know this is a stressful time for some soybean growers, most of their advisers and for aphid researchers too.   It is not illegal to apply insecticide to any population of soybean aphids as long as it is within label restrictions.  Finally, I am not the police and it's the soybean farmer's money, not mine, at risk. Insecticide resistance does tend to spread itself around though.

Based on emails and phone calls, there seem to be several economic (action) thresholds for soybean aphids in use now.

So you don't like counting aphids

Here is an overview of "Speed Scouting" for soybean aphid that was written in 2012. The information is helpful if you don't like counting aphids but still want to make an assessment of what is happening with aphids and whether treatment is economically justified.

Soybean Aphid migration, colonization and infestations underway!

Soybean aphid migration is underway in NW Minnesota. Scouting indicates winged aphids are being found in fields. In some fields, the small infested hot spots (3-4 row feet of heavily infested plants) are more readily detected.

Scouting fields needs to begin in earnest to determine where your fields are in the process. The following link will take you to a refresher on aphid biology, scouting and treatment decision making.

Preharvest Management Options for Wheat

Winter wheat, if not already there, is quickly approaching physiological maturity. The earliest seeded spring wheat is soon to follow. And thus, it is time to evaluate your pre-harvest management options. Follow this link to read a quick review of your options.

Although there are very persistent assertions, pre-harvest glyphosate - when applied according to the label - should not result in changes in grain protein. A summary of a study to debunk this myth can be found here

HRSW varieties differ for their resistance to pre-harvest sprouting. This high-temperature dormancy peaks at physiological maturity. Repeated wetting and drying of the grain in a swath or even while standing will degrade this dormancy over time. The dormancy of some varieties break down sooner than other, potentially resulting in sprout damage. Click here to look up the ratings for the current HRSW varieties. The best remedy to avoid pre-harvest sprout damage is to harvest timely, even if that means that you are above 13.5% grain moisture content

Finally, many wheat fields are showing tall off-types. Click here for the reasons tall off-types appear in spring wheat. Varieties that are notorious for off-types are Mayville, LCS Albany, and Rollag.

Soybean Aphid Scouting Reports from NW Minnesota

Soybean Fields scouted 7/14 - 22/2014
Begin scouting fields to establish where your soybean aphid field infestations are at this time. Here is a captured image from Google maps showing our first soybean field scouting reports from around the southern end of NW MN. Most of our scouting detected no infestations based on random plant selection/scouting. Aphids have been found in fields, but the numbers have been well below treatable populations.
July 17, 2014
Scouting activities did find a field (indicated by red marker) with low level of aphids on Thursday, July 17. Plants with aphids on them represented ~30% of the plants inspected (~70% had "0" aphids). When aphids were found, numbers were well below 20/plant. 

July 22, 2014
Scouting in the Underwood, MN area. Aphids were observed in fields, but the infestations were generally light. Plants with aphids present accounted for under 25% of those sampled. When aphids were found, they numbered less than 10 aphids/plant. One sampled plant had ~40 aphids; no other "hot spots" in the field were noticeable. In other words, still quiet though aphids are out there.

Fusarium Head Blight (Scab) Forecasting Models

The recent windy days and reduction in extended moisture events has reduced scab risk based on the forecasting models. However, if frequent moisture events and high relative humidity occur, scab risk will increase quickly.  

Bacterial Leaf Streak in Wheat

Prepared by Dr. Andrew Friskop, Extension Plant Pathologist, NDSU

Last week the IPM survey scouts recorded bacterial leaf streak (BLS) in a few wheat fields. Additionally, I noticed BLS showing up in one of my wheat trials on campus. Given these observations, I feel it is important to review information on BLS.

Small Grains Survey for June 9 - June 20, 2014

Crop growth stage maps from last week had fields across the NW region in the leaf to tillering stages. The map that will be published next week will show rapid progress, with fields in the joint - boot - flowering stages. The further south you go, the crop is flowering - milk stage, primarily the winter wheat.

Rolling Beans Postemergence in 2014

Rolling soybean fields prepare the field for harvesting by pushing rocks into the soil, breaking up corn rootballs, and firming/smoothing the seed bed allowing  combine heads to be run low to the ground with less risk of picking up rocks, rootballs, and dirt.

Land rolling can pose agronomic, economic, and environmental risks including plant injury/disease, soil sealing, erosion, and added expense.

Understanding the advantages and disadvantages of land rolling will help farmers decide if — and when — rolling makes sense.

Scout for Alfalfa Weevil before / after First Cut

Alfalfa weevil is a pest associated with the first cutting.The first cut for alfalfa has been well underway in west central and northwest Minnesota for the past week. Alfalfa looks very good as the cool weather allowed for significant vegetative growth. Growth stage in the region is late bud to early flower. The weevil, though, are developing at their own rate, a rate affected by temperatures.

Small Grains IPM and Crop Progress Survey to Begin in Mid May

The small grain survey will be run jointly across Minnesota and North Dakota beginning in late May. Unlike the 2012 season when the survey started when the crop was already in advanced growth stages, this year's survey should begin when the crop is young and significant pest issues won't have begun.
