Weekly Crop Scout Report

Be sure to visit our website for the latest “On the Radar” crop scout report.  It’s a detailed look at what our scouts are seeing in the fields this week, and what you should be looking for to ensure the optimum growing success with your crop!

We cover everything from nematodes and other pests to corn striping caused by nutrient deficiencies. (See photo below.)  Click on June 10, 2016 Crop Scout Report.

CORNSTRIPING

Cutworms found south of Galesville

cutworms 5-20-16.jpgPlease be sure to watch your fields for cutworm activity.    We found some eating on this young field corn south of Galesville yesterday morning.   They hid just below the surface during the day.    Purdue has a nice write-up on cutworm.  Click here for more information:  https://extension.entm.purdue.edu/fieldcropsipm/insects/corn-cutworms.php

UW has another nice article on cutworm activity this spring:   http://ipcm.wisc.edu/blog/2016/05/black-cutworms-in-corn/

Please let us know if you need help looking for this pest in your corn.

 

Wireworms attacked soybean field

wireworms 5-19-16While scouting with out interns from the Galesville location yesterday we found some wireworms attacking soybeans.    Unfortunately, these soybeans were not treated with an insecticide.   Purdue has some excellent information on wireworms for your reference, for more information visit  https://extension.entm.purdue.edu/fieldcropsipm/insects/soybean-wireworms.php   

I always encourage my customers to look at treating their soybeans, especially in a cool spring, like the one we are having now.    Please consider looking at a soybean seed treatment to control this pest.   Once they are present there are not many effective rescue options available.  Please click on the link below for more information on an excellent treatment option.  Acceleron PonchoVotivo

 

 

Watch out for black cutwork feeding!

As I have been out monitoring my black cutworm pheromone traps I am seeing a spike in moth flights, which could eventually lead to serious black cutworm issues in the next following month. DATCP is projecting that May 20th will be the average date when larvae are reaching their maximum damage potential.  One black cutworm can cut down as many as 4 or 5 plants in its larval stage.

With a wide range of hosts black cutworm can be a problem not only in corn but also in soybeans, sunflowers, and other agronomic crops. When scouting be sure to pay attention to low wet areas, patches of fields that have early weed development as well as fields that use reduced tillage systems.

When scouting fields check 10 plants in 10 different areas of the field to record the percent of plants displaying feeding symptoms, if feeding is greater than 3% an insecticide treatment may be considered.

Consult your Allied Agronomy Advisor for control options if you believe you are at threshold. — Josh Johnson, Agronomist

Cutworm Already Wreaking Havoc

Cutworm in Adams countyEarlier today one of our Agronomists, Matt Selenske found some cutworm activity in a field south of Adams.   Please make sure to be out checking your fields.  This pest can be hiding just below the soil surface.  Especially during the heat of the day.  If you see damage above ground, gently scrape the top soil away to expose the pest.    If you need help checking for this pest please contact your local Allied Agronomist today.  For more information on cutwork, click on the following link:   Identification of Common Cutworm Species – Stewart – Spotlight

 

Pest Alert in Wheat!

intern Pat CauleyYesterday we took one of our Agronomy interns, Pat Cauley, to investigate a couple of wheat fields.   We found evidence of powdery mildew, a destructive fungal pathogen, and aphids.  If you are producing wheat this season please make sure to scout your fields now for any pest pressure.  If you need assistance please contact your local Allied Cooperative Agronomist.  These pests can cause damage to your wheat crop and significantly reduce yield potentials.   For more information on this powdery mildew, Powdery_Mildew_of_Wheat.
