Corn Rootworm Management for 2018

Corn growers have come to expect some rootworm damage, but University of Illinois entomologists say putting management plans in place now could help growers avoid major losses.

Scientists Engineer Crops to Conserve Water and Resist Drought

For the first time, scientists have improved how a crop uses water by 25 percent without compromising yield.

Research Finds Wind Farms Positively Impact Crops

Iowa State University researchers have found that wind turbines located in agricultural fields are a plus for the crops growing around them.

Fall Noxious Weed Control

This fall most areas are good for fall weed control, but there will also be some areas that it may not be the best.

Fall weed control can give the best weed control but it also can be a poor time. If the noxious weeds were sprayed or clipped earlier this summer and there is good we

Issues as Harvest Approaches

It is looking like at least some harvest surprises may be positive after an up-and-down 2017 season in Illinois. The September 1 yield predictions released by the USDA this week are for Illinois corn yield to average 189 bushels per acre, up a bushel from the August 1 estimate. The soybean yield

Grassland Management Do’s and Don’ts

This is the first in a series of iGrow articles that will be dedicated to the issues and questions we receive related to establishing, re-establishing, and maintaining grass-based plantings for grazing, hay, wildlife, and recreation. This series will attempt to address the issues related to grass

Reducing Spread of Herbicide-resistant Weed Seed During Harvest and Tillage Operations

Herbicide-resistant weeds such as Palmer amaranth, waterhemp and horseweed (marestail) are spreading, increasing weed control costs and yield losses in soybeans. Because of this, producers need to take action to prevent or reduce the spread of these weeds. Combines, tractors and tillage equipment ha

Online Tool to Help Farmers Make Precision Decisions

An innovative online tool developed by a Purdue University engineering professor will allow farmers to process data collected from their fields without requiring them to share it with third-party companies.
“The Purdue Agricultural Data Engine (PADE) empowers farmers to derive value

Reducing Soybean Harvest Losses in 2017

Average soybean harvest losses range from one to two bushels per acre under normal conditions. However, harvest losses can increase significantly when harvesting tall, lodged plants or short, drought-stressed plants. Due to the variable distribution of precipitation across the state this summer,

Now is the Time to Scout for Palmer Amaranth

Now is the time of year to be looking for palmer.

Palmer amaranth is in the pigweed family and has a lot of close relatives that can be confused with it. Common waterhemp is the one that is most commonly confused with palmer. We also have spiny pigweed, tumble pigweed, smooth pigwe

Soybean Rust Develops ‘Rolling’ Epidemics as Spores Travel North

Although Midwestern soybean growers have yet to experience the brunt of soybean rust, growers in the southern United States are very familiar with the disease. Every year, the fungus slowly moves northward from its winter home in southern Florida and the Gulf Coast states, and eventually reaches

Check Labels for Pre-harvest Intervals

The pre-harvest interval (PHI) on a pesticide label is a time period following a pesticide application when a crop must stay in the application site and cannot be removed from there. Brokers, co-ops and other receivers of commodities for processing inspect producer’s pesticide application r

Understanding Growing Degree Days

Growing degree days (GGDs), while not perfect, are a more reliable method of predicting crop and insect development than calendar days. Differing threshold temperatures and beginning accumulation dates are used to determine accumulated heat units for different crops. For example, a cool-season cr

Tips for Conducting End of Season Corn Stalk Nitrate Test

The end of season corn stalk nitrate test is one of the few diagnostic tools available to determine if excess nitrogen was applied to corn. The methodology and interpretation of this test were highlighted in previous Michigan State University Extension articles: “End of season corn stalk nitra

Harnessing Rich Satellite Data to Estimate Crop Yield

Without advanced sensing technology, humans see only a small portion of the entire electromagnetic spectrum. Satellites see the full range—from high-energy gamma rays, to visible, infrared, and low-energy microwaves. The images and data they collect can be used to solve complex problems. Fo

Seeing Dead Soybean Plants in a Circular Pattern? Could Be Due to Lightning

Lightning Strikes in Soybeans
What are the odds that a soybean plant can be killed by lightning? Very low! In a recent ten year period, eastern South Dakota had an average of one to two strikes per square kilometer, per year. While quite uncommon for lightning to damage ro

What to Do With All the Leaves

The fall foliage show of reds, yellows, and golds will be beginning shortly, and will be finishing up before we know it. That one good freeze up north will take care of any more fall color as the leaves come down, left in the landscape and on the lawn.

If you are out in the countr

Give Your Soil a Check-up This Fall

Soil testing is a quick and easy task that has many benefits for anyone growing plants outdoors. By conducting a soil test, you can learn your soil’s pH and its nutrient profile.

“Conducting a soil test is good for both your wallet and the environment. By knowing what t

Are Bean Leaf Beetles Chewing Holes in Your Soybean Leaves?

Bean Leaf Beetles
In June, we discussed how we were observing quite a few bean leaf beetles in the Southeast Region of the state. Now, as we enter August, we are again observing an uptick in bean leaf beetle numbers. Why might this be happening? It is because bean leaf bee

Understand Safety When Dealing With Hydrogen Sulfide

The risks of hydrogen sulfide in swine operations have been known for years, but beef operators also need to be aware of the dangers this gas can pose. Increasing this awareness led Dan Andersen, assistant professor and agricultural engineering specialist with Iowa State University Extension and

Cover Crops After Small Grains

Due to drier weather conditions small grain harvests are well ahead of average in some Regions of South Dakota. According to USDA- NASS report published on July 24th, 72% of winter wheat was harvested in the state, while spring wheat and oat harvest acres were 28% and 36% respectively.

New System Could Remove Two Water Pollutants From Ag Fields

Algae blooms in the Gulf of Mexico use up the majority of the oxygen in the water, leading to massive “dead zones” that cannot support fish or other wildlife. The culprit? Nitrate, running off agricultural fields through tile drainage systems. But nitrate is only part of the problem. Alg

Experts Discuss the Future of Drones, Robotics in Agriculture

Unmanned aerial vehicles (UAV) and other robotic vehicles are no longer seen as toys for hobbyists, but are becoming an important tool for the future of agriculture. But many people still have questions about the safety of drones, about how farmers are using UAV on their farms, and what kinds of

Corn Disease Management Decisions

Factors that are likely to increase a return on a foliar fungicide investment include a history of disease, tight rotations, use of a susceptible hybrid, disease pressure at tasseling and weather conditions at tasseling and during grain fill.

Foliar disease management

A Five-Step Approach to Alleviating Farm Stress

Farm stressors can come from many directions including the agricultural system, farm and family finances, mental and physical health challenges, and relationship difficulties. A healthy response to these challenges involves paying attention to the stressors within all of these areas and determining
