A recent article by the University of Nebraska declared hopper numbers are high. Top Hat has developed an affordable plan for rangeland grasshopper control. It is a government approved program, but unfortunately no cost share is available.
Grasshoppers are much easier to control when small so don’t hesitate; take advantage of this program with a cost under $5.

There are three stages in the grasshopper life cycle: the egg, nymph, and adult. Every species has it’s own time periods these cycles occur. Although there are many different species, the Whitewhiskered grasshopper is one of the most predominant in this area (nymph stage May thru Aug).
If control is needed in rangeland, insecticides are most effective when applied while grasshoppers are in the 3rd and 4th Nymph stage.
Whew! It’s hot, dry and a touch windy! This is a perfect combination for a spider mite infestation to occur.
Your probably thinking its too early in the year to be concerned with spider mites. Normally this would be true, but there have already been some found this year in small, one to two leaf corn.
The Banks Grass Mite over winters in the crowns of winter wheat and native grasses. As these areas dry up the spider mite must find a new source of food and the corn field is its next home.
Because of the abnormally dry spring we are experiencing this year is the reason they could become a problem so early in the growing season.
Scouting is important because it wouldn’t take long for a small colony to become a big problem. Spider mites reproduce rapidly. Mite eggs usually hatch in about three to four days. It takes about ten days after hatching before mites are mature and begin to produce eggs.
Mite infestations occurring early in the season should be scouted carefully during the rest of the season.
If the infestation reaches threshold there are several options for chemical control. Let us help you choose the right one for your field situation!
We recommend CoRon as a source of N at V-6 to V-8 and prior to tassel to increase yield potential. Current research has shown 1 pound of N from CoRon can replace 5 pounds of N from your current program.
Apply CoRon at 1-2 quarts/acre with foliar insecticides throughout the season to spoon feed Nitrogen.
