Plants growing without shaded soil suffered from scald. Most scalded plants die during a few days or weeks. If you have sprinkle irrigation move the sprinkle line quickly enough the first time around so that water does not stand for more than an hour. Then, the other irrigations can allow water to stand because plants will shade the soil from direct sunlight. It seems like we get more grasshoppers during dry weather.
Early summer is the time to control grasshoppers.
Producers should not wait until they are winged and large, when control is difficult or impossible. Eight to nine adult grasshoppers per square yard should cause alarm to forage producers. That many grasshoppers can eat as much as a cow. Grasshopper problems will not go away until hard freezes come in late fall. Grasshoppers normally build up on field edges, and that is the best place to scout and treat when high numbers begin developing.
