The first twostriped adult was spotted last week near Winnett. Some adults have been reported, though they are not the more serious pest species. Populations of five to six per sweep have been counted and a particularly high population of 10 to 15 per sweep was found adjacent to cropland. As temperatures warm, grasshopper populations could move very rapidly into cropland. Spring wheat may be at particular risk this year because planting was delayed due to weather.
Adults are more difficult to control.
When using insecticides always read the label and follow directions. Because temperature relates to the growth and development of biological organisms, calculating degree days can be used to predict the presence and development of many pests and plants. This is the average daily temperature. Then take the average daily temperature minus base temperature to get degree days. Horsetail is also called scouring rush and is a herbaceous perennial which grows each year from an extensive rhizome system.
