Remember, no-tilling will conserve much needed moisture that may prove more beneficial than grasshopper control. Three main species are typically the most numerous and damaging. The red-legged grasshopper is approximately one inch long when fully grown. Red-legs are fond of roadside plants, forage legumes and soybeans. They can feed on soybean leaves and pods allowing molds to destroy the beans.
Migratory grasshoppers are slightly larger and difficult to distinguish from the red-legged.
They are considered more damaging since they feed on most grasses and cultivated crops. It will live up to its name by flying many miles to find food. It is easy to identify by its size, color and the black chevron shaped markings on its large jumping legs. Differential grasshoppers are well adapted to feeding on cultivated crops and are also good fliers. Size and age of grasshoppers make a big difference in the effectiveness of control.
