Cultural Control of Grasshoppers
Cultural control is a preventative approach to grasshopper control. Cultural methods to control grasshoppers include early seeding of crops, crop rotation, tillage, trap strips and early harvest.
Early seeded crops will withstand more grasshopper damage than younger plants not well established. Avoid seeding any crop on stubble fields with history of heavy grasshopper infestations.
Tillage prior to spring hatching controls young grasshoppers primarily by eliminating the green plants on which grasshoppers feed.
In the spring when nymphs are hatching, untilled strips of green vegetation may be used to concentrate grasshoppers in a relatively small area making insecticide treatments more efficient and economical.
Late season tillage of summer fallow discourages grasshoppers from laying eggs.
Early harvest of physiologically mature crops which are being infested with migrating grasshoppers may prove more economical than treating with an insecticide.
