Practical Grasshopper Management Information from States and Provinces
Included below are numerous links to resources, informational guides and management publications from state cooperative extension services, universities and departments of agriculture on the management of grasshopper affecting both crops and rangeland. Information includes grasshopper cultural control methods to protect cropland using trap strips and extension publications on controlling grasshopper in cropland, rangeland, and yards and gardens. Information written for one state is typically applicable to nearby states and provinces.
