Hopper 4.0

Hopper Overview

Hopper 4.0 can be used to help determine the best course of action when dealing with grasshopper outbreaks on rangeland. Managers can use hopper to estimate public, private, or total benefits versus costs for either public, private, or cooperative rangeland grasshopper control projects. Clearly, the decision to control or not control rangeland grasshoppers is not simple. The suggestions and guidelines in hopper will help managers avoid blunders, mistakes, and errors-and will help support rational pest management on public and private rangelands. Users should compare recommended treatments with other options developed since the program was written, such as RAATs and Dimilin. Not all treatment options listed in Hopper are currently registered for use on rangeland. Although Hopper 4.0 is a DOS based program, it has been modified by USDA-APHIS-PPQ-CPHST to easily install and run on all Windows 2000 and XP machines.

HOPPER Disclaimer

HOPPER has been tested as much as possible with the available data and experts, and has performed satisfactorily.  However, the rangeland ecosystem is very complex and unpredictable.  In addition, HOPPER does not have any control over the data entered by each user.  Therefore, the results derived from HOPPER CANNOT be guaranteed.  The following disclaimer applies:

HOPPER and its associated files and documentation are distributed without any expressed or implied warranty of any kind.  The author, supplier or distributor shall not be liable for errors contained herein or for incidental or consequential damages in connection with furnishing, performance, use or misuse of these materials.

Notice

Hopper still lists Acephate as an option. However, Acephate is no longer registered for use on rangeland. Please ignore any recommendations Hopper may make for Acephate. Hopper does not list Dimilin 2L as an option. As of 2001, Dimilin is registered for use on rangeland. Hopper does not incorporate the use of Reduced Agent Area Treatments that reduce application rates, costs, and environmental concerns, while maintaining effectiveness (see RAATs Brochure).
