The Northwest Plains Integrated Pest Management Program is an educational program designed to promote a pest management strategy that will meet an individual’s production goals in the most economically and environmentally sound manner possible. Integrated Pest Management (IPM) is a systematic, information-intensive approach which depends on an understanding of the entire production system. It strives to use several complimentary tactics or control methods to manage pests which makes the system more stable and subject to fewer production risks. Response The Northwest Plains Integrated Pest Management Program is directed by a program area committee consisting of six individuals including agriculture producers, consultants, and agriculture businessmen. The committee actively participates in the identification of the targeted audience, planning, and implementation of the program. Seventeen Bailey and Parmer County producers actively participated in the scouting and applied research program components and many more participated in other mechanisms. Educational activities included: • Weekly field visits (50 fields) using electronic data collection methods via cellular phones with internet access; a report generator was developed to create pest management reports. The basis for the system is Google Docs and Google forms • Information gathered on these visits were delivered and interpreted to the individual producers via a scouting report • Scouting reports were distributed electronically or regular mail and in person, at site, or by phone • Pest management plans were developed and implemented based on these consultations • 21 local and area wide applied research and result demonstration projects initiated • Northwest Plains Pest Management News (15 issues, 465 individuals/issue, 3 websites) • Weekly radio show on Fox Talk 950, Lubbock • Group meetings and newspaper articles were used to distribute educational information area wide; 16 presentations at producer and professional meetings • 17 CEUs offered • 8 published abstracts, Extension publications, posters, and Fact Sheets Educational programs of the Texas AgriLife Extension Service are open to all people without regard to race, color, sex, disability, religion, age, or national origin. The Texas A&M University System, U.S. Department of Agriculture, and the County Commissioners Courts of Texas Cooperating 1 AgriLifeExtension.tamu.edu Results Retrospective post evaluation instruments were administered to clientele to determine the relevance, quality and value of the Northwest Plains IPM program. The survey was completed by 46 producers, consultants, ag retailers and ag industry representatives who were either directly or indirectly involved in the Northwest Plains IPM Program. Those producers which answered acreage questions reported 31,036 acres of crop production. • Survey responses show that clientele value pest management information and unbiased research provided by the NWP IPM Program; the following charts summarize those responses. IPM Information Unbiased Research 3% 5% No Value No Value 51% 46% Somewhat Valuable 54% 41% Somewhat Valuable Valuable Valuable Very Valuable Very Valuable • Production technologies are more readily adopted based on one’s ability to observe them in research and demonstrations under local growing conditions. Agreement rating 4.6 out of 5 possible. • 95% of respondents state that Integrated Pest Management reduces risks associated with crop production • 95% of respondents state that Integrated Pest Management maintains or increases yields while reducing input costs resulting in increased net profits • The AgriLife Extension IPM Program works with growers and consultants to develop, promote and implement pest management strategies which reduce the use of pesticides. Eighty seven percent (87%) of clientele indicate that IPM program educational activities have resulted in reduced pesticide use by an average of 22.1% in recent years. • If 15% of the 569,700 acres of cropland in the Northwest Plains eliminated only one pesticide application savings to producers would be $1.03 million. • The IPM Program works to improve clientele awareness of Integrated Pest Management issues; the following chart summarizes survey responses documenting improvement levels Appropriate IPM Tactics and Timing Pest Treatment Thresholds Impact of Natural Enemies Pest Pressure 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% No Improvement Improvement Significant Improvement 2 • Producers who responded to the survey indicate that they are likely to adopt Extension best management practices consistent with a sound IPM Program as shown below Practice Will Not Undecided Probably Will Definitely Will Manage pests based on IPM Principals 7% 7% 47% 40% Utilize established economic / action 0% 0% 53% 47% thresholds Adopt pesticides and/or management 0% 13% 40% 47% options based on Extension testing Adopt varieties/hybrids based on 0% 13% 27% 60% Extension research • In an attempt to valuate the IPM Program across various crops, producers were asked to estimate the value/acre the IPM Program has had in recent years on their farms. The following chart is a graphical representation of their responses. $50.00 $40.00 $30.00 $48.46 $40.00 $42.50 $20.00 $33.46 $10.00 $- Cotton Corn Grain Wheat Sorghum • The average estimated total Extension IPM Program value provided by survey respondents in $ per acre considering all crops and educational activities is $61.82/acre Summary It is apparent that the Northwest Plains IPM Program is not only a valuable program to Northwest Plains agriculture but is an essential part
