“…The dependent variable, number of events attended, has reported values of 0 to 3 and ≥4. As all responses were not strictly numerical, but ordinal (i.e., “4 and above” is not strictly a number), ordered regression was used (Jussaume Jr et al 2022; Llewellyn, et al 2009). This regression included both respondents that attended and did not attend Extension events.…”

Data from a national survey of 348 U.S. sports field managers were used to examine the effects of participation in Cooperative Extension events on the adoption of turfgrass weed management practices. Of the respondents, 94% attended at least one event in the previous three years. Of this 94%, 97% reported adopting at least one practice as a result of knowledge gained at an Extension turfgrass event. Half of the respondents adopted four or more practices; a third adopted five or more practices. Non-chemical, cultural practices were the most-adopted practices (65% of respondents). Multiple regression analysis was used to examine factors explaining practice adoption and Extension event attendance. Compared to attending one event, attending three events increased total adoption by an average of one practice. Attending four or more events increased total adoption by two practices. Attending four or more events (compared to one event) increased the odds of adopting six individual practices by 3- to 6-fold, depending on the practice. This suggests practice adoption could be enhanced by encouraging repeat attendance among past Extension event attendees. Manager experience was a statistically significant predictor of the number of Extension events attended, but a poor direct predictor of practice adoption. Experience does not appear to increase adoption directly, but indirectly, via its impact on Extension event attendance. In addition to questions about weed management generally, the survey asked questions about annual bluegrass management, specifically. Respondents were asked to rank seven sources of information for their helpfulness in managing annual bluegrass. There was no single dominant information source, but Extension was ranked as the most helpful more than any other source (by 22% of the respondents) and was ranked among the top three by 53%, closely behind field representative/local distributor sources at 54%.

“…Responses to each survey question were modeled with a linear regression using the GLM procedure in SAS software v.9.4 (Statistical Analysis System, SAS Institute, Inc., Cary, NC) to determine whether the independent variables were significant predictors of the dependent variables (question responses; α ≤ 0.05, where the independent variable for the 2019 survey questions was stakeholders and the independent variables for the 2020 survey were crop, region, and stakeholders. This method of analyzing categorical survey data has been used for previous surveys (Jussaume et al 2021…”

Surveying stakeholder’s perception of glufosinate and use in North Carolina

et al. 2022

Glufosinate is among the few remaining effective herbicides for postemergence weed control in North Carolina crops. The evolution of glufosinate resistance in key weeds is currently not widespread in North Carolina but to better assess the current status of glufosinate effectiveness, surveys were distributed at extension meetings in 2019 and 2020. The surveys were designed to provide information about North Carolina farmers’ perception of and use of glufosinate. Many North Carolina farmers (≥26%) apply glufosinate at the correct timing (5-10 cm weeds). In addition to applying glufosinate at the correct timing, North Carolina farmers (≥22%) are applying glufosinate as a complementary herbicide to other efficacious herbicides and to control herbicide-resistant weeds, suggesting glufosinate is part of a diverse chemical weed management plan. Conversely, survey findings indicated some North Carolina farmers (13 to 17%) rely exclusively on glufosinate for weed control. Additionally, North Carolina farmers (28 to 30%) reported glufosinate control failures and control failures were observed on several weed species in corn, cotton, and soybean. The results of the survey suggest that most North Carolina farmers are currently stewarding glufosinate but also support the need for extension personnel to keep educating farmers on how to correctly use glufosinate to delay the evolution of glufosinate-resistant weeds. Yearly surveys should be distributed to monitor where glufosinate control failures occur and the weed species not being controlled.

“…The demand for reducing both selective and non-selective herbicides will increase the complexity of farm management and decision-making (Rossi et al, 2012;Jussaume et al, 2022) for perennial weed management in conservation and conventional farming. However, as expected and already described by other authors, perennial weed control is a major concern for organic farmers (Turner et al, 2007;Melander et al, 2012;Brandsaeter et al, 2020).…”

European farmers are required to follow the transition towards sustainable agriculture and food systems. Perennial weed management without chemical herbicides and inversion tillage is challenging farmers. Questions arise to cope with these spreading weeds. Our study focuses on farmers’ perceptions and experiences of perennial weeds and their control in Northern France and Eastern Germany. A survey was developed to explore the situation regarding present concerns and future problems for perennial weed control. The survey conducted from winter 2020/21 to spring 2021 targeted conventional, conservation and organic farms. We found a high level of awareness for perennial weeds. On average, 80.0% of Northern French farmers and 65.9% of Eastern German farmers revealed present concerns about perennial weeds. Both, Northern French and Eastern German farmers perceived perennial weeds are more damaging to crop production than other pests. In both regions, the farmers considered Cirsium arvense (L.) Scop. as the most important perennial weed. While the majority of the Eastern German farmers observed field infestations of Elymus repens (L.) Gould, Northern French farmers more often reported Sonchus arvensis L. infestations. More than 50% of the farmers stated Rumex spp. infestations in Northern France and Eastern Germany. Interestingly, Eastern German farmers are more concerned about future perennial weed problems than Northern French farmers. The reasons for farmer’s future concerns are probably connected to the farming system. In both regions, conservation and conventional farmers heavily rely on herbicides for perennial weed control, however, more farms used the active ingredient glyphosate in Eastern Germany. Nonetheless, perennial weed control is a major concern for organic farmers in both regions. We conclude that optimizing and integrating non-chemical alternatives is promising in all farming systems. Research activities are required to provide farmers and extension services with novel and profitable perennial weed management practices.
