註釋Historically, hybrid maize in the United States was rarely sprayed with foliar fungicides, but that began to change in 2004. Fungicides are now being used in the absence of significant disease pressure. This is at odds with standard integrated pest management practices. However, growers do not typically use a given management strategy unless there is a perceived benefit. A survey was done in 2009 of maize growers and certified crop advisors across four Midwestern states (Iowa, Illinois, Ohio and Wisconsin) to better understand the values, beliefs and perceptions of those involved in making decisions on maize disease management. This article documents the survey administration, data collection and preparation for statistical analysis. A part of the survey was analyzed to build grower and crop advisor profiles. The grower population tended to be older with less formal schooling than the crop advisor population. Growers were very involved in decision-making, and often used the services of a crop advisor. Crop advisors had 91 grower clients on average, and 90% of advisors had 150 or fewer clients. Advisors with 150 or less clients were consulted on 239 maize hectares per grower on average. Growers and crop advisors interacted primarily via one-on-one meetings. Advice was provided mainly in the areas of crop production, pest management and crop nutrients. Growers owned about 50% of the land they farmed. Crop advisors were more likely to suggest different management techniques for rented land as opposed to land their clients owned, whereas growers tended to manage owned and rented land the same. On average, 89% of crop advisors took part in integrated pest management training every year.
