Use of DAS

Ease of use of DAS features: Most respondents rated the use of various features of DAS as “easy” or “very easy.” Between 6% and 27% of users indicated that they were not aware of some of the DAS features. The respondents rated the various insect, disease and disorder models as “easy” or “very easy” to use.

Usefulness of DAS features: Survey respondents rated various features on DAS on average between “somewhat useful” and “very useful”. Best average ratings were given to projected model forecast with management recommendations, model charts, and the overall full WSU Spray Guide. New features, such as video tutorials, online manual, front-page stories, and iPhone version were rated on average as “somewhat useful”.

Crops used in DAS:  All crops were used in DAS by the survey respondents, most importantly apple (92%), followed by cherry (71%), pear (62%), and other stone fruit (34%).

Distribution of crop-specific information accessed by users in 2010 vs. 2008.

Models used in DAS: The most used models on DAS were codling moth (93%), fire blight (80%), western cherry fruit fly (65%), oblique-banded leafroller (64%), cherry powdery mildew (59%), and Pandemis leafroller (55%). For 62% of the survey respondents, the codling moth model was the most important model, while the fire blight model and western cherry fruit fly model were most important for 22% and 5% of the respondents, respectively.

Number of AWN stations: The number of AgWeatherNet stations used in DAS per user ranges between 1 and 134. The majority of respondents (77%) looked at 1 to 5 weather stations.

Use of Custom Weather Stations. DAS allows users to upload and use weather data from their own stations. About 28% of the respondents indicated that they had their own weather data. Respondents were then asked to rate the level of ease or difficulty in setting up their own stations within DAS.

Percentage of respondents indicating they used their own weather station.

Percieved level of difficultly in setting up and uploading user-owned weather stations.

Perceived level of difficulty in customizing with various models for their own stations.

Use of DAS. The majority of DAS users check their stations and models between once per week up to 4 to 6 times a week. When asked how sharing DAS information, the majority (68%) reported that the information is mostly for themselves, but they also share it with others.

The use of DAS resulted in an increase in the level of pest control for 56% of the respondents, reduced number of sprays (36%), reduced cost for pest management (31%). DAS helped 97% of the survey respondents to “some extent” or a “very great extent” with clarifying treatment timings, 68% with choosing chemicals for best efficacy, and 65% with clarifying management for multiple pests.

Future of WSU-DAS

Percentage of users wanting DAS to continue in the future.

Maintenance of WSU-DAS costs approximately $200,000 per year. Currently, WSU-DAS is funded mainly by WA Tree Fruit Research Commission grants, but the mission of WTFRC is not meant to support/maintain long-term projects. In light of this, users were asked if they thought WSU-DAS should continue in the future and how it should be supported.

Comparison of how 2010 and 2008 users thought DAS should be supported financially in the future.

Respondents were then asked if WSU-DAS were forced to institute a user fee, what unit of measure should the fee be based on? Most (50%) felt a flat rate user fee best and only 15.7% felt it should be per station with 34% preferring to give no answer. They were then asked how much they would be willing to pay per year.

Distribution of how DAS users felt fees should be assessed.

Distribution of the amount users would be willing to pay for DAS.

We also asked how the user’s operation would be affected if DAS was discontinued next year. The majority of survey participants indicated that the discontinuation of DAS would have “major” or “modest” impacts on the clarity of treatment timings (95%), on the improvement of the user’s overall management strategy (88%), level of pest control (76%), management for multiple pests (71%), costs for pest management (71%), the user’s number of sprays (70%), the user’s choice of chemicals for best efficacy (64%), and choice of chemicals to reduce natural enemy mortality (58%).
