Constraints:
-
Easy Management
-
Retain the fungicides successfully until they have naturally degraded
-
Aesthetically pleasing
-
Be able to capture and focus the spray onto the treatment area as the spray is coming out of the dispersal machine.
-
Low cost for installation and management
Criteria:
-
Area of land 20ftx20ft = 400 ft^2
-
Scalable for 200% the current work load to accommodate vineyard growth
-
Be able to be implemented in a land space with rocky soil with 1-3ft topsoil before hitting bedrock.

Figure 1: This picture is of the spraying machine used to spray fungicide on the vines. The water/fungicide mixture is held in the yellow tank, and is blown out the side. To clean the equipment water is added to the top and the machine is run to get rid of any residual fungicide that might be left in the tank. As the water is sprayed out of the machine it spreads in a pattern that is about 7ft high and extends about 20ft out. This requires the design to include a method of collection or redirection.
Figure 2: These are pictures of the rocks found naturally in the soil. It is a composition of quartz, schist, and slate. The soil also has the characteristic of being fast draining. This will be taken into consideration for the feasibility of our design.
