1. Existing and future farm policy and equipment.
Existing and future farm policy will dictate the area, variety and rotation of the crops to be sprayed; different crops will have different spraying requirements, such as types of chemical, application rates and the timing of applications.
High tunnels, also referred to as “hoop houses,” are simple, plastic-covered, passive solar-heated structures in which crops are grown in the ground. High tunnels resemble greenhouses, but are less expensive to construct and maintain. Fruit and vegetable growers use them to extend the growing season and intensify production in cold climates. The advantages of growing crops in high tunnels rather than in fields are:
Why does a pesticide work well one time and not so well the next when everything seems the same? Variable weather could play a role. Or the pest could be less susceptible to the active ingredient. At other times, an inconsistent pesticide performance seems inexplicable.

Disease and insect control is a critical factor in most commercial vineyards. Whilst such control may, in some seasons, be a small proportion of crop value, there is a demand from growers for increased efficiency of spraying. Attention to detail is necessary to improve efficiency of deposition, reduce drift and increase sprayer output.
