For netting or durable equipment such as cannons or distress callers, the duration of the technique needs to be factored in as well.Ī grower can calculate cost effectiveness based on: estimate fruit prices for the year, the number of fruit days at risk, the number of pest birds you expect to determine how many days you will need bird management, what you can afford, or how detrimental the damage might be.
