METHODOLOGICAL INFORMATION



1. Description of methods used for collection/generation of data: 


Fungicide data for the growing season and costings  were obtained from the participating farms at the end of the season. On receipt of the results from the growers, fungicide spray schedules of both prediction system and routine spray programme were analysed for the number of sprays, the active ingredients (mode of action) used, and spray intervals.



2. Methods for processing the data: 


Cost-benefit analyses were calculated at the end of the season based on fungicide cost and associated labour cost. The price per hectare of each fungicide was calculated. The sum of the cost of all fungicide sprays was determined to give the total fungicide cost per hectare for the season. Indicative labour cost for a single fungicide application was £27.50 per hectare and multiplied by the total number of sprays. The total cost of fungicides per hectare plus the total labour cost gave a total cost for fungicide applications per hectare for the season. The total cost calculated when guided by the prediction system was compared to the total cost of following a routine spray programme. The average cost of a single fungicide application per hectare (fungicide plus labour) was calculated and multiplied by the number of sprays done when following a routine spray programme.
