Effectiveness of sprays is commonly inadequate. The public is concerned with fungicide residues on the foliage and especially the fruit. Although fungicides are commonly used to control B. cinerea , they are not always environmentally friendly. Excess fungicide usage can get into the environment. Some problems include drift, leaching, and run-off.
Drift occurs during windy conditions.
Spray is carried out of the field into other fields, roadways, houses, etc. Leaching occurs when fungicides are removed from the soil by percolating water. If the fungicide is applied to a wet soil, run off can occur. Water tables, streams, and other water sources can become polluted as a result of excess fungicide run off. Control of most Botrytis depends mainly on fungicides.
