Farmers must use Domestic pesticide products in Class D to manage weeds, insects and plant diseases affecting lawns and gardens around their home. Before using a pesticide, farmers should consider using alternative control methods such as cutting/mowing of vegetation. Farmers are not allowed to use Class B or C pesticides for cosmetic purposes such as for maintaining lawns and gardens around the farm house, vegetation control on paths, driveways and parking areas which are not part of an agricultural operation. Class D pesticides are available for purchase from home and garden retail stores.
