Prevention and Control : implant repellent varieties and space plants properly so they receive adequate light and strain circulation . Always water from below , keeping water off the foliage . This is paramount for rose . Go easy on the nitrogen fertilizer . implement fungicides allot to recording label directions before job becomes severe and postdate direction exactly , not lack any call for treatments .
