Prevention and Control : implant repellent miscellanea and space industrial plant properly so they receive adequate visible light and air circulation . Always water from below , keeping H2O off the foliage . This is paramount for roses . Go easy on the N fertilizer . Apply fungicides according to label direction before problem becomes knockout and follow management exactly , not miss any want discussion . Sanitation is a must - clean up and take away all foliage , flowers , or debris in the fall and demolish . Pest : CaterpillarsCaterpillars are the immature kind of moths and butterflies .
