Dormant Spraying

Many fruit trees and woody ornamentals benefit from winter applications of Copper fungicides and Dormant Oil sprays. Diseases such as Peach Leaf Curl and Shothole Fungus can only be controlled with dormant applications. For many years, Killroy has included this service with most of our residential accounts. Some customers call us specifically for this service annually, as they have a large number of trees on their property.  Please contact us and we will be happy to provide you with more information and a quote for fruit tree dormant spraying.

Olive Tree Fruit Elimination

With the re-registration of Maintain CF125® plant growth regulator, we have a reliable solution for olive fruit prevention. Trees can be sprayed from late January to early April before any flower bud formation on the olive tree. The chemical causes any flowers which form in April and May to wither and fall off without setting fruit. This effectively prevents the messy problem caused by unwanted olives in late fall and into the following year, usually with 90% fruit elimination or better! The spray only works for a single season, and must be done every year. Trees under stress, radically pruned, or with sensitive plants under them may require special precautions.  Covering plants during application or hosing off the plants beneath the tree before and after the spraying will help protect them, and our service technicians will provide this service to avoid any damage to other plants. The price for the Maintain application depends on size of the tree and gallons used.  We do offer discounts for multiple trees, neighborhoods, and communities. 

Winter Weed Control

Many customers have us apply Pre-emergent Herbicides annually in winter to prevent a wide spectrum of annual weeds from becoming a fire hazard in the late spring. Gravel areas, fence lines, driveways, propane tanks, and industrial areas where weeds must be controlled are all good areas to treat. Steep slopes should be evaluated for potential erosion issues before being sprayed. Other treatment options exist for chemically mowing these areas in the spring. While not all weeds are controlled, the need for hand weeding and mechanical control can be greatly reduced.

Oak Tree Spraying

Many customers have selected Oak Trees to be treated annually in the spring to control a variety of "worms" (moth larvae) which cause a mess on decks and patios, as well as chewing leaves in heavy years. While oaks are rarely severely damaged, the cosmetic damage can last for months in years of heavy infestation. 

Other Seasonal Services
