**~TREE AND SHRUB SPRAYING PROGRAM**


DORMANT OIL This is a dormant spray that must be done before active growth starts and really before any buds "swell." It is best to do this in February, but any time from December through mid March is OK. The temperature is also important – it should be between 32-70 degrees for 24 hours after spraying. This dormant oil spray is supposed to smother any eggs laid the previous season and may work on some small, soft-bodied insects as well. Our primary concern here is with the various types of scale insects, which are very difficult to control later in the year. This spray will also help some with aphids, lace bugs, and mites, ect. But these insects are fairly easily controlled with conventional insecticides. It is important with this spray to make sure you get the tops of limbs and crotches too. Hit List: The following plants should be sprayed: Azaleas Pyracantha Rhododendron Mugho Pine Quince Spruces- except Blue Spruce! Cotoneaters Pieris Japonica Burning Bush Hawthorne Euonynous White Pines- up to 16 feet only Oaks Crabapple Check List: Inspect these plants before spraying. If you find problems on a few of one species, and there are a lot of that species, then spray all of them. Also, if you know of a history of problems with scale, mite, or lace bugs, then include these plants whether any are visible or not. Pines- other than White Pines and White Pines taller than 16 feet tall. Junipers – all type and sizes Hemlocks Tulip (Yellow) Poplar Magnolias Lidens Spiraea Ash Honey Locust Arborvita Special Note: DO NOT SPRAY BLUE SPRUCE OR MAPLES- DAMAGE COULD RESULT! Late spring is when many insects get into full swing. Some of these insects are rapid breeders, and can go from a few hard to see individuals to heavy infestation in a very shot time. It is therefore important to look closely for known troublemakers (lace bugs, mites, aphids) that might be hard to see. Lace bugs and mites start early and can build up a head steam. If not checked in the early stages, they can be severe by the time of the next round. Azaleas Pyracantha Rhododendron Mugho Pine Euonymous Spruces Quince Dwarf Alberts Spruc Cotoneasters Pieris Japonica Boxwood Yucca American Holly (Not Fosters and Shrubs White Pines- up to 16 feet tall Check List: Inspect these plants before spraying. If you find problems on a few of one species, and there are a lot of the species, then spray all of them. Crabapples – Aphids Pears Pines – Other that White Pines and White Pines taller than 16 feet Birches – Aphids, Worms Willows Sycamore – Lace Bugs Spiraea _ Aphids Mountain Ash Barberry – Aphids Junipers – All types & sizes Hawthorne Hemlocks – Mites Arborvita – Mites Plums "Snow on the Mountain" – Groutweed Ash – Aphids, Lace Bugs Elm Burning Bush Lindens Fir Tulip Poplar – Aphids Honey Locust – Aphids, Mites Kwanzan Cherry Special Note: Be sure to hit all Azaleas. Early summer is when many insects get into full swing. Some of these insects are rapid breeders, and can go from a few hard to see individuals to heavy infestation in a very short period of time. It is therefore important to look closely for known troublemakers (lace bugs, mites, and immature bagworms) that might be hard to see. Bagworms usually start about June 15th and Japanese Beetles around the end of June. Lace bugs and mites are always with us. In addition to the plants listed below, check any and all plants that look sparse or don't have good color or vigor. There may be something-weird going on. Hit List: The following plants should all be sprayed: Azaleas Spruce – all kinds Rhododendron Pieris Japonica Quince Hawthorne Junipers- all types and sizes "Snow on the Mountain" – goutweed Burning Bushes- mite and scale Yucca Hemlocks White Pines – up to 16 feet tall Cotoneasters Fir Pyracantha Tulip Poplar Arborvita Purpleleaf Plum Mugho Pine Check List: Inspect these plants before spraying. If you find problems on a few of one species, and there are a lot of that species, then spray all of them. During Japanese Beetle season, spray any 'd items. Crabapples – aphids, bagworms Ash – lace bugs, aphids Pears Elms Willows Boston Ivy Honey Locust – Honey locust plant bugs Kwanzan Cherry Spirea – aphids Barberry – aphids Lindens Holly Shrubs - mites Pines – other than White pines and white pines taller than 16 feet. Birches – aphids, Japanese beetles, bag worms Honey Locust – Honey locust plant bugs By late summer* most insect problems should have surfaced and been obvious by now, and hopefully they have been successfully treated by now. If not they are probably some sorry looking plants. Some insects are prolific breeders and have very short breeding cycles. This means that If only 2 mites survived from a previous spray (1 male & 1 female), they would start laying eggs immediately and have thousands of offspring in no time at all. Meanwhile, their offspring are doing the same thing. Aphids and lace bugs also fall in this category. It won't take long for any of these to build up a sizeable population. If there has been any problem with these pests, then additional spraying on R4 is warranted – whether or not you see any live ones or not. This is probably the prime focus of R4 – to make sure any earlier problems are put to rest. On the other hand, bugs that have but one generation per year, such as bagworms, do not have this ability to regroup and come on again. Japanese Beetles should be pretty much done with by now and are not worth worrying about. Bagworms are close to the end of their feeding cycle and will become very hard to kill. If you can't see them feeding from the top of the bag – then don't bother treating. Any Burning Bushes with signs of any mite damage should be treated. Hit List: The following plants should all be sprayed: Azaleas "Snow on the Mountain" – goutweed Mugo Pine Yucca Cotoneasters Burning Bush – with any history of mites Pyracantha CheckList: Inspect these plants before spraying. If you find problems on a few of the species, and there are a lot of that species, then spray all of them.
