29 Nov blue spruce losing needles bottom
If the inner needle browning is significant, however, a fungal disease may be the culprit. Over the past few years, many homeowners have been alarmed by what seems to be a sudden decline of their I had a Colorado blue spruce, Hopsii, and three Serbian spruce trees installed, and I am terrified this same disease will encompass these trees as well. I would like to bring samples of the spruce and Cyprus ASAP. Here is a snip-it from another "Ask an Extension Expert" question on the same topic (https://ask.extension.org/questions/117373) : A protective fungicide with the active ingredient chlorothalonil (sold as Multi- Purpose Fungicide, Daconil 2787, and others), Two-some, Spectro-90, or copper based fungicide can protect new growth and prevent new infections. Ask an Expert is made up of groups and individual experts. https://worldofgardenplants.com/trimming-bottom-branches-of-blue-spruce The two product formulations that you listed in your email are commercial formulations that are going to be very expensive and are large volumes that would be difficult to mix in small batches and fully consume.I would not necessarily focus on the particular formulation as being the "be all and end all". If something is eating the needles on your Spruce, you have Sawfly. | Ornamental Disease Facts Photo credits: Jill O’Donnell, MSU.

However, the tip die back is harder to diagnose since there seems to be no casual agent that is evident (insect or disease) There thought is that this may be environmental or abiotic(not biological). My direct email is firstname.lastname@example.org..SteveUnfortunately, both of these species are really going to be a "wait and see". This summer, the bottom 1/4 of the branches have slowly disappeared, as if they have been removed, exposing the trunk. I have attached several photos of my spruce. It was really great to speak with you this morning. It is most common in trees growing outside of their native range. Any way that you can email me a picture of the plant and a close up of a branch that is manifesting the symptoms that you are describing? Daconil is the most common fungicide found on store shelves and the most readily available. Thanks for the info and articles. If so, I can call that day to give you a time when I should arrive. I don't think drought is the issue because we have an irrigation system. I just hope we didn't permanently harm the tree. Photos 6-7. Yellow-headed sawfly are attacking spruce trees right now. June, 2011. I had a question on purchasing the proper strength of Daconil (chlorothalonil). Two possible new diseases of spruce have been seen in the Plant and Insect Diagnostic Clinic recently. Stress makes them susceptible to this canker. My direct email is email@example.com Thanks, Steve. Why are we seeing increased decline in blue spruce trees? Is this tree in danger of getting the same disease? http://extension.umd.edu/hgic/cytospora-canker-spruce, http://extension.umd.edu/hgic/topics/evergreen-needle-cast-diseases-trees. I know the tree sustained no physical damage to the trunk, from say mowing or the like, as it sits in a bed next to my deck. The key to successfully managing this disease requires that you protect new growth as it emerges. In drought-like conditions, evergreens may have trouble getting enough water to all their needles. I hope you are having an enjoyable holiday season. Would you like me to bring samples of the Colorado Spruce needles and the Cypress needles? Please call before hand. Application to large trees requires special equipment to ensure adequate coverage……. The pamphlet from original manufacturer, Syngenta, says the strength of this version was 40.4% Chlorothalonil. I hope the photos can help you with a diagnosis, and you can offer me some insight on how to proceed with protecting my other trees. If the tree’s soil is dry to the touch, give it extra water through summer’s dry spells. Well-timed sprays in the spring can control needle casting diseases if the spruce is currently managed with fungicides after the new growth has expanded to 0.5 to 2.0 inches in length. To help manage these needle cast diseases, consider better air drainage, greater planting distance between trees and better site selection. However, as 2017 was a banner year for the fungus, I commonly saw it on white spruce and even on Norway spruce, which is supposedly resistant to the disease. Yes, i will be in the morning.Thanks, Steve. It doesn't appear to have any pests. I’d greatly appreciate any advise on combatting the disease that appears to be infecting this tree. I have a dwarf blue spruce that is about 10 years old, which has begun dropping needles at an alarming rate.
