What is eating my apple blossoms?

Hi, I live in Bismarck, and just noticed that some kind of insect is eating the blossoms on my apple trees. It seems to be worst on my Honeycrisp tree, which has several clusters of blossoms. Only one cluster is developing normally, and the others seem to have the insides eaten from each blossom. I’ve noticed a couple of tiny extremely mobile insects in the affected blossoms - they are maybe 1-2 mm long, and very hard to see. I have two other apple trees about 100 ft away that are less affected. There is a Sweet 16 that is in full bloom and unaffected, and a snow Sweet that is slightly affected. I also have a cherry and plum, neither of which seem to be affected. I’ve attached a photo of an affected blossom cluster. Do you know what this is, and how to treat the tree? Thanks!

Sick Colorado Blue Spruce

Hi we live in Richland county, ND. We have around 300 Colorado Blue Spruce trees that 3 years ago were very healthy and green. The last 2 years we have noticed there needles have thined down tremendously. We have even lost 25 this spring. What could be going on? See attached photos. Thank you. Brandi Anderson

When is a good time to apply a pre-emergent for crabgrass? Does the soil temperature need to be stable at 55 degrees before the pre-emergent is applied? I think according to DAWN the soil temperature in Jamestown is about 46 degrees.

Thank you

temporary ryegrass lawn

Greetings from western ND!
Last year I used glyposate to dessicate my farmhouse lawn and then tilled it. After reading your publication on home lawn care (H1311 revised) I decided to wait till this fall to plant it. I would plant a temporary stand of perennial ryegrass. Does it need to be covered with straw or wood chips too? Should I dessicate the perennial ryegrass before seeding the lawn this fall? What blend of grasses would you recommend for a hardy lawn in my area?
Thanks, Aber
