Dormant spray - fruit trees

Is a dormant spray harmful to bush tits that hang out in our apple trees? We have a flock of about 30 bush tits. Could they be eating insects on our apple trees. They come to our suet block n then fly to the apple trees.

I have lettuce and kale growing near our apple trees. If I spray will it harm the lettuce and Kale?
how late can I apply a dormant spray to our apple n pear trees?
Thank you, Bernadette

Artichoke seed disinfection

I'm wondering how I'd go about disinfecting artichoke seeds. I started a handful of untreated artichoke seeds and a little less than half germinated. In two or three days, no additional seeds have germinated and maybe only half of those that did had healthy looking radicles. The remaining seeds are now showing signs of fungal growth so I imagine that I won't get any further germination. Before I start more seeds, I was hoping to treat them to prevent further fungal issues.
