Hello, I need some help identifying two/three diseases that my pear tree has. Please see attached pictures: Leaf 1: yellow spots with red dots in the the middle. I suspect it might be Pear Trellis Rust but the pics I have found on the web do not look similar. Need confirmation from the experts. Also the underside of the leaf has brown lesions along the leaf veins (see pic), is this a different disease or symptomatic of Trellis Rust. Leaf 2: Brown dots on top and underside of leaf. Looks like two different forms of scale insects. I suspect Pear Leaf Blister Mite but whats the other one? Again need confirmation. I am located in S. Ontario. I sprayed this tree with Lime Sulphur last winter and also in Spring, it has also received two sprays of Copper solution (the last spray being about 8 weeks ago). The yellow/red spots on Leaf 1 began in the last 2 weeks. If there are some other sprays I should be using (e.g. Malathion) please let me know. Thanks.
