but he cuts my grass very well for cheap so I'm keeping him. ==>>> OK.. you have a GRASS CUTTER.. not a landscaper.. and that is quite apparent ... if this thing is precious to you.. hire the right guy for the job ... [which might vastly destroy your lawn cutting savings.. lol ...] i admitted no palm experience.. and since many grow in sand .. i suspected it might be from a world of its own ... imidacloprid ==>> look for Bayer tree and shrub products ... you arent going to buy it straight under that name ... at bigboxstore ... and most likely nowhere REPUTABLE.. w/o a license INSURE it is labeled for said use ... apply it according to the label ... and dont mess around with it ... i never understood spraying of a systemic.. think about it.. the roots are the most efficient sucker inner [technical term there] .. so why not use them so suck it up .. besides the fact.. that spraying a plant that size is just going to waft stuff all over you.. the house.. and half way down the block.. be safe ... ken BTW.. most scale.. being that they are scaly .. get this.. are impervious to topside applications ... you have to get the product into the vital juices of the plants .. [not through the scale cover of the little sucker ... the only reason oil works on scale.. is it suffocates them.. ] .. and the best way to do that.. is thru the roots ... Here is a link that might be useful: link

Need closer up pictures. Suspect magnesium for the yellow leaves. Suggest you get a goood fertilizer wit all the trace elements.

Could be a Buddleia leaf weevil, Cleopus japonicus, considered to be a bioloogical control for the invasiveness of butterfly bushes, particularly in NZ and Australia where the plants are noxious weeds. I am not aware of them being very common in the US but perhaps they are being employed for the same purpose (Buddleia is an invasive species on the west coast and beginning to become one in other areas). And the only garden weevil I am aware of that can fly!

Black spot = fuzzy edged very black spots, some big, some little, adjacent spots grow into each other making a 'mega black spot,' leaves then yellow, and shortly fall off. Cercospora = even edged black spots with light colored, grayish to light tan centers, behaves pretty much like black spot, leaves turn yellow, then fall off. You have both. Get it under control with the Bayer fungicide for roses, in the blue bottle. Spray every 10 days, at 1.5 T/gallon of water, for three consecutive sprays, then every 2 weeks thereafter. Some years are far worse than others for fungus breakouts. To avoid having to deal with black spots and cercospora grow disease proof/highly resistant roses. Ditch the fungus prone varieties, or resign yourself to the fact that they must be sprayed regularly. Start with these varieties: Dee-Lish Quietness Wedding Bells Bliss South Africa Poseidon Moonlight Romantica Earth Angel FIji There are others....not many in the big bloomed, showy HT types, although a rose bed dedicated to the above recommendations would be a breeze to care for, and drop dead beautiful.
