    My father in law asked as he assumes this turf guy also knows landscape pests.

    I'm assuming he would like a granular type product for ease of application. First thing that comes to mind is merit or safari as a systemic.

    Any suggestions that I can pass on to get on his good side??

    Remember that Merit takes up to 45 days to go up into shrubs that are old and woody. Safari is a little faster, but does not last all season. How many plants are we talking about? Quantity needed is dependent on size and number of plants. This is not like spraying or spreading on lawns where one set dose treats an acre.

    Not sure about boxwoods, as they don't grow this far north, but for leaf miners I go to the local nursery and get a qt. bottle of Bonide and soak the roots of the infected plants according to label directions... It has worked every time I tried it...

    So he had about 15 box woods about 3 ft tall. He found a merit product by Fert i loam and did a soil drench. Not hard work but the product was only 1.5% and he was soil drenching at 3 gallons per bush. Also added some granular Fert along with it.

    Really looked easy as a possible add on for people who would be interested

    Not a bad add-on, as long as people don't go nuts and end up spraying every tree with every possible excuse, with anything and everything, whether it needs it or not...

    1 qt. of the stuff I got did a 6" dia. tree,,, twice... I mixed it up in 1 sprinkler can and went out from the trunk 6' diameter drench...
    3 gallons for a boxwood about 5 ft tall, seems excessive...
