hello my name is Jim lose our I'm Cade and agriculture natural resources today we're talking about the issue in wabash valley area of the tulip tree popular scale the tulip tree the state tree of Indiana has been besieged in the recent weeks with the tulip tree scale and insect at over winters and because of the mild winter we had in the past winter the population is survived more than normal giving us a situation where we have a substantial amount of SAP feeding damage from this insect now the discussion today is about control methods and if the insect is of substantial numbers on the tulip poplar tree also magnolia trees will be affected by the tulip scale insect the appropriate method is that systemic insecticide and so products if you're looking at the store for product for the insecticide treatment right now what we're recommending is a systemic insecticide with the active ingredient and you'll be looking right there on the label for the product of the active ingredient and ematic culprit is the active ingredient that work that we're seeking to control the tulip tree scale so the solution as far as a drench and we're going to show and demonstrate how to operate a drench application is very simple but the first thing we have to do is know the amount of product that we need now that label would read the product label we always recommend reading product label suggests one ounce of material per inch of circumference of trees of the tree at four inches so we have to have a tape measure and we'll take a quick measurement here we look at this this is a tulip poplar at four feet will measure and calculate the measurements right after ten inch so we have a 10 inch circumference times 1 ounce per inch of growth so we'll need 10 ounces of product we need to we need to measure that 10 ounces accordingly and then put it at the gallon of water for a tree like this tree for example we would be putting in a gallon of a solution in a gallon of water and a tree that's larger we'd be mixing that solution with two gallons of water now the drench application is important that we concentrate and the systemic activity will be the material be absorbed by the roots of the tree and then taken up through the vascular system of the tree to provide control we cannot do a topical spray and spray it in sex aside right now on the scale insects and have any efficacy and so what we have to do to start out with a drench is pull back mulch make sure that we have the mulch away from the tree this is an insecticide so it's not going to damage if you have a flower bed next to the tree any kind of ornamentals like hostess for example and then we'll be applying the drip with the solution insecticide and water and we'll be flying that material and once we apply the material it probably wouldn't hurt to go ahead and do a watering we're going to ruin especially a dry conditions so that's a drench up application the systemic activity again will cause this tree roots and most of these tree roots there in the top eight inches of the top soil so they will actively move this product up through the tree out to the outer limbs and twigs and provide control then of this insect and we're not talking about maybe perfect control we're talking about suppression but the problem we're going to see with this insect with tulip tree scale is because when we get into July and August these insects will multiply and the new offspring will also begin feeding on the tree sucking sap and then the situation will be even more stressful for the tree in terms of treatment again one treatment should provide a season-long control of the insect and then hopefully in the winter of 2012 2013 will have a colder winter and will knock out a lot of this population and they won't be overwintering again with questions for this application of a systemic insecticide a person can contact the Purdue Extension vigo county office at force area code 812 4623 371
