3. Spread The Disease Ex On The Grass

You will now need to spread the Disease Ex on the grass as soon as you have filled the spreader. You can disperse the Disease Ex in two stages if you want.

To begin, activate the edge guard and move it around the perimeter of the outside boundary.

Next, deactivate the edge guard and then begin spreading the product inside.

To completely cover the entire yard, you can walk the rows with the machine spreader following any of these two approaches:

  1. When pushing from one row to the next while utilizing a spreader, the distance between the spreader and the wheel tracks should be approximately five feet. It applies to a broadcast or rotary spreader. Moreover, a broadcast spreader disperses its coverage to a far larger area. 
  2. If, on the other hand, you are operating a drop spreader, you should stride the spreader by creating rows beginning at the place where the last row ended. However, a drop spreader doesn't spread very far.

4. Remove Products Away From Any Hard Surface

It should be no surprise that the Disease Ex will come to the surface edge of the yard in some capacity.

So, after you have finished filling the lawn and notice some Disease Ex granules, it would be best to sweep them back to the grass.

The action of the fungicide can control the lawn fungus for as long as four weeks if you administer it systemically.

Do You Need To Water The Lawn After Applying Disease Ex?

Yes! You need to water your lawn about 15 minutes after applying Disease Ex to activate it.

So, ensure your grass is dry before applying and wait to water in if necessary.

Additionally, you may need to increase the rate at which you can apply them.

Lastly, it would help if you remembered that Scotts Disease Ex manufacturer highly suggests avoiding spreading more than 37 pounds of this fungicide per 1,000 square feet over a year.  

Can You Immediately Apply Fertilizer After Using Disease Ex?

Waiting for at least two days is ideal before you can freely apply fertilizer to your grass.
