After spraying I found a lot of white undissolved white powder at the bottom of the sprayer, no brown color powder just white.
Prime Source Chlorothalonil 82.5DF Select Fungicide is a dry flowable concentrate, so it is important to mix the product well while mixing and agitate during spraying to insure an even application. If the spray is allowed to settle, then some of the carrier and/or active ingredient may settle in the tank.
Per the product label: Slowly invert container several times to assure uniform mixture. Measure the required amount of Prime Source Chlorothalonil 82.5DF Select Fungicide and pour into the spray tank during filling. Keep agitator running when filling spray tank and during spray operations.
