You should also wear protective key wear when you're spraying. I learned my lesson the hard way. While praying shrubs with a fungicide, a drop got into my eye.Always always have your specs (safety glasses) on when mixing. Always. I have cheap clear ones I use when I mix. You will pour something into the tank and see that one odd drop "drip" upwards dang near to your head height. That will get you thinking. Those plops that splash back up to your face even though your are carefully pouring into your tank.
I was very painful, I tied to drive to an urgent care but had to stop and call our office send someone to pick me & get me to urgent care ASASP. Two painful days with eyepatch. Luckily, no permanent damage.
