Isn't it already hard to become an applicator in your state? That does not fix the combination of ignorant and stubborn teaching the new guy how to be the same way. Not saying that I am perfect. In some cases, I do not kill 100% of the weeds in the first application. But burning stripes, spots or the entire lawn out does not happen. Here, if it is not windy or raining, the temperature is pushing 90. I would not apply in the wind or rain. Lawns can tolerate the label rates of products if they are not starved, dried out or going through anything else that compromises their growth. Therefore, as the applicator, I exercise control over the water and fertilization or no deal. It is not as simple as spraying the lawn and tagging and flagging.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
