the milk + water solution works for my tomato plants.
I spray from top to the bottom of the plant, even the stem, both side of the leaves, also I rub the powder off when I spray the milk+water solution. like giving the plant a shower.
I did it at the morning so the sun can dry the solution. It is important to put the plant under the sun after the "shower".
