Wind speed, the spray amplitude should also be smaller, on the contrary should be larger, generally to 3 meters to 3.5 meters appropriate. Spraying time is best selected in the morning, afternoon or cloudy, to avoid sun exposure. Ultra-low volume spray is best used in internal suction, fumigation or gastric poison.
