Residual Activity	Essentially none due to adsorption of chemical to soil particles.
Unique Characteristics	Must be used with clean (non-turbid) water as the soil particles in muddy water drastically reduce the effectiveness of diquat. Apply in weather conditions that will not promote drift. For aerial application suggested conditions for good application are moderate temperatures (less than 25ºC), humidity (greater than 40%) and wind (3.6 - 10 kph). Do not apply in dead calm conditions or when temperature inversion is likely (e.g., morning or evening when warm air is rising from crop). To avoid spray drift, use flat fan or hollow cone nozzles and a pressure of 140 - 210 kPa. For aerial application point the nozzles back 130º - 180º. For further information on aerial application refer to the product label.
