Resource can help growers plan for summer spraying.. "Often the most important factor in summer weed control is getting the timing right and using a robust rate of product," Dr Hughes said... Dr Hughes said that with legal pressure on night spraying - due to the presence of surface temperature inversions - South Australian trials tested the control of 'tough weeds' in less than favourable conditions during summer daytime spraying...

robust rates of products and appropriate water rates are often more important for achieving efficacy than the nozzle type, but, correct nozzle type can widen the spray window, improve deposition and reduce drift risk... using the minimum hold (or lower limit The use of offset (angled) nozzles or twin function) in the controller can reduce this, designs can improve the evenness of but can also encourage overdosing leading deposition, provided the travel speed is not to crop damage... Other factors that are important for application include: maintaining boom height to achieve double overlap at the top of the stubble or crop canopy; when using Group i, Group M and Group A products ensure that the water quality is suitable; ensure the correct tank mixes; mixing orderfor only spray under suitable weather conditions, where daytime wind speeds are above 3km/h and away from sensitive areas and not exceeding the maximum wind speed on the product label; and do not spray if surface temperatire inversions occur...
