Soil Insects: Application volumes for soil insects (African Black Beetle, Argentinian Scarab, June Beetle, Argentine Stem Weevil and Billbug) should be as high as possible (700 to 1000 L/ha) to ensure placement close to the soils surface. Use nozzles that produce very coarse to extremely coarse droplets (eg Air Induction 08 nozzles). Preferably spray onto wet or dewy turf. Irrigate with at least 3 mm of water commencing within 1 hour of application.
Surface Insects: Application volume for leaf and crown feeding insects (Argentine Stem Weevil, Cutworm and Armyworm) should be adequate to ensure thorough and even coverage of the turf leaves and penetration to the crowns. Total application volume should be 300 to 500 L/ha. Use coarse droplets (eg Air Induction flat fan 025 to 04 nozzles). In higher cut turf (≥15 mm) a significant spray shielding effect can occur, impacting negatively on spray penetration and even coverage at low application volumes.
