Introduction

Application:
Oberon
• May be applied by ground or air.
• Apply as soon as mite populations reach threshold levels. Repeat application if pest populations recover and reach
economic thresholds. A minimum interval of 7 days between applications is required.
• Thorough coverage of all plant parts is important for optimum performance. Use sufficient water volumes for
thorough coverage - i.e. minimum of 40 to 80 litres of water per acre.
• Avoid application when heavy rain is forecast.
How it Works:
Spiromesifen is in the Tetronic acid class of insecticides and works by contact, inhibiting lipid biosynthesis in the insect.
Oberon has strong adhesion to the leaf surface, and also some translaminar activity providing residual control through
contact or ingestion. Oberon has activity on all mite developmental stages. Immature mite stages tend to be more
susceptible to Oberon than adults.
Restrictions:
• Alfalfa – DO NOT exceed 3 applications per season. Keep a minimum interval of 7 days between applications.
DO NOT exceed a maximum of 1200 ml per acre of Oberon per season. Corn – DO NOT exceed 2 applications per
season. DO NOT exceed 240 mL per acre per 14 day interval. DO NOT exceed 480 mL per acre per season.
• DO NOT enter or allow entry into treated areas for a period of 12 hours after application.
• Oberon is toxic to aquatic organisms and beneficial insects such as pollinators. DO NOT apply this product directly to
freshwater habitats such as lakes, rivers, sloughs, ponds, creeks, marshes, streams, reservoirs, ditches and wetlands.
• Buffer Zones:
Application method Buffer Zones (metres † )
Required for the Protection of:
Aquatic Habitats of Depths Terrestrial
Less than 1 m Greater than 1 m habitat
Ground 10 3 2
Fixed wing airplane 800 100 85
See page 35 for an explanation of the different habitats.
• Buffer zones can be reduced by 70% when using shrouds and by 30% when using cones mounted less than
12 inches from the crop canopy.
†
Distance measured as metres from the downwind edge of the spray boom to sensitive habitat.
• DO NOT mix, load or clean equipment within 30 metres of wellheads or aquatic systems.
• Rotational plant-back intervals for:
º Field corn – immediate plant back
º Wheat, barley and alfalfa – 30 days
º All other crops – 12 months
Precautions:
Apply Oberon insecticide during pre-bloom, early bloom or late bloom when pollinators are not present in the field. DO
NOT apply Oberon when pollinators are actively foraging in the treatment area.
Storage: Store in a cool, dry place in such a manner to prevent cross contamination with other pesticides, fertilizers, food
and feed.
DO NOT store below freezing.
