Osaria Ultra 70 WDG Insecticide - 18 Ounces (compare to Altacor eVo)

Osaria Ultra 70 WDG Insecticide - High-Load Chlorantraniliprole for Lepidopterous Pest Control in Tree Nuts & Fruit Crops

Osaria Ultra 70 WDG from Atticus is a professional-grade, water-dispersible granule insecticide formulated with chlorantraniliprole at 70% active ingredient, the same active ingredient used in Altacor eVo. It delivers systemic, residual control of key lepidopterous larvae and Japanese beetles across almonds, apples, grapes, pistachios, walnuts, and many other tree nut and fruit crops. Its high-load WDG formulation means lower use rates per acre with excellent rainfastness, making it a cost-effective fit for IPM programs.

Key Benefits

• High-concentration formulation - 70% chlorantraniliprole WDG delivers more active ingredient per ounce, requiring only 1.1-2.2 oz/acre for effective control.
• Systemic activity - absorbed by the plant to control pests that move onto foliage after application, providing residual protection beyond the initial spray.
• Rapid pest cessation - affected insects stop feeding quickly, become paralyzed, and typically die within 1-3 days of exposure.
• Broad pest spectrum - effective against codling moth, navel orangeworm, peach twig borer, light brown apple moth, Japanese beetles, and a wide range of other lepidopterous larvae.
• Lower risk to beneficials - selective mode of action poses reduced risk to beneficial insects, supporting IPM strategies.
• Flexible application - labeled for ground (foliar), aerial, and overhead sprinkler chemigation on specified crops.

Key Crops & Target Pests

For use on: Almonds, apples, grapes, pistachios, walnuts, and a wide range of additional tree nut and fruit crops as listed on the label. For agricultural use only, not for residential, ornamental, nursery transplant, or greenhouse use.

Key pests controlled include: Codling moth, navel orangeworm, peach twig borer, light brown apple moth, Japanese beetles, and other lepidopterous larvae as listed on the label.

Application Rates & Timing

Apply when insect populations reach locally determined economic action thresholds. Time applications to the most susceptible pest stage, typically at egg lay, egg hatch, or newly hatched larvae, before populations reach damaging levels:

• General use rate: 1.1-2.2 oz/acre (0.047-0.098 lb AI/acre); use the higher rate when pest pressure is high.
• Ground (foliar): Use a minimum of 30 gallons per acre of water; ensure thorough, uniform coverage for best results.
• Aerial: Use a minimum of 10 gallons per acre of water (5 gpa minimum for cranberry); refer to label for crop-specific guidance.
• Chemigation: Labeled for overhead sprinkler chemigation on specified crops; see label for eligible crops and system requirements.
• Tank mixing: Compatible with other labeled pesticides for the same crops; conduct a jar test before first use, and do not mix directly with pure liquid fertilizers.

For resistance management, rotate away from Group 28 insecticides after each treatment window (approximately 30 days or one pest generation). Do not exceed 2 successive Group 28 applications within a single treatment window. Observe all REIs, worker protection requirements, and site-specific use limitations on the label.

ALWAYS READ AND FOLLOW LABEL DIRECTIONS BEFORE USE.
