How to Use Orthene WSP Turf, Tree, and Ornamental Insecticide (0.773 lb Can by AMVAC)

Important Safety Note: Orthene WSP is a restricted-use pesticide in many contexts and is intended primarily for professional use (e.g., commercial growers, landscapers, golf courses, and nursery operators). Always read and strictly follow the full product label for your specific region, as registrations and restrictions vary by state. Wear appropriate personal protective equipment (PPE) including gloves, long sleeves, pants, and eye protection during mixing and application. Do not apply near water bodies, and observe re-entry intervals (typically 24 hours).

Product Overview

The 0.773 lb can contains pre-measured water-soluble packets (WSP) of acephate 97.4%. These packets dissolve easily in water, reducing handling exposure and ensuring accurate dosing.

General Mixing Instructions

1. Fill your spray tank halfway with clean water and begin agitation.
2. Add the required number of intact water-soluble packets directly to the tank (do not open or cut packets).
3. Allow packets to fully dissolve (about 5 minutes; agitation helps, especially in cold water).
4. Add remaining water and any compatible tank-mix partners.
5. Maintain continuous agitation during application for uniform distribution.

Application Methods

• Foliar Spray: Most common method for trees, shrubs, ornamentals, and turf. Use ground equipment for thorough coverage of foliage.
• Soil Drench: For systemic uptake via roots, especially on container-grown plants or around tree bases.
• Tree Injection: Professional method for certain tree pests (follow label rates for soil injection on ornamentals).
• Broadcast or Mound Treatment: Limited for turf or specific pests like ants.

Typical Application Rates (Examples from Label Guidelines)

Rates vary by pest, site, and plant type—consult the exact label for your target pest. Common rates per 100 gallons of water:

• Most insects (aphids, thrips, whiteflies, mealybugs, scales, lace bugs, leafrollers): 4–8 oz (1/4–1/2 lb) product.
• Tougher pests (caterpillars, gypsy moth larvae, grasshoppers, weevils): Up to 16 oz (1 lb) product.
• Turfgrass (e.g., sod farms, golf courses): Up to 16 oz per acre.
• Do not exceed maximum annual or per-application limits (e.g., often 1–4 lbs active ingredient per acre per year depending on site).

Apply when pests are active, preferably early morning or evening for better coverage and reduced drift. The product becomes rainfast quickly after absorption (within hours) and provides residual control up to 3 weeks.
