Decision 1L — Pure Deltamethrin Insecticide (25g/L Emulsifiable Concentrate)

A professional-grade deltamethrin insecticide — pure deltamethrin 2.81% (25g/L) in emulsifiable concentrate (EC) form, IRAC Group 3A pyrethroid mechanism of action. For serious pest pressure where lower-strength products have failed. Light aromatic solvent naphtha as the coformulant base. A proper agricultural-grade product, not a domestic pesticide.

Why growers might choose Decision:

• Pure deltamethrin formulation (25g/L) — strong active, effective against a wide pest range
• Emulsifiable concentrate — mixes with water for spraying via pump sprayer
• IRAC Group 3A pyrethroid — well-established mechanism, fast-acting contact kill
• Effective against persistent pest problems — handles infestations weaker products can't
• 1L concentrate — small volume goes a long way at low dilution rates

Who it's not for:

Critical safety warnings: This is a serious agricultural pesticide — wear full PPE (gloves, respirator, eye protection, full cover clothing) during handling and application. Never apply in confined spaces with people or pets present. Ventilate thoroughly before re-entry. Do not use during flowering — residue on flowers is unacceptable. Use only in veg stage and stop well before flower transition. Highly toxic to fish and aquatic life — do not release into drains or waterways. Deltamethrin is classified for use by trained applicators; only use if you are competent with agricultural chemical handling. Always read and follow the product label precisely. Keep out of reach of children and pets. For most home growers, CannaCure, Pyrethrum 5EC, or Vertimec are more appropriate first-line pest controls.
