Problem

Some nitenpyram formulations degrade through sunlight exposure or hydrolysis, while solvent-based approaches intended to improve stability may be too expensive.

Why it matters

A stable concentrate could improve storage and formulation consistency for crop-protection products, but pesticide efficacy, safety, environmental impact, and approval remain essential.

Approach

The formulation combines a neonicotinoid pesticide with dimethylformamide, methanol, and xylene in a stated solvent ratio plus anionic and non-ionic surfactants. The concentrate is diluted with water to form an emulsion for application to plants, seeds, soil, or plant habitat.

Who may benefit

Potential beneficiaries include agrochemical formulators, crop-protection researchers, pesticide manufacturers, agricultural distributors, and growers after product-specific regulatory authorization.

Potential value

The disclosure pairs a defined three-solvent ratio with mixed surfactants and elevated neonicotinoid loading, while claiming at least two years of room-temperature shelf life under CIPAC guidelines.

Background

Background

Neonicotinoids are systemic insecticides used in agriculture and pest control. Nitenpyram acts on insect neural signaling and is sold in several formulation types, but the publication describes sunlight degradation in a water-dispersible granule and hydrolysis in a soluble-liquid product. Dimethylformamide can reduce hydrolysis, although solvent-heavy formulations may be expensive. The disclosed emulsifiable concentrate therefore combines nitenpyram or another listed neonicotinoid with a defined solvent blend and surfactant system intended to improve loading and storage stability.

Technology overview

Technology overview

The concentrate uses dimethylformamide, methanol, and xylene, including a 5:2:9 volume-ratio embodiment, together with anionic and non-ionic surfactants. A neonicotinoid such as nitenpyram is present at 15–40% weight per volume of the solvent mixture. Preparation dissolves pesticide particles in the mixed formulation until clear. For insect-control use, the concentrate is mixed with water to form oil droplets before application to a specified agricultural target.

Potential applications

Potential applications

  1. Candidate emulsifiable concentrate for approved agricultural insect-control products.
  2. Formulation platform for nitenpyram and other listed neonicotinoids.
  3. Crop, seed, soil, or plant-habitat treatment after product authorization.
  4. Pesticide storage-stability and emulsification research under defined guidelines.

Evidence-supported advantages

Evidence-supported advantages

  1. The solvent mixture has a defined DMF:methanol:xylene ratio embodiment.
  2. The claims cover 15–40% weight-per-volume neonicotinoid loading.
  3. Anionic and non-ionic surfactants are combined in specified concentration ranges.
  4. The patent claims at least two years of room-temperature shelf life under CIPAC guidelines.
  5. A specific nitenpyram formulation and broader neonicotinoid options are disclosed.

Development stage

Development stage

Formulation preparation, chromatograms, and a short-term sample are described; the claimed two-year shelf life, field performance, and regulatory status were not independently verified.

Commercial opportunity

Commercial opportunity

The formulation may interest licensed agrochemical and crop-protection partners. Commercialization requires independent long-term stability testing, field efficacy, crop-residue analysis, operator and bystander safety, solvent handling, pollinator and aquatic ecotoxicology, packaging compatibility, manufacturing economics, and jurisdiction-specific pesticide registration. Supply-chain controls would also be needed.
