## Abstract

The pyrethrin-based nonphytotoxic arthropodicide is effective against a wide range of pests and is suitable for domestic and gardening uses. The composition comprises a trigliceride component derived from vegetable seed oils, a pyrethrum extract, and one or more surfactants. Optionally, antioxidants and emulsifiers may be added as well.

## Claims

### Claim 1

A ready-to-use insecticidal composition, comprising:
approximately 20 to 4000 ppm of active pyrethrin substances selected from the group consisting of pyrethrin I and II, cinerin I and II, jasmolin I and II, and mixtures thereof;
approximately 1 to 5% by weight of a triglyceride component derived from vegetable seed oils selected from the group consisting of canola oil, cottonseed oil, soybean oil, sunflower oil, safflower oil, rape seed oil, peanut oil, olive oil, and mixtures thereof;
approximately 0.05 to 1.0% by weight of a nonionic surfactant selected from the group consisting of ethoxylated sorbitan derivatives, ethoxylated fatty acids, and mixtures thereof;
a gum component present at about 50 ppm to 0.1% by weight; and
a balance of water,
the composition being environmentally compatible and having little or no phytotoxicity.

### Claim 2 (depends on 1)

The composition of claim 1 further comprising trace amounts of an antioxidant.
