Abstract
An improved termiticidal combination is formed by adding a liquid cellulose source to a standard liquid termiticide. The cellulose source may be a water soluble polyester such as a cellulose ether like methyl cellulose. The cellulose in the combination functions as termite bait, thereby enhancing the effectiveness of the poison, even at lower concentrations, by inducing termites to ingest poisoned cellulose and return with it to share it with the colony. The liquid form allows the combination to be applied with a standard power sprayer, and permits laying of a continuous barrier or curtain as well as injection spraying into walls of structures.
Claims6
An enhanced termiticide mixture comprising about 42% to 43% chlorpyrifos technical and 57% to 58% inert ingredients by weight, said inert ingredients including a solvent, an emulsifier, and an enhancing mixture of powdered cellulose and an anticaking agent, said enhancing mixture comprising from about 0.5% to about 10% by weight, said anticaking agent comprising about 10% to about 20% of said enhancing mixture, and said solvent and said emulsifier, in a proportion of about 5 to 1 by weight, comprising the balance.
A method of preparing an enhanced chlorpyrifos based termiticide, comprising the steps of preparing a standard chlorpyrifos concentrate comprising chlorpyrifos technical, solvent and emulsifiers, preparing an enhancing mixture of powdered hydroxyethylcellulose and anticaking agent in a ratio of about 5:1 to about 10:1 by weight and adding the enhancing mixture to the chlorpyrifos concentrate in a proportion of about 0.5% to about 10% by weight.
