Problems solved by technology

[0011] It will be noted that none of the 'traditional' fumigants have the desired fumigant properties and that in Australia phosphine will be the only registered fumigant available for agricultural use

Embodiment

[0066] 1. Stability study

[0067] The stability of ethyl formate (EtF) and methyl isothiocyanate (MITC) as fumigant formulations stored at 25°C was evaluated over a period of 1 day, 1 month and 2 months. Table 1 below shows the percentage of original fumigant present after different storage times (M / Mo). This is also represented graphically in Figure 1. The results indicated that ethyl formate and methyl isothiocyanate were stable when stored for two months after formulation.

Abstract

New pesticide compositions comprising an alkyl formate and an isothiocyanic ester are described, as are methods of delivering fumigants and methods of pest control using a combination of fumigants.

Description

[0001] The present invention relates to novel insecticide compositions comprising alkyl formates and isothiocyanates, methods of delivering fumigants and methods of controlling pests using fumigant combinations. Background technique [0002] Fumigants are widely used for extermination and protection from infestation by pests, usually for the protection of granular products (commodity) (such as grain) and other stored products (including durable and perishable food or cut flowers), porous loose materials (for example, soil or wood) and space (empty buildings or empty buildings with products). Ideally the fumigant should be toxic to insects, rodents, mites, nematodes, bacteria, fungi and their spores, viruses and molds, and other pest biota. It should be effective at low concentrations. Ideally, it should be low absorbed by the materials in the fumigated area. It should have low phytotoxicity to the product. It should have low mammalian chronic toxicity and no or inert residu...
