The present invention relates to the field of soil fumigation, and more particularly to a fumigant formulation comprising from 0.10% to 0.4% by weight of fumigant, said formulation being particularly suitable for dropwise administration, and also to the use thereof. The present invention also relates to a method of pesticide treatment by fumigation of soils and/or substrates that employs such a formulation, administered dropwise.

A composition includes a gel carrier having a gel phase at a first, ambient temperature and a liquid phase at a second, higher temperature, and an insect repellent chemical in the carrier. The repellent chemical has substantially no volatilization from the gel carrier when the gel carrier is in the gel phase, but volatilizes from the gel carrier when the gel carrier is in the liquid phase.
