Abstract: The present invention relates to norbormide analogs having rodenticidal activity; rodenticidal compositions comprising the analogs; uses of the analogs as rodenticides; uses of the analogs in the manufacture of rodenticidal compositions; and methods for controlling rodents using the compositions.

Abstract: The present invention discloses an automated method for optimizing irrigation, whereby different parts of a field are irrigated different amounts, based at least in part on an analysis of spatial soil properties of the field, and extrapolation of data from soil sensors placed in the different parts of a field.

Abstract: The invention provides a soil moisture content measurement system comprising a porous plate arranged to support a soil sample; a hanging water tube extending downwardly from the porous plate, the tube arranged to convey liquid toward and away from the porous plate; a measuring capillary tube in connection with the hanging water tube, the measuring capillary tube arranged to convey liquid toward and away from the hanging water tube; measurement apparatus configured to measure the movement of liquid within the measuring capillary tube; and a data memory configured to receive and store data from the measurement apparatus representing liquid movement measurements within the measuring capillary tube. The invention also provides a related method of measuring soil moisture content.

Abstract: The trap (42, 82) is based around a spring mechanism (24, 60) comprising a substantially rectangular sheet of spring material folded to be substantially C-shaped in cross-section. In one embodiment (FIG. 6), portions (64, 65) of the spring mechanism (60) are adapted to be killing surfaces. In another embodiment (FIG. 2), the spring mechanism (24) is provided with arms (28, 29) that support jaws (36, 37). A setting mechanism (53/54, 77) holds the spring mechanism (24, 60) in an armed position and the trap (42, 82) is triggered when a trigger mechanism (49, 75) is moved by an animal which in turn disengages the setting mechanism (53/54, 77) and allows the killing surfaces (portions 64, 65) or jaws (36, 37) to come together on the animal therebetween.
