  • Publication number: 20140378304
    Abstract: The present invention relates to an aqueous agrochemical spray solution containing an agrochemical active and a surfactant. The spray solution comprises a dispersed phase comprising dispersed particles which have an average particle size between 1 to 100 microns and the concentration of said dispersed particles is from about 0.001 to 5 wt %. The aqueous agrochemical spray solution is capable of reducing the volume of the fine droplets in mist whose size is less than 150 microns during spraying by at least 20% compared to the same aqueous spray solution without the presence of the surfactant. The present invention also relates to a method of reducing the spray drift of an aqueous agrochemical spray solution upon spraying with a spraying apparatus. The method includes adding the surfactant to the aqueous agrochemical spray solution in an amount effective to form the dispersed phase.

  • Publication number: 20140259873
    Abstract: A two-piece, sanitary, safe and humane mousetrap comprising an entrance device and a container, wherein the entrance device comprises a tunnel, a one-way door, a mousetrap support piece, a fastening mechanism, and a door locking mechanism, is disclosed. Specifically, the mousetrap is formed by inserting the container to the entrance device from the back of the tunnel all the way to the one-way door. Preferably the one-way door comprises a pivotal wire door with a push-and-lock mechanism or comprises a gate with a touch-and-drop mechanism. The preferred entrance device is able to fit a common bottle. When the entrance device contains a flat rim fitted around the tunnel, the entrance device is capable of fitting containers of various sizes and shapes during repeated uses.
