  • Planting apparatus with improved liquid pesticide delivery device and related method for delivering liquid pesticide
    Patent number: 6289829
    Abstract: A planting machine for delivering liquid pesticides to the soil mixing zone preceding the furrow closing mechanism to effectively distribute liquid pesticide throughout soil covering seed in a furrow. The planting machine has a furrow opening mechanism, seed dispensing means, and furrow closing mechanism and includes a seed positioning means mounted on the seed dispensing means for effectively locating seeds in the furrow. Also, the planting machine includes means for liquid pesticide spray delivery mounted thereon so as to direct a spray towards the furrow closing mechanism and into the soil mixing zone being created by the furrow closing mechanism. The means for spray delivery can be mounted on the conventional seed positioning means as well as independently mounted on the planting machine.

  • Chimeric gene for the transformation of plants
    Patent number: RE37287
    Abstract: Chimeric gene for conferring to plants an increased tolerance to a herbicide having as its target EPSPS comprises, in the direction of transcription, a promoter region, a transit peptide region, a coding sequence for glyphosate tolerance and a polyandenylation signal region, wherein the transit peptide region comprises, in the direction of translation, at least one transit peptide of a plant gene encoding a plastid-localized enzyme and then a second transit peptide of a plant gene encoding, a plastid-localized enzyme. Production of glyphosate-tolerant plants is disclosed.
