  • Publication number: 20210315143
    Abstract: ‘FAES1307’ is a new and distinct zoysiagrass (Zoysia japonica Steud.) variety distinguished at least by its medium leaf texture, high turfgrass quality, good drought tolerance, improved winter turfgrass color retention, and low incidence of large patch disease caused by Rhizoctonia solani anastomosis group 2-2 LP. Compared to its parents and commercial checks, ‘FAES1307’ has a shorter canopy height and is a more prolific producer of stolons. It tends to have shorter leave lengths and moderate leaf widths. Its flag leaf height is similar to its female parent, ‘FAES 5309-12’ while its flag leaf width is similar to its male parent, ‘BA 123’. The seed head heights of ‘FAES 1307’ are shorter and consistent with the height of its female parent, ‘TAES 5309-12’. ‘FAES1307’ and its parents have narrower raceme widths; and shorter raceme lengths compared to to ‘Meyer’ and ‘SS-500’.

  • Patent number: 6892657
    Abstract: A turf care system and method uses simultaneously fired pulses of high-pressure liquid jets of the mixture shot toward the ground. The liquid is mixed with dry grass seed shortly before being delivered to a high-pressure liquid/seed pumping system, which uses an accumulator and sequencing valve to produce at regular repetitive intervals pulses of the liquid/seed mixture under high pressure. The pulses are delivered to an elongated hydraulic manifold having multiple nozzles pointed downwardly, which are spaced from one another and the ground by predetermined distances. The momentum of the high-pressure jet of liquid/seed mixture issuing from each nozzle cuts through overlying vegetation to deposit the seeds into the crown of the soil at predetermined desired depth. Spray patterns are determined by nozzle orifice shape, and are preferably selected to provide a shallow knife slit-like opening or trench in the crown of the turf.

  • Patent number: 6431096
    Abstract: A turf care system and method for injecting a liquid/seed mixture into soil, such as the crown of an established turf stand, using simultaneously fired pulses of high-pressure liquid jets of the mixture shot toward the ground. The liquid, typically water, is mixed with dry grass seed shortly before being delivered to a high-pressure liquid/seed pumping system, which uses an accumulator and sequencing valve to produce at regular repetitive intervals pulses of the liquid/seed mixture under high pressure. These pulses are delivered to an elongated hydraulic manifold having multiple nozzles pointed downwardly, which are spaced from one another and the ground by predetermined distances. The momentum of the high-pressure jet of liquid/seed mixture issuing from each nozzle cuts through overlying vegetation to deposit the seeds into the crown of the soil at predetermined desired depth.

  • Patent number: PP34352
    Abstract: ‘FAES1307’ is a new and distinct zoysiagrass (Zoysia japonica Steud.) variety distinguished at least by its smooth leaf texture with occasional fine hairs on the upper surface, high turfgrass quality, good drought tolerance, improved winter turfgrass color retention, and low incidence of large patch disease caused by Rhizoctonia solani anastomosis group 2-2 LP. Compared to its parents and commercial checks, ‘FAES1307’ has a shorter canopy height and is a more prolific producer of stolons. It tends to have shorter leave lengths and moderate leaf widths. Its flag leaf height is similar to its female parent, ‘FAES 5309-12’ while its flag leaf width is similar to its male parent, ‘BA 123’.
