Rigby Taylor Introduce first four cultivar, tetraploid perennial ryegrass blend

Changes in climatic conditions are proving increasingly challenging for turf maintenance. In recent times weather patterns have fluctuated from one extreme to the other.

Late frosts, snow or drought in spring, summer heatwaves accompanied by prolonged drought and periods of intense rainfall are all becoming commonplace.

Tetraploid perennial ryegrass has double the number of chromosomes (4n) compared with diploid perennial ryegrass, resulting in high vigour, extremely stress tolerant plants. One of the main benefits, increased cellular chloroplast, boosts chlorophyll production to aid energy absorption and processing.

The outcome is a robust, hardwearing, healthier plant that can better withstand climatic fluctuations and has a high level of Leaf Spot tolerance. Tetraploids also germinate and grow in colder temperatures down to 40°C and produce a stronger, deeper, dense root mass, increasing drought tolerance and tensile strength.

The ability to perform in colder temperatures and survive periods of heat and drought makes tetraploids indispensable. Four cultivars are now available in the 100% tetraploid ryegrass blend 4Tetra, the fundamental choice for turf performance and recovery throughout the seasons.

The blend:

  • 4Tetra Germin-8T treated
  • 25% Fabian tetraploid perennial ryegrass
  • 25% Tetrastar tetraploid perennial ryegrass
  • 25 % Tetragame tetraploid perennial ryegrass
  • 25% Tetragreen tetraploid perennial ryegrass

Germin-8T pre-treated seed is available on all the ‘R’ range of Rigby Taylor seeds. This unique liquid, potent seed coating maximises seedling development and establishments.

Containing a cocktail of specially penetrating surfactants, micronutrients and added mycorrhizae to supports plant health the addition of trichoderma viride provides a support package that protects against damaging turf diseases at their early stage of development.
