New! Rootstock with stronger germination and bacterial wilt resistance.
In our trials, Shin Cheong Gang performs similarly to Maxifort but with dramatically improved germination uniformity and seedling vigor: both important criteria for successful grafting. High vigor makes Shin Cheong Gang suitable for long crop cycles. Offers an excellent, broad disease package including resistance to Rhizoctonia and bacterial wilt. High resistance to Fusarium wilt (races 1, 2, and 3), Fusarium crown and root rot, Rhizoctonia, tomato mosaic virus, and Verticillium wilt; and intermediate resistance to bacterial wilt and nematodes. For use as rootstock only. Item Form:(P) Pkt of 100 seeds
SCIENTIFIC NAME: Solanum lycopersicum
CULTURE: For more information on grafting with rootstock tomatoes, please refer to one of our production guides: Top Grafting Tomatoes or Side Grafting Tomatoes. Maxifort rootstock can lead to uneven germination in some conditions; if grafting to Maxifort, see our Maxifort production guide for tips on mitigating this issue. After cotyledons (first leaves) have expanded, fertilize with a complete nutrient solution (EC 1.0, pH 5.8) or equivalent as needed to keep plants dark green and healthy; increase EC as plants grow. Once the grafted plants have healed, continue by growing and managing the plants as you would normally. Grow plants at 66-68°F (19-20°C) day and night temperature. When transplanting into the greenhouse, maintain 73-77°F (23-25°C) day and night temperature for a few days after transplanting to promote rapid vegetative growth and root establishment. Once fruit begins to set, lower night temperature to 62-66°F (17-19°C) and keep a daytime temperature of 68-72°F (20-22°C).
DISEASES AND PESTS: Regularly schedule releases of beneficial insects to control pests.
