Estamino is a strong, generative rootstock that puts a high proportion of energy into fruit. Easier to balance than Maxifort and Colossus. Especially useful for tomatoes in cultivation for six months or less, in unheated hoophouses, or with small-fruited (less than 100 gm) varieties. Good disease package for soil. High resistance to fusarium races 0-2, fusarium crown and root rot, leaf mold, nematodes, tomato mosaic virus, tomato spotted wilt virus, and verticillium wilt. For use as rootstock only. Seed has been organically primed to improve germination. Organically grown. Avg. 21,400 seeds/oz.
CULTURE: Sow seeds in desired medium 6-8 weeks prior to transplanting. Maintain 80-90°F (27-32°C) soil temperature. When first true leaves just show, transplant into cell-type containers or blocks. 2" or larger containers produce larger, stronger root systems; 4" blocks are the standard. Grow plants at 66-68°F (19-20°C) day and night temperature. After cotyledon 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. 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). TRELLISING: It is recommended to prune the plants to 1-2 stems and trellis up a string. HARVEST: Fully vine-ripen fruit only for local retailing or use. Pick fruit less ripe the further the distance and the longer the time between harvest and the customer. DISEASES AND PESTS: Use crop rotation or new media to reduce soil-borne disease problems. Regularly schedule releases of beneficial insects to control pests. DAYS TO MATURITY: From transplanting. Transplants: Avg. 950 plants/1,000 seeds. SEED SPECS: Seeds/oz.: (varies): Avg. 11,100. PACKET: 15 seeds.

Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits. Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
This symbol is assigned to only those varieties that we have found, based on our trials, to be the best performers in a climate-controlled greenhouse environment. These varieties have been selected based on proven vigor and disease resistance to sustain healthy growth through a longer season, high yields to justify the investment in the structure, and excellent flavor and appearance.
