1958 Gleckers Seed Catalog says about Peron Sprayless….
” A miraculous variety developed by Prof. Abelardo Piovano at the National University of Argentina. Medium size semi-determinate bushy vines are very resistant to fungus diseases common to tomatoes. Foliage is semi-dense. A very heavy yielder of large size, slightly flattened globular fruits of the most extraordinary quality. Interior of fruits very solid and meaty, without any core. Very small and numerous seed cells, form a perfect fruit structure. Ripens to a beautiful deep red color over the entire fruit without green or yellow shoulders. Its tough, velvety-smooth skin is very crack resistant and easily peeled without immersing in hot water, a rarity not found in other varieties. Flavour is mildly acid and of a most delicious taste. Fruits keep exceptionally long after ripening. The Peron tomato is called sprayless because it will produce a normal crop of quality fruit in most areas without any disease control. No other tomato was ever introduced that received so many voluntary complimentary reports and we have them by the hundreds. No other tomato ever introduced has shown such wide adaptability. These reports have come from practically every state, in areas where they were unable to grow any other strains. It performs wonderfully in the tropics where the fungus diseases get out of hand. From Alaska we have a report it is wonderful in the greenhouse. Its drought resistance is terrific.”
