The experiments were carried out to ascertain the influence of fruit yield and qualities of preharvest sprays of 100ppm, 200ppm and 400ppm 2-chloroethylphosphonic acid using the processing tomatoes cv. "Wasedaruma". 1. The term of ripeness was shorted by ethrel spray, especially, lot of 400ppm ethrel spray was shorted for 6 days. 2. Average fruit weight was not heavy in ethrel spray lots. The higher the ethrel concentration, the lighter the fruit weight. 3. On the handling harvest, number of fruits and fuits weight in early stages increased by ethrel spray. Especially, on lot of ethrel 400ppm spray was appeared severely, and climacteric peak of harvest were appeaed in about 10 days before than in other lots. 4. On the once over harvest, total harvest fruits weight were copious in control than in ethrel spray lots. 5. The hardiness, pH, sugar and inorganic matter contents of fruits did not differ between control and ethrel spray lot.
