Agrochemical Plannt Growth Regulator : 80% TC Ethephon
Product Description:
ethephon 80% TECH features: it is used in the following routins (1) The flower-stem and leaf length of eight daffodil and ten tulip cultivars were effectively reduced when ethephon (2-chloroethylphosponic acid) was applied to the soil. It controlled the growth of flower-stems better than leaves. The best time of application is when the shoots are about 810 cm in length. Too early application might cause blasting in sensetive cultivars of tulip. Spraying daffodils with ethephon reduced the plant height very little in 1978, but satisfactory in 1979. (2) The optimum concentration of ethephon is about 1000 ppm (100 mg a.i./pot) for most of the cultivars of daffodil tested and 250500 ppm (12.5 and 25 mg a.i./pot) for tulip. However, the amount of ethephon must be adjusted to the forcing temperature and the duration of cooling. The higher the forcing temperature, the stronger is the response to ethephon. Longer duration of cooling required higher concentrations. Too high ethephon concentration delayed days to flower with 13 days only when the bulbs were cooled for a short period of time. Ancymidol reduced flower stem length considerably more than leaf length. A concentration of 0.250.5 ppm (0.1250.25 mg a.i./pot) reduced the plant height satisfactory for all cultivars tested. (3) The McIntosh apple trees were sprayed with ethephon at 480 ppm + NAA at 40 ppm or with daminozide at 1000 ppm or ethephon + NAA + daminozide. These growth regulators were applied: ethephon for 1 or 2 weeks, NAA for 1 week and daminozide for 2 months before harvest. The experiment was designed with randomized blocks of 15 replicates /trees/per treatment and was carried out in 3 experiments stations in different parts of Poland.
