Prohexadione calcium inhibits synthesis of gibberellin, the plant hormone that regulates cell elongation, thereby inhibiting shoot growth.
It works by soaking seeds, watering, and foliar spray treatments. Compared with the currently widely used triazole retarders, prohexadione calcium has no residual toxicity to the rotation crops and no pollution to the environment, so it may replace triazoles.
--Control vegetative growth;
--Reduce the incidence and severity of fire blight;
--Keep a balance between canopy development and fruit production;
--Do not affect vegetative growth the year following application;
--No pollution to environment
