Plant growth regulators paclobutrazol

Paclobutrazol was the first 1,2,4-triazole containing compound to be introduced in agriculture as a broad-spectrum plant growth regulator (4). In addition it possesses good fungicidal activity. 

Heterocycles are contained in a large number of agrochemicals . Triazoles, such as cyproconazole, are effective plant fnngicides and have mechanisms of action - inhibition of steroid synthesis - similar to those used medicinally. Other triazoles have limited antifungal activity, bnt are nseful plant-growth regulators, for example paclobutrazol. Another widely used fungicide is davicil.
