What are they and how do they help plants and you? PGR’s are organic compounds
Cambistat improves tree health by reducing the amount of energy allocated to canopy growth. This energy can then be used for other processes such as fibrous root development and defense chemicals. This makes Cambistat an ideal tool for complementing other tree healthcare practices and treatments. Cambistat has been shown to reduce growth, and its active ingredient has been shown to increase a tree’s ability to withstand drought conditions and the effects of urban tree stress.
Trimtect is an innovative formulation of Cambistat for use on shrubs, small trees, and bedding plants. Trimtect consistently reduces the shoot growth of plants by 30-70% during the growing season. Sprayed on the foliage, Trimtect is formulated specifically for shrubs, flowers, and other landscape plants to maintain a manicured appearance with less maintenance.
The active ingredient in Cambistat and Trimtect is a molecule called paclobutrazol. The molecule is part of a highly active group of plant growth regulators and fungicides known as triazoles. Widely used for decades for tree care and in vegetation management, paclobutrazol consistently reduces the shoot growth of plants by 30-70% during the growing season.
How It Works
When applied, a lone electron on a nitrogen atom reacts with the enzyme kaurene oxidase. This interaction blocks a key step in the formation of gibberellins, resulting in a reduction of vegetative growth.
