Atrimmec Plant Growth Regulator, PGR, PBI Gordon

Atrimmec Plant Growth Regulator is a systemic plant growth regulator which works by blocking the plant hormones that stimulate growth. Applied as a foliar spray, it is absorbed by the leaves and translocated to the shoot tips where it interrupts apical dominance and temporarily stops shoot elongation. One trimming and one Atrimmec application can last the entire season on many plants.

Spraying shrubs, hedges, trees and groundcovers not only reduces trimming and pruning labor by 50% or more, but Atrimmec also improves the appearance of landscape ornamentals. It promotes lateral branching giving plants a more dense, fuller look. Hedges and shrubs that show irregular shapes including damage from pests and weather, can fill in lushly, even on the old wood, particularly if treated under optimum growing conditions.

Atrimmec is now labeled for reduction/elimination of nuisance fruit on landscape plants and trees including olives.
