Air volume should match canopy volume

  • March 1st, 2013

As growers move to modern, high-density planting systems to improve yield and orchard management, they need to match the sprayer output to the modern canopy. The closely planted trees and narrow rows require totally different operating parameters than the large, traditional tree canopies of older orchards.

Since coming to Cornell [...]

Nurseries working to provide apple growers with the well-branched, “feathered” trees they want to plant can use the chemical MaxCel and will find it as effective and safer than Tiberon in inducing branching.

That’s the good news coming from Cornell University researchers and nurseries that have worked with them. They [...]
