Plant Growth Regulator Guidelines
“You can completely stunt the crop to the point where it will not grow again,” says Chris Fifo, technical services advisor at Swift Greenhouses in Gilman, Iowa. “With some crops, you can excessively delay flowering if you apply too much, too earlyâ€“and you’ll miss the target window for sales.

It can be very costly.” It’s all too easy to slip up when applying PGRs, and the price for doing so increases exponentially in a tough economic environment like the one facing growers today.
