Pinching and Growth Regulators
Foliar sprays of B-Nine at 3,500 ppm applied 2 to 3 times are beneficial. First application can be done 1 week after transplant, followed by a second application 1 week later. If necessary, a third application can be done 10 to 14 days later to hold the crop. If the crop is targeted to finish in late Spring or early Summer during
warmer growing temperatures, try using a foliar spray of B-Nine at 5,000 ppm instead of 3,500 ppm.
Pest and Disease Management
Avoid moisture/humidity condensation in the greenhouse, as this can cause Botrytis. Also incorporate a preventative fungicide program for Powdery Mildew.
