2011 Prestige Red
Growth Regulators Applied / Height graph
Graph shows projected plant heights during production of the crop. Dots are plotted actual height each week. Arrows indicate when PGRs are applied with details in the weekly notes. We use the “late” graphical tracking curve and heights are from bench to height of growing tip. Heights are plotted from date of pinching to projected date of finish.
Notes
11/29
This crop of Prestige Red looks good and has finished on schedule. 2010 was also an early year for Prestige, and 2009 is an example of a heat delay year. The mild days of late Oct. resulted in greater response to the PGR drench than expected. The Fascination worked well to give 1.5 to 2 inches more growth. This is a good example of using Fascination to rescue a crop that is about to finish a little short.
11/22
This crop of Prestige will finish next week on schedule and we are seeing good bract expansion.
11/15
This past week we had a few warmer days, which along with the Fascination gave use more elongation than expected. Now the new growth looks a little stretched and the bracts are sticking up (which is a common effect from Fascination). The bracts will lie down over the next couple of weeks and this crop should finish fine.
11/8
This crop of Prestige is headed to finishing shorter than desired. Part of this is due to the relatively mild days we have had and the fact we are targeting a slightly larger 15-17" plant this year. Also, the early initiation due to little heat delay gives less vegetative time. The plants look good and leaf size is good. The plants just are not elongating. We are spraying with Fascination this week at 3 ppm. Hopefully, this will give an inch of elongation and get the developing bracts up above the leaves.
11/1
Elongation in these Prestige has slowed a little more than desired. The shoot tips look like the plants will continue growing. We will see where they are next week.
10/25
About a third of this Prestige crop is showing color now and the crop could finish a little ahead of schedule. High temperatures were more moderate this past week and we got more response from the drench than we expected. The plants look good and should continue to grow.
10/18
This crop continues to look good. We are applying a Bonzi drench at 0.1 ppm with the objective of slowing growth just a little.
10/11
This crop looks good and the plants look like they will continue growing at a good pace. We will see where the crop is next week, but do expect to do another drench next week.
10/4
Our cool to normal weather means that this crop of Prestige should be initiating now, and it should finish on schedule. The centers of the shoots are fairly tight and plants are being slowed by last week's PGR. With our cool temperatures this effect will likely last another week.
9/27
The Prestige crop is growing faster now. Looking at the shoot tips, they are starting to elongate more and are sticking up above the leaf canopy. We are applying an early Bonzi drench at 0.1 ppm this week. If the forecast for cooler weather the next couple of weeks happens, then there should be only minimal heat delay. This would mean that height control on this crop will not require too much PGR.
9/20
The Prestige crop is growing better now. We are not making a PGR application this week and will see where the crop is next week.
9/13
Our greenhouse temperatures have been very hot and these Prestige are starting off a little slower than normal. But with more seasonable temperatures now we expect they will start growing faster.
9/6
We will see how these plants do over the next week.
8/30
We include Prestige Red each year which provides a standard to use in comparing years and new varieties. PGR requirements for Prestige largely depend on the weather with more height control a little more difficult in warmer years.
