2004 Cortez Burgundy

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.

Cortez Burgundy November 30th11/30

These Cortez Burgundy are salable at this stage, but 3-4 more days of development will make them look even better. The plants are strong, so the little extra height is not a problem. The amount of elongation we got in late Oct. and early Nov. was a surprise. Looking back, we should have made a stronger spray on Oct. 12 or 19. We could have applied the drench on Nov. 2, but there would have been a strong chance of affecting bract development. Compare how we handled this crop to the way we did Prestige to see a better height control plan.

Cortez Burgundy November 23rd11/23

This crop is about a week from finish. It will be a little tall, but should look good.

Cortez Burgundy November 16th11/16

We did not expect this much late growth on Cortez Burgundy. The effect of last week's drench is just starting to show and we anticipate only 1/2 to 1 inch of additional growth as it finishes.

Cortez Burgundy  November 9th11/09

With the continued warmer conditions, these plants grew another 1.75 inches this past week. Today, we drenched with Bonzi at 1 ppm and the crop will probably finish around 16 inches.

Cortez Burgundy  November 2nd11/02

In the warmer temperatures the past week, the Cortez Burgundy grew about 1.75 inches and should continue at this pace. We will likely apply a drench next week.

Cortez Burgundy  October 26th10/26

There was an error in the previous Cortez Burgundy graph and it was changed this week. The former finish date was Nov.23rd, but should have been Nov 30th. Very early color is starting on a few plants and the crop should be showing color next week. This puts it on schedule to finish about Nov. 30. The plants look like they will continue growing at a good rate for a couple more weeks. So, we anticipate applying a drench about Nov. 9th.

Cortez Burgundy  October 19th10/19

We are not seeing color on this crop. The plants are actively growing and look like they will grow more this coming week than the past week. So we sprayed with Cycocel at 1,250 ppm to slow them just a little. Without this spray, we would probably need to drench on Nov 2 or 9. Hopefully the spray will move that a week later or even eliminate the need to drench.

Cortez Burgundy  October 12th10/12

Like most of the other crops elongation increased this past week. We are not spraying this crop this week and will see what it does the next couple of weeks.

Cortez Burgundy  October 5th10/05

This crop slowed down more than expected this week, which was probably due to the much better weather we had.

Cortez Burgundy  September 28th9/28

This crop looks good now and we will see what it does this next week.

Cortez Burgundy  September 21st9/21

This crop is starting to grow now. We applied the low rate spray (B-Nine/Cycocel at 1,000 ppm each) this week just to hold elongation back a little.

Cortez Burgundy  September 14th9/14

We will wait to see how this variety grows before starting PGRs.

Cortez Burgundy September 7th9/07

Cortez Burgundy is a popular novelty that should not be difficult to control. It should exhibit strong even growth and not stretch at the end.
