Specialty Potato Variety Evaluation, 2002 

General Comments

A goal of the specialty potato variety trial is to identify potato selections that expand the selection of commercial varieties for Florida.  In 2002, the trial was conducted at the UF Farm and two grower farms in the Hastings area.  Established varieties were included for comparison of production and quality values.  The clone main effect data, an average over all test sites, is presented.

Potential Herbicides for Vegetables

There are several herbicides that have a potential for labeling in Florida in the near future. The labeling is contingent upon the company and because it is mentioned here, does not guarantee that the label will be issued. But, if a label is issued with this update, hopefully you won’t be caught off guard.

As you know, Matrix (rimsulfuron) was labeled in tomatoes and Aim (carfentrazone) and Sandea (halosulfuron) were granted section 18 labeling this year. Full labels for Aim in tomato, pepper and eggplant row middles are expected shortly as well as a full label for Sandea on tomatoes and for pepper and eggplant row middles. Labels or Sandea are also expected in snap beans, muskmelon and watermelon. The cucurbit labels will all be different since cucumber (already labeled) and muskmelons are fairly tolerant to Sandea over-the-top while watermelon is sensitive at different timings.

Labels for Sinbar (terbacil) are expected in strawberries and under mulch in watermelons. Watermelons are very tolerant of Sinbar, but the other cucurbits are not.

At this writing, Dow is meeting to discuss the labels for Stinger (clopyralid) on the cole (cruciferous) crops and over-the-top of strawberries. The strawberry label may have to be a third-party label. Stinger applied over cabbage, collards, mustard, etc. have been shown to be safe and will control a number of winter annual weeds.

Dual Magnum (S-metolachlor) is now labeled under a third-party agreement for use pretransplant in pepper. A label for pretransplant use under mulch is also expected in tomato.

A full label for the use of glyphosate in row middles has been issued for Roundup Weathermax. The weathermax formulation is not sold in Florida presently, but a supplemental label has been issued for the use of Roundup Ultramax in row middles.

Hopefully, we will be seeing the above labels shortly. For your information, there are a number of trials in progress to establish tolerances of several herbicides in vegetables. Some of the ones that are of interest include: Goal (oxyfluorfen) under mulch in pepper and cucumber; Goal row middle in strawberry; Valor (flumioxazin) row middle application in tomato, pepper and strawberry; Authority/Spartan (sulfentrazone) in potato and strawberry; Prowl (pendimethalin) in strawberry; and Cobra (lactofen) in tomato and pepper row middles.

If there are herbicide uses or needs in vegetables that you know of, please contact me so these can be included in the next priority meetings of IR-4.

Plastic Mulch Color and Soil Temperatures

Plastic mulch surface color has been reported to affect growth, yield, quality of upwardly reflected light, and soil temperatures under the mulch. Much of the temperature work has been done to either increase early season soil temperatures or to reduce summer soil temperatures. The data presented here are a part of a larger study using various colors of plastic mulch in a double cropping system. The time period for the second crop was from Aug. to Oct. 2002. With the six colors used (blue, red, silver-gray, black, white, and white-on-black ), there was little measurable temperature differences under the plastic mulch at a soil depth of 5 cm. The morning temperatures taken at 8:30 am (Fig. 1) indicates a slightly higher soil temperature than the air or bare ground for the silver (gray ) and white mulches. The differences from the highest morning soil temperature (24.5 c ) to the lowest (23.3 c ) is only 1.2 c. In the afternoon taken at 3:30 pm (Fig. 2) all mulch colors resulted in higher soil temperatures than the air or bare ground. Again, the difference between the bare ground which had the lowest soil temperature (28.0 c ) and the blue mulch which had the highest (30.4 c ) was only 2.3 c. The soil temperatures for all plastic mulches tested only differed by 0.9 c in the afternoon measurement. Table 1 and Table 2 have the data for each measurement for temperatures of each treatment over the Aug. to Oct. time period. In this study, mulch color had some influence on soil temperatures at 5 cm, but not as much as expected. The temperatures were taken in moist soil due to the drip irrigation system.
