Benefits of Hot Pepper Wax as an Anti-transpirant:

An article in the January 2000 issue of The IPM Practitioner recognized that a group of polymer materials known to the green industry as Anti-transpirants might be used successfully as an alternative to chemical fungicides. For years, anti-transpirants have been used to improve transplanting results and to prevent moisture loss from plants exposed to environmental conditions that cause water stress.

As more of the chemical fungicides are removed from the market, interest has been renewed in the use of anti-transpirants for the reduction of fungal diseases.

Field-testing of Hot Pepper Wax Insect and Animal Repellent at Penn State University done in three consecutive years has consistently shown that in addition to its effect on targeted pests, HPW also acts as an anti-transpirant. Plants grew bigger, flowers and vegetable yields were improved at all rates and frequencies when treated plants were compared to the untreated control . During the 1999 growing season, PSU evaluated several experimental formulas on field tomatoes for their effect on Early Blight. Observations showed that even our current HPW formula delayed the occurrence of disease symptoms and resulted in increased crop yields, particularly on Heirloom tomato plants.


Reduced Application Rates

Field Equipment Application

Date: December 3, 1998
Crop: Romaine Lettuce
Insect: N/A

Location: San Ardo, California

Our original label indicated that Hot Pepper Wax (HPW) should be applied to a large acreage at a volume of 100 gallons per acre. While it is important to have thorough coverage of plant surfaces for good insect control, we thought that the labeled rate could be reduced. For this reason, PSU evaluated three reduced spray volumes.

Water sensitive spray cards were placed in a field of Romaine lettuce that was within five days of harvest. Three volumes of diluted spray were applied to 100 foot rows. Each test was replicated six times. 20, 40 and 60 GPA were applied using 8004 Flat Fan nozzles. Speed and pressure were adjusted to achieve the desired volume.

Application of Hot Pepper Wax insect repellent at 40 and 60 GPA were found to be as effective as 100 GPA on this crop. As a result, our labels now list the revised directions shown in quotes below.

"In general, 40 to 60 gallons per acre of the Hot Pepper Wax/water mixture is sufficient for row crops. Trees and ornamentals generally will require more per acre depending on size and spacing (possibly 100 to 200 gallons per acre)."


Whitefly Control

Hot Pepper Wax Insect Repellent

Date: Fall of 1998
Crop: Poinsettia
Insect: Whiteflies
By: Dr. E. Jay Holcomb, Penn State University

In an effort to find out more about how Hot Pepper Wax insect repellent works, PSU observed the appearance of whitefly eggs, larva & adults after applications of HPW Insect Repellent.

Ten poinsettias were treated with Hot Pepper Wax applied at a rate of 1:32 . Insect counts were taken at 4 days, one week and a week and a half after the spray application was made and compared to the counts of live whiteflies prior to spraying.

In addition to a reduction of live whitefly adults found on the leaves, the larva at most stages were killed. (This was determined by a change of color from brown to black as the larva died.) Eggs did not change color, so it was assumed they were not killed.

As a result of this test, we recommend growers focus their attention on breaking the whitefly cycle at the larval stage. Careful monitoring of this stage will determine frequency of application. Hot Pepper Wax Insect Repellent is labeled for applications as frequent as every 3 days for persistent infestations. Frequency should be reduced as soon as possible based on results obtained.

Testing shows that Hot Pepper Wax (HPW) Insect Repellent can be used in a low-volume applicator (Flora-Fume Electric Fogger) for greenhouse production, however dilution, frequency and insect monitoring are important factors for success.

HPW Insect Repellent should be mixed at the rate of 1:32 and applied at twice the volume recommended by the equipment manufacturer when using a low-volume applicator. Stronger dilutions may result in clogging of equipment. In this case, Flora-Fume recommended 1 ounce of diluted product/3000 cu. ft. This amount was doubled to 2 ounces of HPW (diluted at 1:32 )/3000 cu. ft. to insure thorough coverage. Whitefly larvae were killed when HPW was applied on a weekly schedule. The rate of kill was better than the control, but increased frequency gave significantly better results. Zero-hour re-entry allows growers to increase the frequency with minimal disruption to production activities.

For these reasons, we recommend applying HPW Insect Repellent using normal spray equipment rather than low-volume applicators. However, those preferring to use a low-volume applicator should mix HPW at a rate of 1:32 . Applications should be made every three to four days until control is achieved. To maintain control, application frequency should be reduced to weekly, and then biweekly based on insect monitoring. (Those using normal equipment should follow label directions.)
