Itronics Inc. (OTCBB:ITRO) today reported that its subsidiary, Itronics Metallurgical, Inc., has obtained excellent results from a GOLD'n GRO fertilizer field application trial that demonstrates a reduction in sun damage to tomatoes compared to standard grower practice.

"The test was conducted specifically to determine if GOLD'n GRO products would work as part of a proprietary sunscreen product for tomatoes," said Dr. John Whitney, Itronics President.

In the trial, two GOLD'n GRO products were blended with a sunscreen product developed for use on tomatoes. The blended product reduced the leaf curl that occurs during the hot summer days in the Central Valley of California. Leaf curl exposes the tomato fruit on the plants to the sun and can severely damage them, causing the loss of 20 percent or more of a grower's crop. The proprietary
blended product successfully reduced sun damage in several thousand acres of tomatoes in late June and July.

"Only a small amount of GOLD'n GRO products, less than two quarts per acre, are needed to be combined with the sunscreen product, making this a very economical program for the tomato growers," said Dr. Whitney.

According to U.S. Department of Agricultural statistics, there are approximately 125,370 acres of tomatoes grown nationally and the value of the crop is about $1.25 billion, or $9,968 per acre. California has some 32,000 acres of tomatoes.

Itronics Metallurgical sells its high performance GOLD'n GRO liquid fertilizer, which can be used for lawns and plants, and its popular Silver Nevada Miner bars, a souvenir of the Silver State, through its shopping cart catalog at the Company's Web site http://www.itronics.com. Through a proprietary technology, Itronics Metallurgical extracts silver and other toxic metals from liquid
photographic waste and manufactures environmentally beneficial liquid fertilizers from the remaining material. The facility in Reno, Nevada is believed to be the only commercial plant in the world that can accomplish this.

Itronics Inc. is one of Nevada's leading process technology development companies and a world leader in photochemical recycling. Headquartered in Reno, Nevada, it specializes in recycling technology development, photobyproduct recycling, silver refining, and technical services for the mining and recycling industries.
