Claiming to have the only ceramic venturi nozzles on the market, Greenleaf Technologies introduces the TurboDrop TDCXL, with a life expectancy of 50,000 to 80,000 acres. The ceramic metering orifice is 10 times harder than stainless steel, say Greenleaf engineers. With a range of 30 to 150 psi, the TDCXL reduces drift by eliminating most of the small fines in spray and allows spraying in wind speeds twice those of conventional nozzles. The higher speed and larger, air-filled droplets give deeper penetration into the crop canopy and greater leaf surface coverage. Round metering orifices cut clogging potential. The nozzle can be taken apart by hand. Price: $15 per nozzle. Contact Greenleaf Technologies, Dept. Apply*, Box 1767, Covington, LA 70434, 800/881-4832, go to www.turbo drop.com or circle 403

Precision Laboratories has formulated two new marking foams to be used for the two basic types of marking equipment used on ag sprayers.

Enduron PSI drops more foam at higher operating pressures and application speeds in pressurized systems. Enduron XC is used at lower operating pressures that are commonly found in expansion chamber systems. The company claims that both formulations are heat and wind resistant and will last up to 50% longer than competitive marking foams. Contact Precision Laboratories Inc., Dept.
