Greenleaf Technologies was founded in 1985 by Bill Smart with the idea of bringing high tech spray equipment to the market.

Bill Smart spent his whole life developing, tinkering with and promoting advanced fluid handling technology. If not destroyed by Hurricane Katrina, his 2000 square feet workshop might have served as a museum of his ideas for unique and innovative spray systems.

In 1995, a partnership was formed between Agrotop GmbH and Greenleaf Technologies whereby Greenleaf would promote and distribute the Agrotop Spray Technology product line in North America.

 

Steffen Graef of Agrotop developed the TurboDrop® nozzle in 1993 in response to the market need for an agricultural spray nozzle that would provide a combination of canopy penetration and coverage with contact chemicals that was previously not available. The high pressure TurboDrop® Venturi nozzle was born!

An additional advantage of the TurboDrop® design was its superior drift control even at high pressures. With the rapid growth of GMO crops and particularly glyphosate tolerant ones, spray drift management was becoming extremely important.

In 1998, the TDXL medium pressure TurboDrop® Venturi Nozzle was introduced to provide a more compact, economical, multi-purpose, user-friendly air injection nozzle to the North American market. Sales on the XL series have grown every year since.

Introduced in 2000, the AirMix nozzle was developed to provide a low pressure entry level Venturi nozzle, primarily with the European market in mind. An acid resistant version has found a niche in low pH applications in the U.S. Other versions have also been introduced.

In response to the Asian Soybean Rust scare of 2005, Greenleaf Technologies introduced the TurboDrop® TwinFan nozzle. Designed to deliver Medium-Fine (200-300 micron) droplets for soybean fungicides the TDTF utilizes a TwinCap with two different spray tips. The forward spray is 110° and delivers fine droplets (at ~ 80-120 psi) while the rear spray is 80° and produces Medium droplets (at 80-120 psi). More flow is directed rearward, with the 80° tip, to aid in canopy penetration. The air injected TurboDrop® TwinFan has proven useful for a variety of coverage critical applications.

In 2007, a variable rate version of the TurboDrop® nozzle was introduced on a limited basis, primarily for cotton applications with plant growth regulators and defoliants. It is offered in a single fan and a TwinFan version, and can deliver a 3x flow rate range. A new streaming fertilizer version was introduced in 2009.

The TurboDrop nozzle has proven to be one of the most innovative and versatile advancements for spraying plant protection products introduced in the last 50 years. It is used around the world on all types of spray equipment in the widest variety of applications.
