Spray application rate, equipment affect pest management in greenhouse ivy plants
Date:3/31/2010

nt was conducted in a commercial greenhouse during January and February 2008 using the ivy cultivar Hedera algeriensis cv. Montgomery (Hibb.). Two different spray application systems were tested: a spray gun equipped with a disc-core nozzle, and vertical spray booms mounted on a trolley. The effect of application rate, nozzle type, size and spray pressure, and the difference between the traditional spray gun and a vertical spray boom system were recorded. The full study was published in HortScience.

The scientists found that the spray system and application rate clearly influenced the system's effectiveness. "Evaluating the deposition results for the two crop zones reveals that the spray gun performed quite well on the runners", Nuyttens explained. "With this technique, the spray liquid was targeted from below to the easily accessible runners, which might explain the higher spray deposition on this part of the crop." For the sprays performed with the spray boom system, a significant difference was found between the lower and higher application rate. Because the concentration of tracer was the same for both application rates, doubling the application rate justifies the increase in spray depositions.

On the main crop canopy, the spray gun performed a lot worse", Nuyttens added. "Although the spray gun operated from the ground floor still performed best on the easily accessible crop zone with the runners, its performance in the more dense main crop canopy zone was inferior."

Summarizing the significance of the research, the researchers said that the experiment underlines that, besides the application rate, the spray application equipment is an important factor defining the spray deposition achieved when spraying ivy pot plants stored on hanging shelves in greenhouses.
