Anthurium decline, caused by Radopholus similis, is a chronic problem which reduces yields of Anthurium andraeanum by 50 percent. The nematode may cost growers in excess of $1.5 million annually. The industry has relied upon Nemacur as the primary means of reducing the burrowing nematode populations since the loss of a Vydate registration. DiTera, a fungal-based nematicide may provide an alternative to Nemacur in anthurium. The objective of this research is to determine optimal rates and appropriate application frequency of DiTera for burrowing nematode control in anthurium.

Project goals and objectives
1). Determine the optimal rate of DiTera ES for field control of burrowing nematodes.
2). Determine appropriate application frequency of DiTera ES for control of urrowing nematode in anthurium.

DiTera was proven to be effective in reducing anthruium decline. DiTera gave the best control when applied at 30 lb/acre (34 kg/ha) once every three months. Generally, frequent applications of DiTera at a lower rate is best. Quarterly application of 30 lb/acre (34 kg/ha) is more effective than seimiannual application at 60 lb/acre (67 kg/ha).
