Cucumbers (Table 21). There are registered field and glasshouse uses on cucurbits in Spain (2-3 x 0.18 kg ai/ha, 3-day PHI), glasshouse uses on cucumbers and gherkins in The Netherlands (3-5 x 0.23 kg ai/ha, 3-day PHI), and field uses on cucumbers and gherkins in Jordan (0.0075 kg ai/hl, 3-day PHI). In Saudi Arabia 2 field applications with 0.011 kg ai/hl are used on cucumbers.
Three indoor trials were carried out in Germany. The residues after 3 days were 0.03 and 0.07 mg/kg from approximately 3 x 0.09 kg ai/ha, and 0.14 mg/kg from 3 x 0.18 kg. In two field trials in Italy, where 3 x 0.075 kg ai/ha were applied, the residues after 3 days were 0.02 and 0.19 mg/kg.
