Fungicide Pesticide Trifloxystrobin 50% + Difenoconazole 10% ECTrifloxystrobinTrifloxystrobin is a widely used fungicide that has EU approval for use. It has a low aqueous solubility, a low volatility and, based on its chemical properties, would not normally be expected to leach to groundwater. It would not be expected to be persistent in soil or water systems. It has a low mammalian oral toxicity but there is some evidence that it may cause negative reproduction or fertility effects. It is highly toxic to bird, fish and aquatic invertebrates, but less toxic to honeybees and earthworms.

Difenoconazole is a fungicide used for disease control in many fruits, vegetables, cereals and other field crops. Although potentially a mobile molecule it is unlikely to leach due to its low aqueous solubility. It does however have potential for particle bound transport. It is slightly volatile, persistent in soil and in the aquatic environment. There are some concerns regarding its potential for bioaccumulation. Moderately toxic to humans, mammals, birds and most aquatic organisms.
