How to Use
Delfin® WG can be applied with standard spray equipment.
Apply Delfin® WG when first larvae are observed. Young caterpillars are more susceptible than older ones. Repeat applications may be necessary to cover the hatching period. It is advisable to respray when new shoots develop.
Delfin® WG should be applied at a rate of 0.75 kg/ha per treatment and can be applied up to 6 times per season.
Delfin® WG is best applied early morning or in the evening if possible.
Spray volume should be high enough to give good crop coverage without runoff (150 - 1500 L/ha depending on planting density and crop size).
Delfin® WG should be stored in a cool, dry, frost-protected place. High humidity and temperatures over 30°C decrease the activity of the product.
Use pesticides safely, always read the label before use.

Delfin® WG is a biological insecticide used for the control of
Lepidoptera larvae. The product consists of a bacterial preparation
containing the spores and crystals of Bacillus thuringiensis
subspecies kurstaki. The insecticidal activities of Delfin® WG are
attributable to the afore mentioned crystals (crystalline proteins)
that are produced by Bt during sporulation. Once ingested, the
crystals dissolve in the insect's mid-gut, leading to the formation of
pores in the cell membrane. This causes the insect to stop feeding
and ultimately leads to full control of the pest.
Delfin® WG is considered safe to non-target organisms with no
negative effects against naturally occurring beneficial insects or
introduced macro biologicals.
