Pea moth (Laspeyresia nigricana Steph.) is a major pest of integrated and ecological crops of pea in Poland, especially in south-eastern regions, were every year it causes high economic losses in the crop. Effective pea plants protection against pea moth is possible only in short period of time – from the caterpillar's hatch from eggs to the moment of biting into to the pods. Field experiments testing DiPel DF in studied doses – 0.5 and 1.0 kg/ha (in 2007) and 0.5, 0.75 and 1.0 kg/ha (in 2008), against pea moth on pea, were carried out in 2007 and 2008, on experimental fields belonging to Research Institute of Vegetable Crops in Skierniewice and on the farm belonging to horticultural college in Powiercie. Nomolt 150 SC, at the dose 0.2 l/ha, was used as a standard compound. Spraying liquids were applied once, when first hatching caterpillars of pea moth were observed on plants. DiPel DF at doses 0.75 and 1.0 kg/ha showed very good effectiveness in pea plants protection against pea moth.
