Crane flies

Crane flies

The main species in Europe are the European crane fly, Tipula paludosa, and the marsh crane fly, Tipula oleracea. Their larvae cause the greatest damage in spring and early summer; however, they can only be controlled in the autumn when the young larvae have hatched. The decision-making criteria are the damage during the season and the number of empty puparia on the green. The best method of controlling young crane fly larvae is nemastar®. The soil temperature should be above 12 °C.

Application

Use nemastar® as soon as the majority of larvae have hatched – two weeks following the flight peak which is usually mid September. Dissolve the nematode powder in water, spray on the damp grass and water in lightly. The larvae are at a depth of 1-2 cm. The soil should be kept damp for the following two weeks.
