The Psila Protect range is an effective carrot rust fly solution for carrot, celery, parsnip and parsley root crops. 

The granules for Psila Protect are impregnated with onion oil and diffuse their odour, naturally repelling the carrot rust fly. Positioned in the Spring, the protection lasts all season!

 

Carrot Rust Flies lay eggs at the foot of the plants in the late afternoon and early evening when the humidity is high. The larvae penetrate the roots of the carrots and dig tunnels that damage the growth and quality of the vegetable. Two to three generations follow one another during the season.
