Resumo: | Check the state of infestation  • When the potato plants start to emerge, walk the field every 7 days in a straight line and check plants at regular intervals.  • If clusters of eggs are found on more than every third plant, apply Novodor four days after discovering the first clusters.  Apply the agent  • Dissolve 5 l of Novodor in 500 l of water per hectare of potatoes.  • Novodor can be applied together with copper products.  Optimal conditions:  • The potato beetles are still in an early larval stage (L1 to L2).  • Temperature between 15 °C and 25 °C.  • Avoid direct sunlight: spray late in the evening or when the sky is overcast.  • No rain is due within 8 hours after spraying.  Comments  • After a successful treatment, the larvae will turn black after a few days.  • If the effect is insufficient, the larvae will stay mobile. In this case, the treatment should be repeated within the following 10 days.
