Studies on the ovicidal activity of some insecticides and acaricides on the winter eggs of the red fruit mite (Panonychus ulmi (Koch) Ehara)


, : Studies on the ovicidal activity of some insecticides and acaricides on the winter eggs of the red fruit mite (Panonychus ulmi (Koch) Ehara). Gradinarska i Lozarska Nauka 12(1): 41-46

In laboratory studies in Bulgaria to evaluate the effectiveness of various acaricidal and insecticidal compounds against the winter eggs of Panonychus ulmi (Koch), a preparation (Nissol) containing 35% N-methyl-N-(1-naphthyl)-2-fluoroacetamide was very effective at 0.1% against eggs that had been incubated at about 22 deg C and 80-90% R.H. for 4 days and at 0.2% against those incubated under these conditions for 4-7 days.
