Narkiewicz Jodko J.
In 1989-1993 field experiments on the performance of NTN 350 FS (Imidacloprid) and Marshal 250 DS (Carbosulfan) as seed treatment for the control of onion fly were carried out in central Poland on sandy loamy soil, containing 1.3 percent of humus. Each experiment consisted of four replicates in a randomized block design. The area of one plot covered 14 square meter. In order to determine the effect of different treatments for onion fly control, the performance was assessed at 10 days intervals after onion emergence by counting and removing damaged plant in each plot. On the basis of three years of experiments it can be concluded that both Marshal 250 DS and NTN 350 FS are very promising insecticides for the control of onion fly. Marshal 250 DS is registered already in Poland and in 1993 was applied with good success on over 10.000 hectares of onion. The recommended rate is 70 g of Marshal 250 DS as a product per 1 kg of onion seed. NTN 350 FS at present is in the last stage of registration and will be recommended in the rates from 50 to 60 ml of product per 1 kg of onion seed. The above experiments shoved seed treatment to be the most economical form of applying insecticides for onion fly control. This method is also least harmful to the environment.
