Abstract

The efficiency of water and acetone extracts of radish Raphanus raphanistrum L. and turnip Brassica rape were tested separately and their mixtures with some hiopestiddes (Protecto Siosect) and an insect growth regulator (Runner) agnist 5asamia crelica throughout early summer season 2009. Data demonstrated that treatment with Runner alone, mixture of water radish extract and Protects achieved the highest percentage reduction in number of Sesanda aenea egg-masses, number of larvae, also the for mentioned treatments achieved the highest percentage reduction of plants containing perforated leaves and dead hearts. In addition the highest yield was obtained as a result of treating plants with the previously mentioned treatments. Data showed that there were significant negative correlation between yield and each of 5. o-ebrca traits.
