ABSTRACK
The objectives of this research is to know the influ- of frequency and dose of Tamaron application to ence control Diamondback on cabbage. This research was carried out at Kopeng Village, District Getasan, in the Region of Semarang from Oktober 11, 1994 until Desember 30, 1994. The soil type is Regosol, it's elevation is 1500 meter above sea level.
The factorial (4 x 4) experiment was arranged in Randomized Completly Block Design (RCBD) with three repli- cates. Frequency of spraying 0, 14,7 and 5 days periode combined to dose of Tamaron 0; 0,6; 0,9 and 1,2 liter hectar. per
Tamaron application might control attacking intensity number of egg and number of larvae consecutively at, 0,9 liter/14 days, 0,9 liter/5 days and 1,2 liter/5 days per hectar.
The highest yields is found at 0,9 liter/7 days. Interaction between frequency and dose of application found on attacking intensity, number of egg, crop and fresh weight of straw. weight is of
