Abstract

In field studies, the insecticides carbofuran(Furadan 3G) and diazion(3G) at the rate of 1,8 kg a.i./ha as a single side-furrowing treatment from March 13 to April 10(7 to 10 days intervals) were evaluated in terms of the control effects to the onion maggots(Hylemyia antique Meigen) and some phytotonic effects to the garlic plants. The treatments with carbofuran were significantly more effective in onion maggot control than the treatment with diazinon and untreated, and the earlier treatments the better control effects were obtained. Phytotonic effects only with carbofuran on garlic plants were of served as increases ranged $16.5\~23.2\%$ in plant heights, $22.0\~32.0\%$ in stem diameters and $15.5\~22.8\%$ in bulb diameters compared to the untreated. The greatest yield of garlics was resulted in the plots of Match-13 treatments with carbofuran, ca. 10,700kg/ha in the carbofuran treatment, ca. 5637kg/ha in the diazinon treatment and ca. 4728kg/ha in the untreated plots. The magnitude of yield increase of garlics in the plots treated with carbofuran was attributable to positively stimulate the growth response of garlic plants as well as the control effects to onion maggots.
