| Abstract: | A field trial and demonstration, and indoor and outdoor tests showed that soil fumigation with SMDC (32.7%) at the rate of 50 ml/m2 can effectively control the common weeds in tobacco seedbeds, its controlling effect being comparable to that of methyl bromide (86.1%), Compared with control by hand, soil fumigation saved labor by 84.3%. Since no significant difference in weed control was observed between the three rates used in the study (50, 75 and 100 ml/m2), the rates of 50ml/m2 - 75 ml/m2 are recommended. SMDC also appeared highly effective in the control of cutworm in the seedbeds, its controlling effect being 88.6% and, like methyl bromide, killed root - knot nematodes in the 0 cm - 20 cm soil layer. The chemical proved safe for the germinating tobacco seeds and the persons who did the application. It is simple to use and low in cost, for it only requires mulching of the seedbed with a plastic film after chemical application. |
