Effect of Sumagic on growth of three bedding plants
1990
Wang, X. | Jiao, J. | Tsujita, M.J.
Plants of salvia, impatiens and petunia were treated with Sumagic as both spray and drench at 0.02 to 0.4 mg active ingredient (ai.)/pot. Sumagic treatments resulted in more compact plants in all three species compared with control. Sumagic drench was more effective than spray in impatiens, but was similar to spray in petunia and salvia. Sumagic generally reduced leaf area and leaf dry weight but it increased the specific leaf weight in salvia. At high rates, Sumagic increased chlorophyll content in all three species on a leaf area basis. On a dry weight basis, however, Sumagic only increased the chlorophyll content in impatiens.
