Studies on the Eradication of Pedicularis spp., Alternate Host of White Pine Blister Rust with Several Herbicides <Jour. Kor. For. Soc.. 51: 51-55 1981> Authors Chang-Keun Yi, Hyun-Joong Kim, Woon-Hong Yeo
The study was conducted during 1975-1980 to evaluate the performance of several herbicides in controling alternate host, fPedicularis spp.., of white Ppne blister rust disease in forest stands. The results obtained were summarized as follows.
1) It was found that Roundup was effective and most suitable herbicide in the forest stands except that it accompanied some chemical injuries to neighboring plants. 2) As for the reduction density on the plot treated with Roundup was 100% and 65-91%, respectively when investigated one and two years after its treatment on Pedicularis spp. 3) Another four chemicals, e,4-D, Gramoxone, 2.4.5-T and Para-col killed stems and leaves of Pedicularis spp, at the year treated, but appeared again next spring. 4) Eradication effectiveness in terms of spraying season was proved to be that late August was better than late May or June.
