除草劑에 衣한 복숭아果樹園의 雜草 防除試驗

다국어 초록 (Multilingual Abstract)

Weeding in peach orchard, especially in spring and summer, is one of the most
serious problems in Chonnam area. Control trials with several herbicides such as
Paracol 40 E.C Paraquat 24.5 E.C and Roundup 41 E.C were carried out on the
field as well as with the potted weeds for two years from 1976 to 1977.
The results are summarized as follows:
A. Field test
1. Weeds in peach orchard of the experimental farm, Chonnam National University
were 12 species of 9 families, of which Artemisia vulgaris, Erigeron canadensis
Humulus japonicus, Alopeculus aequalis. Rumex crispus and Polygonum
hydropiper were the predominant ones.
2. All the weeds but Rumex crispus were effectively controlled by paracol or Paraquat.
Withering ratio of more than 95% was obtained by the application of 80g/
10a of Paracol or by 100g/10a of Paraquat.
3. Roundup was proved to be less effective than the other two herbicides in controlling
orchard weeds. Even though more than 95% of Artemisia vulgalris and Humulus
japonicus could be controlled by 200g/10a, of Roundup only 73.1% of Erigeron
eanadensis, 81. 9% of Polygonum hydropiper, 70.4% of Rumex crispus, 58.8%
of Alopeculμs aequalis even by 300g/10a of Roundup.
B. Pot test
1. Three kinds of herbicides. Paracol, Paraquat and Roundup were applied at different
growing stages; seedling. vigorous vegetative growth, and flower bud formation.
The difference in weeding effect among herbicides was not found. However,
flower bud formation stage was proved to be the most appropriate time for
herbicide application. The highest withering ratio of more than 81% was obtained
from the application at flower bud formation stage compared to around 70% from
those at other two stages.
2. Double applications of any herbicides resulted in about 75% withering ratios, which
were higher than those (about 62%) from single application.
3. Among the treatments resulted in withering ratios of more than 95%, single application
at flower bud formation stage or double applications at seedling stage with
80g/10a of Paracol, single application at flower bud formation stage or double
applications at seedling stage with l00g/10a of Paraquat, and single application with ‘
3OOg/10a at flower bud formation 훌ge or double applications at seedling stage
with lOOg/10a of Roundup .weπ considered as the effecient methods in controlling
weeds in Peach orchard.
