Insects and nematodes associated with crops growing in plastic film houses were surveyed throughout the southern part of Korea at Jinju, Jiphyeon, Geumsan, Hapcheon, Changyeong, Namji, Milyang, Kimhae, Busan, Sooncheon and Gwangyang from December of 1984 to December of 1985. The phytonematodes representing six families, nine genera and nine species, and the insects representing four orders, seventeen families, twenty-three genera and twenty-four species were identified. The mite also caused problem on the leaves of strawberry and watermelon. Of these Meloidogyne incognita and Aphis gossyphii were most important ones. Aphelenchoides fragariae and M. hapla, however dominant nematodes on strawberry. M. incognita was always detected from pepper plants which were heavily infected with Phytophthora capsici. Tomato roots were readily infected with root-knot nematodes in non-sterilized upland surface soil. However, tomato were growing-vigorouly free from nematode damage in the upland surface soil treated by nematicide or in the paddy soil. A few galls were developed even in the upland subsoil at 60cm below surface. Soil salinity affected profoundly the host-root-knot nematode interaction: the numerous galls were developed on the tomato roots at EC
followed by 4mS and 2mS, but few galls were at 6mS.

Korean journal of applied entomology, volume 26, issue 4, 1987, Pages 203~207
Studies were conducted to investigate the race distribution of soybean cyst nematode (Heterodera glycines Ichinohe) in Korea. The results are abstracted as follows. The soybean cyst nematode populations collected from Kangwon Province were identified as races 1 and 3; the nematode populations collected from Kyunggi Province were identified as race 3, 5 and c and those collected from Chungnam Province were identified as races 1 and 5. From the total 21 populations 11 populations or 52.4% of the total were race 1; 6 populations or 28.6% of the total were race 5; 3 populations or 14.3% of the total were race 3 and one population or 4.8% of the total were race c. Soybean cyst nematode populations from the same district, at least from the same 'myeon' district were identified as same race. Of these 4, race 3 has not been recorded in Korea yet.

The optimum temperature range for conidial germination of Pyriculacia oryzae on a slide glass was
, at which at least four hours of leaf wetness period was required to germinate. Conidial germination was significantly reduced under dry conditions (relative humidity<85%) at
but not at lower temperature (18, 22, 26,
). Number of lesions developed were greater at
than at other temperature tested. The average leaf wetness period required for production of a lesion per plant was 22 hours at
, 16 hours at
, 10 hours at
, and 8 hours at
. Less than one lesion per plant occurred at
even under 24 hours of leaf wetness period. The time period between inoculation and lesion appearance was
. The time period required for lesion appearance after inoculation was not affected by leaf wetness period and relative humidity. Lesion length increased most rapidly at
during the first four days after lesion appearance. Thereater, the rate of increase in lesion length was geratest at
. The average increment of lesion length per day when relative humidity was greater than 90% was 0.7mm at
, 1mm at
, and 0.8mm at
. When relative humidity was less than 85%, the increments of lesion length per day were approximately
of those under humid conditions (relative humidity>90%) at all temperature regimes except
. Relative humidity did not significantly affected lesion length at

In order to study the biological control of soil-borne disease of sesame, antagonistic isolates of Trichoderma , Bacillus sand streptomyces to Fusarium oxysporum and Rhizoctonia solani were isolated from the rhizosphere soils of sesame plants and some other habitats. Out of the isolates of microorganisms collected a strain of Trichoderma viride was selected as a biological control agent for the study and its effect on the control of damping-off and the seedling growth of sesame was investigated. The results obtained are as follows: 26 percents of Bacillus spp. isolated from the rhizosphere soil of sesame plants showed antagonism to two pathogenic fungi. Important species were B. Subtilis and B. polymyxa. Streptomyces species isolated from the rhizosphere soils of sesame lysed the cell wall of hyphae and conidia of F. oxysporum and reduced conspicuously the formation of macroconidia and chlamydospores of the fungus. 84 percents of Trichoderma spp. isolated from the rhizosphere soil of sesame plants were antagonistic to F. oxysporum and 60 percents of the isolates were antagonistic to both F. oxysporum and R. solani. Trichoderma viride TV-192 selected from antagonistic isolates of Trichoderma spp. was highly antagonistic to F. oxysporum and soil treatment with the isolate reduced notably damping-off of sesame. T. viride TV-192 showed better growth in crushed rice straw, barley straw and sawdust media than F. oxysporum. Sawdust was selective for the growth of T. viride. Supplementation of wheat bran and mixtures of wheat bran and sawdust inoculated with T. viride TV-192 in the soil reduced remarkably damping-off of sesame by F. oxysporum but high density of the fungus TV-192 caused the inhibition of seed germination and seedling growth of sesame. Inhibitory effects of Trichoderma species on seed germination and seedling growth of sesame were different according to the isolates of the fungus. Normal sesame seedlings on the bed treated with the fungus showed better growth than not treated seedlings.

Yoon, J.T. ; Lee, J.T. ;
Korean journal of applied entomology, volume 26, issue 4, 1987, Pages 239~244
This studies was carried out to find the effect of inorganic matters of Apple Leaves on the occurrence of Alternaria leaf spot and calicium compounds on mycelial growth of Alternaria mali. Diseased leaf rate of Alternaria leaf spot of susceptible apple varieties was 84.8%, moderate resistant 8.1% and resistant 0.3% respectively and in No. of lesion per leaf, the tendency was same. CaO contents of apple leaves was contained much in the resistant varieties than susceptible one. It was estimated that calcium is one of factors on resistance to apple leaf spot by the results of relations among CaO contents and diseased leaf rate from July to August and No. of lesion per leaf was correlated significantly as r=-0.551, r=-0.585, -0.485 but in T-N,
, there was no difference among varieties. Then, growth of Alternaria mali was possible in the media of which pH ranged up to
, and calcium has effect of inhibition on growth of Alternaria mali.
Effect of Apple Leaf Hair Density on the Occurrence and Infection of Alternaria Leaf Spot Caused by Alternaria mali Roberts
Yoon, J.T. ; Lee, J.T. ;
Korean journal of applied entomology, volume 26, issue 4, 1987, Pages 245~249
In the 82 apple varieties tested, the distribution of varieties grouped on the damage degree to Alternaria leaf spot were 15 varieties(l8.3%), which damaged above 50%, and 51 varieties(62.2%) damaged below 5%. Susceptible varieties to Alternaria leaf spot were Raritan, Indo, Winesap and Starkrimson, moderately resistant varieties Sekaiichi and Starking, and resistant Jonathan, Tsugaru, Molliies, Jonagold, Gala etc. The leaf hair density on the backside of leaf were rarer inresistant varieties than susceptible one. In inoculation test, penetration and infection of Alternaria mali were easier on the backside than surface of apple leaf at the same varity, and infection rate with Alternaria mali were higher at removal treatment than non-removal one of leaf hairs, so we can guess that leaf hair are related to resistance of variety to Alternaria mali.
Effects of Cultural Methods on Infection by Rhizoctonia Disease (Rhizoctonia solani
) and Yield of Potato (Solanum tuberosum L.)
Park, C.S. ; Hahm, Y.I. ; Sin, G.Y. ;
Korean journal of applied entomology, volume 26, issue 4, 1987, Pages 251~255
This study was conducted to investigate the effects of cultural methods on infection by Rhizoctonia disease(Rhizoctonia solani
) of potato (Solanum tuberosum L.). Two potato cultivars, i.e., Irish Cobbler and Superior were planted in 1984 at the Alpine Experiment Station and 4 cultural methods were used in Combinations or separately. The deeper planting showed the later germination of sprout. The degree of infection on underground stems didn't show any differences between the treatments, but the yield was higher in deeper planting. When seed tubers were planted on April 28 the underground stems showed severely discolourated epidermis comparing to later planting, consequently the yield was low. The glazed chitting tubers produced healthy sprouts comparing to the untreated tubers, consequently the yield was also increased. The density of sclerotia on tuber skin was remarkably increased between 6 to 15days of delayed digging after haulm killing. Underground stems of Irish Cobbler were easily discolourated by the disease, where-as the density of sclerotia was higher on tuberskin of Superior than of Irish Cobbler.

Doshi, Anil ; Mathur, Sneh ;
Korean journal of applied entomology, volume 26, issue 4, 1987, Pages 261~265
Three diffeerent types of symptoms were observed according to the pathogen associated with the rhizomes. The maximum rotting was observed in case when Pythium aphanidermatum was inoculated first followed by Fusarium solani. There was no interaction in case of root knot nematode Meloidogyne incognita and Pythium aphanidermatum. Average per cent germination of the rhizomes were increased significantly in each treatment and maximum in case of Alliette(.25%). The per cent pre & post drenching rotting was minimum in case of Alliette, Burgandy mixture, Dithane-M 45 and Difolatan. These fungicides also increase the yield of rhizome significantly.

Cheema H.S. ; Chakravarti B.P. ; Lal Thakore B.B. ;
Korean journal of applied entomology, volume 26, issue 4, 1987, Pages 269~272
Effects of dithane flowable and dithane M-45 on the control of opium poppy downy mildew were examined under field conditions. Application of these two fungicides significantly reduced the disease and increased latex yield, compared to other non-systemic fungicides.
The Use of AM-toxin in Monitoring the Numbers of Air-borne Spores of Alternaria mali Causing Leaf Spot in Apple Orchards
Yu, Seung-Hun ; Shim, Hyeong-Kwon ; Park, Jong-Seong ;
Korean journal of applied entomology, volume 26, issue 4, 1987, Pages 273~275
Changes in the numbers of air-borne spores of Alternaria mali causing the Alternaria leaf spot of apple were investigated in apple orchards, by monitoring their AM- toxin(host-specific toxin) producing ability. Most of the air-borne Alternaria in apple orchards were not AM-toxin producers. In culture, only about 2% of Alternaria isolates from a commercially managed apple orchards produced the toxin that was highly toxic only to susceptible leaves.
