This work was to obtain basic data for effective forecasting and control of plant diseases, insect pests and weeds. Plant diseases and insect pests occurring on new crops grown in Korea were surveyed for three years and identified based on their morphological characteristics and molecular data. Sixty two isolates of the genus Phomopsis causing fruits rot, die-back and cankers were obtained from 6 fruit trees, blueberry, pear trees, grapevines, jujube trees, persimmon trees and peach trees. They were identified as P. vaccinii, D. medusaea, P. conorum, D. eres, and P. liquidambari and unknown species based on sequences of the rDNA-internal transcribed spacer (ITS) regions. One hundred six isolates of the genus Xanthomonas obtained from different crops were identified as 27species and 79 pathovars based on the sequences of 23S rRNA, and 9 PCR primer sets for diagnosis of certain Xanthomonas species and pathovars were developed. Plant pathogens occurring on 9 introduced plants and 51 wild plants indigenous to Korea were investigated and 29 and 78 plant diseases were listed, respectively. Insect pests on 10 introduced plants and 10 wild plants surveyed were identified as 86 and 19 species, respectively. The subfamilies, Mirinae, Orthotylinae, Bryocorinae, Phylinae and Deraeocorinae in the family Miridae were listed which contained 49, 4, 3, 18 and 13 species, respectively. Among the 301 soybean fields surveyed, fields infected with soybean cyst nematode was estimated to be 85% and Heterodera glycines was identified as the main causal agent. Threshold population levels for cysts of the nematode per 100 g of soil was over 25 cysts. Twenty nine major gramineous weeds occurring on agricultural lands were identified based on the their qualitative and quantitative traits at seedling stage. To diagnose plant diseases occurring in the fields, diseased plants were received from farms for three years. The diagnosis numbers of fungal, bacterial and viral diseases and others consisted of 127, 24, 166 and 73, respectively. To computerize the information and data of plant diseases, photos and data related with diseases occurring on fruit trees, flowering plants, and medicinal plants were computerized and the information is now available on the NAAS website.
