This experiment was carried out to determine the optimal concentration of agricultural organic materials using sulfur and oil for the insect pest control in pepper and cherry tomato cultivation. The control value of aphids and Oriental tobacco budworm (OTB) was examined one day after spraying with sulfur preparation (SP) (0.33~0.17%), oil preparations (OP) (2.00~0.33%), SP+OP, OP+ginkgo leaf extracts (GLE), SP+OP+GLE on the “Super Manidaa”pepper. The aphid control in pepper was complete by applications of SP+OP (0.25+1.00%) in the early growth stage and the control value was above 98.1% by the application of OP+GLE (1.00+1.00 %), SP+OP+GLE (0.25+1.0+1%), SP+OP+GLE (0.25+1.0+0.5%) in the middle to late growth stage while showing 0% in the control treatment. The OTB was completely controlled by the 3 times application with the high concentration of SP+OP (0.25+1.00%) in pepper cultivation. This result indicates that the oil and the sulfur preparations should be applied at low concentration before insect pests do not appeared, and then sprayed at the high concentration after they appear at pepper plant. The greenhouse whitefly in ‘Minichal’ tomatoes was completely controlled by three times application of SP (0.25~0.33), OP (1.0~2.00%). and all the treatment of SP+OP. However, continuous control with intervals of 1~3 days was considered favorable in the tomato plant. By the periodical control with agricultural organic materials using sulfur and oil, the greenhouse whitefly, which is a high-temperature insect pest, several moths of OTB did not occur at all. In conclusion, SP+OP (0.17%+0.33%) treatment was the most economical combination to control the aphid, OTB, and greenhouse whitefly in pepper and tomato cultivation when considering operating cost. In addition, we recommend that SP should not be sprayed on the plant shoots during the day time from July to August because of high temperature.

TThis study investigated the influence of AGH-Ringer (chelated organic minerals liquid fertilizer) on the growth, yield, and fruit quality of ‘Jukhyang’ strawberry in a hydroponic system. The results revealed that AGH-Ringer group led to significantly higher plant length than that of the control group, and that leaf length and leaf width increased with increasing leaf area. In addition, the fresh and dry weights of leaves and SPAD unit, which measures leaf color also showed a significant increase with AGH-Ringer. However, the length and dry weight of roots did not show significant differences when compared to the control group. In the fruit quality analysis, AGH-Ringer group did not show any difference in fruit length compared to the control group, but it increased both the fruit weight, which, along with the simultaneous increase in fruit width, increased the yield per strawberry. Furthermore, AGH-Ringer group strengthened the red skin color of the fruit, and resulted in significantly greater hardness than that of the control group, but did not have any effect on the soluble solid content and acidity. As shown in the results, the AGH-Ringer group resulted in lesser mineral content and lower to medium EC (electrical conductivity) in comparison to the inorganic mineral hydroponic fertilizer, which was used as a control. However, it increased the leaf growth, fruit weight, and yield, and improved the fruit quality by increasing the soluble solid content in the hydroponic system of ‘Jukhyang’ strawberry. Therefore, based on this study, AGH-Ringer is thought to be a more effective hydroponic fertilizer than the inorganic mineral hydroponic fertilizer. Moreover, the field experiment demonstrated
