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.

문제 정의
Previous studies mostly demonstrated that kill-rate increased when sprayed more than twice. This research suggests that an effective control of aphids was possible by applying it once in every growth stages of the pepper. Application of SP alone demonstrated 40~77% kill-rate according to its concentration.
The high-temperature pests such as OTB, greenhouse whitefly, aphids, mites and so on are rampant in rain-shelter cultivation during hot periods. This study aimed to evaluate the effective concentration of organic farm inputs against the high-temperature pests, namely, OTBs and aphids in peppers, and greenhouse whitefly in tomatoes.
This study was carried out to determine the optimal concentration of agricultural organic materials using sulfur and oil for the insect pest control in pepper and tomato cultivation. The aphid control in pepper was complete by applications of SP+OP (0.
제안 방법
We searched for an effective control method for greenhouse whiteflies that occurred naturally in the test plot. We tested with SP (0.33, 0.25, 0.20, 0.17%), OP (2.00, 1.00, 0.50, 0.33%), SP+OP (0.33+2.00, 0.25+1.00, 0.20+0.50, 0.17+0.33%), and investigated its kill-rate after one day. Triple repetition of randomized block design was used for allocation of test plots.
” Seeds were sown on Mar 25 in Wanju county, transplanted on May 29. We tried to find effective recipe against OTBs and aphids by trying: SP (0.33, 0.25, 0.20, 0.17%), OP (2.00, 1.00, 0.50, 0.33%), SP+OPl (0.33+2.00, 0.25+1.00, 0.20+0.50, 0.17+0.33%), OP+GLE (1+1%), SP+OP+GLE (0.25+1+1%), SP+OP+GLE (0.25+1+0.50%). They were repeatedly sprayed and the kill-rate for aphids and OTBs was investigated after a day.

This test was carried out on the tomato variety “Minichal”. Tomato seeds were sown in Wanju district on March 25 and transplanted on May 27. We searched for an effective control method for greenhouse whiteflies that occurred naturally in the test plot.

The results of each parameter in all three applications were subjected to analysis of variance, and treatment means were compared by Duncan’s multiple range test (DMRT) at the 5% probability level.
성능/효과
and all the treatment of SP+OP. As the results, SP+OP (0.17+0.33%) treatment was the most economical combination when considering operating cost.
The aphid control in pepper was complete by applications of SP+OP (0.25+1.0%) in the early growth stage and the control value was above 98.1% by the application of OP+GLE (1.0+1.0%), SP+OP+GLE (0.25+1.0+1.0%), SP+OP+GLE (0.25+1.0+0.5%) in the middle to late growth stage while showing 0% in the control treatment.
후속연구
Although many reports earlier mentioned, there are not any researches on prevention of insect pest problem in tomatoes such as greenhouse whiteflies. Our results showing high kill-rate of this pest demonstrate that this natural pesticide utilizing sulfur and oil has high potential and needs further research.
