의약용 Capsuel에 넣은 입제형 살충제 BPMC, Carbofuran, Cartap, Chlorphenamidine-HCl, Cytrolane, Diazinon의 단일회 수도근부처리로서 수도 전생육기간에 걸친 이화멸충, 멸구, 매미충류 및 Virus 병의 방제효과를 검정하기 위해 포장시험을 실시하여 아래와 같은 결과를 얻었다. (1) 이화명충은 발생이 적었기 때문에 약제간에 큰 차이는 볼 수 없었지만 약제처리후 50일에서 이화명충 1화기 심고경율 Cartap 0, Carbofuran 0.1, Chlorphenamidine 0.4, Cytrolane 0.5, BPMC 1.8, Diazinon 2.2이었으며 2화기 백수율은 BPMC에서
During 1973 a field experiment was carried out to evaluate effectiveness of the root zone application of insecticides in medical gelatin capsules for control of several rice insect pests and dwarf virus disease. At three days after transplanting the capsules were pushed by hand about 2.5cm into the soil, near roots of Tongil rice plants. At the given day intervals number of leaf-and plant-hoppers on the hills were recorded by direct count, and dead hearts and white heads by stem borers and dwarf virus infected hills were observed in the experiment plots. Finally grain yields were measured. The percentages of dead hearts and white heads in all the plots were too low for evaluating the effectiveness of insecticides against the striped rice borers. Carbofuran of the insecticides tested was relatively effective against green rice leafhopper (Nephotettixcincticeps) and small brown planthopper (Laodelphax striatellus), although small number of insects on the hills were recorded. Relatively small number of white-backed planthopper (Sogatella furcifera) was occured in the BPMC and Diazinon treated plots. BPMC and Carbofuran were highly effective against the brown planthopper (Nilaparvata lugens) to 80 days after treatment. Incidence of dwarf virus disease was least in the plots of Carbofuran treatment. The highest grain yield was recorded in the plots treated with Carbofuran, and it seemed to be related with good protection from the dwarf virus disease and leaf-and plant-hoppers.
