“…Thus, it is evident that the death of the insect vector occurs much more quickly than the minimum inoculation feeding period of the virus complex, and hence lowers the incidence of disease under field conditions. A similar result was also reported by Satapathy and Anjaneyulu (1984) in the case of cypermethrin.…”

“…The test cultivars were TN1 (susceptible) and Ratna (tolerant). Experimental design, spacing, fertilizer schedule, date of sowing and planting, induction of tungro disease incidence, sampling procedures and statistical analyses, were those used by Satapathy and Anjaneyulu (1984).…”

“…Cypermethrin, a synthetic pyrethroid, has been the most promising of various groups of insecticides tested in reducing the incidence of tungro disease (Satapathy and Anjaneyulu, 1984). We tested some more synthetic pyrethroids to determine the best ones.…”

The five synthetic pyrethroids cypermethrin-1, cypermethrin-2, deltamethrin, fenvalerate and FMC 54800, were evaluated under greenhouse and field conditions to determine their efficacy in preventing tungro infection and in reducing the incidence of tungro disease. Cypermethrin (1 and 2) and deltamethrin killed the vector, Nephotettix virescens, within 7 minutes and prevented tungro infection under greenhouse conditions; the performance of these insecticides was also better under field conditions. Grain yields were higher in plots treated with these insecticides than in the control plot, or in plots treated with other insecticides, in the cultivar Taichung Native 1. In the cultivar Ratna, these insecticides, plus fenvalerate and carbofuran (check insecticide), had an equivalent effect. The vector population in the plots treated with cypermethrin (1 and 2) and deltamethrin was eliminated. There was a negative correlation between the rate of tungro infection and grain yield, and a positive correlation between vector population and disease incidence.

“…There are many insecticides to control the green leafhoppers of rice as an insect pest but there are only a few insecticides to control it as a vector. In previous papers, we have shown that cypermethrin among emulsifiable insecticides (Satapathy and Anjaneyulu, 1984) and carbofuran among granular insecticides (Satapathy and Anjaneyulu, 1986) are very efficient in preventing tungro virus infection and management of the disease. In order to identify some more insecticides, we have evaluated some wettable powder insecticides with the objective of identifying insecticides that could prevent the virus infection by artificial inoculation under greenhouse conditions.…”
