Research on Control of Pyrethrum against the Tomato Disease CMV Caused by Aphids

Tomatoes are the important crop in India and it is being attacked by a group of sucking pest during its
various stages. This crop is damaged by about 30 species of insects of various species like aphids,
whitefly, leafhopper and thrips etc. At present many pesticides/insecticides are being used for the
control of aphids in plants and crops. Undoubtedly pesticides kill aphids but also give many harmful
impacts on the plants as well as on the environment also. Insecticides are dispersed ubiquitously in
the environment and posed a serious problem to the ecosystem, due to their toxicity and ability to
accumulate in the biota. So, the need of the hour is to make an ecofriendly insecticide which reduce
the number of insects of the plant but do not harm the environment. Soap based pesticides have
improved efficacy against insect pest. The environmentally friendly soap based pesticides have
improved residuality, short and long term efficacy against both immature and adult pests and
improved safety for both humans and plants. An economically viable product is synthesised by using
,integrated pest management strategy., a soap based insecticide (potassium laurate and potassium
myristate ) and pyrethrum of various concentrations against a tomato plant disease named cucumber
mosaic virus (CMV), caused by aphids. On comparing the efficacy of both eco-friendly mixture it ,is,
concluded that the mixture of potassium laurate and pyrethrum is more effective as compared to the
mixture of potassium myristate and pyrethrum against the tomato disease named CMV caused by
aphids.
