Abstract:
Chrysanthemum (Dendranthema grandiflora Borkh), known as the "queen of the east" and cultivated for commercial purposes in all over the world. Chrysanthemums are cultivated in India for use as cut flowers, loose flowers, potted plants and garden boundary plants. The sucking insect pests are the limiting factors for higher production as well as good quality of flowers. Among the various insect pests, Macrosiphoniella sanborni (Gillette) (Hemiptera: Aphididae) is the main pest responsible for the damage to chrysanthemums. For the sustainable management of aphids without causing any adverse effect on crop and natural enemies study carried out with foliar application of insecticides at different doses for the two successive years 2018-19 & 2019-20. Results revealed that the among different doses of insecticides flonicamid 50 WG @ 0.019% found most effective against M. sanborni followed by acephate 50% + imidacloprid 1.8 SP @ 0.064%. As well as this treatments also reflected maximum yield of chrysanthemum flower.
