TAILIEUCHUNG - Chemical management of whiteflies in sunflower

Among the insecticides evaluated, diafenthiuron 50 % WP @ 1 g/l and triazophos 40 % EC @ 2 ml/l were found to be best and most effective against whitefly in sunflower. This was reflected in the total yield of diafenthiuron 50 % WP (1346 kg/ha) and triazophos 40 % EC (1301 kg/ ha) and these two treatments were on par with each other. Next superior treatments in order of priority were flonicamid 50 % WG > fipronil 5 % SC > buprofezin 25 % SC > clothianidin 50 % WG > profenophos 50 % EC > azadirachtin %. | 2019 8 4 2885-2890 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 04 2019 Journal homepage http Original Research Article https Chemical Management of Whiteflies in Sunflower Praveen B.

Introduction Sunflower Helianthus annuus L. popularly known as Surajmukhi as it follows the movement of the sun. It belongs to the genus Helianthus family Asteraceae Compositae . The name has its origin in Greek Helios means Sun and Anthois means flower . It is native to southern parts of USA and Mexico Heiser 1951 . Sunflower is an important oilseed crop in India. Sunflower originated in Southern United States and Mexico from where it was introduced into Europe and later into former Union of Soviet Socialist Republics USSR . Majority of the present day varieties are grown all over the world. The crop originated from former USSR. In India sunflower crop was introduced in 1969. In India sunflower is being grown over an area of m ha with a production of million tonnes and the productivity of 643 kg per ha. In Karnataka sunflower is being grown over an area of m ha with a production of million tonnes
