Studies On Eco Friendly Management Of Stem Borer Chilo Partellus Swinhoe And Shoot Fly Atherigona Soccata Rondani On Maize Crop

Abstract

Maize is one of the most important cereal crop in the world agriculture economy both as food for man and feed for animals. It is also known as Queen of Cereals because of high yield potential. Maize (Zea mays L.) being the highest yielding cereal crop in the world, is of significant importance for countries like India, where rapidly increasing population has already out stripped the available food supplies. The high yield in maize could not be realized due to large number of insect pest attacking maize. More than 150 insect species damage the crop from sowing to crop harvest. The continuous cropping of maize during the kharif , rabi and spring seasons has led to a change in the insect-pest complex with the occurrence of Shoot fly (Atherigona soccata Rondani) in spring , Maize stem borer (Chilo partellus Swinhoe) in kharif and Pink stem borer (Sesamia inferens Walker) in rabi sown maize. To combat with this problem the present field investigation entitled, Studies on Eco-friendly management of stem borer, Chilo partellus (Swinhoe) and shoot fly, Atherigona soccata (Rondani) on maize crop (Zea mays L.) was carried out for two consecutive spring seasons i e 2015 and 2016 at Nawabgang farm Chandra Shekhar Azad University of Agriculture and Technology, Kanpur with sixteen treatment viz. No insecticide+ 0.0 Kg N/ha, imidacloprid 17.8SL+ 0.0 Kg N/ha, diflubenzuron 25WP+ 0.0 Kg N/ha, quinalphos 25EC+ 0.0 Kg N/ha, No insecticide+ 70 Kg N/ha, imidacloprid 17.8SL+ 70 Kg N/ha, diflubenzuron 25WP+ 70 Kg N/ha, quinalphos 25EC+ 70 Kg N/ha, No insecticide+ 80 Kg N/ha, imidacloprid 17.8SL+ 80 Kg N/ha, diflubenzuron 25WP+ 80 Kg N/ha, quinalphos 25EC+ 80 Kg N/ha, No insecticide+ 90 Kg N/ha, imidacloprid 17.8SL + 90 Kg N/ha, diflubenzuron 25WP+ 90 Kg newlineN/ha and quinalphos 25EC+ 90 Kg N/ha replicated thrice in factorial randomized block design newline newline
