Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    COMPATIBILITY OF RECOMMENDED INSECTICIDES AND FUNGICIDES FOR THE MANAGEMENT OF MAJOR INSECT PESTS AND DISEASES OF PADDY
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) ANIL KUMAR, K; Dr. A. SITHA RAMA SARMA
    Studies on “COMPATIBILITY OF RECOMMENDED INSECTICIDES AND FUNGICIDES FOR THE MANAGEMENT OF MAJOR INSECT PESTS AND DISEASES OF PADDY” were conducted in the laboratory of the Department of Entomology and Agricultural College Farm, Agricultural College, Bapatla, Guntur District, Andhra Pradesh during 2014-15. In the investigations, seasonal incidence of insect pests and diseases of paddy, physical, chemical compatibility and biological efficacy of insecticides, fungicides alone and in combinations were studied. A bulk plot of 200 m2 and a light trap was maintained to study the seasonal incidence of pests of paddy during kharif, 2014. The leaf folder, Cnaphalocrosis medinalis L. infestation started during 39th standard week (September 24th- 30th) with 12.95 per cent per 50 hills and reached a peak level at 48th standard week (November 26th- December 2nd) with 18.31% and declined gradually to 8.10% in 49th standard week. The symptoms of rice leaf blast disease caused by Pyricularia oryzae appeared initially during 43rd standard week (October 22nd – 28th) with 1.55 per cent disease severity and reached a peak level at 48th standard week with 14.66% and decreased gradually to 2.55% at 51st standard week. In light trap the catches of brown plant hopper, Nilaparvata lugens L. started appearing from 25th October (15.00) and gradually increased and attained two peaks during 9th November (5400) and 3rd December (2145) respectively thereafter the population gradually decreased towards the end of the season. However the green leafhopper, Nephotettix virescens L. catches started appearing from 31st October (11.33), gradually increased and attained two peaks during 15th November (2328.67) and 15th December (4731.33) respectively and thereafter the population gradually declined. The leaf folder adults in light trap started appearing from 6th November (1.33) and attained peak at 12th December (20) and thereafter gradually decreased. No significant correlation between weather factors studied with brown planthopper catches and leaf folder infestation. However, green leafhopper catches showed a non-significant and negative correlation with maximum temperature and rainfall and significant and positive correlation with morning and evening relative humidity. Whereas the leaf folder adult catches in light trap showed a non- significant correlation with maximum temperature, minimum temperature, rainfall and significant and positive correlation with morning relative humidity. Leaf blast incidence showed a significant and negative correlation with maximum and minimum temperature but significantly positive correlation was observed with morning relative humidity. Laboratory experiment conducted in the Department of Entomology, Agricultural College, Bapatla to test the physical and chemical compatibility of insecticide and fungicide combinations. There was no formation of sediment at the bottom and the creamy layer at the top when insecticides and fungicides mixed in distilled water, tap water and standard hard water. The specific gravity values, pH and EC values also did not vary much. The experiment conducted in green house at Agricultural College, Bapatla to assess the phytotoxicity revealed that no phytotoxicity symptoms were observed when insecticides and fungicides mixed and applied to potted plants at recommended and higher dose (double). The per cent leaf injury was less than one implying the tested insecticides and fungicides are physically, chemically and biologically compatible with each other. From the field experiment conducted during kharif, 2014 in the College Farm, Agricultural College, Bapatla to evaluate the efficacy of foliar sprays of insecticides, fungicides alone and in combination against major pests of paddy. Chlorantraniliprole + isoprothiolane (0.3 ml l-1+1.5 ml l-1) emerged as the most effective treatment to control leaf folder infestation with 83.04 per cent leaf damage reduction over control followed by chlorantraniliprole (0.3 ml l-1) and chlorpyriphos (2.5 ml l-1) with 81.86 and 79.67%. With respect to leaf blast, tricyclazole (0.6 g l-1) was found superior over other treatments in reducing leaf blast severity with 74.13 per cent reduction of disease over control followed by isoprothiolane (1.5 ml l-1) with 69.42 per cent reduction of disease incidence over control. Significantly highest yield (5.39 t ha-1) was recorded in chlorantraniliprole + isoprothiolane (0.3 ml l-1+1.5 ml l-1) followed by all other combination, individual treatments. The untreated control recorded the lowest yield (2.00 t ha-1). There was no reduction in the efficacy of insecticides when mixed with fungicides and vice-versa against both leaf folder infestation and leaf blast severity.
