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.

    SCREENING OF CERTAIN GENOTYPES OF BLACKGRAM (Vigna mungo L. Hepper), MONITORING AND INSECTICIDAL MANAGEMENT OF WHITEFLY Bemisia tabaci Gennadius
    (Acharya N.G. Ranga Agricultural University, 2017) JAKEER SHAREEF, S; RAMAKRISHNA RAO, A
    The present study entitled “Screening of certain genotypes of blackgram (Vigna mungo L. hepper), monitoring and insecticidal management of whitefly Bemisia tabaci Gennadius” was carried out during rabi 2016-17 at Department of Entomology, S. V. Agricultural College, Tirupati. The incidence of whitefly was observed from 3 rd standard (std.) week (3rd week of January) with a population of 0.16 nymphs/ trifoliate leaf during 1st date of sowing of LBG 623 in blackgram. Among all the three dates of sowing, peak incidence of whitefly population (10.58 nymphs /trifoliate leaf) was observed in 13th std. week (last week of March). Weather parameters like evening relative humidity, rainfall and wind speed showed negative association with whitefly incidence in terms of number of nymphs/trifoliate leaf while maximum temperature showed positive association with whitefly incidence. The multiple linear regression analysis revealed that all the weather factors together were responsible for 82 per cent (R2= 0.82) and 77.4 per cent (R2= 0.774) total variation in whitefly population in two blackgram varieties LBG 623 and PU 31 sown during January first fortnight (D1 ). Among these evening relative humidity, rainfall, sunshine hours and wind speed also could independently affect changes in whitefly population. Thirty-six blackgram genotypes including one susceptible check LBG-623 and one resistant check were selected for screening for resistance to whitefly and replicated thrice in a simple Randomized Block Design. The evaluation of different genotypes against whitefly under field conditions revealed that the genotypes with high trichome density i.e., PU-31 (43.50/cm2 ), TBG-104 Name of the Author : S. JAKEER SHAREEF Title of thesis : “SCREENING OF CERTAIN GENOTYPES OF BLACKGRAM (Vigna mungo L.

RAMAKRISHNA RAO University : ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY Year of submission : 2017 (43.20/cm2 ), GBG-1 (42.90/cm2 ) and GBG-103 (42.60/cm2 ) recorded less number of whitefly population viz., 2.83, 2.91, 3.03, 3.13 nymphs/ trifoliate leaf/ plant, respectively. The trichome density had highly significant negative correlation (r= - 0.951) with the population of whitefly nymphs. SCMR values are significantly negatively correlated with MYMV incidence (r= -0.700) as well as whitefly population (r= -0.871). Leaf thickness had non-significant negative influence (r= - 0.280) on whitefly population. Seed treatment with imidacloprid 600 FS @ 2.0 ml+4.0 ml water kg-1 seed was effective upto 30 DAS with more than 50.0 per cent reduction in the whitefly population over control. Among all the insecticides evaluated as foliar sprays, buprofezin 25 SC @ 1.5 ml L-1 was the most effective and significantly superior over all other treatments with more than 70.0 per cent reduction in whitefly population when compared to untreated control. The next best treatments were acetamiprid 20 SP @ 0.2 g L-1 (48.79 %) and thiacloprid 21.7 SC @ 0.25 ml L-1 (43.89 %). Thiamethoxam 25 WG @ 0.2 g L-1 (39.05 %) expressed better efficacy against whiteflies with more than 35.0 per cent reduction in whitefly population over untreated control. Thiamethoxam 25 WG @ 0.2 g L-1 and triazophos 40 EC @ 2.0 ml L-1 were on par with each other. Dimethoate 30 EC @ 2.0 ml L-1 (30.56 %) was found to be least effective with less than 35.0 per cent reduction in population over untreated control. Among the neonicotinoid insecticides, imidacloprid 200 SL was found to be less effective against whiteflies with less than 40 per cent reduction in population over untreated control. Development of resistance in whitefly population to imidacloprid, due to injudicious and indiscriminate use of imidacloprid 200 SL in different crops by the farmers may be the reason for the low level of suppression by the insecticide. However, in terms of whitefly suppression all the treatments were found significantly superior over untreated control.
