Biomed J Sci & Tech Res Introduction Chilli (Capsicum annuum L) is one of the most valuable cash crops of India. It is a common and widely cultivated spices crop almost all over the world. Chilli is a richest source of vitamin C and A Howard [1].The chilly fruits are small in size and known for their sharp acidic flavor and colour. At present, chilly is produced in India about 1260.1thousands metric ton from an area of 792.1 thousands hectare, Anonymous [2]. Andhra Pradesh is the largest producing state of chilly. Indian chillies are mostly exported to Sri Lanka, USA, Nepal, Mexico, Malaysia and Bangladesh. Chilli suffers from a large number of viral, fungal, bacterial, nematode and phytoplasma diseases. Viruses is known to cause different symptoms like mosaic, ring spot, curling, yellowing etc. on chilly and these symptoms result heavy economic losses of about 15billion US Dollar per annum worldwide Van Fanbing [3]. Among them, chilly leaf curl is very common and affected to entire plants in the field with variable symptoms. It has been observed to cause high disease incidence with showing the symptoms of leaf curling, puckering and reduced size of leaves, closely set internodes and dwarfing of plants. These symptoms produce witch broom appearance and causes to failure of fruits setting. The fruit sets usually small and deformed. However, there are no published reports on the distribution of leaf curl viral diseases in major chilly growing areas of eastern Uttar Pradesh viz; Faizabad and sultanpur districts although, it is important disease of chilly crop. Materials and Methods The design adopted for the survey was stratified multistage sampling in two districts namely Faizabad and Sultanpur. The districts were classified into three blocks based on number of village surveyed. The survey was confined to five village of each block and villages were selected at random. These survey villages were visited for two consecutive years 2014 and 2015 from planting stage to harvesting stage i.e. 3 rd week of March, April and May. Data on the total number of plants, number of virus infected plants in per square meter. The days after disease appearance and visual disease incidence scoring method was adopted 0-9 point scale, Percentage of disease incidence was obtained by standard methods Joshi and Chaudhry [4] Other viral disease symptoms on chilly plant in the surveyed area were seen and collected separately for further confirmation through visual observation with consultation of standard literature McRae et al. [5-7] Per cent disease incidence was calculated given by Joshi and Chaudhry (1981) [4] as under: Number of infected plants per plots Disease incidence (%) x 100 Number of plants (diseased healthy) per plots = + Results and Discussion Field survey were conducted from 2014 and 2015 in 30 villages and total 150 fields in major chilly growing area of Faizabad and Sultanpur districts of eastern Uttar Pradesh. The results of survey revealed that most of the fields were found more than one viral infected symptoms. The virus infected leaf sample were collected Cite this article: AN Chaubey, RS Mishra. Survey of Chilli Leaf Curl Complex Disease in Eastern Part of Uttar Pradesh. Biomed J Sci & Tech Res 1(7)-2017. BJSTR. MS.ID.000589. DOI : 10.26717/BJSTR.2017.01.000589 Abstract Chili (Capsicum annuum L.) is an economically important and widely cultivated crop of India. Chilli leaf curl virus is one of the major limiting factors in chili production, which decreases yield significantly. The experiment was carried out in one hundred fifty villages randomly selected in eastern Uttar Pradesh viz, Sultanpur and Faizabad districts during 2014 and 2015 from March to May each year. The highest leaf curl incidence was noticed in Sewra (67.39 %) followed by Hasuimukundpur (65.22%) and Etwara (64.07%) in 2014, whereas in 2015, it was found maximum in Sewra (61.44%), Hasuimukundpur (59.79%) and Isawli (57.07%). In case of block wise, the maximum incidence was found Amaniganj (59.53, 50.79%) and Kurwar (54.70, 52.91%) in 2014 and 2015 respectively. While the lowest incidence was observed at Milkipur 47.46 % in 2014 and 41.48% in 2015 the average leaf curl disease incidence was recorded highest in 2014 at both districts.
