摘要

The potato (Solarium tuberosum L.) is grown in many parts of North-central and Northwestern parts of India under wide range of agro climatic conditions as an early cash crop fetching 70-80% higher remunerative price in the market (Bhatnagar et al, 2011). However, the production of this crop is hampered by various biotic and abiotic factors. The most important among them is thrips, Thrips palmi Kerny (Bhatnagar, 2007a) and transmitting important groundnut bud necrosis virus (GBNV), resulting in stem necrosis disease in early potato. This disease has assumed significant status especially in parts of Madhya Pradesh, Rajesthan and Gujrat a decade earlier (Khurana et al, 2001). Thrips a cosmopolitan and important insect which attack weeds, flower, treesand large number of field and vegetable crops (Ananthakrishan, 1980; Kawari, 1986). Thrips can cause 20-60% damage to early potato crop depending upon climatic conditions. With the increasing temperature due to global climate change, the incidence of thrips is expected to increase in central India (Bhatnagar et al, 2014). The yield loss by thrips is mainly due to transmission of stem necrosis disease (Bhatnagar, 2007b,Bhatnagar and Thakur, 2008, Ullman et al, 1997). Temperature and humidity plays an important role for multiplication of vector population and subsequent development of disease in early potato due to transmission of GBNV (Bhatnagar, 2011, Bhatnagar et al,2011). The repeated use of insecticides is increase the cost of cultivation and also increase environmental pollution hazard on non-target organisms. The problem is further aggravated due to the development of resistance against conventional insecticides being used by the farmers (Bhatnagar, 2013). Therefore, in view of this problem, efforts were made to evaluate early planting dates of potato with relation to weather factors, thrips population and incidence of stem necrosis disease.
