A two year field study was conducted at Agricultural Research station, Ragolu to study the efficacy of selected agrochemicals on the development of diseases (sheath rot, brown spot and grain discolouration) during reproductive phase in paddy. Treatments were imposed for two times, once at 50% panicle emergence and 15 days subsequently.

Rice plants require a particular temperature for its phonological affair such as panicle initiation; flowering, panicle exertions from flag leaf sheath and maturity and these are very much influenced by the planting dates during India season. Rice seeded before the window of optimum dates usually has slow germination and emergence, poor stand establishment and increased damages from soil borne seedling diseases.

A survey was conducted during Kharif 2016-2017 to assess the incidence of sheath blight disease in nine districts of Telangana state. The per cent disease incidence (PDI) ranged from 20 to 80 per cent. Maximum PDI (80) was recorded at Miryalaguda block, while minimum (20) was observed at Buddipally, Rudrur, Vangapally and Wyra villages. The maximum severity (9scale) was observed at Huzurnagar and Miryalaguda blocks. The disease was observed from panicle initiation to grain hardening stage.

Rice (Oryza sativa L.) is a staple food crop worldwide. Its yield and quality are affected by its tillering pattern and spikelet development. Although many genes involved in the vegetative and reproductive development of rice have been characterized in previous studies, the genetic mechanisms that control axillary tillering, spikelet development, and panicle exsertion remain incompletely understood.

Rhizoctonia solani causing sheath blight of rice is reported to survive through soil and collateral hosts. Although it infects seed in field, role of seed-borne inoculum in disease development is not properly understood. However, only little information is available on the role of seed-borne inoculum in disease development in the field (Roy, 1989; Acharya and Gupta, 1996; Silvalingam et al., 2006). During the present investigation seed samples of two varieties were collected from healthy seeds (i.e. seeds harvested from healthy plant panicles) and diseased seeds (i.e.
