| |Cultivation package for DRR-2 Hybrid
Directorate of Rice Research (DRR) has developed and released a second hybrid viz., DRRH-2. This is an early maturing hybrid (115-117 days). This hybrid has been released for the states of Tamil Nadu, West Bengal, Uttaranchal and Har
Manual transplanting involves a lot of human drudgery as the operation is done in bending posture for longer periods. It is essential that the timely transplanting is important to achieve good crop yields.
Delayed monsoon forces the farmer to go for planting in a short span of time for which the nursery availability becomes a serious constraint.
Direct seeding is the often-resor' 3d practice to circumvent these problems. The practice of seed broadcasting often results in
| |Pink stem borer (PSB), Sesamia inferens (Walker)
Distribution: This species has been reported from all over India but is more common in areas where rice is followed by wheat crop and also in upland rice regions.
| |Gold fringed borer (GFB), Chilo auricilius (Dudgeon)
Distribution: This is an important pest of sugarcane and rice. The distribution range of C. auricilius overlaps with that of its look-alike C. polychrysus. It is also found in West Bengal, Bihar, UP, Gujarat, Jammu & Kashmir.
| |Dark headed borer (DHB), Chilo poly chrysus(Meyrick)
Distribution: It has been reported from Kerala, Assam, West Bengal, Orissa and Tamil Nadu but it often assumes the status of major pest in Tamil Nadu and Kerala.
| |Striped stem borer (SSB), Chilo suppressalis (Walker)
Distribution: This borer species has been reported from plains of India, Assam, West Bengal, Bihar, Orissa and Kerala.
| | 1. White stem borer (WSB)

a. White rice borer, Scirpophaga nivella (Fabricius)
| |Yellow stem borer (YSB), Scirpophaga incertulas (Walker)
Distribution: This species is prevalent in many states across the country. It is a serious pest in all the rice ecosystems, particularly in deep water rices.
