JAMMU, Aug 27: The Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu (SKUAST-Jammu) has issued a pest alert in response to a recent sporadic outbreak of Rice Hispa (Dicladispa armigera) in select areas of Jammu District.
The alert comes following observed damage in scattered rice fields, posing a potential threat to the rice crop.
Reports confirm Rice Hispa outbreaks in limited locations, including Mandal, RS Pura, and Bishnah blocks, as identified by scientists from SKUAST-Jammu.
Collaborating closely with the Department of Agriculture and supported by Agricultural Extension Officers, SKUAST-Jammu swiftly responded to observed damage at the research farm in Chatha, under the guidance of Prof RK Samnotra, Director Research.
The team, including experts like Dr Rajan Salalia and Dr Vijay Bahadur Singh, conducted an in-depth survey to assess damage extent and conducted adhoc recommendations.
Survey findings revealed concerning damage levels by this sporadic pest, particularly affecting the vegetative phase of rice plants. Damage ranges from 10% to 80% across surveyed fields, with indicators of infestation including leaf tip whitening, desiccation of young leaves, and blistering due to larval penetration.
To address the issue, the expert team suggested using chlorpyriphos 20EC (0.05%) at 1250 ml/ha upon manifestation of damage or insect presence, followed by a second round of spraying 40 days later.
Clipping and destroying the top three-fourths of leaves of highly infested crops at the early vegetative stage can also help suppress populations.
The potential escalation of this minor pest is compounded by climate change factors favoring its multiplication.
The pest alert highlights the critical need for vigilance in monitoring and timely intervention to counter its impact.
