| Pest alert issued by SKUAST-Jammu for rice hispa outbreak | | | Early Times Report
JAMMU, Aug 27: The Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu (SKUAST-Jammu) has issued a Pest Alert due to a recent sporadic outbreak of Rice Hispa (Dicladispa armigera) in certain locations within the Jammu District. This alert has been issued in response to significant damage observed in scattered rice fields, posing a potential threat to the rice crop.
SKUAST-Jammu scientists have confirmed outbreaks of Rice Hispa in limited areas, including Mandal, R. S. Pura, and Bishnah blocks. This information was gathered through a pest survey conducted in collaboration with the Department of Agriculture, with support from Agricultural Extension Officers (AEOs) and other relevant personnel.
In response to the observed damage at the Research Farm in Chatha, SKUAST-Jammu took immediate action under the guidance of Prof. R. K. Samnotra, Director of Research. A team of experts conducted an in-depth survey to assess the extent of damage caused by the infestation.
The survey findings reveal significant damage caused by the sporadic pest, affecting the vegetative phase of rice plants in the affected locations. Damage levels range from 10% to 80% across different blocks and the Research Farm. Symptoms of infestation include whitening of leaf tips, desiccation of young leaves, and blisters near leaf tips due to larval penetration.
As interim recommendations, the expert team suggests applying chlorpyriphos 20EC (0.05%) at a rate of 1250 ml/ha when damage is observed or insects are detected. A second round of spraying is advised 40 days after the initial application, using chlorpyriphos (0.05%) or suitable alternatives like Neemazal (0.3%) or Econeem (0.5%). Additionally, clipping and removing the top three-fourths of leaves from highly infested crops with eggs and grubs during the early vegetative stage can help suppress pest populations. |
