Le résumé fourni par la source

Aim: The mango stem borer, Batocera rufomaculata De Geer has been observed to cause an alarming in old and young orchards. ICAR-IIHR, Bengaluru has developed a formulation called “Arka Borer Control” (ABC) for effective management of stem borers. The present study aimed to test the efficacy of ABC product against B. rufomaculata. Methodology: The ABC formulation (T1) was tested among 17 centers across the country through All India Coordinated Research Project on Fruits (AICRP-F) with other three treatments viz., pasting trunk with Bordeaux paste (BP) @ 10% + chlorpyriphos 20 % EC @ 10 ml l-1 of BP (T2), recommended/existing practice of the region (T3) and untreated control (T4) in RBD design with five replications during 2021 and 2022. Persistency of ABC product applied was also noted as supplementary observation. Results: The application of ABC minimized the stem borer infestation (79.75 % reduction over control) with lower number of live borer hole (76.00 % reduction over control) at Gangian, Lembuchera, Ludhiana, Medziphema, Rahuri, Rewa, Sabour, Sangareddy and Udaipur centres. The product also persisted for a longer period of time. Interpretation: In the present era of organic farming, ABC can be applied as a prophylactic measures on mango tree trunk up to height of 2.5 to 3.0 ft from ground level before the onset of rain for management of stem borer. Key words: Arka Borer Control, Bordeaux paste, Live borer hole, Mango stem borer
