A first-of-its-kind field experiment laid out over 300 acres in 4 clusters of cotton field in Waroda and Adasa villages in Kalmeshwar Taluka in Nagpur District of Maharashtra
The South Asia Biotechnology Centre (SABC), Jodhpur in collaboration with Agrovision Foundation, Nagpur has laid out the country’s largest field experiment of an innovative mating disruption or mating confusion technology spread over 300 acres in 4 clusters to ward off Pest Pink bollworm (PBW) in cotton in Waroda and Adasa villages in Kalmeshwar Taluka in Nagpur District of Maharashtra.
PBKnot is an innovative mating disruption technology, approved recently by CIBRC of the Ministry of Agriculture & Farmers Welfares of the Govt of India is an ideal approach for effective PBW management and a best fit in IPM of bollworm management in cotton. Moreover, PBKnot technology is easy in application, safe to beneficial insects and eco-friendly.
A first-of-its-kind field experiment laid out over 300 acres in 4 clusters in GPS coordinated cotton fields with the structured tagging of PBKnot thread by trained local volunteers under the guidance of experts from South Asia Biotechnology Centre (SABC), Agrovision Foundation and ICAR-CICR will be studied for pest insect population dynamics, insect ecology and damage as part of an integrated pest management approach (IPM) of pink bollworm.
“We have laid out the country’s largest field experiment by tagging cotton plants with PBKnot in such a way that PBKnot charges the surrounding air with Gossyplure, a pheromone scent that confuses the male adults preventing them for finding and mating with female adults and reduces the number of eggs laid and PBW population in subsequent generations. Interestingly, PBKnot releases the same scent that female PBW releases to attract males for mating,” explained Dr CD Mayee, President of the SABC, Jodhpur.
“Mating confusion – a disruptive pheromone-based technique, is now available in the form of the solid metric dispenser rope known as PBKnot and can be easily applied to the cotton plant at the pin head square stage over the minimum area of 60 to 64 acres in contiguous basis. The PBKnot can protect cotton plant for 90 days in the crucial time of flowering, boll formation up to boll maturity and hence reduce boll damage, improve quality and increase cotton yield”, said Bhagirath Choudhary, Director of SABC, Jodhpur.
Project Bandhan is supported jointly by PI Foundation and Rasi Seeds Pvt Ltd and is being implemented across Vidarbha, Maharashtra, in partnership with cotton and textile value chain partners. The project aims at demonstrating mating disruption technology, promoting integrated pest management (IPM) based package of practices (POP) developed by ICAR-CICR, intensifying skill development and training programs and amplifying effective PBW control measures to farmers across the Vidarbha region. Project Bandhan enrolled hundreds of farmers in 4 clusters, were given free Bt cotton hybrid seeds & IPM based POP brochures and were engaged in tagging PBKnot thread dispenser in their field on 30th and 31st July 2021.
“Project Bandhan is an exemplary initiative toa promote pheromone based IPM production system of cotton. The novel PB Knot pheromone technology is easy to use, affordable and environmental friendly innovation to manage the devastating pest such as Pink Bollworm,” noted Mr. Prashant Hegde, CEO (Agri Business) at PI Industries Ltd.
“Rasi Seeds Pvt Ltd has been supporting the Pink Bollworm campaign in Vidarbha for the last two years, implemented jointly by the South Asia Biotechnology Centre and Agrovision Foundation. Our joint efforts have resulted in the management of Pink Bollworm, particularly in Vidarbha. We reinforce our commitment to support the innovative technology and programs to improve the cotton production and farmers’ realization. Project Bandhan is a unique program dedicated to showcase the utility, efficacy of novel mating disruption technology and IPM based production system,” stated Dr Ramasami, Chairman of Rasi Seeds Pvt Ltd.
“We have successfully implemented awareness and training programs on pink bollworm in collaboration with South Asia Biotechnology Centre across Vidarbha in the last 3-4 years. Implementing mating disruption technology will help growers to effectively manage pink bollworm in Vidarbha, Maharashtra while outreach program continues to spread right messages about IPM based management of pink bollworm,” stated Ravi Boratkar, President, Agrovision Foundation, Nagpur.
The implementation of PBKnot under the technical guidance of ICAR-Central Institute of Cotton Research (CICR) was attended by experts including Dr Rama Krishna, Agronomist and Dr Shailash Gawande, Plant Pathologist of ICAR-CICR, Ravi Boratkar, Ramesh Mankar, Rahul, Akash and Akshay of Agrovision Foundation; Dr Sandip Agale of South Asia Biotechnology Centre and elected representatives and hundreds of cotton farmers of Waroda and Adasa villages in Kalmeshwar Taluka in Nagpur District of Maharashtra.
