In vitro studies on the compatibility assessment of certain agrochemicals with microbial biopesticides used in tea [Camellia sinensis (L.) O. Kuntze] of Assam, Northeast India

In the present investigation, an attempt was made to assess the compatibility of seven biopesticides such as
Aspergillus niger (Identification code; MM/PSM/10), Azospirillum brasilense (Identification code; MM/AZM/
10), Bacillus subtilis (MTCC121), Beauveria bassiana (MTCC984), Trichoderma harzianum (IMI356100),
Trichoderma viride (IMI356099), Verticillium lecanii (MTCC956), isolated from the native tea ecosystem, against
twenty five agrochemicals using a novel approach. The results indicated the ability of A. niger and T. harzianum
to emulate in association with all the agrochemicals tested in vitro. The compatibility shown by some of the
biopesticides against the agrochemicals suggests their selective substantiation to cope with the integration of
chemical supplements
