Patent / Technologies / Methodologies / System etc. (Upto Five) :

  1. Succeessfully proved at molecular level, that low endogenous GA levels in buds infected with Fusarium mangiferae lead to development of mango malformation. Developed mango malformation disease prediction models using remote sensing and GIS tools.
  1. Single use plastic to laser induced graphene .Patent submitted. Identified fungi and bacteria that can degrade plastic
  1. Identified Sasri and Sasni as dwarf guava genotypes and selections from Alligarh and Black Guava (red flesh and soft seeded) R7T8, R6T7, R3T8, R5T9 (white flesh, soft seeded) as promising for north Indian conditions. Identified Bhaduaran, Ellaichi, H-8-11 (AxLS), H-2-6 (AxLS) as mango varieties resistant to mango malformation.
  1. Developed several bio formulations using 1) datura, calotropis and neem plant extracts; 2) Bacillus subtilis RP 24 ; and 7 Trichoderma strains for controlling mango malformation.
  1. Developed two organic pesticides that are promising against several sucking pests and fungi from 1) citrus and pomegranate fruit waste peels and 2) datura, calotropis, and neem plant extracts. Developed technology for converting Single-use plastic to Laser-induced graphene. Developed protocols for the degradation of plastic using solvents and fungi
