Biochemical and quality parameters of BTRI released tea clones
The quantity of antioxidant, flavanols, flavonoids, polyphenols, and catechins biochemical compounds varies among the clones and varieties. Biochemical parameters of green leaves and made tea were analyzed with standard methods using UV-visible spectrophotometer.
Comparative studies on the performances of some plant cakes and synthetic chemicals against nematodes in tea in Bangladesh
A comparative study was undertaken to evaluate the performances of plant cakes and synthetic chemicals against nematodes infesting tea at Bangladesh Tea Research Institute (BTRI) during March 2012 to June 2012.
Determination of residue level of endosulfan in black tea in Bangladesh
The study was conducted at Bangladesh Tea Research Institute (BTRI), Srimangal, Moulvibazar, Bangladesh during 2007-08 in both dry and wet season on the mature tea to determine the residue level of Endosulfan (Thiodan 35EC) in black tea at different plucking intervals after spraying and their degradation rate in order to fix the plucking interval to keep the residue level at Maximum Residue Limit (MRL) or below.
Determination of residues of two organophosphates and their dissipation pattern by QuEChERS method
An experiment was carried out at the main farm of Bangladesh Tea Research Institute (BTRI) to find the residue levels of commonly used two organophosphate insecticides, namely chlorpyrifos and quinalphos in green leaf and black tea, at various plucking intervals after spraying during 2017-2018.
Development of integrated pest management strategy for tea mosquito bug (Helopeltis theivora Waterhouse) in Bangladesh
Tea is a perennial crop and grown as a monoculture on large contiguous areas. Tea plant is subjected to the
attack of several pests such as insects, mites and nematodes. Tea mosquito bug (Helopeltis theivora W.) is
one of the serious insect pests of tea in Bangladesh.
