Residue dynamics and effects of different household processes in reduction of fenpropathrin residues in chilli (Capsicum Annuum L.)
Spraying of chilli crop with fenpropathrin @ 75 and 150 g a.i./ ha led to the initial residues ranging from 0.12 to 0.14 and 0.19 to 0.22 mg/kg, respectively. Fenpropathrin residues in chilli dissipated below the limit of quantification after 3 and 5 days at low and high doses. The half-life of fenpropathrin in chilli was calculated to be 2.41 and 1.92 days. Residues of fenpropathrin on chilli collected 0 day after spray was below MRL following application @ 75 g a.i./ ha. Among various household processing methods, KMnO4 solution reduces 72.50 per cent residue washing, boiling, dipping in sodium bicarbonate solution, salt solution and acetic acid solution, respectively after 0 (2 hrs after spray) day of fenpropathrin @ 75 g a.i./ ha after third spraying in chilli.

期刊介绍:
Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments.
Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December.
Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
