The experiment was conducted to compare effectiveness of (BtA) Bacillus thuringiensis and Abamectin @ 1gm/l with chlorpyrifos @ 5ml/l, megamos @ 1.25 ml/l and trend @ 4ml/l in controlling aphids (Lipaphis erysimi) on rapeseed (Brassica campestris) Agriculture Research Farm NWFP Agricultural University Peshawar. These compounds were first sprayed to the point of runoff when the density of the ap...

Background The family Brassicaceae comprises several important crops cultivated in Brazil, including broccoli, cauliflower and cabbage. One of the main diseases that affects all cruciferous plants is black rot, caused by the bacterium Xanthomonas campestris pv. campestris (Xcc). This bacterium causes serious damage to the plant, leading to severe yield losses. The disease control is extremely d...

Pollenopyrroside A and pollenopyrroside B, novel pyrrole ketohexoside derivatives, were isolated from the extract of Bee-collected Brassica campestris pollen. Their structures were elucidated by spectroscopic analysis (UV, IR, MS, NMR and X-ray) and chemical evidence. Pollenopyrrosides A and B represent a novel carbon skeleton with a six-six and five-six member dioxaspirocycle bearing nitrogen ...

An experiment was conducted at the farm of Zonal Adaptive Research Station, Uttar Banga Krishi Viswavidhyalaya, Pundibari, Cooch Behar, West Bengal to evaluate the effect of pendimethalin on the yield, weed density and phytotoxicity in different varieties of rai (Brassica juncea) and yellow sarson (B. campestris var. yellow sarson) under higher soil moisture regime in Terai region of West Benga...

Amount of polyphenols, flavonoids, anthocyanins in ethanol extracts and antioxidant activity of both ethanol and lipophilic extracts of common leafy vegetables in Bangladesh were compared. Among the 12 leafy vegetables, Ipomoea aquatica Forssk. showed the highest content of total polyphenols (38.9 mg gallic acid equivalent (GAE)/g extract) and flavonoids (23.2 mg (+)-catechin equivalent (CE)/g ...

Weed suppression is one of the several benefits achieved by soil incorporation of crop residues and such suppression is believed to be allelopathic in nature. The allelopathic potential of different crop residues: viz. sorghum (Sorghum bicolor [L.] Moench), sunflower (Helianthus annuus L.), brassica (Brassica campestris L.) was evaluated in rice (Oryza sativa L.) and jungle rice (Echinochloa co...
