Dark leaf and pod spot (Alternaria brassicae) on oilseeds (Brassica napus) in Lithuania

Fungicidal Activity of Aqueous Leaf Extract on Alternaria brassicae

Alternaria brassicae is a widespread pathogen causing black leaf spot in the common cabbage (Brassica oleracea Linn.). Ample spectrum of effective chemical fungicides is in use against this pathogen. The agricultural areas of the Nilgiris are fragmented shola forests of this biodiversity hot spot. The indiscriminate usage of chemical fungicides may cause physiological damage, including the endo...

Hormones and Pod Development in Oilseed Rape (Brassica napus).

The endogenous levels of several plant growth substances (indole acetic acid, IAA; abscisic acid, ABA; zeatin, Z; zeatin riboside, [9R]Z; isopentenyladenine, iP; and isopentenyladenosine, [9R]iP were measured during pod development of field grown oilseed Rape (Brassica napus L. var oleifera cv Bienvenu) with high performance liquid chromatography and immunoenzymic (enzyme-linked immunosorbent a...

Symptomological, Cultural and Molecular Variability of Alternaria Brassicicola Leaf Spot in Broccoli (brassica Oleracea Var. Italica L.)

Variation of Alternaria brassicicola leaf spot of Broccoli (Brassica oleracea var. italica L.) was evaluated based on morphological, cultural and molecular parameters during Rabi season 2010 and 2011. Six isolates of Alternaria were cultured in vitro using different growth medium and the growth pattern of the fungi was studied. Maximum 86 leaf spots were recorded from Naini followed by BHU (74)...

Analysis of leaf appearance , leaf death and phoma leaf spot , 1 caused by Leptosphaeria maculans , on oilseed rape ( Brassica 2 napus ) cultivars

Sulphur supply and infection with Pyrenopeziza brassicae influence L-cysteine desulphydrase activity in Brassica napus L.

Different field surveys have shown that sulphur (S) fertilization can increase the resistance of agricultural crops against fungal pathogens. The mechanisms of this sulphur-induced resistance (SIR) are, however, not yet known. Volatile S compounds are thought to play an important role because H(2)S is toxic to fungi. A field experiment was conducted to analyse the influence of S fertilization a...
