COTTON LEAF CURL DISEASE

High phenotypic coefficient of variation and genotypic coefficient of variation were observed for percent potato apical leaf-curl disease (PALCD) incidence at 40, 60 and 80 DAP, whitefly population at 20 and 30 DAE and phenols. High heritability (broad sense) along with genetic advance as per cent o[r]

This is because the incidence and spread of a single virus disease may be dependent on several vectors which have complicated ecologies themselves (Bos, 1986). Whitefly (Bamasia tabaci) transmitted cotton leaf curl virus disease was the major problem in cotton cultivation (Sharma et al., 2006). Howe[r]

Rice is an important food crop in India. One of the major constraints of rice production is that it is prone to several diseases. Among them brown leaf spot disease has been reported to occur in all rice growing regions. A study was conducted to determine the performance of fifty paddy varieties aga[r]

Turcicum leaf blight (TLB) or Northern Corn Leaf Blight (NCLB) is a ubiquitous foliar disease of corn (maize) caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria. The TLB fungus survives through the winter on infected maize residue at the soil surface. As temperatures rise in[r]

A field experiment was conducted to find out the effect of different intercrops on growth and yield attributes of American cotton under dryland condition during kharif season of 2014-15 at the farm of AICRP for Dryland Agriculture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra).

The present investigation entitled efficacy of Hexaconazole (Contaf) on Alternaria leaf spot of wheat was proposed with the objective to evaluate the efficacy of Hexaconazole (Contaf) treatments on disease intensity.

In the present investigation was carried out to find out the most effective fungicide for controlling the Cercospora leaf spot disease. Along with fungicides we had tried to find out the alternate methods for controlling the disease by evaluating the bio efficacy of certain bio fungicides.

Citrus Yellow Mosaic Virus (CYMV) disease and citrus greening bacterium are two important diseases in citrus. Citrus yellow mosaic virus (CYMV) disease is caused by bacilliform DNA virus while citrus greening disease caused by a fastidious bacterium (Candidatus liberibacter asiaticus) (Cla). Both th[r]

The bacterial leaf blight of rice caused by Xanthomonas oryazae pv. oryzae is the disease of great economics importance in India especially in Bihar. Management of BLB disease can play a vital role in management of rice disease. In the present investigation evolution of different plant extract (bota[r]
