Molecular characterization, vector identification and sources of phytoplasmas associated with brinjal little leaf disease in India
Brinjal little leaf (BLL) is a widespread disease of phytoplasma etiology in India that induces severe economic losses. Surveys were conducted in eight brinjal-growing states of India during July 2014 to September 2015 and eighteen BLL samples showing little leaf, phyllody and witches' broom symptoms were collected for phytoplasma identification. Presence of phytoplasmas was confirmed in all th...
متن کاملPERSISTENCE OF ABAMECTIN RESIDUES IN/ON BRINJAL (Solanum melongena)
Spray application of abamectin (CHA 2062) was given twice to brinjal crop at 15 days interval at the recommended dose and double the recommended dose of 14.4 and 28.8 g a.i./ha during December, 2007March, 2008 to study its residue persistence. Initial residues of abamectin on brinjal from the two treatments were 0.202 and 0.815 mg/ kg, respectively. The residues persisted for 3 days from both t...
متن کاملMolecular characterization of phytoplasma of 16SrI-B group association with Acalypha indica in India
The typical phytoplasma symptoms of little leaf, yellowing, chlorosis, witches' broom, and stunting growth were observed on Acalypha indica plants during the field survey conducted at Lucknow and surrounding districts in year 2015-2016. To confirm the association and possibility of phytoplasma etiology, PCR assays were performed using universal primer pairs (P1/P6) and nested primer pairs (R16F...
متن کامل‘Candidatus Phytoplasma cynodontis’ associated with white leaf disease of golden beard grass (Chrysopogon acicalatus)
A phytoplasma was detected in golden beard grass (Chrysopogon acicalatus) displaying white leaf symptoms near vegetative fields at the Tatkone region in Myanmar, 2011. Based on restriction fragment length polymorphism analysis of PCR-amplified 16S rRNA genes, including the 16S-23S spacer region and part of the 23S rRNA gene, the phytoplasma was identified as a member of the Bermuda grass white ...
متن کامل'Candidatus Phytoplasma brasiliense', a new phytoplasma taxon associated with hibiscus witches' broom disease.
Hibiscus rosa-sinensis is a valuable ornamental species widely planted in Brazil. Many plants are affected by witches' broom disease, which is characterized by excessive axillary branching, abnormally small leaves, and deformed flowers, symptoms that are characteristic of diseases attributed to phytoplasmas. A phytoplasma was detected in diseased Hibiscus by amplification of rRNA operon sequenc...
