In a study on the influence of varieties, spacings and pest management, spraying with monocrotophos 36 WSC at 500 ml/ha. recorded significantly lower infestation of pests and an increase of 10% grain yield. insect resistant cultures IET 6315 and ACM 8 recorded significantly lower incidence of gall midge and stem borer as compared to IR 20. Spacings had no influence on the incidence of the pests and yield. IR 20 at a spacing of 20 x 15 cm, sprayed at ETL recoided the lowest incidence of leaf folder. IET 6315 and ACM 8 recorded significantly lower damage in 20 x 15 cm spacing. The results suggest that gall midge incidence in the moderately resistant varieties can be reduced by adopting a wider spacing and on susceptible varieties with insecticides.
Pleomorphic adenoma (PA) is the most common benign tumor of major salivary glands and intra nasal PA is unusual which may be misdiagnosed as malignancy. A 65-year-old female presented with unilateral nasal bleeding and nasal obstruction in right nasal cavity for 6 months. Local examination showed polypoid mass which surgically excised. HPE showed classic triphasic component of epithelial, myoepithelial with cartilaginous stromal elements and pathological diagnosis of PA made. High cellularity of tumor and predominant squamous epithelial component with keratin pearl created diagnostic confusion of malignancy and it confirmed by immune-histochemistry using p63 to demonstrate presence of myoepithelial component. Highlighted this case report for its unusual location and rare triphasic component of tumor tissue with keratin pearl formation which mimic as malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
