Evaluation of some fungicides and antibiotics against fungal and bacterial pathogens of betelvine (Piper betleL.)

Abstract

Five fungicides, 2 antibiotics and 2 combinations of fungicides and antibiotics were evaluated against incidence of bacterial and fungal diseases of Piper betle L. Cv. 'Desawari'. Copper oxychloride 50 WP (Blitox-50) at 0.25% at 15 days interval was most effective against mortality caused by Phytophthora parasitica var. piperina Dastur; whereas 0.25% Copper oxychloride 50 WP with 500 ppm streptocycline was best against leaf spots caused by Xanthomonas campestris pv. betlicola Dye. and Colletotrichum capsici Syd. (Butler & Bisby). Other formulations viz., Carbendazim (Bavistin), Trideomorph (Calixin), Mancozeb (Dithane-M-45), Copper oxychloride 50 WP (Kilex), Paushamycin and Streptocycline were only next to the copper oxychloride 50 WP (Blitox-50) or its combination with streptocycline.

Assessment of Morphological Diversity and Vegetative Growth Parameters of Fifteen Betel Vine Varieties Cultivated Along the Odisha Coast

“…In certain areas, identical betel plants are grown under various names, while in other regions, distinct betel plants share identical names. As a result, varieties carry the prefix 'Desi' in their names [8]. Hence, it is consistently challenging to distinguish between varieties, often labelled with local names by the farmers.…”

DART MS Based Chemical Profiling for Therapeutic Potential of Piper Betle Landraces

“…No extensive systematic studies on characterizing these landraces have been made in the past. Some work on the essential oil has shown that most of the PB landraces fall into five broad groups, Bangla, Kapoori, Khasi, Sanchi and Meetha [4]. Studies conducted on molecular taxonomy using random amplified polymorphic DNA (RAPD) using seventy landraces have also shown the existence of major groups as Bangla, Kapoori and others [5,6].…”

“…The chemical constituents of betel essential oil consist mainly of terpenes and phenols [4], and the characteristic flavor of betel is due to phenols. The terpenoids include 1,8-cineole,cadinene, camphene, caryophyllene, limonene, and pinene.…”
