First Report Of Hog-Plum (Spondias Pinnata) Leaf Spot Disease, Kunal Mandal Dec 2011

First Report Of Hog-Plum (Spondias Pinnata) Leaf Spot Disease, Kunal Mandal

Kunal Mandal

Hog–plum is a tree species with edible fruits. The plant is naturally distributed in the tropical areas of the Indian subcontinent. Our effort to introduce it in the semi– arid conditions of western India failed as the plants developed severe shot–hole type leaf spot symptoms. Association of a fungus with the disease was detected and its pathogenicity was established. The pathogen was identified to the genus level (Colletotrichum) based on the morphological and molecular markers.


First Report Of Sweet Wormwood Leaf Blight Disease In India, Kunal Mandal Jan 2009

Artemisia annua is an important drug plant yielding antimalarial compounds. It was found to be infected by Alternaria alternata in India. The pathogen reduces active leaf area and is also known to produce mycotoxins. Hence, the disease demands serious attention to ensure the availability of a safe drug.


First Report Of Downy Mildew On Lepidium Sativum In India, Kunal Mandal Jan 2008

First Report Of Downy Mildew On Lepidium Sativum In India, Kunal Mandal

Kunal Mandal

Downy mildew caused by Hyaloperonospora parasitica on different members of Brassicaceae has been reported from different parts of the world. In India, the pathogen is recorded for the first time on Lepidium sativum. Proper management strategies need to be formulated against this disease as incidence is increasing.


Effect Of Different Levels Of N, P And K On Downy Mildew (Peronospora Plantaginis) And Seed Yield Of Isabgol (Plantago Ovata), Kunal Mandal, R. Saravanan, S. Maiti Jan 2008

Effect Of Different Levels Of N, P And K On Downy Mildew (Peronospora Plantaginis) And Seed Yield Of Isabgol (Plantago Ovata), Kunal Mandal, R. Saravanan, S. Maiti

The study showed that application of different doses of inorganic nutrients had considerable influence on growth, yield and downy mildew interaction in isabgol (Plantago ovata). It included three levels of nitrogen (0, 30, 60 kg N ha–1), two levels of phosphorous (0, 30 kg P ha–1) and two levels of potash (0, 40 kg K ha–1) for 2 consecutive years. The highest N supply (60 kg ha–1) caused more than 65% increase in disease severity compared with the control. However, application of 40 kg K ha–1 reduced percent disease index (PDI) by more than 10% compared with 0 kg K …
