Pyramiding transgenes for multiple resistance in rice against bacterial blight, yellow stem borer and sheath blight

Theoretical and Applied Genetics, 2002
Here we describe the development of transgene-pyramided stable elite rice lines resistant to disease and insect pests by conventional crossing of two transgenic parental lines transformed independently with different genes. The Xa21 gene (resistance to bacterial blight), the Bt fusion gene (for insect resistance) and the chitinase gene (for tolerance ...

SCREENING FOR RESISTANCE TO BOTRYOSPHAERIA STEM BLIGHT AND PHOMOPSIS TWIG BLIGHT IN BLUEBERRY

Acta Horticulturae, 2006
Stem diseases of blueberry ( Vaccinium spp.) can cause significant crop loss as well as loss of entire bushes. Stem diseases also tend to be more difficult to control with fungicides than foliar or fruit diseases. We have initiated a program to screen blueberry cultivars for resistance to two important stem diseases, Botryosphaeria stem blight and ...

Fungi Associated with Leaf and Stem Blight of Vanilla

Journal of Agricultural Research and Development, 2009
The study was carried out to isolate and identify fungi associated with leaf and stem blight of vanilla. The pathogens were isolated from the symptoms expressed on leaves and stem by direct tissue transplanting technique. Result showed that leaf blight was mainly associated with Colletotrichum gloeosporioides, Phytophthora sp., Curvularia lunata, and ...

OBSERVATIONS ON STEM CANKER AND POD AND STEM BLIGHT OF SOYBEANS IN ONTARIO

Canadian Journal of Botany, 1956
Stem canker caused by Diaporthe phaseolorum (Cke. & Ell.) Sacc. var. caulivora Athow & Caldwell is a serious disease of soybeans in Ontario. Artificial inoculation experiments have indicated (a) that soybeans which are highly susceptible to infection at midstage in their development become progressively less so as they approach maturity, (b ...

Chemical management of Volutella leaf and stem blight of boxwood

European Journal of Plant Pathology, 2015
Volutella blight of boxwood, caused by the fungus Pseudonectria buxi, can cause extensive losses in commercial nurseries. To assess chemical methods for management, several fungicides commonly used to control diseases on ornamental plants were used in inhibition tests of fungal growth on amended media and on whole plants.

The emergence of gummy stem blight: A threat to cucurbits in India

Agrica, 2017
Cucurbits production is significantly affected by gummy stem blight caused by fungus Didymella bryoniae across the globe. In India, vine decline has emerged as a serious problem in cucurbits. The fungi survive on seeds, weeds, volunteer cucurbits, and plant debris from previously infected cucurbits. Detection techniques based on PCR DB-F3/DB-R3, GSBF1/
