Efficient screening procedure for black sigatoka disease of banana

African Crop Science Journal, 2015
Current methods for screening for reaction of Mycosphaerella fijiensis are mostly field based and subject to variability caused by weather conditions. The objective of this study was to develop an efficient screening procedure for black sigatoka disease in order to provide a reliable controlled environment screening method.

Genetic Improvement for Resistance to Black Sigatoka in Bananas: A Systematic Review. [PDF]

Front Plant Sci, 2021
Bananas are an important staple food crop in tropical and subtropical regions in Asia, sub-Saharan Africa, and Central and South America. The plant is affected by numerous diseases, with the fungal leaf disease black Sigatoka, caused by Mycosphaerella fijiensis Morelet [anamorph: Pseudocercospora fijiensis (Morelet) Deighton], considered one of the ...

Management of black sigatoka in Cameroon [PDF]

, 2006
In Cameroon, Mycosphaerella fijiensis was reported for the first time in 1981 and the control against black leaf streak disease represents the highest production cost which can attend up to 10% of total production cost. In fact, the epidemiological context which exists in Cameroon is particularly favourable to the disease notably in the rainy season ...

Silicon Reduces Black Sigatoka Development in Banana [PDF]

Plant Disease, 2012
The effect of silicon (Si) uptake on the susceptibility of Musa acuminata to Mycosphaerella fijiensis was investigated in three experiments conducted under controlled conditions. Plants were grown in the presence of Si or not, in pots adapted for a hydroponic culture system or in pots filled with compost. The banana leaves were inoculated after 4 or 6

Black Sigatoka Classification Using Convolutional Neural Networks [PDF]

International Journal of Machine Learning and Computing, 2021
In this paper we present a methodology for the automatic recognition of black Sigatoka in commercial banana crops. This method uses a LeNet convolutional neural network to detect the progress of infection by the disease in different regions of a leaf image; using this information, we trained a decision tree in order to classify the level of infection ...

Variable number of tandem repeat markers in the genome sequence of Mycosphaerella fijiensis, the causal agent of black leaf streak disease of banana (Musa spp) [PDF]

, 2010
. We searched the genome of Mycosphaerella fijiensis for molecular markers that would allow population genetics analysis of this plant pathogen. M. fijiensis, the causal agent of banana leaf streak disease, also known as black Sigatoka, is the most ...

First Report of Black Sigatoka in Florida

Plant Disease, 1999
Black Sigatoka, caused by Mycosphaerella fijiensis, is widely recognized as the most important disease of banana, Musa spp. It has spread rapidly in the Western Hemisphere since it first appeared in Honduras in 1972, and is now found in the Caribbean basin in Cuba, Jamaica, and the Dominican Republic, and on the mainland from central Mexico south to ...
