Twelve cassava (Manihot esculenta Crantz) genotypes were planted under natural field conditions for two different cropping seasons (wet and dry), in 1992 and 1993 at the research farm of the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria. The trial studied the effect of p...

Effect of planting season on cassava anthracnose disease development
Cassava anthracnose disease (CAD) caused by the fungus Colletotrichum gloeosporioides f.sp. manihotis has become one of the major economic diseases of cassava in Africa. The expansion of cassava production farmlands particularly in the humid rainfall zones of West and Central Africa has led to an...

Anthracnose: an economic disease of cassava in Africa
This study was conducted to investigate a cheap and readily available alternative control measure for cassava anthracnose disease causal agent (Colletotrichum gloeosporioides f. sp. manihotis), through the use of antimicrobial crude plant extracts such as neem (Azadirachta indica), bitter leaf (V...

Fifty-three cassava lines were selected from breeding populations at the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria and screened in vitro for resistance to cassava anthracnose disease (CAD). The in vitro inoculation of stem cuttings with the fungus Colletotrichum gloe...

In vitro, greenhouse, and field assessment of cassava lines for resistance to anthracnose disease caused by colletotrichum gloeosporiodes f. sp. Manihotis
An in vitro method for assessing cassava anthracnose disease (CAD) resistance was developed as a preliminary screen to a CAD‐resistant breeding programme. Potato dextrose agar (PDA) media was amended by extracts from the stem cortex of 10 cassava cultivars (30001; 30572, 30211, 88/02549, 88/00695...
