NATURE OF RESISTANCE OF SWEETPOTATO TO SWEETPOTATO VIRUS DISEASE

Acta Horticulturae, 2002
Sweetpotato virus disease (SPVD) is a disease syndrome due to the dual infection and synergistic interaction of sweetpotato chlorotic stunt crinivirus (SPCSV) and sweetpotato feathery mottle potyvirus (SPFMV). SPVD causes up to 98% yield loss in East Africa.

Resistance in Sweetpotato to Sweetpotato Weevil

International Journal of Tropical Insect Science, 1987
Sweetpotato weevil, Cylas formicarius formicarius F is the most destructive pest of sweetpotato, Ipomoea batatas in tropical and subtropical regions. The larvae and adults feed on sweetpotato roots and crowns. For the past 12 years we have been screening sweetpotato germplasm for resistance to this pest in order to breed an agronomic cultivar with ...

SWEETPOTATO LEAF CURL VIRUS AND RELATED GEMINIVIRUSES IN SWEETPOTATO

Acta Horticulturae, 2002
Sweetpotato leaf curl diseases have been reported in Taiwan, Japan, and the United States. The causal agent is the whitefly transmitted geminivirus, Sweetpotato leaf curl virus (SPLCV). Viral DNA can be detected in plant samples using polymerase chain reaction (PCR) with SPLCV-specific primers.

Viruses in Sweetpotato

2012
Sweetpotato in the Mediterranean is mainly grown in Egypt, Spain, Portugal, and Israel. Yields vary from 34 tons/ha in Israel to 7.8 tons/ha in Portugal. As sweetpotatoes are vegetatively propagated, the differences in yields are probably due to the quality in the propagation material, mainly infection by various viruses.

Fumigation of Sweetpotatoes with Methyl Bromide for Control of the Sweetpotato Weevil

Journal of Economic Entomology, 1940
The sweetpotato weevil (Cylas formicarius (F.)) is at present found in Texas, Louisiana, Mississippi, Alabama, Florida, and Georgia. It attacks the vines and roots of the sweetpotato, making the roots unfit for human consumption. The entire egg, larval, and pupal stages and part of the adult stage are spent within the vines or roots.
