Damping-off and stem rot disease-causing Sclerotium rolfsii has been reported as a destructive soil-borne pathogen of numerous crops, especially in the tropics and subtropics. Trials were conducted to test the efficacy of biocontrol agents alone or combined with Moringa oleifera leaf extracts for...

The biology of Sitophilus zeamais Motschulsky, an important pest of stored commodities, is well described in the literature. To integrate current knowledge and to understand better the population dynamics of this species in rural maize, Zea mays L., stores, we developed a distributed-delay, demog...

Striga gesnerioides is considered a major constraint to improving cowpea productivity in the semi arid region of Africa. A field survey was conducted in a farmer participatory process in 100 cowpea fields to determine farmers’ crop production practices that influence infestation by the parasitic ...

An expt. was established in Esparza (Costa Rica), on the integrated management of web blight (Thanatephorus cucumeris) in common beans under the min. tillage system. Var. Porrillo 70 (intermediate resistance) and ICA Pijao (susceptible) were used. Herbicides gliphosate and paraquat (1.0 kg/ha) of...

Root rot severely constrains bean (Phaseolus vulgaris L.) production in parts of Western Kenya. Genetic and soil management options were evaluated for an integrated root rot management approach. Four hundred genotypes were progressively screened in the field for resistance to root not over six se...

Cocoa-producing countries of West and Central Africa experienced a serious economic crisis in the early 1980s, when the cocoa sector was liberalized and the macroeconomic policies of the sector changed. These institutional changes created new difficulties and challenges for sustainable cocoa farm...

Au Mali, la production annuelle de mangues est estimée à 100 000 t. Du fait de problèmes structurels et phytosanitaires principalement liés à l'action des mouches des fruits, rarement plus de 1 % de cette production est exporté. L'objectif principal de cette étude a été de mettre au point une lut...
