Abstract

Compared with mono-cultures, beans grown in association with maize showed generally less incidence of the following diseases and pests: halo blight, bean common mosaic, anthracnose, common blight, scab,Phoma, mildew, bolworm and to a lesser extent angular leaf spot. For white mold and the black beetleSystates the opposite was observed. Rust and aphilds were erratic in this respect.

Apparently a kind of cultural control of the major bean diseases in Kenya is effected by growing beans in association with maize.

Samenvatting

Bonen in mengteelt met mais vertoonden over het algemeen in vergelijking met bonen in monocultuur minder aantasting door de navolgende ziekten en plagen: vetvlekkenziekte, bonerolmozaïek, vlekkenziekte, gewone vlekkenziekte, schurft, zwarte knopensiekte, meeldauw, peulenboorder en, in mindere mate, veelhoekvlekkenziekte. Het tegenovergestelde was het geval voor sclerotiënrot en de bladrandkeverSystates. Roest en de zwarte bonenluis gedroegen zich wat wisselvallig in dit opzicht. Geconstateerd mag worden, dat door mengteelt met mais een soort teeltkundige behersing van de belangrijkste ziekten en plagen in Kenya wordt bewerkstelligd.
