Abstract:Abstract

Groundnut rust (Puccinia arachidis Speg.) is widely spread in Zambia and is a new threat to groundnut crops in Africa. Fungicides tested for Cercospora control were also effective when both rust and leafspot occurred and yield increases up to 102% were obtained. The most effective chemicals were chlorothalonil, mancozeb plus benomyl and a mixture of mancozeb, benomyl and fentin.
Keywords:Tomato fruit borer  Heliothis armigera (Hubner)  crop management practices  p.e.c.  endosulfan
