Opis

Current study was intended to verify the effectiveness of different fungicides alone and in combination against downy mildew of pumpkin. Diseased samples were collected for inoculation from different farms of Okara district. Selected chemotherapeutic mixtures were sprayed for the control of (Pseudoperonaspora cubensis) under field condition. After statistical analysis on recorded data Ipovalicarb (s) + Propanib (P) resulted in minimum disease incidence among all the treatments in the study by controlling the disease 60% as compare to Tebuconazole (s) + Metiram (p) was second effective treatment followed by Matlaxal (s) + Mancozeb (p) and the disease was controlled 58 and 55% respectively. Remaining three combinations Cymoxinal (s) + Mancozeb (p), Difenconazole (s) +Mancozeb (p) and Chlorothalonil (p) + Fosytyle Al (s) significantly control the disease incidence 52%, 46% and 39% respectively. Pumpkin crop showed comprehensible response to environmental correlation. Results exposed that optimum growth of (Pseudoperonospora cubensis) occur in moderate and rainy weather conditions with temperature range 25-28 ºC and rain fall measured about 0.5-0.7mm
