(2009) GREEN-HOUSE AND FIELD ASSESSEMENT OF FUSARIUM OXYSPORUM BASED MYCOHERBICIDE FOR THE CONTROL OF STRIGA HERMONTHICA IN MAIZE (ZEA MAYS L.)https://keffi.nsuk.edu.ng/handle/20.500.14448/3071Green-house and field trials were conducted to evaluate the effectiveness of a granular -oherbicide.ftom Fusarium oxysporum in controlling Striga hermonthica in maize pot culture and under a field condition. In the field trial, among the tested maize varieties, the farmers’ local initiated early emergence of Striga by 36 days after sowing (DAS) while Across 97 TZL delayed by 49 DAS. Throughout the period of observation, the numbers of maize plants infected with Striga/ snoot count were significantly lower in all F. oxysporum- mycoherbicide treated plots when compared -م the highest obtained with hoe-weeded check. Similarly, in the pot experiment, number of emerged Striga was significantly lower in F. oxysporum treated pots when compared to the control. However, the control recorded higher Striga dry weight أ! treatments that received Fusarium. In the field trial, maize grain yield was significantly lower at Makurdi location than at Lafia. Similarly, the farmer’s local variety produced significantly lower grain yield than Across 97 TZL. The use of F. oxysporum followed by (fb) either post-emergence application (POE) 2, 4 - D or Triclopyr each at 36 لأkg a.i/ha resulted in significantly higher grain yield than those fb supplementary hoe weeding (SHW) or hoe weeded check. The study results demonstrate the potentiality of using F. oxysporum and thereafter either fb POE 2, 4 - D or Triclopyr at 6 weeks after sowing (WAS) for the control of hermonthica.enStriga, biocontrol, Fusarium oxysporum, mycoherbicide, maizeArticle
