DAYS AFTER FUMIGATION 



Figure 2. The relationship of percentage of infection of tomato ('Bonnie 

 Best') (• •) and inoculum density of Fusarium oxysporum f. sp. radicis - 

 lycopersici (OwiiO) to time after fumigation of soils which were allowed 

 to recolonize naturally; the pathogen was added at 1000 chlamydo spores 

 per gram to 1500 g of soil every 7 days and tomato plants were maintained 

 in the infested soil for 14 days under growth- chamber conditions before 

 infection incidence and the inoculum density of the pathogen were 

 determined.
