Abstract
The addition of Endogone calospora to fumigated soil significantly increased shoot and root growth of citrus seedlings in the greenhouse but not in the field. The addition of E. macrocarpa significantly increased growth of transplants and seedlings in nonfumigated and in methyl bromide-, and dichloropropene-fumigated field soil. This beneficial effect did not occur in soils aerated by disking after fumigation. Within 100 days, endomycorrhizal fungi were reestablished on weed roots growing in fumigated soil. Citrus stunting was greater after methyl bromide fumigation than after dichloropropene fumigation, but seedling stunt was not as severe as that observed in some commercial nurseries. Thus our results may not be applicable to correcting citrus stunt as found in commercial nurseries
