The Rhizoctonia Disease of Tomatoes 



[State Agricultural Experiment Station, Pallman, Washingfton] 



THE disease of tomatoes known in 

 the Northwest under various names 

 as blight, yellows, yellow blight or 

 western blight, is due to the sterile 

 fungus, Rliizoctonia, which lives upon 

 the roots of the affected plants. Ac- 

 cording to the Pathologist of the Ex- 

 periment Station, the symptoms and 

 effects of the disease are as follows: 



1. The aerwl parts of the plant: 

 Dwarfing or reduction in size of the 

 entire plant; the production of the 

 rosette type of growth; discoloration of 

 the foliage; curling or rolling of the 

 leaflets; reduction in size of the fruit 

 and premature ripening or failure to 

 set any fruit; wilting and death of the 

 entire top. 



2. On the roots: A network of 

 brown fungous filaments upon the sur- 

 face of the roots; the occurence of 

 black nodules or masses (scleroti) at 

 various points upon the roots; the 

 presence of dead corroded areas 

 (lesions) upon the roots or basal por- 

 tion of the stem; the death of roots 

 from the tij) backward; an abnormal 

 production of adventitious fibrous roots. 



The parasite is present only on the 



roots or basal portion of tlie stem and 

 the symptoms shown by the foliage are 

 only an indirect effect of the parasite. 

 The disease may be barely evident or 

 sufFiciently severe to kill the atTected 

 plants. The same fungus causes the 

 "daraping-off" of seedlings. 



Control: The habits of the causal 

 fungus must be taken into considera- 

 tion in methods of control. Rhizoc- 

 tonia is common in many soils and 

 attacks many wild plants and cultivated 

 crops. It has been noted in Washington 

 during the past two years as the cause 

 of serious disease in potatoes, beans, 

 beets, peas, cucumbers, peppers and 

 strawberries. Infected seed potatoes 

 are undoubtedly responsible for many 

 cases of serious soil infection. 



Cultural practices must be resorted 

 to in the control of this disease and the 

 following suggestions are offered for 

 the guidance of growers: 



1. Use clean soil free from Rhizoc- 

 tonia for the growth of tomato plants 

 if they are to be transplanted, or if the 

 soil is infected use some method of 

 sterilization.

2. Avoid ground upon which pota- 

 toes have been grown during the past 

 four or five years. Give attention to 

 the possible occurrence of the disease 

 upon some other crop that might have 

 infected the soil. Cereals and other 

 grasses are never attacked by Fthizoc- 

 tonia. 



3. Practice a culture that will supply 

 the growing plants with an abundance 

 of moisture. Lack of moisture in-
