1 The figures of this state on peas were omitted in the oflGicial report of 1910 because they were not complete at that time. They 

 have since been compiled, and are as follows: 



1910—210,000 cases. 



1911—160,000 cases. 

 To prevent confusion or misunderstanding the figures of this state are given in this explanatory note. 



PEA DISEASES 



Anthracnose 



AscocJiyta pisi Lib. 



The anthracnose, or pod spot of the pea 

 often develops into a serious blight of 

 field peas grown for canneries. The 

 anthracnose fungus infects the seed peas 

 so that these when planted give diseased 

 seedlings and the consequent loss of crop. 



It has been shown that by spraying 

 with Bordeaux mixture healthy seed 

 peas may be grown. The growth of 

 healthy peas for seeding disposes of the 

 problem of anthracnose. See also an- 

 thracnose of beans. 



Blight 



Beptoria pisi West 



Produces black spots on the leaves and 

 pods and seriously injures the vine. Most 

 troublesome in wet weather. 



Spray with Bordeaux mixture if the 

 trouble is serious enough to make it 

 profitable. 



FusARiTJM. See Watermelon Diseases. 



Pod Spot. See BMgM. 



Leaf Spot 



Beptoria pisi West. 

 Other leaf spots besides those of the 

 anthracnose are sometimes found upon 



the pea and are apparently caused by 

 another fungus. These, if giving trouble, 

 will be controlled by the spraying for 

 anthracnose. 



Mildew 



Erysiphe polygoni. 



Covers the plants and pods with a 



white mildew. Most prevalent in wet 



weather and is usually only serious on 



the winter crop. 



Dust the vines with dry sulphur at the 

 first appearance of the trouble. 



In cloudy weather spraying with Bor- 

 deaux mixture is most effective. 



Powdery Milde^v 



ErysipJie communis Wallr. 



The mildew fungus often attacks the 

 pea and at times entirely destroys its 

 fruitfulness. It may be known by the 

 whitish coating produced upon the leaves 

 and by the dark, pin-head spots of the 

 fungus observed to be situated in these 

 white coverings. The same fungus like- 

 wise attacks the bean. For either plant 

 spraying with Bordeaux mixture will be 

 found beneficial. The first application 

 should be made promptly.
