Burns and Wilts. 



For Lettuce Top Burn, maintain low temperature during damp, 

 cloudy weather. For cucumber wilt and burning of leaf edges, avoid 

 excessive use of nitrate and secure good texture of the foliage by 

 means of sufficient li^rht and ventilation. 



GENERAL OUTLINE OF TREATMENT. 



Apple. First treatment before buds swell, formula la or 2. Sec- 

 ond treatment just before blossoms open, ib or 20 or 21. After the 

 blossoms fall treat again with 20 or 21. If the weather is wet and 

 scab fungus is severe, treat at intervals of two weeks with ib. For 

 canker worm and curculio treat just before the blossoms open with 

 20 or 21, as recommended above. For scale use 15. 



Apricot. Same as for peach or plum, which see. 



Asparagus (rust, summer stage). Spraying thoroughly during 

 July and August a few times with ib or ig constitutes a partial 

 preventive. In planting new beds avoid too dry soil. For aspar- 

 agus beetle, spray summer growth with Xo. 10. 



Bean. When third leaf expands use ib for rust or anthracnose, 

 followed ID days later by a second application of the same. Repeat 

 later as necessary. 



Blackberry. Use ib or 2 before buds open. Just before the 

 blossoms open use 30, 21 or 22. Repeat every ten days or two 

 weeks if required. 



Cabbage. Lime at the rate of 35 to 50 bushels an acre is recom- 

 mended for club root, but is not always successful. 



Celery. For rust and blight, spray seed beds with ib every two 

 weeks. The same solution may be sprayed on the plants after set- 

 ting out, at intervals of two weeks. 



Cherry. Treatment practically the same as for plufii, \Thich see. 

 Currant. Use ib before leaves start. At tirst appearance of 

 worms use iS, and as often afterward as the worms reappear.
