68 MISCELLANEOUS PAPERS. 



Remedies. — It is hoped that work now in progress in the Depart- 

 ment of Agriculture will result in the breeding of varieties of cotton, 

 peaches, etc., which will be resistant to root-knot. At present no 

 remedy is known that will entirely free land in our Southern States 

 from this disease. The sterilization of the soil by heat or toxic chem- 

 icals, clean fallowing, etc., have been recommended, but the best that 

 can be done in ordinary farm practice is to adopt a rotation designed 

 to starve out the parasites \>y growing a succession of immune crops, 

 such as the Iron cowpea, beggarweed, corn, oats, or other grains, 

 grasses, etc. A rotation like the following is suggested for cotton 

 planters: First year, corn, with Iron cowpeas between the rows; sec- 

 ond year, either beggarweed, velvet beans, or oats, followed by Iron 

 cowpeas; third year, cotton. If necessary cotton might also be planted 

 the fourth year, after which the rotation should be repeated.

REPORT RESULTS. 



It is desired to know the results of all trials of the Iron cowpea, and 

 every farmer who receives seed is requested to return the accompany- 

 ing card with his name and address, signifying his willingness to report 

 at the end of the season. Blanks will then be sent out to be filled and 

 returned. A report will be asked for on the character of soil, whether 

 or not infested with wilt or nematodes, manner of planting, character 

 of season, success as a forage crop, yield as compared with other varie- 

 ties, resistance to disease, etc.

[Circular sent to recipients of seed of Kleimvanzleben sugar beet.] 



KLEINWANZLEBEN STIGAK BEET. 



Grown by E. H. Morrison, at Fairfield, Wash., from mother beets 

 of exceptionall} r high sugar content and purity. The Department of 

 Agriculture wishes to have written reports as to the quality of this 

 seed, as sugar beet seed raising in the United States is a new industry. 

 All requests for either beet or vegetable seed for another year from 

 those sending such reports will be given special consideration.
