(After George F. Atkinson.) CROPS SUGGESTED FOR INFESTED AREAS. Probably the best means of combating the nematock^ is b}- plant- ing crops which are not subject to its attacks. Such crops as corn, sorghum, wheat, rye, oats, and barlo}^ are among the most promising for this purpose. Corn and sorghum are particularly desirable, be- cause they permit clean tillage, and thus all weeds and other plants on which the nematodes might live may be kept out. It should be particularly noted that the sugar beet is susceptible to the nematode and should not be ])lanted on fields known to be infested. fCir. !)n.
