OTHER WEEDS. 



This list does not include by any means all of the injurious 

 weeds, but some of the worst. In some parts of the state some 

 weeds are more injurious than others. Quack grass is more im- 

 portant in northern Iowa than in southern. The horse nettle 

 is most troublesome in southern Iowa ; cocklebur is troublesome 

 in all parts of the state. The velvet weed, the smooth dock, 

 curly dock, and burdock are widely distributed. 



TREATMENT OP WEEDS. 



Weeds in order to be eradicated need various treatment. The 

 annual and biennial are not so difficult to exterminate as the per- 

 ennial. The first and most important consideration is clean cul- 

 tivation. In nearly every case this will destroy the annual weeds. 

 The land for corn should be plowed in the fall. The good farmer 

 will practice rotation of crops. If he uses the following rota- 

 tion : oats, clover and corn, the clover field can be plowed under 

 after the removal of the crop. The land will be reasonably clean, 

 because the cloevr is an excellent plant to keep many weeds down, 

 especially if the growth is rank. In the spring the field should be 

 disced, and the seedlings of many young plants will be destroyed. 

 The corn field should then be given clean cultivation. 



It is common practice in Iowa to sow oats directly on the corn 

 stubble, simply discing. This is bad practice. It would be far 

 better if the corn could be cut and the stalks used for fodder, 

 the field plowed in the fall and the oats sown in a clean field. 

 Usually the corn fields are so weedy in Iowa that it is difficult 

 to get a clean field of oats. The time is coming when the Iowa 

 farmer will cultivate his fields more thoroughly. 



Clover can be sown with oats, if the stand is even the ground 

 will be pretty well covered the next season. In Iowa clover is 

 usually treated as a biennial. This allows two years for a clover
