SOME MEANS FOR PREVENTING THE INTRODUCTION OF WEEDS AND A FEW RULES FOR THEIR EXTERMINATION.
1. The right kind of a man, who will carefully observe and study the kinds of weeds and their habits, fighting each to the best advantage, i. e. with method.
2. See that all seeds purchased or grown at home for seed are free from seeds of weeds. Although often heard, these words are too little heeded.
3. See that threshing machines, hay racks, grain bags from other farms are well cleaned before used on the farm.
4. Cook or grind screenings and burn chaff when certain weeds are suspected.
5. Send seeds to the Agricultural College, East Lansing, for identification, unless they are known to be harmless.
6. Strive to prevent weeds from ripening seeds. This is especially important late in the season in case of all pigweeds, purslane and others where the flowers are very small and are liable to be overlooked and the seeds ripen before their presence is suspected.
7. For meadow or pasture make the soil very fertile, as most weeds will then be killed or crowded by the better grass and become of little account.
8. Modify the rotation of crops with reference to killing the weeds.
9. Make a specialty of hoed or cultivated crops.
