HOW TO CONTROL WEEDS COM
 MON IN ARK ANSAS


 Farmers must expect to use meth ods to check rather than to complete ly eradicate weeds that are common in Arkansas, says Martin Nelson. Vice-D Dean and Director, University of Arkansas ard Experiment Station. He points out that good farming which involves returning manure to the land invariably restocks the fields with weed seed, thereby making continuous effort necessary Following are his recommendations for controlling some of the noxious weeds in Arkansas. Recommendation for other weeds will appear next week.
 The cookie bur grows persistently in cultivated fields, especially on rich soil, in every section of the state It will come on in corn fields when the crop has been '1aid by, follow ing perfectly clean cultivation, and produce on rich soils a remarkable growth and quantity of seed. The ripened burrs cling to the hair of live stock most stubbornly and are later scattered over the farm. Young pigs grazing on newly germinated cookie burrs are poisoned frequently and die. Methods of eradication may be three in main:
 CD Clean cultivation all season pre- venting growth. (2) Seeding to small grain crops such as oats or wheat, blowing the land after harvest and seeding to cowpeas or soybeans to be cultivated, or to sorghum sown broad cast for hay. Repeat until the field is clean. t3l Seeding to meadow, pre- ferably alfalfa when cuttings are frequent enough to prevent seed from being produced.
 Plantain, especially "Buckhorn' ; and Large Bracted Plantain" grows persistently in the state. These and other species of pfantain infest mead ows and pastures to very objection able degree. Method of eradication: (1) Sow clean seed. (2) Flow up mead ow, plant titled crops and practice clean cultivation. (3) Flow up, seed to winter grain: blow up again after harvest and SOW to cowpeas or soy beans for clean cultivation, or sor- ghum sown broadcast for hay. Re- peat until the field is clean.
 Dock, broad-leaved, curled-leaved, and willow-leaved grow in meadows, pastures, farm yards and waste places. They prefer moist rich soil. They are thrifty growers, crowd out other veg citation and produce seed abundantly. In meadows the plants may be moved with the hay crop early enough to prevent seeding, repeating the now ing to catch the seed stocks before seed ripens. If the weeds grow ahead of the hay crop it becomes necessary to use hoe or spud. In pasture lots the plants must be cut out with hand implements to destroy them. As a rule, when cut below the surface these plants will be killed. Where seed has been produced and fallen, new plants will come on for year or two and must be cut out diligently with hand implements.
 Sorrell is persistent weed trou- bling most on. upland thin soils, es- pecially those that have become sour Sorrell persists in meadows and now ing is ineffective. On land justifylng improvement, treatment of lime to correct acidity and the application of manure to increase productivity are necessary steps in eliminating the weed. It is not troublesome on rich soil; besides the increased fertil- ity will produce heavier growth of crops to choke 1t out In case grain crop is grown, land should be plowed following the harvest and sown to COW peas or sorghum broadcaAt to choke out the sorrell. In titled crops, clean cultivation is effective.
 Dodder, slender orange colored vine, grows freely in clover and alf- alfa fields and on weeds along the roadside and waste places. When well started, the plant depends entire ly upon the host for support, becomes entirely parasitic and disconnects itself with the soil. Moving the crop of clover or alfalfa or weeds before the dodder has begun to ripen seed, usually proves effective. If later growth comes on 1t should be treated in the same way. In case seed has been produced, the material should be moved and when dry burned on the spot where it grew.
