and move downward, killing both above-ground and below ground 

 parts. 



(e) For spot treatment control of dandelions, plantain, and curled 

 dock, apply the same solution used to kill wild onion and wild garlic. 

 Fasten a piece of kitchen sponge to the end of a stick or broom handle. 

 Dip the sponge into the solution and spot treat broadleaved weeds by- 

 pressing the moist sponge against the crown of each plant. Grasses 

 are not injured, and desirable plants nearby will not be injured if care 

 is used to avoid touching their foliage. This spot-treatment method 

 eliminates danger of spray drift and allows the operator to kill weeds 

 growing close to desirable flowers and shrubs. 



(f ) After applying spray materials that are absorbed through foliage 

 and translocated to other parts of the plant, delay mowing for 24 to 48 

 hours. Included in this group are 2,4-D, 2,4,5-T, and silvex. For mate- 

 rials that kill upon contact with foliage or are taken up from the soil 

 (PMA, DNBP, KOCN, and sodium arsenite), mowing and removal of 

 clippings before spraying may increase the efficiency of the treatment. 

 Rain or sprinkling shortly after treatment with some herbicides will not 

 decrease their effectiveness, but, as a general rule, avoid sprinkling for 

 24 to 48 hours. 



(g) Avoid spraying very young seedlings of lawn grass with herbicides. 

 After they have begun to tiller or spread by rhizomes they may be given 

 moderate herbicide treatments. 



SOURCE OF HERBICIDES 



Herbicides are sold under a number of trade names and some are not 

 always available from local garden supply dealers, but usually are avail- 

 able from agricultural chemical dealers. Local agricultural chemical 

 dealers also can help obtain these herbicides from the manufacturers if 

 they are not available locally. Calcium cyanamide may be obtained from 

 local fertilizer dealers. 



Carefully read the information on labels. The label on every trade- 

 name product indicates the name of the active herbicidal ingredient, the 

 amount of active ingredient in the product, and directions for mixing and 

 use. Follow directions of the manufacturer carefully in using herbicides on 

 lawns and turf.
