(b) Flowers, shrubs, and trees may be damaged by spray drift or 

 vapors, ■which may be avoided by spraying ■when wind velocities are low. 

 Use only salts or low-volatile esters of 2,4-D, 2,4, 5-T, or silvex. All 

 herbicides available for ■weed control in la^wns should be used according 

 to manufacturer's directions. 



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

 apply the sanne 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 cro^wn 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 elinninates danger of spray drift 

 and allows the operator to kill weeds growing close to desirable flo^wers 

 and shrubs. 



(d) 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 

 (DNBP), 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 gen- 

 eral rule, avoid sprinkling for 24 to 48 hours. 



(e) Avoid spraying very young seedlings of la^wn 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. They are not al^ways 

 available from local garden supply stores, but usually are available from 

 agricultural chemical dealers, or at least obtainable through them from the 

 manufacturers. 



Read the labels carefully . The label on every tradename product indi- 

 cates 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 la-wns and 

 turf.
