Comments and precautions . --Avoid application of herbicides to grape 

 foliage and to young vines that have not developed a coating of loose 

 bark. Grapes are extremely sensitive to phenoxy herbicides, such as 

 2,4-D, 2,4,5-T, silvex, MCPA, and others. Do not use spray equipment 

 that has been used to apply phenoxy -type herbicides to other crops unless 

 equipment has been thoroughly cleaned and is known to be free of these 

 herbicides. 



Strawberries 



Varietal responses to herbicides vary and must be determined locally 

 in each case. 



(1) For weed control on full-year basis: (a) Preplanting treatments (10 to 

 15 days before transplanting)- -DNBP at 8 to 10 pounds, CIPC at 4 to 8 

 pounds, 2,4-D at 2 to4 pounds, or sesone at 3 to 6 pounds in 10 to 40 gallons 

 of water per acre on soils prepared in advance where soil types permit, 

 (b) Post-planting treatments of sesone 14 to 21 days after transplanting and 

 at intervals thereafter as needed. Cultivation should be avoided during the 

 period between preplanting treatment and transplanting. Cultivation should 

 precede each sesone treatment until runner production limits cultivation. 



(2) For control of broadleaved weeds and seedling annual grasses from 

 2 to 4 weeks after setting until fruit-bud differentiation begins: 2,4-D at 

 l/2 to 1 pound per acre applied as a selective foliage treatment. 



(3) For fall and winter weed control when strawberries are dormant: 

 DNBP at 1 to 2 pounds will control broadleaved weeds, and CIPC at 2 to 4 

 pounds in 40 gallons of water will control chickweed and winter annual 

 grasses. 



FLOWERS AND ORNAMENTALS 

 Gladiolus, Dutch Iris, Narcissus 



(1) Pre -emergence . --For control of annual grasses and broadleaved 

 weeds: 2,4-D at 2 to 4 pounds, sesone at 3 to 6 pounds, CIPC at 4 to 8 

 pounds, DNBP at 4 to 8 pounds, TCA at 6 to 10 pounds; combinations of 

 CIPC at 4 pounds with sesone at 3 pounds or 2,4-D at 2 pounds per acre; 

 or combinations of TCA at 6 pounds with sesone at 3 pounds or 2,4-D at 

 2 pounds--in 20 to 40 gallons of water per acre applied just prior to emer- 

 gence. Effective for 30 to 60 days or more. 



(2) Post- emergence. --Sesone at 3 to 4 pounds in 20 to 40 gallons of water 

 per acre applied 30 to 60 days after pre-emergence treatment but before 

 weeds begin to emerge will usually extend period of weed control until 

 harvest. Amine salts of 2,4-D at rates up to 1 pound per acre may be used 

 as a post- emergence spray if applied before leaf blades open. Sesone is 

 less likely to cause injury than 2,4-D as a post-emergence spray. 



Established Evergreen and Deciduous Plants 



(1) For control of annual grasses and broadleaved weeds in rows of 

 coniferous transplants and deciduous stocks: Sesone at 3 to 6 pounds or 

 CIPC at 4 to 8 pounds in 20 to 40 gallons of water per acre applied as a 

 basal-directed spray. For maximum effectiveness, both herbicides should 

 be applied prior to weed emergence or to clean cultivated soil. Also,
