Grapes 



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

 and broadleaved weed beneath trellis: Oil-water emulsion of CIPC and DNBP. 

 A mixture of 6 to 10 pounds CIPC, plus 1 pound of oil-soluble DNBP in an oil- 

 w^ater emulsion (10 gallons of oil plus 40 gallons of water) applied to an 18- to 

 24-inch band on each side of the trellis at the rate of 50 gallons per acre will 

 give excellent control of emerged grasses andbroadleaved weeds. The contact 

 action of DNBP kills the emerged annuals and the CIPC provides residual 

 pre-enaergence weed control. 



(2) Soil treatment . --For control of Johnsongrass and Bernnudagrass under 

 trellises in western grapes grown under irrigation: Spot spray with dalapon 

 using 1 pound to 10 gallons of spray solution. 



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, and MCPA. Do not use spray equipment that has been 

 used to apply phenoxy-type herbicides unless it has been thoroughly cleaned 

 and is known to be free of these-herbicides. 



Stra'wberries 



Varietal responses to herbicides vary and must be determined locally in 

 each case. i . 



(1) Post -planting. - -For weed control on a full-year basis: Post-planting 

 treatments of sesone at 3 to 6 pounds, or a combination of sesone at 2 pounds 

 plus CIPC at 1 pound applied in 20 to 40 gallons of water per acre 14 to 21 

 days after planting and thereafter as needed at intervals of 4 to 8 weeks. Clean 

 cultivation should precede each application until runner production limits culti- 

 vation. 



(2) After harvest .- -For control of established broadleaved weeds after 

 harvest is completed: 2,4-D at 1/2 to 1 pound applied in 10 to 40 gallons of 

 water. Limit to a single application per summer. 



(3) During dormancy . --For fall and w^inter w^eed control when straw^berries 

 are dormant: Sesone at 2 pounds plus CIPC at 1 pound will control germinating 

 chickweed, henbit, wild vetch, and annual bluegrass; DNBP amine salt at 1 to 2 

 pounds will control chickweed and germinating winter annual grasses. 



TREE FRUITS 



Apples, Cherries, Peaches, Pears, Plums 



(1) For control of annual broadleaved weeds and weed grasses: One pound 

 of oil-soluble DNBP plus 6 to 8 pounds of CIPC dissolved in 10 gallons of fuel 

 oil and 40 gallons of water (a total of 50 gallons of spray per acre) to be applied 

 in early spring so as to just miss the base of the tree.
