Second application- -2, 4-D treatment should be delayed until new canes are tall enough 

 to permit directed basal application without getting spray on cane tips. All basal 

 directed contact sprays should be applied when weeds are small. 



(2) For control of winter annual grasses and broadleaved weeds in fall or early 

 winter: CIPC at 4 to 8poundsin20 gallons of water per acre prior to weed emergence. 

 Particularly effective also in controlling chickweed after emergence. 



(3) In recent preliminary research investigations, monuron at 1 to 3 pounds in 50 

 gallons of water per acre applied to clean cultivated soil in the dormant season has 

 given control of annual grasses and broadleaved weeds without significant injury to the 

 crop. 



Comments and precautions. --Do not use 2, 4-D in brambles during blooming stage. 

 Suitable mulches will aid in reducing weed problems, but mulching costs are usually 

 high. Bramble crops are tolerant to a number of herbicides. 



Grapes 



(1) For control of annual grasses and broadleaved weeds beneath trellis: Oil-water 

 emulsion of CIPC and DNBP. A nnixture of 6 pounds CIPC plus 1 pound of oil-soluble 

 DNBP in an oil-water 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 and broadleaved weeds. The contact action 

 of DNBP kills the emerged annuals and the CIPC provides residual pre-emergence 

 weed control. 



(2) In recent research studies, monuron applied prior to weed emergence at 2 pounds 

 in 40 gallons of water per acre as a soil treatment in the dormant season gave effective 

 control of annual grasses and broadleaved weeds in mature vineyards. One application 

 per year is usually adequate. 



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, 2-{2,4,5-TP), MCPA, and 

 others. Do not use spray equipment that has been used to apply phenoxy-type herbi- 

 cides to other crops unless equipment has been thoroughly cleaned and is known to 

 be free of these herbicides. 



Strawberries 



(1) For weed control on full-year basis: Preplanting treatments (10 to 15 days before 

 transplanting) --DNBP at 8 to 10 pounds, CIPC at4 to 8 pounds, 2, 4-D at 2 to 4 pounds, 

 or 2,4-DES at 3 to 6 pounds in 10 to 40 gallons of water per acre, followed by post- 

 planting treatments of 2,4-DES 14 to 2 1 days after transplanting and at intervals there- 

 after as needed. Do not cultivate during tiie period between preplanting treatment and 

 transplanting. Cultivation should precede each 2,4-DES treatment until runner produc- 

 tion 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 1/2 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 winter annual broadleaved weeds and grasses.
