GENERAL PRODUCT INFORMATION


For bulk distribution: A complete copy of this product's label must be provided to the user upon delivery.
White vinegar is a non-selective herbicide. It must be applied in a localized manner, in the soil near the crown of the weeds, with an injector specifically designed for this purpose. The acidic properties of the herbicide provokes root burning of treated weeds. Product is fast acting and symptoms of weed deterioration are generally visible 3 to 7 days following treatment.
Suppressed weeds: Perennial plants with growth in tillers or compact tufts such as the Grass, Cyperceae (Sedges; Scirpus and Carex) and Juncaceae (rushes) families.

DIRECTIONS FOR USE
CRANBERRY
TIME OF INTERVENTION it is recommendable to treat weeds early in the season when they are young, at the beginning of their growth cycle and above all prior to seed development. In cultivated fields, begin treatment at the beginning of crop development when the plants are in bud break and bud swell stages.
During this time, circulating in the fields for treatment application will not damage plants. Avoid treatment during the hook stage (closed floral buds) and during flowering as these are critical developmental periods for cranberry plants. For late applications during fruiting, circulation can cause serious damage by trampling the fruit. The use of a footbridge is favorable in situations where treatment targets more than the weeds along field edges. Newly installed fields can be treated throughout the summer season.

DOSAGE AND APPLICATION CONDITIONS: apply 12% WHITE VINEGAR at a time when the soil water reserves are at a level comfortable for cranberry plants. The use of tensiometers in cultivated bogs allows adequate monitoring of the soil’s hydric state. The ideal tension for vinegar (12% White Vinegar) application is between -4 and -6 kPa. In drier soil conditions the risk of phytotoxicity in cranberry plants is high. Dilute the 12% WHITE VINEGAR to obtain a weaker concentration of 6-9% when tension is ≤ -6 kPa. Do not apply when soil is very dry (≤ -7 kPa). It is very important to avoid application during extreme heat as plants are already under hydric stress at such times. High levels of humidity in the soil result in a probable loss of efficacy because the soil water will act as a dilutant. Strong precipitation after treatment brings the risk of dilution of the product. Never apply when the soil is very humid or wet (0 to -3 kPa) or in rainy conditions.
For small tillers of approximately 7 cm diameter or less, one injection per plant is usually sufficient. For larger tillers, a minimum of 2 to 3 injections per plant is necessary. All injections must be made in the center of the tiller at a depth of approximately 6.5 cm. During injection, keep the injector in the soil and avoid product rising to the surface. It may be necessary to repeat application 7 days after the first treatment, depending on soil conditions as well as the size and maturity of the treated plant.

DESCRIPTION OF INJECTION TOOL: the injection tool is composed of a stainless steel shaft with an outward diameter of 9.5mm (3/8 inches) and an interior diameter of 5.5 mm (7/32 inches) the length of
Last approved label: 2018-3408, dated 2019-02-14 which is 86.4cm (34 inches) ending in a pointed tip. The tip must be removable in order to be changed when worn. The tip is equipped with two openings allowing the expulsion of the liquid. The two jets have a diameter of 1.6mm (1/16 inches) and are located on opposite sides 19mm (¾ inches) from the tip end. The injection shaft is linked to a discharge valve by a transparent plastic tube with an interior diameter of ¼ inches. Watertight joints are used to connect each element together. The injector much be calibrated in order to insure the injection of 35 to 40 ml of white vinegar per injection at a pressure rate of 240 to 275 kPa (35 to 40 psi).
For minor interventions, this tool can be attached to a hand- held or backpack sprayer. It is also possible to use a system allowing several people to work simultaneously. This system is equipped with an opaque white reservoir made of high density polyethylene and placed on a mobile platform. The reservoir contains white vinegar and is connected to spray equipment using a ground boom. Multiple injection tools are attached along the pesticide boom in place of spray nozzles. It is possible to assign one worker per injection station with a maximum of 3 to 5 workers along the boom. This system functions with the aid of a 12 volt plastic pump resistant to corrosion.

CAUTION: white vinegar is phytotoxic to cranberries. Primary symptoms of phytotoxicity are chlorosis or parching of cranberry plants:
Avoid all contact with cranberry plants.
Under no circumstances should the product be used in foliar spraying:
DO NOT use as a broadcast spray on foliage with a boom or air blast sprayers
DO NOT apply this product through any type of irrigation system.
DO NOT apply by air.
Applications should be completed solely in a localized manner and only with the soil injection system specifically designed for this purpose.
Ensure that the liquid has been completely inserted in the soil before removing the injection shaft.
Ensure water tightness of the injection tool in order to avoid dripping of vinegar solution on cranberry plants or leaves as the device is moved around the field.
Avoid treatment when the soil is very dry or in extreme heat.
Treat highly infested areas progressively as the cranberry plants are at greater risk when weed density is high.
Avoid treating annual weeds as well as single-stem perennial weeds such as horsetail, couch grass, rice cut-grass, goldenrod, St. John’s Wort, rorippa sylvestris, spiraea spp, vetches spp, potentilla and many species of small trees (birch, willow, poplar, and maple spp). For such plants, the efficacy rate is variable and uncertain and the risk of phytotoxicity to cranberry plants is high when dealing with single-stem weeds rather than tillers.
