Weed wiper +

The hand held weed wiper +has been especially developed for the selective application of herbicides.

The weed wiper + has significant advantages over conventional methods of application such as knapsack sprayers for spot applications or treating sensitive areas. The concentrated herbicide within the weed wiper +is applied only to those plants that the rope wick comes into contact with. By moving the weed wiper + over the leaves of a weed, a small dose of herbicide is transferred to the target weed with the surrounding plants uncontaminated.

The weed wiper + is ideal for treatment of weeds in row crops, vegetable gardens, between grape vines, around trees, or any other place where conventional treatment would be too dangerous or difficult.

Operating principle

The weed wiper + is recommended for use with systemic herbicides and is particularly suitable for use with herbicides having glyphosate as the active ingredient. A single wipe of the concentrated herbicide is enough to kill most weeds.

The weed wiper gives excellent results when used on individual weeds or clumps of weeds. First signs of effect will generally be seen 1-2 weeks after treatment. Complete control may take up to 6 weeks.

Systemic herbicides are taken up through the leaves and green stems, entering the sap stream to be trans-located to the roots, thereby killing annual as well as perennial weeds. It is therefore essential that the sap is moving freely in the plant, and, for this to take place, the plants must be actively growing. For best results, the weed should be treated on both sides using a sweeping backwards and forwards motion.

Weeds to be treated must therefore be green, dry, healthy and actively growing. The effectiveness of treatment will be reduced if the plant is under stress from drought, water logging, disease or old age.

Grasses should be treated when they have full emergence of leaves.

At least 6 hours free of rain must follow treatment to ensure that the herbicide is taken up by the plant.

Very well established weeds in large clumps or dense weed mixtures may need more than one treatment. Re-treatment is usually best made 2-3 month after the first application. If previously hidden untreated weeds are seen to be thriving, immediate treatment is advisable.

In order to help identify treated plants, it is useful to add a dye e.g. coloured food dye.

Adjustment of the flow rate of the weed wiper + depends on the conditions. For example, for treatment of large areas with large dense weeds it is often necessary to increase the flow rate. This is done by loosening the two caps where the rope wick enters the weed wiper + and loosening the filler cap. For areas with less of a weed problem, the flow can be restricted by tightening the two caps.

During treatment, the flow may be reduced if a vacuum is formed in the handle with the filler cap tight. If the weed wiper + is shaken or turned upside down for a few seconds, this will allow sufficient air to enter the weed wiper + to restore the flow. Alternatively, the filler cap can be loosened when the weed wiper + is in the working position to eliminate a vacuum in the handle.

Safety

The operator must wear suitable protective clothing, such as rubber boots, overalls and protective gloves when using the weed wiper +.

Do not walk across freshly treated areas, as herbicide may be transferred by footwear or clothing.
