GB2407246A - A method of selective application of herbicides to a plant - Google Patents

Abstract

A method of selective application of chemical substances such as herbicides to a plant or part of a plant. The weed killer is supplied in a paper, plastic or foil sachet in liquid form or as a gel or a powder. In use, the growing point of the plant to be treated is inserted into the open sachet and the neck of the sachet squeezed around the stem of the plant. This holds the sachet in position, and prevents the loss of chemical by spillage.

BIND WEED KILLER

This invention relates to a method of applying poison to Bindweed.

Bindweed is universally detested by gardeners. It is unsightly; it grows at a phenomenal speed; it is difficult to unravel without damaging the host plant; a tiny bit of root remaining grows again; It spreads with alarming speed.

One method adopted by gardeners is to dip the growing point of the plant in a bowl containing a systemic weed killer. That is to say a weed killer which is absorbed by the plant and on reaching the roots kills the plant at its roots.

This method has a number of associated problems: 1. Carrying open containers of weed killer around the garden may well lead to spillage on plants you wish to keep.

2. Absorption will depend somewhat on moisture and temperature and length of immersion.

3. Unless the gardener is very methodical, it can be extremely difficult to remember exactly which weeds have been treated and which hadn't.

According to the present invention all the above problems can be overcome.

The weedkiller; made as specific bindweed killer as possible; is packed as a viscous liquid in a sachet. Each sachet containing sufficient poison to kill one plant. The gardener would tear open the sachet and place the growing tip of the bindweed into the sachet bending the weed head over and keeping the sachet upright.

The sachet would be made of a material that could be pressed together on either side of the now immersed stem to hold the sachet in place. Such materials are readily available in both foil and paper coated materials and would be a matter of selecting that which is compatible with the poison. (No claim is made for this material) The sachet would be coloured green although doubtless will have to bear some print matter under EU law. Such warnings and so on might be on the section torn from the sachet when opened. None the less it should be possible to make the sachet green and thus not too visible, but visible enough to see that the plant is being treated. v-)

The fact that the growing tip is also denied light should largely eliminate further growth as well as speed up the absorption of the poison.

Claims (1)

1. It is claimed that as a means of killing weeds and specifically Bindweed that individual portions of weedkiller physically attached to the growing plant is an entirely new and original concept.
