Abstract

Description
Horticultural Device
This invention relates to a new device for the application of horticultural chemicals.
It is known to apply horticultural chemicals, eg fungicides, pesticides, etc. in smoke formulations. Such smoke formulations are particularly used, for example, in fumigating glasshouses. However, these products are difficult to formulate, unpleasant to use and are usually of low efficiency because the very high temperature used in creating the smoke will often degrade the active chemical.
Although electrical devices are known which use a gentler heat source to vaporise chemicals, these require electrical supplies to glasshouses which are undesirable and expensive for the amateur gardener and also require careful insulation.
We have now found a new device suitable for the sustained release of horticultural chemicals which overcomes or mitigates the aforementioned problems.
According to the invention we provide a device for the sustained release of a horticultural chemical which comprises a reservoir adapted to hold the horticultural chemical and supported by a frame which frame is adapted to house a non-electrical heat source adjacent to the reservoir. The reservoir is positioned such that in operation
convection transfers the heat from the heat source to the reservoir. The reservoir a preferably situated in such a position that in operation it or a substantial portion of it is situated above the heat source. The frame may be, for example circular or square in cross-section and comprises a side walled chamber, base plate and an end wall, eg an upper wall, provided with a reservoir. The base plate and the end wall may be integral parts of the frame or they may each be separate. The chemical may be a solid, eg. tablet, powder or granules; or a fluid, eg. liquid, solution or suspension. In addition, the chemical reservoir may be a metal tray, eg a tin plate or alternatively when the chemical is in a fluid form a porous block impregnated with the chemical. The heat source may comprise any conventional non-electrical heat source such as a candle or a paraffin burner, using eg. paraffin or methylated spirits. In small scale devices we especially prefer the heat source to be a candle in the form of a "night light", this provides sustained, eg eight hours, vaporisation of the chemical. In large scale devices we prefer a paraffin or methylated spirit burner, although other fuels, eg petrol or gas could be used. When a naked flame is used the frame may be solid, eg a metal wall, which would reduce drafts. However, it may also be useful to provide the frame with
ventilation means, eg one or more air holes suitably positioned to provide air for combustion without causing drafts. The holes are preferably positioned in the side walls of the frame adjacent to the reservoir thus reducing drafts on the flame.
It may be desirable to vary the heat applied to the reservoir depending upon the heat of vaporisation of the chemical and the desired rate of release of the chemical. To achieve this the size of the heat source may be varied, eg. a larger candle or paraffin burner may be used. The heat applied to the reservoir may also be varied by varying the distance between the heat source and the reservoir. The frame and especially the base plate of the frame may be adjustable in order to vary the distance between the heat source and the reservoir. Also, the frame, or alternatively the base plate may be provided with an internal chimney which directs the heat from the heat source onto the reservoir. In order to reduce heat loss the chimney and/or the frame may be thermally insulated. Thermal insulation may also be used between the heat source and the reservoir if the chemical is thermally sensitive. When a naked flame is used the safety of the device may be improved by the inclusion on the frame, or preferably in the base plate, of means for supporting the heat source. In the case of a candle such support means may be, for
example, a metal surround or a spike. For prolonged burning of a candle a sealed metal surround is to be preferred which would facilitate the burning of all of the fuel eg. wax. The safety may be further enhanced by surrounding the support means with a fire resistant or fire extinguishing means. We particularly prefer to surround the support with water so that if, for example, the wick of the burner were to fall, the flame would be extinguished. The invention may be used in relation to any vaporisable chemicals, and especially pesticides, eg. insecticides and acaricides; fungicides and herbicides, or a combination of one or more of these chemicals. Specific chemicals which may be mentioned include permethrin, tecnazene, lindane, pirimiphos methyl, pirimiphos ethyl, pirimicarb, phoxim, carbendazim, fenarimol, fenamiphos, dichlofluamid and dicofol.
The invention is useful for the application of chemicals in confined spaces such as glasshouses. However, the invention may also be useful in open spaces, for example, the device may provide an attractive insect repellent for use, eg at barbecues.
The amount of horticultural chemical used may vary according to the nature of the chemical, the pest to be treated and the area to be treated. It is most important that an effective amount of chemical is applied. We prefer
to apply from lmg to lg per 3 of treatable area, preferably from lmg to 500mg per m3, more preferably lmg to 150mg per m3, most preferably lmg to lOOmg per m3 and especially lOmg to 50mg per m3. We especially prefer insecticides such as permethrin or lindane to each be applied in a concentration of from lOmg to 50mg per m3, more preferably lOmg to 25mg per m3, eg 13 to 14mg per m3. Herbicides such as tecnazene may preferably be applied in a concentration of from lOmg to 200mg per m3, more preferably lOOmg to 200mg per m3, eg 140-145mg per m .
According to the invention we also provide the use of a device according to the invention for the destruction or moderation of horticultural pests. By the term pests we mean, insects, arachnida, fungi and weeds, but especially insects and arachnida and most importantly insects.
We also provide the use of a horticultural chemical for the destruction of horticultural pests by sustained release in a device according to the invention. Such use comprises placing the chemical in the reservoir and igniting the heat source such that vaporisation of the chemical can occur.
It is also within the scope of this invention to provide a pack comprising a device according to the invention in combination with a horticultural chemical. In
addition the pack may optionally comprise a non-electrical heat source eg. a candle.
The invention will now be illustrated with reference to the following drawings in which Figure 1 is a sectional view of the device provided with a metal tray reservoir and Figure 2 is a sectional view of the device with a porous block reservoir.
Referring to Figure 1, a chemical vaporisation device is provided with a heat source in the form of a candle (1) housed in a candle support (2) positioned on a base plate (3) . The base plate (3) is filled with water (4) and supports a frame (5) , which frame is provided with ventilation means (6) and supports a reservoir (7) . The reservoir (7) contains a horticultural chemical (8) . The frame (5) is, optionally, provided with thermal insulating material (9) for thermally sensitive chemicals.
Referring to Figure 2 the reservoir (7) is replaced by a porous block (10) impregnated with chemical.
In operation the heat from the candle (1) vaporises the chemical (8) to provide a sustained release of the chemical for as long as the chemical and/or the candle lasts.
