METHOD OF TREATING PLANTS WITH HEAT TO STIMULATE EARLY UNIFORM BUD BREAK The following statement is a full description of this invention, including the best method of performing it known to us: METHOD OF TREATING PLANTS WITH HEAT TO STIMULATE EARLY UNIFORM BUD BREAK FIELD OF THE INVENTION This invention relates to a process for stimulating "bud break" for plants such as Grapes, Kiwi Fruit, Apples, Blueberries, Nectarines, Peaches, Plums and similar deciduous fruit trees.
BACKGROUND OF THE INVENTION Climatic conditions can greatly affect the process known as bud break. If plants such as Grapes, Kiwi Fruit, Apples, Blueberries and similar type plants do not receive sufficient cold temperatures in winter, the buds do not break uniformly in Spring. Uneven or delayed bud breaks can cause crop reduction, uneven size development and economic harm to the farmer.
Commercial chemicals such as Dormex
T
m are currently used to stimulate early and uniform bud break. Unfortunately, these chemicals are noxious to workers and the environment.
SUMMARY OF THE INVENTION It is an object of this invention to provide a novel method for inducing early and uniform bud break in plants including Kiwi Fruit, Apples, Blueberries and similar plants by applying rapid burst of intense heat to the unopened buds early in the Spring to thereby precisely control bud break.
It is a more specific object of this invention to provide a method of stimulating controlled bud break in early Spring in plants including Kiwi Fruit, Grapes, Apples, Blueberries and similar plants by applying heat through a medium to unopened buds for a predetermined period of time. The heat transfer medium includes heated air, heated liquid, heated foam and permits uniform and early bud break.
DESCRIPTION OF THE PREFERRED EMBODIMENT Delayed or uneven bud break for Grape vines, Kiwi vines, other fruit bearing vines, fruit bearing bushes and trees can cause crop reduction resulting in economic harm to farmers. Delayed or uneven bud breaking occurs when these fruit bearing bushes, vines and trees are not exposed to sufficient cold temperatures in the winter. Commercial chemicals such as Dormex T M are currently being used to stimulate early bud break but such chemicals are noxious and dangerous.
In an embodiment, heat is transferred from a mobile apparatus through a medium to the unopened buds at sufficient intensity to cause early and uniform bud break. The heat transfer medium is applied to the unopened buds and in early Spring and includes heated air, heated liquid, heated water and heated foam.
Suitable Mobile Equipment for applying the heat transfer medium will direct the heated medium on the unopened buds for a sufficient time to cause bud break without damage to the plant. The time the unopened buds will be exposed to the heat medium will vary with the characteristics of the medium. For example, heated air dissipates heat rapidly while heated liquids retain their heat longer. Hot foam retains its heat even longer and does not require the same residence time as hot air or hot liquids.
It has been found that the heat transfer medium should be within the range of 40 0 C to 300 0 C in order to effectively stimulate bud break while avoiding damage to the plant. The heat transfer medium should be applied in a controlled fashion to the unopened buds. It has also been found that the heat transfer medium should be applied to the unopened buds for a period of time within the range of one half to sixty seconds depending on the climatic conditions, the kind of plant, the heat transfer medium, etc. When hot air is used, the residence time the exposed unopened buds are subjected to this heated air will range from about one half second to one minute depending on the temperature of the heated air. When hot liquid is used, including hot water, the unopened buds are exposed for a period of about one second to about thirty seconds. When hot foam is used, the residence time of exposure will be from about ten seconds to about one hour. However, the foam may remain in the plant for up to several hours.
The use of all of the heat transfer media permits early controlled bud break without substantially any harm to the plants. The heat applied to the external protective covering of the buds simulates the arrival of Spring and the plant's physiology responds by energizing the buds to break open.
4 From the foregoing description, it will be seen that the present invention provides a novel method of stimulating early uniform controlled bud break by applying a heat transfer medium to the unopened buds without substantially any attendant danger to the plants.
Claims (6)
1. A method of stimulating early and uniform bud break in plants including low-lying shrubs and bud-bearing trees, comprising subjecting the unopened buds of the plants to a heat transfer medium selected from a group including heated air, heated liquid and heated foam; and having a temperature within the range of about 400C to 3000C for a predetermined period of time within the range of about one half second to one hour, wherein heat is transferred from a mobile apparatus through said medium to the unopened buds.
2. The method as defined in claim 1 wherein the heat transfer medium is hot air.
3. The method as defined in claim 1 wherein the heat transfer medium is hot water.
4. The method as defined in claim 1 wherein the heat transfer medium is a heated foam.
The method as defined in claim 1 wherein the plants include Kiwi Fruit, Apples, Blueberries, Grapes and similar vine, shrub and deciduous trees.
6. The method of claim 1 substantially as hereinbefore described. Dated this 19 th day of May 1999 DEBRANA PTY. LTD. 010 835 140) By their patent attorneys CULLEN CO.
