Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates generally to a method and apparatus for non-toxic control of white fly and other small pests that adhere to crops during the growing and harvesting stages, and in particular, to insects without destroying the crops. Hot and high pressure hot water and air, such as to kill their eggs and larvae,
It relates to a method and a device for dosing over a period of time and to the control of weeds.

[0002]

BACKGROUND OF THE INVENTION One of the most difficult problems faced by farmers is controlling pests that attach to crops during the growing and harvesting stages. Traditionally controlled by the use of pesticides, the use of pesticides has been found to be toxic to other crops and animal species, including humans. Pesticides often penetrate into groundwater and can travel around crops, harming the entire environment surrounding them. Moreover, pesticides are not a solution for controlling all pests. Certain pests are affected by pesticides, but other pests in the area may not be affected, which can also have an adverse effect on beneficial insects. Insects can mutate and become resistant to pesticides.

A good example of an insect that is not affected by many insecticides is the white fly, and in 1991 alone, damage from white fly on agricultural products throughout the United States has risen to over $ 500 million. See Perring et al., “Evidence of a new species of white fly (Evid
ence Fora New Species of Whitelfy) ("UCR Findings and Implication
s) ", California Agriculture
Journal, January / February 1993, p. 7). White flies harm crops by transmitting disease, eating them, and polluting them with viscous sugar.

[0004] The difficulty in controlling whiteflies lies in their strength and their ability to tolerate insecticides. First, in many cases,
White fly predators are controlled by artificial destruction of wetlands and ponds, which are homes for beneficial predatory insects, or by the continuous use of pesticides and herbicides. In addition, white flies have demonstrated the ability to create waxy enzymes that block the penetration of traditional insecticides. Moreover, they have
It is mutagenic and, when exposed to several generations of pesticides, can adjust its internal chemical balance to become resistant to pesticides. Lastly, coupled with the tendency to not spontaneously move away and accumulate on host crops, the rapid regeneration rate is of great numerical strength.

However, white flies have several weaknesses that can be exploited in an attempt to control their population and eliminate them from crops. For example, white flies are terrestrial insects and do not live underground. In addition, the volume of the body is very small. Their primary source of protection is the waxy covering described above. The body is soft and is a good source of food for many types of predatory insects. White flies also tend to settle. That is, their life cycle is adapted to the life cycle of the host's food (field and planted crop) production capacity. As is common to all living organisms, the viability of whiteflies depends on their ability to maintain body temperature within plus or minus a constant temperature of their adaptive range.

Spraying warm water at ゜ C to 65 ゜ C for 0.2 seconds revealed that the crops were not damaged when contacted and that insects were killed. In all but one experiment, water, a chemical or household soap, was added. Brezinski and others recognized that the use of hot water could control insects, but the temperature, time, and equipment required to control large-scale white flies and other pests economically viable without damaging crops. No other parameters were considered.

Further, US Pat. No. 5,297,730 to Thompson describes the use of warm water to control weeds and lowering with insects. Thompson has recognized that warm water is useful for controlling insects, but acknowledges that he has also eliminated crops. Thus, the crops are destroyed along with the insects, so the Thompson method and apparatus cannot be used to combat insects from the crops.

Therefore, as can be seen from the above description,
Clearly, there is a need for a method and apparatus for non-toxic control of white flies and other small pests on crops during the growing and harvesting stages. The method must be capable of effectively controlling all pest populations in the handling area without harming the growing and harvesting crops. It must also avoid the use of pesticides and other chemicals that can destroy the environment, including groundwater, and that any variation in the physical or chemical properties of the pests will not hinder the effectiveness of the treatment. It must be something that can be prevented. It should not adversely affect the long-term activity of pollinating or beneficial predatory insects. Furthermore, the materials, equipment and energy requirements used in the method must be such that the process can be made economically viable in terms of cost. The present invention meets these requirements.

[0009]

SUMMARY OF THE INVENTION In accordance with the present invention, there is provided a method and apparatus for non-toxic control of white flies and other small pests that adhere to crops in the growing and harvesting stages. The method of the present invention effectively combats all pest populations in the handling area without harming the growing and harvesting crop. This method does not use pesticides or other chemicals that can destroy the environment, especially groundwater. The method of the present invention also prevents the pest from interfering with the treatment effect due to a variation in the chemical properties of its body. The method of the present invention does not adversely affect the long-term activity of pollinating or beneficial predatory insects.
The materials, equipment and energy requirements of the method and apparatus of the present invention can make the method economically feasible to achieve the desired objective in terms of cost.

The present invention is intended to effectively control white flies and other small pests attached to crops at the stage of growing and harvesting by using hot air and hot water separately or in combination. The present invention takes advantage of the differences between the mass and nervous systems of the pest and the crop being treated. That is, insects, due to their low mass, quickly absorb heat in water and air, raising body temperature much faster than crops to viable temperatures. Crops at the harvest and growth stages targeted by the present invention generally have a larger mass and slower neural response than the pests, so there is no adverse effect associated with the administration of hot water and hot air according to the present invention.

According to the present invention, low-pressure water preheated to a temperature at which the body temperature of the pest can be higher than the viable temperature,
An apparatus is provided that is configured to spray crops that are in a harmful growing and harvesting stage.

The hot water is sprayed over a period during which the body temperature of the pest is above the viable temperature, but for such a short period that does not exceed the viable temperature of the crop. The volume of the pest is
Because much smaller than crops, the insecticidal temperature was about 66-77 ° C (150-170 ° F) and the duration was found to be within a few seconds. However, the temperature and the period vary depending on the kind of insect and the kind of crop.

In another preferred embodiment of the present invention, hot air is used to control insects flying over the crop. By using warm air in combination with warm water sprayed on the crop itself, insects, larvae and eggs attached to or near the crop can also be controlled. In another preferred embodiment, weeds, insects, larvae and eggs remaining in the soil are destroyed by blowing hot air directly onto the uncultivated soil.

The method of the present invention is advantageous in that it has been found that both the present and the next generation of insects can be controlled. By spraying with hot water according to the present invention, not only adults can be controlled, but also eggs and larvae can be injured. Thus, the method of the present invention, which controls pests throughout the developmental stages, is most effective when the pests have fully grown during a particular season.
For example, treating a field that has suffered pest damage immediately before cultivation and replanting will result in little or no crop damage in the following season. In the case of white flies, white flies are surface-living insects and their eggs, which are present from the next season, are largely dependent on the fact that they are dormant until a new good source is obtained.

By practicing the method of the present invention, unwanted insects can be successfully controlled without using pesticides. The present invention is chemical-free and does not affect the immediate environment or groundwater of the pest-affected crop. This is a very important aspect of the present invention, as all conventional methods for controlling or controlling pests that attach to crops during the growing and harvesting stages use some kind of chemical means. Side view.

[0016] Other objects, features and advantages of the present invention will become apparent from the following detailed description.

1 and 2 show a specific embodiment of the present invention. In the figure, a vehicle (10) has warm water (1) on crops and trees (14) and their surroundings in the growing and harvesting stages.
2) and includes a curved body (16) having an interior (18) similar to a pruning vehicle, as will be apparent to those skilled in the art. The vehicle (10) can be driven to cover crops and trees (14) during the growing and harvesting stage. The two corners (20) of the vehicle are each rounded so that the sharp corners do not catch on the branches when the vehicle (10) passes over the trees. The vehicle (10) is further provided with a driver's cab (22) on an upper part thereof, so that the driver can suitably drive while sitting. The vehicle is powered by an engine (24) that transmits torque to a driven shaft (26) and transmits to all four wheels (30) via a universal gear (28). The engine (24) may be a six-cylinder engine or a diesel engine. Further, it can be attached to a trailing water tank truck (not shown) or towed by a water tank truck by a hose or other means (32), and water can be supplied to the vehicle from the water tank tank to water the crops. it can. The vehicle (10) can be of a standard size such that the crop or tree to be processed fits inside the vehicle.

A hot water spray jet (34) for spraying hot water (12) onto the crop and its surroundings is provided on the inner surface inside the vehicle. The spray jet (34) can be of a known type that can pulsately spray hot water onto a crop or tree (14). Water (12) sprayed on crops and trees is drawn into the vehicle through a water intake (32) from a water tank truck mounted on the vehicle.
The water supplied from the truck enters a water supply tank (36) installed in the vehicle.

Before passing through the spray jet (34), the water is heated in the vehicle (10). In one embodiment, water flows from the intake through dual plastic coils (40), each installed in a microwave oven (38), and is heated to a temperature of about 150 ° C (FIGS. 3 and 4). reference). If there is a possibility of leakage, a microwave oven should not be used, but it is only necessary to seal around the coil. The coil (40)
It is made of plastic that allows microwaves to pass through it and enter the water inside. A reflective surface (42) must be provided on the microwave furnace wall (44) in the center of the plastic coil to increase furnace efficiency. Metals do not absorb heat, but paper, glass and most plastic materials allow microwaves to pass, allowing water to absorb the energy generated by the microwaves.

Instead of a microwave oven, by passing through a known heating piping system, grill or other type of grid,
Water can be heated. These piping systems, grills or grids can be heated by the exothermic paint applied to the surface of the metal grid. The exothermic paint can heat the grid to a high temperature by passing a small current through the paint. The exothermic paint can reach high temperatures when a small current passes through the paint or the substrate on which the paint is applied.
