Description

  The present invention relates to a biopesticide container and a method for preserving biopesticide using the same. More specifically, the present invention relates to a container for storing natural enemies (carp mites) that are used as biological pesticides for harmful insects (spider mites) that cause damage in the agricultural field and a method for storing the same.

  Reduce the use of pesticides such as chemically synthesized pesticides or acaricides in crop production (so-called reduced pesticides) or not, due to the growing demand for safe and safe food ingredients in recent years Efforts for (so-called pesticide-free) are being actively pursued. This is also attracting attention from both viewpoints because it is consistent with the demand for reducing environmental impact in crop production.

  On the other hand, biological insects and ticks that have a strong fertility and a short period of generation change, such as the spider mite, an agricultural pest, tend to acquire resistance to chemically synthesized pesticides (for example, non-patented Reference 1). Therefore, in agricultural production, it is becoming difficult to control using only chemically synthesized pesticides.

  As a solution to the above problems, in recent years, the introduction of biological pesticides to crop production sites has been increasing for the purpose of reducing the use of chemically synthesized pesticides and enhancing the control effect.

  However, it is often heard that the use of biological pesticides is difficult compared to conventional chemically synthesized pesticides. This is because (1) a stable biopesticide supply system has not been established or published, (2) it is difficult to maintain the quality of biopesticides, and it is recommended to be used immediately after arrival of biopesticides, (3 ) The reason is that it is difficult to decide when to release biopesticides to crop production sites.

  In order to solve the above problems, it is necessary to establish a biopesticide supply system that meets the supply and demand situation and to improve its use. Therefore, what is important is the establishment of technology for storage (defined as the period from production to transportation) without degrading quality. In addition, maintaining quality during transportation (defined as the period from production or storage until reaching the user's hand) is also an important issue. In addition, storage on the user side (defined as the period from reaching the user's hand until being released) is also important for adjusting the release time on the user side. So far, for example, the techniques described in Patent Documents 1 to 5 and Non-Patent Documents 1 and 2 below have been proposed as techniques related to containers for biopesticides used for at least one of storage, transport, storage and release of biopesticides. ing.

  However, in the above Patent Documents 1 to 5, the environmental adjustment in the biological pesticide container, particularly the adjustment of the air moisture environment, which is important for appropriately maintaining the body moisture of the biological agricultural chemical, is positive in the biological agricultural chemical container. Not done. In a conventional container, there is an example in which a moisture conditioning buffer material or a moisture absorbing material (such as sawdust) is put in the container. However, the water vapor pressure saturation in the container in this case is gradual and cannot be maintained at any desired value.

  The present invention has been made in order to solve the above-mentioned problems, and the present invention is a quality that is used in at least one of storage, transportation, and storage of biological pesticides and is also used for release. It is an object of the present invention to provide a biopesticide container that can be stored and a biopesticide storage method using the same.

  In addition, the biological pesticide storage method according to the second aspect of the present invention includes a water vapor supply container that contains water or an aqueous solution and supplies water vapor, an inner container having an inlet / outlet and a ventilation hole for the bio agricultural chemical, a water vapor supply container, and An openable / closable inlet / outlet for inserting / removing the inner container is used, and a water vapor supply container and an outer container for accommodating the inner container are used to store the biological pesticide in the inner container and supply water vapor from the water vapor supply container.

  As described above, according to the present invention, a biopesticide container capable of preserving quality and used for at least one of storage, transportation, and storage of a biopesticide, and also used for release, and the same are used. A method for preserving biological pesticides can be provided.

It is the schematic of the container for biopesticides which concerns on embodiment. It is the schematic of another example of the container for biopesticides which concerns on embodiment.

  Hereinafter, a biopesticide container (hereinafter referred to as “the present container”) according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different forms, and is not limited to the ranges exemplified in the following embodiments and examples.

  FIG. 1 is a diagram showing an outline of the container 1. As shown in the figure, the container 1 includes a water vapor supply container 2 that contains an aqueous solution 21 and supplies water vapor, an inner container 3 having an inlet / outlet 32 and a ventilation hole 33 for a biopesticide 31, a water vapor supply container 2 and contents. The container 3 has an openable / closable inlet / outlet 41 for taking in and out the vessel 3, and an outer container 4 for housing the water vapor supply container 2 and the inner container 3.

  In the present embodiment, the water vapor supply container 2 is for supplying water vapor to the outer container 4, more specifically, to the biological pesticide 31, and can store and hold water or an aqueous solution therein. Is. The steam supply container 2 is not limited as long as it has the above function. For example, it is preferable that the steam supply container 2 is a container having a bottom member and a side wall member that covers the periphery of the bottom member and having an open top. It is. In this case, it is also preferable to provide a lid member that is disposed on the side wall member and covers the opened portion, and the lid member is detachable as necessary. Furthermore, it is good also as a structure which provides a water vapor | steam from this window, providing a window in a part of side wall member or a cover member, while providing the cover member. In this case, the material of the water vapor supply container 2 is not limited as long as it can stably hold water or an aqueous solution, but, for example, glass, plastic, metal, or the like can be employed.

  In the present embodiment, it is also preferable to employ a gas-liquid separation membrane made of a moisture-permeable waterproof member that allows gas to pass but does not allow liquid to pass through at least part of the material of the water vapor supply container 2. By adopting a gas-liquid separation membrane made of a moisture-permeable waterproof member, for example, in the above-described example, the lid member covering the opened portion disposed on the side wall member is used for the gas-liquid separation made of the moisture-permeable waterproof member. If it is made into a film | membrane, it will not be necessary to attach or detach as needed, and even if it always covers with a cover member, a function can be show | played. Further, a gas-liquid separation membrane of a moisture-permeable waterproof member may be employed, the water vapor supply container 2 may be formed into a bag shape, and water or an aqueous solution may be stored in the bag and then sealed. By doing so, there is an advantage that the risk of spilling water or an aqueous solution from the water vapor supply container 2 due to vibration or the like when carrying the container is remarkably reduced. This example is shown in FIG. FIG. 2 shows an example in which not only the water vapor supply container 2 but also the inner container 3 and the outer container 4 have a bag shape. In the example of FIG. 2, a chuck is formed at the opening of each container, and the contents can be sealed, while the water vapor supply container 2 is provided with a moisture-permeable waterproof member gas-liquid separation membrane. It has been.

  The aqueous solution held and stored in the water vapor supply container 2 is not limited, but preferably contains a salt in water, and more preferably is a saturated salt aqueous solution. By containing the salt, there is an advantage that the water vapor pressure in the outer container 1 can be kept constant and the water vapor can be supplied into the outer container within a stable range for a long time. Further, the salt used in this case is not limited as long as the above function can be realized, but a lithium salt, a sodium salt, a magnesium salt, a potassium salt, and the like that are easily soluble in water. More specifically, for example, lithium bromide, lithium chloride, magnesium chloride, potassium carbonate, sodium bromide, sodium iodide, sodium chloride, potassium chloride and the like are preferable.

  Note that the water vapor pressure saturation in the outer container 4 (difference between the saturated water vapor pressure and the actual water vapor pressure) is the type and concentration of the salt contained in the water or aqueous solution to be added to the water vapor supply container 2 and the ambient temperature of the outer container 4. Determined by. The water vapor pressure saturation when only water is added to the water vapor supply container 2 is 0 kPa when the outer container 4 is not ventilated at all. On the other hand, when the saturated salt aqueous solution is put into the water vapor supply container 2, the water vapor pressure saturation is obtained from the saturated water vapor pressure and the relative humidity shown in, for example, Japan Industrial Standards Committee, “Hygrometer-Test Method JIS B7920”. It is done.

  Although illustration is omitted, in the case where a plurality of water vapor supply containers 2 are installed, there is an advantage that the water vapor pressure saturation in the outer container 4 can be adjusted to a desired value by a combination of water and saturated salt aqueous solution put into the water vapor supply container 2. is there.

  In the present embodiment, the inner container 3 can store the biopesticide 31 and has the entrance / exit 32 and the ventilation hole 33 for the biopesticide 31 as described above. The inner container 3 is not limited as long as it stably holds and stores the biopesticide 31 and does not unnecessarily release the biopesticide, but is disposed so as to cover the bottom member and the periphery of the bottom member. It is preferable to have a side wall member and a lid member disposed on the side wall member so as to face the bottom member. In addition, the entrance / exit 32 of the biological pesticide 31 may be formed by opening and closing the lid member as required, and making it detachable. Although the material of the inner container 3 is not limited, for example, glass, plastic, metal or the like can be used, and the material is not particularly limited.

  Moreover, the entrance / exit 32 of the biopesticides 31 is formed in the inner container 3 in this embodiment as mentioned above. The entrance / exit 32 of the biological pesticide 31 may be realized by attaching and detaching the lid member described above, but it is also possible to make a hole in a part of the side wall or the lid member to make the entrance / exit. In the case of a window, it is sufficient if the size is large enough to allow the biological pesticide 31 to pass through. For example, a hole having a diameter of 0.5 mm or more may be provided. In the present embodiment, it is preferable that the entrance / exit 32 of the biological pesticide 31 in the inner container 3 can be opened and closed as necessary. By having such a configuration, during the storage, transportation and storage period, the entrance / exit 32 is closed to prevent the escape of the biopesticides 31, while when the biopesticides are to be sprayed, the entrance / exit 32 is opened to open a desired position. It becomes possible to spray biological pesticides.

  Moreover, the ventilation hole 33 is formed in the inner container 3 in this embodiment as mentioned above. By providing the ventilation hole 33, it is possible to prevent the biological pesticide 31 housed therein from being killed due to lack of moisture, while the inner container 3 can be used even when condensed water is generated in the outer container. It is possible to prevent the intrusion of condensed water into the inside, and to prevent quality degradation due to the contact of the biological pesticide with the condensed water. About the ventilation hole 33, it is preferable to make a ventilation hole 33 by making a hole in a part of the side wall or the lid member or the like so that moisture can be supplied to the biological pesticide at all times. The size of the window is not limited as long as it can prevent the escape of the biopesticide 31 while allowing the gas to permeate. For example, the window has a space where the biopesticide 31 cannot pass through. A film made of a member made of a filter material or the like is preferable. In this case, although not limited, for example, when the member film has a mesh shape, the maximum value of the gap is preferably less than 0.3 mm, more preferably 0.1 mm or less. By setting it as this range, while escape of a biopesticidal agent is prevented, gas can fully permeate | transmit.

  The inner container 3 in the present embodiment is as described above, but is not limited. For example, a film made of a member having a function as a ventilation hole may be arranged in a glass container having an opening. Well, it can be carried in this state during normal carrying, and when spraying biological pesticides, it can be made to function as an entrance / exit and a ventilation hole by removing the membrane member of this ventilation hole.

  Furthermore, in addition to the above, the inner container 3 in the present embodiment is formed into a bag shape using, for example, a film-like plastic such as vinyl, provided with a ventilation hole at least in part, and a zipper portion (chuck) that can be sealed in the bag. By providing, it can also be set as the inner container which has a ventilation hole and an entrance / exit. An example of this is shown in FIG. In addition, it is unnecessary if the material of the inner container 2 is a material that is hard enough to maintain a space where the biopesticides can survive, but when the inner container 3 is a flexible bag-like one It is necessary to maintain a space for the biopesticide to survive so that the biopesticide will not be crushed or damaged. Specifically, it is preferable to maintain a space by putting a cushioning material or the like in the inner container 3. In any case, compared with the method using a large amount of sawdust and the like, the container for biological pesticide can be made compact.

  In the case where the inner container 3 and the outer container 4 of the biopesticide container are made of a flexible material, the outer container 4 is not simply used as the entrance / exit shown in FIG. The doorway may be opened and closed by opening it.

  Moreover, you may arrange | position the ventilation hole 33 and the entrance / exit 32 in this embodiment so that it may overlap. For example, by arranging the ventilation hole 33 in the upper part of the entrance / exit 32 (outside of the inner container 3), it is possible to normally prevent the escape of biological pesticides by covering the entrance / exit, as in the above example. The biopesticide can be stably held and carried because it can be maintained, but when spraying the biopesticide, it can function as an entrance and a vent by removing the membrane of this vent hole It becomes like this.

  In the present embodiment, the biological pesticide is a living organism useful for controlling pests and the like that have harmful effects on agricultural products, and can be variously employed as long as it is a natural enemy of pests, but is not limited thereto. For example, at least one stage of development of eggs, larvae, pupae and adults, and mites of at least one stage of development of eggs, larvae, first nymphs, second nymphs and adults It can be used, and more preferably, it is a dust mite. In this case, the pest is particularly effective when it is a spider mite. In addition, when putting biopesticides in an inner container, it is preferable to put support materials, such as a plant.

  In this embodiment, the outer container 4 can accommodate the water vapor supply container 2 and the inner container 3. Although not limited to this, it is preferable that the outer container 4 also has a bottom member and a side wall member arranged around the bottom member, and if necessary, on the upper part of the side wall member. It is preferable to have a lid member that can be opened and closed. By doing in this way, the said water supply container and an inner container can be accommodated and hold | maintained stably. Further, the material of the outer container 4 is not limited as long as it has the above function, but for example, glass, plastic, metal, etc. can be adopted. In order to reduce the space related to storage, transportation, and storage, it is desirable to make the inner container 2 compact so that the inner container 2 occupies the space other than the space required for adjusting the water vapor pressure saturation.

  Further, the water vapor pressure saturation inside the outer container 4 is affected by the water vapor pressure saturation outside the outer container 4 due to clearance ventilation of the outer container 4. When the water vapor pressure saturation outside the outer container 4 is lower than the water vapor pressure saturation inside the outer container 4, the amount of water or a saturated salt aqueous solution in the water vapor supply container 3 decreases. Therefore, in order to appropriately maintain the water vapor pressure saturation in the outer container 4 without touching the inner container 3 during storage, transportation or storage, a packing is installed at the inlet / outlet 41 of the outer container 4. It is preferable to suppress clearance ventilation of the outer container 4 by taking measures.

  In addition to the above, the outer container 4 in the present embodiment is formed into a bag shape using, for example, a film-like plastic such as vinyl, provided with a ventilation hole in at least a part, and a zipper portion (chuck) that can be sealed in the bag. By providing, it can also be set as the outer container which has a ventilation hole and an entrance / exit.

  As mentioned above, in this container, it becomes possible to always supply water vapor by providing the water vapor supply container, and this water vapor can be supplied to the biopesticides via the ventilation holes of the inner container. As a result, the preservation state of the biopesticide can be kept good. On the other hand, the inner container is provided with a ventilation hole and a biological pesticide entrance and exit, and the entrance and exit can be opened and closed as necessary. On the other hand, the escape of biological pesticides can be prevented. And by storing the inner container and water vapor supply container together in the outer container, it can be carried and can be sprayed with biological pesticides where necessary, specifically the contents from the outer container The container can be taken out and placed in any place. As a result, this container is a biopesticide container that can be used for storage, transportation, and storage of biological pesticides and that can be used for free storage.

  In addition, by using this container, a biopesticide can be preserve | saved and it becomes a useful preservation method of a biopesticide. Specifically, it has a water vapor supply container for storing an aqueous solution and supplying water vapor, an inner container having a biological pesticide inlet / outlet and a ventilation hole, a water vapor supply container and an openable / closable inlet / outlet for taking in and out the inner container. In addition, a biopesticide storage method is provided in which a water vapor supply container and an outer container containing the inner container are used, the biopesticide is stored in the inner container, and water vapor is supplied from the water vapor supply container. As a result, as described above, the biopesticide preservation method can be used in at least one of storage, transportation, and storage of biopesticides and can also be used for release. After storage, take out the inner container 3 from the outer container 4, place it in a place where there is or is predicted to be a pest targeting the inner container 3, and open the entrance / exit of the inner container 3 to remove the biological pesticide. Can be released. When the entrance / exit of the inner container 2 is opened and installed in a place where the target pests are or are expected to be present, the biological pesticides move out of the inner container 3 in search of pests that serve as food. Biological pesticides move spontaneously. By spontaneous movement of the biopesticide, the biopesticide 1 can be released without causing deterioration in quality due to damage of the biopesticide 1 or the like.

  In the present embodiment, the water vapor supply container, the inner container, and the outer container are disposed so as to face the bottom member, the side wall member disposed so as to cover the periphery of the bottom member, and the bottom member on the side wall member. However, it is also a preferable example that at least one of the water vapor supply container, the inner container, and the outer container is a bag-like container. By making it into a bag shape, there is an advantage that it is easy to carry with a small volume. In the case of a bag-like container, it is preferable that the opening has a chuck for opening and closing, instead of the lid member. By doing so, it can be carried more easily and with a small volume.

  Hereinafter, the biological pesticide storage container according to the above embodiment was actually produced, and the effect was confirmed. This will be specifically described below.

(Experimental example 1)
(Materials and methods)
In this example, a polycarbonate container provided with a lid having a packing was used as the outer container 4 of the biopesticidal container. Moreover, the petri dish was used as the water vapor supply container 2 in the biopesticide container, and water or a NaCl saturated salt aqueous solution was placed in the water vapor supply container 2. The biopesticide storage container was placed in a glow chamber.

(Measurement and observation)
During storage, the temperature and relative humidity in the bio-pesticide container were measured, and the water vapor pressure saturation was calculated.

(Environment in containers for biological pesticides)
The temperature in the bio-pesticidal container is 5.1 ± 0.1 ° C. when water is added to the steam supply container 2, and 5.3 ± 0.2 ° C. when NaCl saturated salt aqueous solution is added to the steam supply container 2. Met. On the other hand, the temperature in the glow chamber containing the bioagrochemical container was 4.9 ± 0.5 ° C. This is presumably because the temperature variation in the biopesticide container is smaller than that outside the biopesticide container due to the heat capacity of the biopesticide container.

  The water vapor pressure difference in the bioagrochemical container was 0 kPa when water was added to the water vapor supply container 2 and 0.21 kPa when water was added to the water vapor supply container 2. On the other hand, the temperature in the glow chamber containing the bioagrochemical container was 0.25 ± 0.23 kPa. It was possible to stably produce different water vapor pressure saturations in the biopesticide container when water was added to the steam supply container 2 and when a saturated NaCl aqueous solution was added. Considering that the evaporation of water from the biological pesticide is negligible, the water vapor pressure saturation of the outer container 4 and the inner container 2 is considered to be the same value. Therefore, it was shown that the water vapor pressure difference of the inner container 2 can be adjusted by the type of water or the saturated salt 31 put in the water vapor supply container 2.

(Experimental example 2)
(Materials and methods)
In this experimental example, a polycarbonate container provided with a lid having the same packing as that of Experiment 1 was used as the outer container 4 of the biopesticidal container. In addition, the petri dish was used as the water vapor supply container 2 in the biological pesticide container, and water was put into the water vapor supply container 2. Furthermore, a polypropylene container equipped with a ventilation hole attached with a filter having a pore diameter of 0.3 μm was used as the inner container 3 of the biopesticidal container. Prior to the start of storage, adult male pesticides (Neoseiulus californicas (McGCregor)) female adults were placed as biological pesticides 1 in each of the plurality of inner containers 2. During storage, the biopesticide container was placed in a growth chamber set at a temperature of 5 ° C. During the storage period, adult male mosquitoes were not fed with food spider mite.

(Measurement and calculation)
After 28 and 56 days from the start of the experiment, the survival rate of female adult oyster mites contained in the inner container 2 was examined. In order to evaluate the quality of the surviving adult oyster mite, as a biopesticide 1, it was transferred to a laboratory at a temperature of 25 ° C. Therefore, we investigated the chemotaxis of spider mites and predation status of spider mites.

(result)
By controlling the energy consumption of adult females of the house spider mite during the storage period by placing the container for biological pesticides at a low temperature, and by suppressing the water loss of the adult female of the house spider mite by reducing the water vapor pressure saturation, The survival rate could be maintained at 100% after 28 days and 38% after 56 days.

  After the storage, when the inner container 2 housed in the outer container 1 was transferred onto a petri dish and observed, the adult male moss mite spontaneously moved out of the inner container 2. There was no difference in the chemotaxis of adult females of the house spider mite. In addition, when spider mites were given, the stored adult oyster mite was preyed.

  As a result, it was confirmed that the effects of the present invention are as described below.

  First, the biopesticide container of the present invention that is made compact allows the biopesticide to be stored, transported, or stored even under conditions where the space that can be used is limited.

  Moreover, in the biopesticide container of the present invention, the water vapor pressure saturation during the period during which the biopesticide is stored, transported or stored can be adjusted with a simple configuration. Conventionally, when creating a physical environment condition including a similar difference in water vapor pressure, a heavy and long physical environment adjusting device has been used, and it is also necessary to input energy. However, the present invention can easily create an environment suitable for storage, transportation or storage of biopesticides.

  Moreover, although there exists a prior art which adjusts the water vapor pressure saturation in the container for biological pesticides with a moisture retention adjusting material, a humidity control buffer material, or a moisture absorption material, it is difficult to adjust to any desired water vapor pressure saturation. However, according to the present invention, the truly desired water vapor pressure saturation is obtained by utilizing water or a saturated salt solution. Here, the truly desired water vapor pressure saturation is the difference between the water potential balanced with the water potential of the biological pesticide and the saturated water vapor pressure at the given temperature.

  Moreover, in the conventional container, there is a concern that the quality of the biopesticide may deteriorate due to condensation on the wall surface of the container in which the biopesticide is stored. However, in the present invention, it is rare that dew condensation occurs in the inner container even under conditions where the water vapor saturation in the biopesticide container is small. Therefore, the quality degradation of the biopesticide due to condensation hardly occurs. .

  In addition, even if the temperature outside the biopesticide container and the water vapor pressure difference fluctuate, the temperature inside the biopesticide container and the heat capacity of the materials constituting the biopesticide container and The variation in the water vapor pressure difference is smaller than the variation in the temperature outside the biopesticide container. When the storage, transportation, or storage temperature condition is at a low temperature or high temperature limit, the small fluctuation in temperature, which is one of the characteristics of the biopesticide container of the present invention, will cause a decrease in the quality of the biopesticide 1. It helps to prevent. In addition, stabilization of the water vapor pressure saturation can reduce the adverse effect of fluctuations in water loss of the biological pesticide 1, and therefore can reduce the quality deterioration of the biological pesticide 1 due to water loss.
