Description

  The present invention provides a protective cover for protecting a pest control agent suspended from a part of a plant to be protected from falling due to rain, exposure to agricultural chemicals, and food damage such as rats and slugs, and the preparation thereof Relates to methods and methods of use.

  At present, the mainstream of pest control for agricultural crops is control using chemical substances such as insecticides and fungicides. However, the control of pests with the aim of controlling the impact on other ecosystems is minimized. A means for specifically controlling only the worm is used. For example, an integrated pest management (IPM) method using predatory natural enemy organisms (for example, Patent Documents 6 and 7) and a communication disruptor using a pest sex pheromone (Patent Documents 4 and 5) can be exemplified.

  In the IPM method, natural enemies that have the ability to prey before the occurrence of pests are pre-established and propagated on the crops to maintain the pests at a low density. It is necessary to proliferate. For this reason, products that contain bran, yeast, and prey organisms in bottles along with natural enemy organisms, and pack preparations that contain these ingredients in bags made of non-woven fabric and are equipped with paper suspension means are on sale. Has been. The pack preparation is advantageous in that it can be installed while maintaining the growth environment. However, the conventional pack preparation has a problem that the suspended part is destroyed by the rain and the pack preparation falls, and it is directly exposed to the sprayed pesticide. In addition, there were cases where they were damaged by rats and slugs.

  In order to maintain natural enemies in the field of crop cultivation for a long time even if pests are low, there is a technology that puts natural enemy organisms directly or pack preparations containing them into a breeding device that secures food and egg-laying locations. It has been devised (Patent Documents 1, 2, and 3). Such a device can also be an effective means in protecting the pack formulation from falling due to rain, direct exposure to pesticides, and damage caused by rats, slugs and the like.

However, these devices actually do not necessarily have an advantage over the pack preparation in terms of the growth of natural enemy organisms and pest control effects, but the economic burden is large, The work burden associated with assembling the equipment at the agricultural site is not small.
Accordingly, there is a need for a technique that is less economically burdensome and allows crop producers to easily install pest control agents.

For example, preferred examples include a combination of a pack preparation containing a predatory organism and a communication disruptor containing a pest sex pheromone, and a combination of a pack preparation containing a predatory natural enemy organism and a repellent against an organism that causes damage to the pack preparation. Can be mentioned.

  As shown in FIGS. 4 and 4, the preparation 2 protected by the protective cover according to the present invention has a suspension part 3, and is suspended from a plant body to be protected from pests or a part of a structure in the vicinity thereof. It is used. The suspension part 3 can be made of various materials, but is usually made of cardboard, plastic or the like in order to reduce manufacturing costs. In the case where the cardboard is made of cardboard, the strength of the cardboard decreases when exposed to rain, and the preparation absorbs water and becomes heavy, so that the weight cannot be supported and the preparation falls. Even in the case of plastic, the strength of the adhesive portion between the preparation and the suspension is reduced, the preparation absorbs water and becomes heavy, and the weight cannot be supported and the preparation falls.

The shape or structure of the suspension part 3 is not particularly limited as long as it is a shape or structure that allows the preparation to be suspended from an object, and may take various shapes and structures. One typical structure is a hook shape as shown in FIG. Here, the hook shape means a shape in which the tip is bent and can be suspended at that portion, and should be understood as a term including various shapes. Another typical structure includes a through-hole 5 for passing a suspended part of the object as shown in FIG. 4 and a suspended object from the outer edge of the suspended part 3 to the through-hole 5. It has a structure having a guide portion 6 for guiding a part. A typical example of the guide unit 6 is a cut 7.
Moreover, the size of the suspension part can be various sizes, and the suspension part 3 having a width narrower than the width of the pack or the control agent part 4 as shown in FIGS. 4 and 4 may be used. It is good also as a suspension part of the width | variety substantially the same as the width | variety of the pack or the control agent part 4 like the insect pest control formulation shown in FIG. In the latter case, the bonding area between the suspension part and the pack or the control agent part 4 is increased, so that stronger bonding is possible. However, even in this case, the resistance to rain or the like is not sufficient without the protective cover of the present invention. .

  Examples of pack preparations containing such predatory natural enemies include pack preparations sold under the trade names “Swarsky Plus” and “Spiral Plus” by Arista Life Sciences, Inc. Can include pack preparations sold under the trade names “swirskii breeding system” and “amblyseius breeding system”. These pack preparations include predatory natural enemy organisms such as turnip mites, yeast, bait mites, and bran in a pack made of non-woven fabric of a predetermined size, and the pack is provided with holes through which natural enemy organisms are released. In addition, the pack is provided with a hanging portion made of cardboard and having a predetermined size. This suspension part is provided with a through hole for passing the suspended part of the object and a notch that leads from the outer edge of the suspended part to the through hole. Through this notch, the suspended part of the object is a through hole. Led to.

As shown in FIG. 2A, the protective cover of the present invention prevents the insect pest control preparation (2) from being exposed to rain and pesticides, and protects it from food damage such as slugs. The pest control preparation (2) having the above can be covered, and has a shape and structure that can be suspended together with the pest control preparation (2).
Therefore, the protective cover of the present invention needs to have a size that can cover the entire preparation (2) including at least the suspension (3). Moreover, it has a structure or a shape corresponding to the suspension part (3) of a pest control preparation (2), and needs to be able to hang on a target object with a preparation (2).

As the shape or structure of the suspension part (3) of the pest control preparation (2), very various shapes and structures can be assumed, but the shape or structure of the protective cover (1) of the present invention is basically The pest control preparation (2) may be suspended on the object together with the preparation (2) in accordance with the shape or structure of the suspension (3). For example, as shown in FIG. 4, the suspension part (3) of the pest control preparation (2) penetrates from the through-hole (5) for passing the suspended part of the object and the outer edge of the suspension part (3). When it has the guide part (6) which guides the suspended part of the object to the hole (5), as shown in FIG. 2A, the protective cover (1) is the suspension part (3) of the pest control preparation (2). It can be set as the structure or shape which has a through-hole (10) and a guide part (11) in the position corresponding to the through-hole (5) and guide part (6) of this, respectively. As shown in FIG. 5, when the suspension part (3 ′) of the pest control preparation (2) is hook-shaped, the protective cover (1) is used as the suspension part of the pest control preparation (2) as shown in FIG. 2B. There is a through hole (10) corresponding to the position (8) through which the suspended part of the object is passed in (3), and the through hole is formed from the outer edge of the protective cover corresponding to the hook-shaped opening position (9). It can be set as the structure or shape which has the guide part (11) which guides the suspended part of a target object to (10).
On the other hand, for example, as shown in FIG. 3A, the guide part (11) of the protective cover (1) is not necessarily in a position corresponding to the guide part (6) provided in the suspension part (3) of the pest control preparation (2). It is not necessary to provide it. In the example shown in FIG. 2C, the notch (12) extends downward from the through hole (10), changes the direction to the left near the center, and reaches the left end of the cover, as shown in FIG. 3B. A part (31) of the cover (1) can be lifted by the notch (12), and the object is suspended through the guide (6) provided in the suspension (3) of the pest control preparation (2). The part 32 can be led to the through holes (5, 10). For example, in the case of a pack preparation containing natural enemy organisms, a hole is usually provided in the pack so that the natural enemy organisms can be released to the external environment. It becomes easy for water to enter into the pack through. In such a case, it is preferable that the position of the hole provided in the pack preparation and the position of the guide portion of the protective cover do not overlap. As a result, as shown in FIGS. The guide part 11 may be provided in a position not corresponding to the guide part 6 provided in the suspension part 3 of the pest control preparation 2.
The through-holes 5 and 10 for passing the suspended part of the object may be, for example, holes smaller than the diameter of the suspended part, and may have a structure having a plurality of radial cuts. A typical example of the guide portion 11 is a cut leading from the outer edge of the protective cover 1 to the through hole 10.

  There is no restriction | limiting in particular about the base material which comprises the protective cover of this invention, It can comprise with various materials. However, a material having an acceptable range of material costs, a waterproof property that can protect the pack preparation from rainfall and spraying of agricultural chemicals, and a strength or characteristic that can protect against food damage such as rats and slugs is preferable. A material having flexibility is preferred. Examples of such a base material include a sheet-like material in which at least one synthetic resin selected from polyethylene film, polyester film, polyurethane film, and the like, a metal foil, a nonwoven fabric, and the like are singly or laminated.

  In addition, materials having various shapes or structures can be selected as the base material constituting the protective cover of the present invention. For example, a single sheet-like material, a cylindrical material, a bag-like material, or the like can be used. In addition, these materials constituting the protective cover usually have a thickness of 0.01 mm to 2.5 mm, and preferably have a thickness of 0.1 mm to 0.5 mm. For example, a high-density polyethylene non-woven fabric having a thickness of 0.13 to 0.17 mm, which is commercially available as a product name Tyvek sheet, can be used as a suitable base material constituting the protective cover of the present invention.

  As can be understood from the above description, the protective cover of the present invention can be made very easily. For example, as shown in FIGS. 1 and 6, a sheet-like base material 17 having a size capable of finally covering the entire pest control preparation is prepared, and the suspension part of the pest control preparation as described above is prepared. A shape or structure corresponding to is provided at a predetermined position, and it is created by folding it in the center. In the example of FIGS. 1 and 6, the through hole 10 and the notch 11 are provided at positions corresponding to the through hole and the guide part of the suspension part of the pest control preparation, respectively, but the shape or structure of the suspension part of the pest control preparation is provided. Various shapes or structures may be used accordingly. In this example, the outer shape of the protective cover 1 is rectangular, but it can be appropriately formed into a desired shape using scissors or the like according to the shape of the suspension. Further, in the protective cover 1 of this example, an end portion 13 that is closed at a position corresponding to a fold is formed, but when the preparation is suspended with the preparation covered with the protective cover, the end portion 13 is moved upward. It is preferable to position. By doing in this way, the tolerance with respect to rainfall can be improved effectively. In addition, the fact that the left and right ends (15, 15 ') and the lower ends (13, 13') are open makes it very easy to operate when installing and hanging the pack preparation. After installing the pack preparation, the lower end (13) of the protective cover can be stopped with a staple or the like to eliminate the gap between the protective cover and the preparation, thereby enhancing the protective effect. Alternatively, as shown in FIG. 8, the length is set such that one lower end (13) protrudes from the other lower end (13 ′), and the protruding portion (19) is folded after the pack preparation is installed. The lower end may be closed, or as shown in FIG. 9, a slit-like insertion portion (20) is formed by cutting one lower end (13), and a protective cover is attached to the other lower end (13 ′). In some cases, the insertion part (20) is provided with a notch 23 into which the insertion part (20) can be inserted. The lower end (13, 13 ′) may be closed, and as shown in FIG. 10, the insertion portion (22) which can be inserted into and engaged with both lower ends (13, 13 ′) of the protective cover. , 23), and after the pack preparation is installed, the insertion portion (22 23) plugged into each other by engaging the, it may close the lower end (13, 13 ').

  Moreover, as shown in FIG. 11, when the protective cover 1 is produced with a cylindrical base material (18), it is basically the same, and the shape or structure of the suspension part of the pest control preparation is placed at a predetermined position. A corresponding shape or structure may be provided to allow suspension with the formulation. Also in the case of a protective cover made of a cylindrical base material, the preparation can be moved to the center so as to slide from the left and right openings.

  The protective cover of the present invention may contain other control agents, or may be used with other control preparations attached. As an example of the former, for example, a protective cover which is made of a base material containing a communication confusing agent such as a sex pheromone substance or a repellent, and protects a pack preparation containing natural enemy insects can be cited. Include attaching other preparations containing communication disrupters and repellents to protective covers that protect pack preparations containing natural enemy insects. Particularly in the latter case, for example, as shown in FIG. 12, when attaching another preparation 16 containing a communication disruptor or a repellent, it is installed at the open end (for example, the lower end 13) of the protective cover, The utilization aspect which eliminates the clearance gap between 1 and the formulation of protection object can be mentioned. As a more specific example, a flexible tape or tube (16, usually with adhesive means) is releasably retained to protect the flexible tape or tube 16 from release. A part of the cover 2 is attached to the open end (for example, the lower end 13) of the cover, and after the preparation 2 to be protected is placed at a predetermined position, the protruded part of the tape or tube 16 is folded to open the open end 13 of the protective cover 1. Can be closed.

  Examples of the substance capable of holding the communication confusion agent and the repellent include polymer polymers such as polyethylene and polypropylene, and the tape material is preferably a flexible material having flexibility such as rubber and flexible metal. Moreover, you may utilize the polyethylene-made tubes containing the communication disturbance agent marketed by brand names, such as a confuser R, for example.

  In addition, examples of the communication confusion agent include those that target organisms that cause harm to the same crop, although they are different from pests controlled by predatory natural enemy organisms. For example, an example of combining a control agent whose target for control by predatory natural enemies is a dust mite with a communication confusion agent targeting lepidopteran pests and the like can be given. Moreover, as a repellent, the repellent with respect to the organism | raw_food which brings about damage to a pack formulation containing a predatory natural enemy organism can be mentioned as a preferable example.

  EXAMPLES Hereinafter, although an Example demonstrates this invention more concretely, the technical scope of this invention is not limited to these illustrations.

Folded in the middle so as to be equal to 110 mm in length, and cut out so that a circular through hole 10 having a diameter of 15 mm was formed at a position 10 mm from the fold and 29.5 mm from the left and right ends. Further, from the lower part of the through hole 10 to the left end of the base material, a notch 11 is inserted at a position corresponding to the incision of the suspended part of the pack preparation so that a part of the subject to be suspended can be guided to the through hole 10 through the notch. . In the evaluation test described later, the through hole and the cut of the protective cover are matched with the through hole and the cut of the suspension of the pack preparation, and the protective cover is attached to the pack preparation so that the entire pack preparation including the suspension is covered. .
In addition, the protective cover of this example shows the shape and structure according to the pack preparations currently on the market, and for other sizes, shapes, and structures, naturally the protective cover is prepared accordingly. It goes without saying that it is done.

2. Evaluation of protective cover The performance of the protective cover prepared in the example was evaluated.

2-1. Effect on pest control effect A pack preparation (commercial product name: Swarsky Plus) containing a Swarsky burdock mite is placed in a plastic cup with a protective cover prepared in Example 1, placed at 25 ° C. and a humidity of 80 Left under ~ 90% condition. The number of Swarsky cabriolet mites released from the pack formulation at 7-day intervals was counted.

  There was no significant difference in the release of Kabritani from the pack formulation with or without a protective cover.

2-2. Rain resistance evaluation A pack preparation containing Swarsky Kaburani mites (commercial product name: Swarsky Plus) is hung on a branch of eggplant cultivated in an open field in the rain, and one side is attached with the protective cover created in Example 1 Hanging. The number of suspended pack preparations was 15 packs per 30 m ^{2 of the} farm field.

  The protection cover clearly prevented the pack preparation from falling in the rain.

2-3. Evaluation of protective effects against food damage Slugs collected in a field (Tsukuba City, Ibaraki Prefecture) in a plastic cup containing a pack formulation containing predatory mite (commercial product name: Spical Plus) and a pack formulation with a protective cover Five (a kind of Asteraceae) were put and left under conditions of 25 ° C. and humidity of 80 to 90%. After 10 days, the damage area on the surface of the pack preparation was calculated, and the presence or absence of damage suppression effect was confirmed.

  It was found that the damage caused by slugs was clearly suppressed by attaching the protective cover.

2-4. Control effect of thrips in open-season eggplants cultivated in summer / autumn In the open-field eggplant field cultivated in summer / autumn, control was carried out using a pack preparation containing Swarzka cabbage mites for the control of thrips. This test was conducted in an open field including the rainy season from the beginning of June to the end of July, and there were a total of 20 days of rain throughout the test period (total 61 days). The pack preparation used was sold by Arista Life Science Co., Ltd., equivalent to 200 packs per 10a, and in Test Zone 1, a protective cover was attached to the pack preparation. On the other hand, in the test group 2, the pack preparation was installed as it was without attaching a cover. As a control, an untreated area (unreleased area) was provided. One test section was 20 m ² and 3 repetitions were made.

  All pack preparations without protective covers installed during the test period had fallen from the attached eggplant branches at the end of the test period, but all pack preparations suspended with protective covers attached were suspended at the same time. It was as it was. Generally, in the summer and autumn cultivation, the eggplant is planted from May to June and continues to be harvested until October. Therefore, when one month has passed since planting, it is the rainy season in each region except Hokkaido. For this reason, chemical pesticides cannot be sprayed, the number of pests increases gradually, and the explosion increases with the end of the rainy season. The application of the Swarsky Kaburani mite formulation for the control of thrips in open-air eggplants is very effective to make up for the weaknesses of these chemical pesticides, but it also improves the sustainability by attaching a protective cover, and is always a natural enemy Kaburidani Can provide a base from which they are released.

2-5. Evaluation of the effect of combined use with a communication disruptor In the test area, after covering the pack preparation (commercial product name: Spikal Plus) containing Miyakocabari mite with the protective cover prepared in Example 1, under the protective cover, Horizontally installs a Confuser R (manufactured by Kyori Aguri Co., Ltd.) that retains in a polyethylene tube a communication disruptor that has been registered as an agrochemical against apple cockroaches, midarekamonmonki, applemonhamaki, peach shingaiga, and pear cinnamon moth. The both ends were folded and the lower end of the protective cover was closed. In the control group, the pack preparation was covered with a protective cover, and then used without attaching Confuser R (manufactured by Kyori Agri Co., Ltd.). In the pear field (Iizaka City, Fukushima Prefecture), 100 packs per 10a were suspended in both the test zone and the control zone.
As the effect of Confuser R, a pheromone trap was applied one month later to compare the number of adult peach moths, and the effect of the pack preparation was compared with the number of spider mites that lived on pear leaves one month later.

  When a protective cover was attached to a pack preparation containing the spider mite predatory natural spider mite, and for the sake of convenience, a confectioner R was attached, and adult peach sink moths were not captured and the density of spider mites could be kept low. . On the other hand, although the spider mite density was suppressed with the protective cover alone, no effect on the peach moth was observed. The density of spider mites was lower in the pack preparation use area without a protective cover than in the case of no treatment, but there were some drops due to rain, and the density of spider mites was higher than that of the waterproof cover use area.

As described above, the protective cover of the present invention prevents the pest control preparation from falling due to rain, can protect the pack preparation from food damage such as rats and slugs, and can continuously exert the control effect.
It is easy to use together with other types of pest control agents, or different types of control agents such as communication disrupters and repellents. provide.
