Description
本発明は、植物に付着した各種の害虫を植物から離脱させて駆除する方法に関する。 The present invention relates to a method for removing various pests adhering to a plant and removing them from the plant.
本発明者は、さきに、植物に付着したアブラ虫、アオ虫、ヨトウ虫、コナガ虫等の気管呼吸型害虫の殺虫駆除方法として、害虫を駆除すべき植物の細胞液の濃度よりもわずか高い濃度から濃度零の間に調整された浸漬用水溶液を準備し、該水溶液中に害虫の付着した植物を、該害虫の死滅に要する時間浸漬することから構成される植物の害虫殺虫駆除方法を提案した。 The present inventor, as an insecticide control method for trachea respiratory pests such as Brassicaa, Blue insects, Coleoptera, Rana, etc. attached to the plant, is slightly higher than the concentration of the cell fluid of the plant to be controlled Proposing a pest control method for plant pests, comprising preparing an aqueous solution for immersion adjusted between concentration and zero, and immersing the plant with pests in the aqueous solution for the time required to kill the pests did.
しかし、上記の従来方法では、害虫を死滅（窒息死）させるに必要な浸漬時間に、アブラ虫で３〜４時間、アオ虫で１〜２時間と長時間を要する欠点があり、しかも水溶液の濃度調整を誤れば長時間の浸漬により植物に重大なダメージを与える危険もあり、これを避けるために水溶液の濃度調整を慎重に行わなければならない不便もあった。
本発明は、従来方法の浸漬に長時間を要する欠点を改善すると共に植物の安全を保つことができる害虫駆除方法を提供することを課題とする。 It is an object of the present invention to provide a method for controlling pests that can improve the drawbacks that require a long time for immersion in the conventional method and can keep the plant safe.
そこで、本発明は、
害虫を処理すべき植物の細胞液の濃度より約０．１〜０．３Ｍ（モル濃度）高い濃度から濃度零の間の濃度に調整した浸漬用水溶液を準備し、
害虫の付着した上記植物を上記水溶液中に約３〜２０分浸漬して該水溶液から引上げ、次に上記短時間浸漬を約１０〜６０分間隔をあけて２〜６回繰返し、この繰返し浸漬を毎日１〜３度行い、それにより上記植物に付着した害虫を植物から水溶液中に離脱させ、
上記離脱して上記水溶液中に沈下した害虫を水溶液の濾過装置により、及び水溶液面に浮かぶ害虫を網によりそれぞれ回収して処分する、
植物の害虫離脱駆除方法を提案する。
Therefore, the present invention provides
Preparing an aqueous solution for dipping adjusted to a concentration between about 0.1 to 0.3 M (molar concentration) higher than the concentration of the cell fluid of the plant to be treated with pests and a concentration between zero,
The plant deposited pests pulling from about 3 to 20 minutes immersed in the aqueous solution in the aqueous solution, then repeated 2-6 times at an approximately 10 to 60 minute intervals the short immersion, the repeated immersion 1 to 3 times a day, thereby causing the pests attached to the plant to leave the plant in an aqueous solution,
The pests that have detached and settled in the aqueous solution are collected and disposed of by a filtration device for the aqueous solution, and the pests floating on the aqueous solution surface are collected by a net .
We propose a method for exterminating plant pests.
本発明の植物の害虫離脱駆除方法によれば、害虫の付着した植物を、該害虫を植物から離脱させるために短時間浸漬するのであるから、従来方法の害虫を窒息死させるための長時間浸漬と比較して、浸漬時間を大幅に短縮することができると共に、植物の安全を保つことができるのである。 According to the plant pest removal control method of the present invention, the plant to which the pest is attached is immersed for a short time in order to release the pest from the plant. Compared to the above, the dipping time can be greatly shortened and the safety of the plant can be maintained.
本願発明における上記「約３〜２０分浸漬」に関して、まず植物の浸漬時の安全について検討する。
一般に、植物を水溶液中に浸漬したとき、植物生理学上は、浸漬中植物の細胞が生き続けていさえすれば、浸漬後水溶液から取り出した植物は何の後遺症も残さず健全に成長する。その場合浸漬中の植物細胞の生死を左右するものは、植物の細胞液と水溶液との間の浸透圧の高低、換言すれば浸透圧を決める濃度の高低であることが知られている。そこで、両者を対比して検討してみる。なお、植物の細胞液の浸透圧は、植物の種類によって異なるが、常温で５〜１０atm、濃度は０．２〜０．８Ｍ（モル濃度）である。
Regarding the above-mentioned “ about 3 to 20 minutes immersion” in the present invention, first, the safety at the time of immersion of the plant is examined.
In general, when a plant is immersed in an aqueous solution, in terms of plant physiology, as long as the cells of the plant remain alive during the immersion, the plant taken out from the aqueous solution after the immersion grows healthy without leaving any sequelae. In this case, it is known that what determines the viability of plant cells during immersion is the level of the osmotic pressure between the plant cell solution and the aqueous solution, in other words, the level of the concentration that determines the osmotic pressure. Therefore, we will consider both of them. In addition, although the osmotic pressure of the cell fluid of a plant changes with kinds of plant, it is 5-10 atm and the density | concentration are 0.2-0.8M (molar concentration) at normal temperature.
（１）植物を該植物細胞液と等濃度の水溶液に浸漬した場合。
植物細胞への水の出入りはなく、細胞は形を維持したまま生存し続ける。
(1) When a plant is immersed in an aqueous solution having the same concentration as the plant cell solution.
There is no water in and out of plant cells, and the cells continue to survive while maintaining their shape.
（２）植物を該細胞液より低濃度の水溶液に浸漬した場合。
細胞は半透性の細胞膜を通して外側の水溶液から水を吸収して原形質を膨らませていく。ところで、植物細胞は、上記細胞膜の外側に全透性の弾性組織からなる細胞壁を有するため、上記の膨らんだ原形質が上記細胞壁に押し広げようとする膨圧を及ぼし、その反作用として細胞壁から元に戻ろうとする壁圧を原形質に受ける。細胞が膨らむにつれ細胞内の濃度は低下し、その浸透圧は減って行くと共に、上記膨圧が高まっていき、それと大きさの等しい壁圧が細胞内の浸透圧と等しくなったとき細胞の外側からの吸水を自動的に停止し、そして膨らんだ緊張状態で生存し続ける。
(2) When a plant is immersed in an aqueous solution having a lower concentration than the cell solution.
The cells absorb water from the outer aqueous solution through the semipermeable cell membrane and expand the protoplasm. By the way, since the plant cell has a cell wall made of a completely permeable elastic tissue outside the cell membrane, the bulging protoplasm exerts a bulging pressure that tries to push the cell wall and expands the cell wall as a reaction. It receives the wall pressure to return to the protoplasm. As the cell swells, its concentration in the cell decreases, its osmotic pressure decreases, and the swell pressure increases, and when the wall pressure equal to that is equal to the osmotic pressure in the cell, the outside of the cell Automatically stops water absorption from and continues to survive in a bulging tension.
（３）植物を濃度零の水溶液（すなわち水）に浸漬した場合。
上記（２）と同様である。。
(3) When a plant is immersed in a zero concentration aqueous solution (that is, water).
Same as (2) above. .
（４）植物を該細胞液より高濃度の水溶液に浸漬した場合。
細胞内の水が外へ浸出して原形質が収縮していき、遂には原形質分離を起す。ここで、原形質分離を起した細胞は、水溶液の濃度が植物胞液よりわずか高い程度であれば、再び水に浸すと原形質復帰を行うが、水溶液の濃度がそれよりも高いときは、多くの植物は原形質復帰が不可能となって死滅する。
(4) When a plant is immersed in an aqueous solution having a higher concentration than the cell solution.
Intracellular water leaches out and the protoplasm contracts, eventually causing protoplasm separation. Here, if the concentration of the aqueous solution is slightly higher than that of the plant follicle, the cells that have undergone protoplast separation will revert to protoplasm when immersed in water again, but when the concentration of the aqueous solution is higher than that, Many plants die because protoplasmic reversion is impossible.
本発明における上記水溶液の上記濃度である「植物の細胞液の濃度よりわずか高い濃度」とは、上記植物細胞が原形質分離を起しても原形質復帰を行うことのできる上限濃度である。実験によれば、その「わずか高い」程度は、植物の種類により異なるが、約０．１〜０．３Ｍである。 The “concentration slightly higher than the concentration of the plant cell fluid”, which is the concentration of the aqueous solution in the present invention, is an upper limit concentration at which protoplast recovery can be performed even if the plant cell undergoes protoplast separation. According to experiments, the “slightly high” degree is about 0.1 to 0.3 M, depending on the type of plant.
本発明において、水溶液の濃度を上述のように調整すれば、上記「短時間浸漬」の時間範囲は、浸漬時間の短縮という本発明の課題を第一義としつつ害虫を植物から効果的に離脱させる観点から、比較的自由に選定することができる。一例として、１回の浸漬時間が約３〜２０分で、約１０〜６０分の間隔をおいて２〜６回繰返し、この繰返し浸漬を毎日１〜３度行う。
以下本発明の実施例について説明する。
In the present invention, if the concentration of the aqueous solution is adjusted as described above, the time range of the above-mentioned “short-time immersion” effectively removes the pests from the plant while the primary object of the present invention is to shorten the immersion time. From the viewpoint of making it possible, it can be selected relatively freely. As an example, one immersion time is about 3 to 20 minutes, and it is repeated 2 to 6 times at intervals of about 10 to 60 minutes, and this repeated immersion is performed 1 to 3 times every day.
Examples of the present invention will be described below.
栽培槽内に培養液を入れ、該培養液面に浮かべた定植パネル上にホーレンソーを植え、その根を定植パネル下の培養液に浸した水耕栽培において、本例は、培養液を浸漬用水溶液として使用する例である。 In hydroponic cultivation where a culture solution is placed in a cultivation tank, a spinach is planted on a planting panel floated on the surface of the culture solution, and its root is immersed in the culture solution under the planting panel, this example is for immersing the culture solution It is an example used as an aqueous solution.
上記ホーレンソーの細胞液の濃度は約０．３Ｍ（モル濃度）であり、培養液の基本組成及びその各濃度は、硝酸カルシウム１．７７ｍＭ（ミリモル）、硝酸カリ２．３７ｍＭ、硫酸マグネシウム１．２５ｍＭ、リン酸二水素アンモニウム０．４３５ｍＭ、合計５．８２５ｍＭ（＝０．００５８２５Ｍ）で、これにＥＤＴＡ鉄、硫酸銅、硫酸亜鉛、モリブデン酸アンモニウムを微量づつ添加し、さらに有機肥料を適量加え、培養液全体の濃度を約１１．７ｍＭ（＝０．０１１７Ｍ）とホーレンソーの細胞液濃度より低く調整してある。 The concentration of the cell solution of the above spinach is about 0.3 M (molar concentration). The basic composition of the culture solution and each concentration thereof are 1.77 mM (mmol) of calcium nitrate, 2.37 mM of potassium nitrate, and 1.25 mM of magnesium sulfate. , Ammonium dihydrogen phosphate 0.435mM, total 5.825mM (= 0.005825M), EDTA iron, copper sulfate, zinc sulfate, ammonium molybdate was added in small amounts, and an organic fertilizer was added in an appropriate amount, followed by cultivation. The concentration of the whole liquid is adjusted to about 11.7 mM (= 0.0117 M), which is lower than the concentration of the cell liquid in the holenso.
気温２８°Ｃ、培養液温２０°Ｃの下での水耕栽培において、上記ホーレンソーを植えた定植パネルを適宜の手段により培養液中に約１０分間浸漬し、次に上記パネルを培養液から浮上させ、元の水耕栽培に戻しての約１５分間隔をおいた後、２回目の約１０分間浸漬を行い、ついで同じく約１５分間隔をおいて３回目の約１０分間浸漬を行った。この繰返し浸漬を毎日２度行った。 In hydroponic cultivation at an air temperature of 28 ° C and a culture solution temperature of 20 ° C, the planted panel in which the above-mentioned spinach is planted is immersed in the culture solution by an appropriate means for about 10 minutes, and then the panel is removed from the culture solution. After leaving the surface and returning to the original hydroponics for about 15 minutes, the second immersion was carried out for about 10 minutes, and then the third immersion was carried out for about 10 minutes at the same interval of about 15 minutes. . This repeated soaking was performed twice daily.
上記約１０分の浸漬によりホーレンソー細胞が上記培養液から水分を吸収して原形質を膨らませていく。細胞が膨らむにつれ細胞内の濃度及び浸透圧が低下すると共に膨圧が高まっていき、該膨圧と大きさの等しい壁圧と細胞内の浸透圧とが等しくなったとき水分の吸収を停止し、その膨らんだ状態で細胞は生き続ける。浸漬後、元の水耕栽培に戻しての約１５分の間隔の間に、膨らんだ細胞は徐々に正常に戻る。 As a result of the immersion for about 10 minutes, the spinach cells absorb moisture from the culture medium and expand the protoplasm. As the cell swells, the intracellular concentration and osmotic pressure decrease and the bulging pressure increases, and when the wall pressure and the osmotic pressure within the cell are equal, the absorption of water is stopped. In that swelled state, the cells continue to live. After the immersion, the swollen cells gradually return to normal during the interval of about 15 minutes after returning to the original hydroponics.
上記浸漬ごとに植物に付着するアブラ虫、アオ虫、ヨトウ虫、コナガ虫等の害虫が植物から離脱する。そのうちアオ虫等の比較的重い虫は培養液中に沈下して死滅し、その死がいは培養液の循環式濾過装置の濾過フィルターに回収され、又アブラ虫等の比較的軽い虫は生きたまま培養液面に浮上するので、各回の植物浸漬中に、メッシュの細い捕虫網にてこれらをすくい取り、適宜処分した。 Pests such as Brassicaa, Blue-worm, Coleoptera, Rana, etc. that adhere to the plant with each immersion are detached from the plant. Among them, relatively heavy insects such as blue worms sink and die in the culture solution, and the mortality is recovered by the filtration filter of the circulating filtration device of the culture solution, while relatively light insects such as the larvae remain alive. Since they floated on the surface of the culture solution, they were scooped with a fine mesh net with a fine mesh during each plant soaking and disposed of as appropriate.
上記実施例１と同様のホーレンソーの水耕栽培において、培養液に大量の肥料を入れ、その濃度がホーレンソーの細胞液の濃度約０．３Ｍを超える約０．４Ｍとなった例である。 This is an example in which a large amount of fertilizer is added to the culture solution and the concentration thereof becomes approximately 0.4 M, which exceeds the concentration of the cell solution of the Horren saw in the hydroponics cultivation of the same as in Example 1 above.
植物の安全を重視して、より短時間浸漬を行うこととし、一例として定植パネルを培養液中に約３分間浸漬し、次に元の水耕栽培に戻しての約２０分間隔をおいた後、２回目の約３分間浸漬、ついで同じく約２０分間隔をおいて３回目の約３分間浸漬、ついで同じく約２０分間隔をおいて４回目の約３分間浸漬を行い、この繰返し浸漬を毎日２度行った。 Emphasizing plant safety, soaking for a shorter period of time, as an example, a fixed planting panel was immersed in the culture for about 3 minutes, and then returned to the original hydroponics for about 20 minutes. After that, immerse for about 3 minutes for the second time, then immerse for about 3 minutes for the third time at intervals of about 20 minutes, and then immerse for about 3 minutes for the fourth time at intervals of about 20 minutes. I went twice a day.
上記短時間浸漬時に、植物細胞内の水分が外部に浸出して原形質が収縮していき、遂には初期の原形質分離が起きる。しかし培養液の濃度が細胞液の濃度よりも０．１Ｍ高いだけであるため、それ以上の原形質分離に進行することはない。浸漬後、元の水耕栽培に戻しての約２０分の間隔の間に、ホーレンソーはその根から吸収した水分を各細胞に供給し、それにより原形質分離を正常に復帰させる。 During the short-time immersion, the water in the plant cells is leached to the outside and the protoplasm contracts, and finally the initial protoplast separation occurs. However, since the concentration of the culture solution is only 0.1 M higher than the concentration of the cell solution, no further protoplast separation occurs. After soaking, during an interval of about 20 minutes after returning to the original hydroponics, the Horenso supplies each cell with water absorbed from its roots, thereby restoring protoplast separation to normal.
上記３分間浸漬を４回繰返すことにより植物に付着する害虫はほとんど植物から離脱した。 By repeating the immersion for 3 minutes for 4 times, most of the pests attached to the plant were detached from the plant.
なお、上記パネルの浸漬時に該パネルに軽い振動を加えると、害虫の植物からの離脱がさらに容易であった。 In addition, when light vibration was applied to the panel during the immersion of the panel, it was easier for the pests to leave the plant.
定植パネルにレタスを植え、他は実施例１と同様の水耕栽培において、上記栽培槽と別に浸漬槽を設け、該浸漬槽に浸漬用水溶液として濃度０の水溶液すなわち水を入れる。 Lettuce is planted on a fixed planting panel, and in the other hydroponics similar to Example 1, an immersion tank is provided separately from the above-described cultivation tank, and an aqueous solution having a concentration of 0, that is, water is added to the immersion tank as an aqueous solution for immersion.
上記レタス植えパネルを栽培槽から浸漬槽に移送し、そこで気温２８°Ｃ、水温２２°Ｃの下で水中に約１０分間浸漬し、ついで上記パネルを水中から浮上させ、根は水中に浸した状態で約１０分間隔をおいた後、２回目の約１０分間浸漬を行い、ついで同じく約１０分間隔をおいて３回目の約１０分間浸漬を行った。３回の浸漬後上記パネルを栽培槽に移送し、元の水耕栽培に戻した。これを毎日３度行った。 The lettuce planting panel was transferred from the cultivation tank to the immersion tank, where it was immersed in water at a temperature of 28 ° C. and a water temperature of 22 ° C. for about 10 minutes, and then the panel was floated from the water, and the roots were immersed in water. After leaving an interval of about 10 minutes in the state, the second immersion was performed for about 10 minutes, and then the third immersion was performed for about 10 minutes at the same interval of about 10 minutes. After three immersions, the panel was transferred to the cultivation tank and returned to the original hydroponics. This was done three times daily.
上記浸漬において、レタスの細胞が外部から水を吸収して原形質を膨らませるが、実施例１と同様に膨らんだ状態で細胞は生き続け、３回の浸漬後元の水耕栽培に戻した後、細胞は徐々に正常に戻る。 In the above immersion, lettuce cells absorb water from the outside and expand the protoplasm, but the cells continue to live in the expanded state in the same manner as in Example 1 and returned to the original hydroponics after 3 immersions. Later, the cells gradually return to normal.
上記１０分間浸漬を間欠的に３回行うことにより、植物が付着する害虫を植物からほとんど離脱させた。本例の場合、浸漬槽の水面に浮上する害虫は、上例と同様、浸漬時に捕虫網により回収するが、水中に沈下した害虫は、浸漬後パネルを栽培槽に移送した後、捕虫網により水中をさらって回収するとよい。
The pests to which the plant adheres were almost removed from the plant by intermittently performing the above 10 minute immersion three times. In the case of this example, the pests that float on the surface of the immersion tank are collected by a trap net when immersed, as in the above example. You should collect it.
