Abstract
Description
本発明は、殺虫作用をもつ水溶性農薬の施用に当たって添加使用する農薬補助剤に関し、この補助剤を添加した水溶性農薬の施用方法にも関する。 The present invention relates to an agrochemical adjuvant that is added and used in the application of a water-soluble pesticide having an insecticidal action, and also relates to a method for applying the water-soluble pesticide to which this adjuvant is added.
農作物に対する虫の害を防ぐ目的で施用される殺虫剤であって、水溶性のものは、たとえば「オルトラン水和剤」（武田製薬）や「ランネート水和剤」（三共製）など、さまざまなものが用いられており、いずれも害虫の体内に浸透して神経毒として作用し、殺虫効果を生じるものである。これらの農薬は、通常、水で１０００倍とか１５００倍とかの濃度に希釈して、１週間ごとに虫の多い時期に畑に散布するといった方法で施用されている。 Insecticides applied for the purpose of preventing insect damage to crops, water-soluble ones include various types such as “Ortran wettable powder” (Takeda Pharmaceutical) and “Runnate wettable powder” (Sankyo). All of them are used to penetrate into the body of a pest and act as a neurotoxin, producing an insecticidal effect. These pesticides are usually applied by a method of diluting with water to a concentration of 1000 times or 1500 times and spraying the field every week at a time when there are many insects.
ところが、連続して使用することにより、害虫に農薬に対する耐性が生じ、効果が低下することが経験された。作物の生長とともに農薬の散布回数が重なってくると、以前より高濃度で、つまり低希釈度で使用せざるを得なくなる。このような農薬使用は、農業のコストを高めることはいうまでもないが、それ以前に、作業者にとっての危険が高まり、かつ、環境に対する負荷を増すことであって、好ましくない。 However, it has been experienced that the pests are resistant to pesticides due to continuous use, and the effect is reduced. If the number of spraying pesticides overlaps with the growth of the crop, it will be forced to use at a higher concentration than before, that is, at a lower dilution. The use of such agrochemicals is not preferable because it increases the cost of agriculture, but before that, it increases the danger to workers and increases the burden on the environment.
こうした問題を解決する一つの策として、水溶性の殺虫作用をもつ農薬の使用に当たり、農薬が害虫の体内に浸透することを助け、それによって殺虫効果を高めて、農薬使用量が次第に増加することを避けることができるような補助剤を併用することが試みられている。そのような補助剤として、木炭製造時の副産物である木酢液を使用することが提案された。しかし、実用してみると、その効果はあまり顕著なものとはいえないことがわかった。 One solution to this problem is to use water-soluble pesticides that help the penetration of pesticides into the body of the pests, thereby increasing the insecticidal effect and gradually increasing the use of pesticides. Attempts have been made to use adjuvants that can avoid the above. As such an auxiliary agent, it has been proposed to use a wood vinegar solution which is a by-product during the production of charcoal. However, when it was put into practical use, it was found that the effect was not so remarkable.
発明者らは、水溶性殺虫剤に対し、木酢液に加えて酢酸エチルをあわせて併用することにより、意図した殺虫効果の増大が実現することを知った。その実施態様は、容量割合で、木酢液１０部に酢酸エチル１部を混合し、２週間程度放置して熟成させた補助剤液を、水で５００倍に希釈した農薬に添加し、１週間ごとに散布する、というものである。続いて発明者らは、木酢液＋酢酸エチルの系に、さらに若干のエタノールを添加するとよいことも見出して、あわせて開示した（特許文献１）。
しかし、この補助剤の実用試験の過程で、発明者らは、効果のバラツキの大きいことに悩まされた。たとえば、同じ殺虫剤に対して同じ生産者の木酢液を同量使用しても、殺虫効果（１回の施用で死ぬ害虫の率として）において、ときに８５％であったり、９５％に達したり、ときには５０％と低くなったりする。その原因を追及したところ、木酢液というものが、その原料となる木材の種類や、木炭製造の条件などによって、組成する成分の種類や含有量が大きく変動するためであろうという結論に達した。 However, in the course of practical testing of this adjuvant, the inventors were troubled by the large variation in effect. For example, using the same amount of wood vinegar of the same producer for the same pesticide, the insecticidal effect (as a percentage of pests that die from a single application) is sometimes 85% or even 95%. Or sometimes as low as 50%. After pursuing the cause, we reached the conclusion that the wood vinegar liquor would be due to the fact that the type and content of the components to be composed fluctuate greatly depending on the type of wood used as the raw material and the conditions for producing charcoal. .
農薬に対する補助剤の使用効果が不安定であるという問題は、木酢液の使用量を増すことにより、ある程度改善されることがわかったが、一方で、木酢液の含有量を高めた農薬補助剤を加えた農薬を、キャベツやレタスのような「葉もの」に属する作物に対して使用すると、しばしば「葉やけ」と呼ばれる黄変が生じて、商品価値を失わせることも経験した。木酢液には、ホルムアルデヒドが含まれていることが判明したほか、ダイオキシンが伴っている危険があり、その使用は慎重にすべきであるという意見も出ている。 The problem that the effect of the use of adjuvants on agricultural chemicals is unstable has been found to be improved to some extent by increasing the amount of wood vinegar used, but on the other hand, the content of wood vinegar is increased. We have also experienced the loss of commercial value, when yellowing pesticides, such as cabbage and lettuce, are often used for crops belonging to “leaves” such as cabbage and lettuce. In addition to the fact that pyroligneous acid was found to contain formaldehyde, there is also the opinion that its use should be cautious because of the dangers associated with dioxins.
その後さらに研究を進めた発明者らは、木酢液に代えて、それよりも安価であり入手も容易な酢酸が使用可能であること、および、酢酸＋酢酸エチル＋エタノールの系にすると、木酢液を使用する場合に必要な放置熟成が不要になって、混合して直ちに使用可能な均質な液となること、また、この三成分からなる補助剤は、農薬の殺虫作用を増強する効果がいっそう高いことを見出した。 After that, the inventors further studied that, instead of wood vinegar, acetic acid, which is cheaper and easier to obtain, can be used. This product eliminates the need for neglected aging when used, and can be used as a homogeneous solution that can be used immediately after mixing. In addition, these three-component adjuvants are more effective in enhancing the insecticidal action of agricultural chemicals. Found it expensive.
本発明の目的は、上述の、発明者らが得た新しい知見を活用し、水溶性の殺虫作用を有する農薬の施用に当たって使用する補助剤であって、安価で容易に調製することができ、農薬の効果をいっそう高め、それによって害虫が耐性を獲得することを抑え、農薬の使用濃度を次第に高くすることを余儀なくされる、といった好ましくない事態を生じないようにする補助剤と、その使用方法とを提供することにある。 The object of the present invention is to use the above-mentioned new knowledge obtained by the inventors, and is an auxiliary agent used in the application of a water-soluble pesticide having an insecticidal action, which can be easily prepared at a low price, Auxiliary agents that increase the effectiveness of pesticides, thereby preventing pests from gaining resistance and avoiding the undesired situation of being forced to gradually increase the concentration of pesticides used, and how to use them And to provide.
本発明の農薬補助剤は、殺虫作用をもつ水溶性農薬の施用に当たって添加使用する農薬補助剤であって、容量基準で、酢酸エチル１００重量部に対し、酢酸（氷酢酸として）１３０〜２５０部およびエタノール（無水アルコール換算で）６〜５０部を配合してなるものを、その原液とする。 The agrochemical adjuvant of the present invention is an agrochemical adjuvant that is added and used for application of a water-soluble pesticide having an insecticidal action, and acetic acid (as glacial acetic acid) 130 to 250 parts per 100 parts by weight of ethyl acetate on a volume basis. A mixture of 6 to 50 parts of ethanol (in terms of anhydrous alcohol) is used as the stock solution.
この農薬補助剤を使用することにより、農薬に補助剤を添加したものを放置熟成する必要がなくなり、かつ、添加の効果が安定して得られるようになる。その結果、水溶性の殺虫剤が害虫の体内に浸透することが容易になり、殺虫効果が高まり、連続使用しても害虫が耐性を獲得する余裕がなく死滅し、したがって農薬の使用濃度を次第に高めなければならなくなる、という事態が避けられる。これは、農業のコストを低下させるだけでなく、作業者の危険を減らし、環境に対する負荷を軽減するという利益をもたらす。 By using this agrochemical adjuvant, it becomes unnecessary to leave and age the agrochemical added with the adjuvant, and the effect of the addition can be stably obtained. As a result, it becomes easier for water-soluble insecticides to penetrate into the body of pests, increasing the insecticidal effect, and even if used continuously, the pests die without being able to gain resistance, so the concentration of pesticides is gradually increased. The situation of having to raise is avoided. This not only lowers the cost of agriculture, but also brings the benefits of reducing worker risks and reducing the burden on the environment.
上記の原液は、水で２〜１０倍に希釈した農薬補助剤の水溶液の形で使用することが便宜である。 The above stock solution is conveniently used in the form of an aqueous solution of an agrochemical adjuvant diluted 2 to 10 times with water.
本発明の殺虫作用をもつ水溶性農薬の施用方法は、散布に適した濃度に水で希釈した水溶性農薬に対して、請求項１に記載した農薬補助剤の原液または請求項２に記載した農薬補助剤の水溶液を、農薬の有効成分に対する農薬補助剤の有効成分の割合が、重量で、１００：４〜８となるように添加混合し、散布することからなる。 The method for applying a water-soluble pesticide having an insecticidal action according to the present invention is the stock solution of the pesticide auxiliary agent according to claim 1 or the water-soluble pesticide diluted with water to a concentration suitable for spraying. It consists of adding and mixing and spraying the aqueous solution of an agricultural chemical adjuvant so that the ratio of the active ingredient of an agricultural chemical adjuvant with respect to the active ingredient of an agricultural chemical may be 100: 4-8 by weight.
本発明の農薬補助剤を構成する各成分のうち、農薬が害虫の体内へ浸透することを助ける中心的な成分は、酢酸エチルである。これに対し、酢酸およびエタノールは、エステルである酢酸エチルを構成する原料物質であって、水に対して均質に溶解させることが困難な酢酸エチルを、これらの物質が存在することにより、容易に溶解させて均質な溶液を得ることを容易にするというはたらきがある。つぎに、これらの二成分は、酢酸エチルと共存することによって、水溶性の殺虫剤と浸透剤である酢酸エチルとを媒介し、浸透作用の増強に役立つものと解される。前記のように、エタノールは、その添加により、補助剤原液の調製時に放置熟成させる必要がなくなる。 Of the components constituting the agricultural chemical adjuvant of the present invention, ethyl acetate is a central component that helps the agricultural chemicals penetrate into the body of pests. On the other hand, acetic acid and ethanol are raw materials that constitute ethyl acetate, which is an ester, and ethyl acetate that is difficult to dissolve homogeneously in water can be easily dissolved by the presence of these substances. It works to make it easier to dissolve and obtain a homogeneous solution. Next, it is understood that these two components coexist with ethyl acetate, thereby mediating a water-soluble insecticide and a penetrating agent, ethyl acetate, and enhancing the osmotic action. As described above, the addition of ethanol eliminates the need for standing aging during preparation of the auxiliary agent stock solution.
原液の組成割合を上記のように決定した理由は、酢酸エチルが農薬補助剤の主成分として示す作用に対して、酢酸およびエタノールは、それぞれの下限値である１３０部および６部以上を添加しないと、上記した媒介作用が不十分であり、一方、上限である２５０部および５０部を超えて添加すると、かえって酢酸エチルの作用にとってマイナスとなるからである。 The reason why the composition ratio of the stock solution is determined as described above is that acetic acid and ethanol do not add the lower limit values of 130 parts and 6 parts or more, respectively, to the action of ethyl acetate as the main component of the agricultural chemical adjuvant. This is because the above-mentioned mediating action is insufficient, while addition exceeding the upper limit of 250 parts and 50 parts is rather negative for the action of ethyl acetate.
酢酸は、前記のように「氷酢酸として」の存在量を基準にするが、これはいうまでもなく、化学物質としての酢酸の量が問題だからである。酢酸にはさまざまな濃度の水溶液が市販されており、それらのいずれも、濃度さえ正確にわかっているものは使用可能である。エタノールに関しても同様であって、配合割合としては「無水アルコール換算で」量を定めるが、実際上は、一定の水分を伴った共沸組成物の方が安価であり、入手容易であるから、それを使用することが得策である。配合に当たっては、いったん原液を用意してそれを希釈してもよいが、直接水溶液にすることもでき、通常はそれが便宜である。その場合、酢酸とエタノールに含まれる水分を考慮に入れて残りの水分量を計算し、各成分を混合して撹拌すればよい。 As described above, acetic acid is based on the abundance of “as glacial acetic acid”, but it goes without saying that the amount of acetic acid as a chemical substance is a problem. Various concentrations of aqueous solutions are commercially available for acetic acid, any of which can be used if the concentration is known accurately. The same applies to ethanol, and the amount is determined as `` anhydrous alcohol conversion '' as the blending ratio, but in practice, an azeotropic composition with a certain amount of water is cheaper and easier to obtain, It is a good idea to use it. In blending, a stock solution may be prepared once and diluted, but it can also be directly made into an aqueous solution, which is usually convenient. In that case, it is only necessary to calculate the remaining water amount in consideration of water contained in acetic acid and ethanol, and to mix and stir each component.
本発明の農薬補助剤が有効な殺虫剤は、水溶性であって害虫に神経毒として作用するものであれば、種々ある。市販されている代表的な農薬を挙げれば、前記した例のほか、つぎのようなものがある。

There are many types of crops that are subject to application of water-soluble insecticides, but the following can be cited, and they can be applied to various cultivation forms such as open field, house cultivation, and tunnel cultivation.
(From early spring to summer)
Cabbage, Chinese cabbage, eggplant, pumpkin, cucumber, carrot, cucumber, tomato, burdock, corn, beans, okra, shiso, pepper, pepper, lettuce, spinach, radish, potato, sweet potato, soybean, red beans and other beans, melon, watermelon , Plum, yuzu, pear, plum, chestnut, peach, flower, flowering tree, grape, kanpyo, flower tobacco, tobacco, tea (from summer to autumn)
Lettuce, Chinese cabbage, cabbage, carrot, eggplant, cucumber, radish, spinach
本発明の農薬補助剤を配合することにより、水溶性の殺虫剤が効果を示す害虫の種類は変更なく、たとえば下記の害虫に対して有効である：アブラムシ、ヨトウムシ、アオムシ、毛虫（栗に付くもの）、コナガ、ハダニ、アメリカシロヒトリ、チャガラ。
ただし、得られる殺虫効果には、害虫の種類による差が見られる。たとえば、常用の殺虫剤の場合、アオムシ、ヨトウムシ、コナガに対しては、農薬の希釈倍率にして４００〜５００倍のものが必要であり、耐性を獲得しやすいといわれるアブラムシ、ハダニに対しては、５００〜２０００倍で有効である。
By incorporating the agrochemical adjuvant of the present invention, the types of insect pests in which the water-soluble insecticide is effective are not changed, and are effective against, for example, the following insect pests: aphids, weevil, caterpillars, caterpillars (attached to chestnuts) Stuff), diamondback moth, spider mite, white-faced hitori, chagara.
However, the insecticidal effect obtained varies depending on the type of pest. For example, in the case of conventional insecticides, aphid, 400, and 500 times as the dilution ratio of pesticides are necessary for aphids, worms, and komaga, and for aphids and spider mites that are said to be easy to acquire resistance. 500 to 2000 times.
殺虫剤の中には、粒剤として販売され、その粒を撒くものがあり、とくに農作物栽培の最初の段階において多く用いられる。粒剤を撒いた場合は、それに続く農薬散布に当たって、本発明の農薬補助剤を添加した液剤を施要すればよい。液剤の散布は、１週間に１回程度、その農作物が生育している期間中、施要することが望ましいが、通常は、数回の施用で目的を達することができるであろう。 Some insecticides are sold as granules and sow the grains, and are often used especially in the first stage of crop cultivation. When a granule is sown, a liquid preparation to which the agricultural chemical adjuvant of the present invention is added may be applied for the subsequent application of the agricultural chemical. It is desirable to apply the solution about once a week during the period when the crop is growing, but usually the application can be achieved by applying several times.
