Description

  The present invention relates to a moss control agent for lawns, and more particularly to a moss control agent for lawns that controls moss that grows in the green of a golf course or the like.

In recent years, in greens such as golf courses, moss grows in and around the lawn, and particularly moss (Lycaenidae) tends to occur in a high humidity environment. As a countermeasure for controlling the moss, for example, a technique using phosphate or sulfate is known (Patent Document 1).
JP-A-11-106305

  When the sulfate described in Patent Document 1 is used as a moss control agent for lawns, the moss can be killed by spraying a phosphate or the like having a predetermined concentration or more on the lawn. Salts and the like have the drawbacks of causing damage to the human body and inhibiting the growth of the lawn.

  Also, various moss control agents using chemical substances other than the phosphates and sulfates have been tried. In this case, there is a demand for a moss control agent having a high moss control effect without causing harm to the lawn and the human body, but a moss control agent that satisfies this demand has not yet been developed and is in the stage of trial and error. It is a fact.

  Therefore, there is a technical problem to be solved in order to surely control moss that grows in the lawn and the periphery without causing harm to the human body or lawn, and the present invention solves this problem. With the goal.

  The present invention has been proposed in order to achieve the above object, and includes lauroylmethyl-β-alanine sodium, N-lauroyl N-methyl-β-alanine triethanolamine, polyoxyethylene lauryl ether sodium acetate, lauric acid Provided is a lawn moss control agent containing, as an active ingredient, one or more selected from amidopropyl betaine and sodium laurylaminodipropionate.

  According to this configuration, the five chemical substances are the main components of an anionic surfactant or an amphoteric surfactant, and usually a moss control agent for lawn containing one of them as an active ingredient. Although used, the present invention can also be applied to a moss control agent containing a combination of two or more as an active ingredient.

  Actually, when spraying the moss control agent for lawn, for example, after diluting and preparing a chemical component such as lauroylmethyl-β-alanine sodium or a surfactant containing the component to a predetermined concentration, It is sprayed on the green of golf courses that are prosperous. In this case, a predetermined amount of moss control agent is sprayed per unit area of green, but the spray amount varies depending on the dilution concentration, the temperature, and the like. By spraying an appropriate amount of moss control agent on the green of a golf course or the like, moss growing on the green is reliably controlled without harming the human body or the lawn.

Regarding the mechanism of action of the moss control agent of the present invention, in the structural formula such as lauroylmethyl-β-alanine sodium (see Chemical Formula 1), the 12th carbon atom of the hydrocarbon chain which is a hydrophobic group is moss. In particular, with respect to sodium lauroylmethyl-β-alanine, sodium polyoxyethylene lauryl ether acetate and sodium laurylaminodipropionate, the Na cation at the end of the hydrophilic group (counter) Ions) are also thought to contribute to the growth inhibition of moss.

コケ防除剤として、例えば、ラウロイルメチル−β−アラニンナトリウム溶液等のアミノ酸系界面活性剤を用いたときは、不用なコケを効果的に枯死させることができ、且つ、有用な芝生を活性化させて生長を促進させることができる。又、ラウリン酸とＮ−メチルアラニンとの縮合物のナトリウム塩である、弱酸性のラウロイルメチル−β−アラニンナトリウム溶液は、皮膚に対して感触の良い安全性の高い陰イオン性界面活性剤であるので、人体に害を与えたり、或いは、グリーンの環境を汚染させることもない。尚、本発明者が長期に亘り鋭意研究した実験結果によれば、コケ枯死効果及びグリーン環境保全効果の観点からは、ラウロイルメチル−β−アラニンナトリウムを有効成分として含有するコケ防除剤が最も優れていると言える。

For example, when an amino acid-based surfactant such as lauroylmethyl-β-alanine solution is used as a moss control agent, unnecessary moss can be effectively killed, and useful grass can be activated. Can promote growth. The sodium salt of weakly acidic lauroylmethyl-β-alanine, which is a sodium salt of a condensate of lauric acid and N-methylalanine, is a highly safe anionic surfactant that feels good against the skin. It does not harm the human body or pollute the green environment. In addition, according to the results of experiments conducted by the present inventor over a long period of time, the moss control agent containing lauroylmethyl-β-alanine sodium as an active ingredient is the most excellent from the viewpoint of moss death and green environmental conservation effects. It can be said that.

  According to the present invention, by spraying the moss control agent such as lauroylmethyl-β-alanine sodium solution on the lawn, the spray liquid penetrates into the moss that grows on the lawn, and inhibits the growth of the moss to die. be able to. At that time, since the moss control agent is formulated and sprayed at a low concentration, there is an excellent effect that there is no fear of harming humans or polluting the green environment. In particular, since lauroylmethyl-β-alanine sodium solution and N-lauroyl N-methyl-β-alanine triethanolamine solution are amino acid surfactants, they have high functions as “herbicides” that effectively kill moss. Not only has it, but also has a high function as a “fertilizer” that promotes and activates the growth of lawn.

  The present invention is selected from sodium lauroylmethyl-β-alanine, N-lauroyl N-methyl-β-alanine triethanolamine, sodium polyoxyethylene lauryl ether acetate, amidopropyl betaine laurate and sodium laurylaminodipropionate By using a lawn moss control agent that contains one or more of these ingredients as an active ingredient, it effectively kills only moss, such as unwanted ginkgo, without harming human health or lawn growth Achieved the goal of

  Hereinafter, an embodiment of the present invention will be described. The solution concentration of the moss control agent according to the present invention is usually in the range of 0.09% to 1.04%. This is because if the amount is less than 0.09%, the effect of dying the moss is remarkably reduced. On the other hand, if it exceeds 1.04%, the surfactant is excessively added, which is uneconomical. This is because there is a risk of damage to growth. The solution concentration of the moss control agent slightly varies depending on the moss growing state in the green or the temperature.

When making a moss control agent in the concentration range suitable for spraying on the lawn, for example, 3 to 18 cc of lauroylmethyl-β-alanine sodium is added to 500 cc to 1000 cc of water to make a moss control agent. evenly sprayed lawn area 1 m ^2. After spraying, it is usually left as it is, and it exerts a sufficient control effect against moss. In this case, it does not have any adverse effect on the growth of the lawn or the human skin. Note that the moss control agent of the present invention is excellent in biodegradation, and there is no risk of polluting the green environment in the short or long term, which is extremely preferable from the viewpoint of conservation of the natural environment.

  Next, the present invention is illustrated by Experimental Examples 1 to 10. Each experiment was conducted from April to June 2004 on the lawn of a golf course with abundant mushrooms. In particular, Experiments 1 to 4 were conducted at Bentonaseli, and Experiments 5 to 10 were Conducted in green.

  Incidentally, as the above lauroylmethyl-β-alanine sodium solution, N-lauroyl N-methyl-β-alanine triethanolamine solution and polyoxyethylene lauryl ether sodium acetate solution, respectively, trade names: Enadicol L-30AN, Enadicol L-30ANT And Enigcol EC-30 (both are surfactants manufactured by Lion Corporation). Further, as the lauric acid amidopropyl betaine solution and the sodium laurylaminodipropionate solution, trade names: Enadicol L-30B and Enadicol DP-30 (both surfactants manufactured by Lion Corporation) were used, respectively. Table 1 shows a list of trade names of the surfactants, names of chemical substances, and concentrations.

実験１（４月１５日、気温２２度）：種類の異なるコケ防除剤の有効成分と薬害との関係に関する比較試験を行うため、エナジコールＬ−３０ＡＮ、商品名：ライオノールＴＤＬ−２０（ポリオキシエチレンポリオキシプロピレンアルキルエーテル溶液）、エナジコールＬ−３０ＡＮＴ、リパール８７０Ｐ（ジアルキルスルホコハク酸エステルナトリウム塩溶液）、ライオノールＬ−５３５（ポリオキシアルキレンアルキルエーテル溶液）及びエナジコールＤＰ−３０の６種類のコケ防除剤２０ｃｃをそれぞれ水１０００ｃｃと混合・撹拌した。得られた６種類の各溶液の全量（１０２０ｃｃ）をそれぞれ、６箇所の各ペントグリーン１m²に対して均等に散布した。尚、前記ライオノールＴＤＬ−２０、リパール８７０Ｐ及びライオノールＬ−５３５はライオン株式会社製造の界面活性剤である。該界面活性剤の商品名、化学物質の名称及び濃度の一覧表を表２に示す。

Experiment 1 (April 15, temperature 22 degrees): In order to conduct a comparative test on the relationship between active ingredients of different types of moss control agents and phytotoxicity, Enacol L-30AN, trade name: Lionol TDL-20 (polyoxyethylene) Polyoxypropylene alkyl ether solution), Enadicol L-30ANT, Lipard 870P (Dialkylsulfosuccinate sodium salt solution), Lionol L-535 (Polyoxyalkylene alkyl ether solution) and Enadicol DP-30 Each was mixed and stirred with 1000 cc of water. The total amount (1020 cc) of each of the six types of solutions thus obtained was sprayed evenly on each pent green 1 m ^{2 at} six locations. The Lionol TDL-20, Ripar 870P and Lionol L-535 are surfactants manufactured by Lion Corporation. Table 2 shows a list of trade names of the surfactants, names of chemical substances, and concentrations.

次の日、各ペントグリーンを確認したところ、エナジコールＬ−３０ＡＮの散布区、エナジコールＬ−３０ＡＮＴの散布区及びエナジコールＤＰ−３０の散布区では、ギンゴケが枯れたが、ペント芝生は枯れなかった。一方、ライオノールＴＤＬ−２０の散布区、リパール８７０Ｐの散布区及びライオノールＬ−５３５の散布区ではいずれも、ギンゴケが枯れると同時に、ペント芝生も枯れた。２週間後及び１月後に、各ペントグリーンを確認したところ、上記と同様の結果であった。

On the next day, when each pent green was confirmed, in the spray zone of Enagicol L-30AN, in the spray zone of Enagicol L-30ANT and in the spray zone of Enagicol DP-30, the ginkgo dies but the pent lawn did not wither. On the other hand, in all of the spraying zone of Lionol TDL-20, the spraying zone of Ripar 870P, and the spraying zone of Lionol L-535, the ginkgo dies and the pent lawn withered. Each pent green was confirmed after 2 weeks and 1 month. The results were the same as above.

  Thus, in the case of a polyoxyethylene polyoxypropylene alkyl ether solution, a dialkyl sulfosuccinate sodium salt solution, and a polyoxyalkylene alkyl ether solution, phytotoxicity that inhibits the growth of pent lawn occurred, but lauroylmethyl-β -In the case of sodium alanine solution, N-lauroyl N-methyl-β-alanine triethanolamine solution, and sodium laurylaminodipropionate solution, it is possible to selectively and reliably control unnecessary ginkgo shoots without causing any phytotoxicity. There was found.

Experiment 2 (April 18, temperature 25 degrees): To conduct a comparative test on the relationship between the concentration of the moss control agent and the moss control effect, enadicol L-30AN (30% lauroylmethyl-β-alanine sodium solution) ) 15 cc was mixed and stirred with 1000 cc of water. Similarly, 5 cc of Enagicol L-30AN was mixed and stirred with 1000 cc of water. The total amount of each of the obtained two kinds of each lauroylmethyl-β-alanine sodium solution (concentration 0.44% and 0.15% after mixed dilution) was sprayed evenly over 1 m ² of ^two pent greens.

  The next day, when each pent green was confirmed, the ginkgo wilt withered in the 0.44% solution spray area, but the pent lawn did not wither. On the other hand, in the sprayed area of the 0.15% concentration solution, the chinook was not completely withered. In particular, when observed after 2 weeks, in the sprayed area with a 0.44% concentration solution, the chinoke was completely withered, but the pent lawn was grown and activated smoothly.

  In addition, after one month, when each pent green was confirmed, in the sprayed area of the 0.44% concentration solution, the chinoke was withered, but the pent lawn was not withered. On the other hand, Gingoke was not completely withered in the sprayed area of the 0.15% concentration solution.

  Thus, if the concentration of the lauroylmethyl-β-alanine sodium solution is 0.15%, the withering effect on Gingoke decreases, whereas if the concentration is about 0.44%, the withering effect on Gingoke is only high. Rather, it has been found that it also serves as a “fertilizer” that promotes the growth of pent lawns.

In order to confirm the upper and lower limits of the effective concentration of the moss control agent of the present invention,
The same spraying test as described above was performed by changing the concentration of -30AN. As a result, when the concentration exceeded 1.04%, the concentration of the moss control agent was excessive, and phytotoxicity was observed against the growth of the lawn. On the other hand, when the concentration was less than 0.09%, the effect of killing Gingoke was significantly reduced. Therefore, it was confirmed that the concentration is preferably in the range of 0.09% to 1.04%.

Experiment 3 (April 23-Air temperature 16 degrees, 24 days-Air temperature 17 degrees, 25 days-Air temperature 20 degrees): In order to conduct a test on phytotoxicity when moss control agent is continuously sprayed on the same location, April 23 , Enigol L-30AN2 liter was mixed and stirred with 100 liters of water. The entire amount of the obtained aqueous solution (diluted concentration 0.59%) was sprayed evenly over 100 m ² of pent green. The same spraying test as described above was carried out on the 24th and 25th in the same location of Pent Green. That is, the spraying test was carried out for 3 consecutive days with the 23rd as the first day.

  The next day, when the pent green was confirmed, the chinoke dies with no hindrance to the growth of the pent lawn. In addition, when this green was confirmed after two weeks and one month, the chinoke was withered without inhibiting the growth of the pent lawn. Thus, even if a 0.59% concentration of sodium lauroylmethyl-β-alanine solution is sprayed continuously for 3 days, no phytotoxicity is observed on the pent lawn, and the pent lawn can grow smoothly. found.

Experiment 4 (April 28, temperature 15 degrees): To test phytotoxicity when moss control agents are used in combination with fertilizers and chemicals, edicol L-30AN is mixed with water to give a moss concentration of 0.59% The control agent was made 102 liters, and 250 g of liquid fertilizer, 100 cc of insecticide and 10 g of fungicide were mixed and stirred. The entire amount of the obtained mixed solution was evenly sprayed on 100 m ² of pent green.

  The next day, when the pent green was confirmed, the chinoke was withered without inhibiting the growth of the pent lawn. In addition, when this green was confirmed after 2 weeks and 1 month, the chinoke was completely withered without inhibiting the growth of the pent lawn. Thus, the moss control agent containing lauroylmethyl-β-alanine sodium as an active ingredient is mixed with a liquid fertilizer, an insecticide or the like and sprayed onto the pent lawn. It was found that no phytotoxicity occurred.

Experiment 5 (April 29, temperature 24 degrees): Since the spraying test in Bentonase was completed, the spraying test on the surface of this green 5 was tried next. In the same manner as above, Enadicol L-30AN was diluted with water to obtain a 0.53% sodium lauroylmethyl-β-alanine solution, which was evenly sprayed on the surface of the main green. In this case, the actual spray amount of Enagicol L-30AN (before dilution) per 1 m ^{2 of the} green was 18 cc. At that time, in order to increase the permeation of the spray liquid, water was sprinkled on the ground surface of the green for about 5 minutes using a sprinkler before spraying.

The next day, when I checked this green, the chinoke dies without hindering the growth of the lawn. In addition, when the green was confirmed after two weeks and one month, the gingko was still dead. Thus, after increasing the penetration of the spray liquid into the ground, even if 18 cc of Enagicol L-30AN (before dilution) is sprayed per 1 m ^{2 of the} green, the ginkgo is effectively removed without harming the green lawn. It was found that it can be controlled.

Experiment 6 (May 6, temperature 15 degrees): In order to attempt a spray test on the surface of the main green (without prior watering), a lauroylmethyl-β-alanine sodium solution having a concentration of 0.53% was obtained as described above. This was evenly spread on the surface of the main green 10. In this case, the actual spray amount of Enagicol L-30AN (before dilution) per 1 m ^{2 of the} green was 18 cc.

The next day, when I checked the green, the chinoke was dead. However, since water was not sprayed in advance, the spray liquid did not penetrate into the ground, and the components of the spray liquid touched the leaves directly, and the green lawn yellowed into footprints. The yellowed part seems to be the footprints of the spreaders. On the next day, a similar spraying test was conducted, but there was still a phytotoxicity that caused the green lawn to turn yellow into a footprint. In addition, when this green was confirmed after two weeks and one month, the chinoke was withered without harming the growth of the lawn.

Experiment 7 (May 8, temperature 24 degrees): Considering the previous phytotoxicity, in order to investigate the relationship between spraying amount and phytotoxicity, a lauroylmethyl-β-alanine sodium solution with a concentration of 0.27% was used in the same manner as described above. This was spread evenly on the surface of the main green. In this case, based on the phytotoxicity in Experiment 6, the actual spray amount of Enazicol L-30AN (before dilution) per 1 m ^{2 of} this green was halved from 18 cc to 9 cc. At that time, in order to increase the penetration of the spray liquid into the ground, the green was sprinkled with a sprinkler for about 5 minutes before spraying.

  The next day, two weeks later and one month later, when the green was confirmed, the ginkgo wilt withered without any phytotoxicity in the growth of the lawn. Thus, even if the actual spray amount of Enagicol L-30AN (before dilution) is halved to 9 cc, it has been confirmed that gingko moss is withered, and the occurrence of phytotoxicity can be avoided by appropriately adjusting the substantial spray amount. found.

Experiment 8 (May 14; temperature 26 ° C.): In order to examine the relationship between the actual spray amount and the change in temperature, a lauroylmethyl-β-alanine sodium solution having a concentration of 0.18% was obtained in the same manner as described above. Evenly spread on the surface. In this case, based on the consideration of the previous experiment 7, taking into account that the temperature is 26 degrees, 2 degrees higher than the previous time, the actual application amount of Enagicol L-30AN (before dilution) per 1 m ^{2 of} this green Further reduction from 9 cc to 6 cc. At that time, in order to increase the penetration of the spray liquid into the ground, the green was sprinkled with a sprinkler for about 5 minutes before spraying.

  The next day, 2 weeks and 1 month later, the green was confirmed, but at any time no phytotoxicity was seen in the growth of the lawn, and the chinook was completely withered. That is, since the temperature was increased from 24 degrees to 26 degrees, the ginkgo dies withered even when the actual spray amount of Enagicol L-30AN (before dilution) was reduced to 6 cc. Thus, it has been found that the effective spray rate effective for moss control is closely related to the temperature, and the higher the temperature, the smaller the effective spray rate.

  Experiment 9 (May 21): When all the parts of the bent green sprayed with the moss control agent were observed at the same time, no gingoke was seen in all the lawns. Moreover, it was confirmed that the growth of lawn was activated in the place where not only gingoke disappeared but also the spraying of Enagicol L-30AN was repeated. The reason why lawn growth was activated was probably that lauroylmethyl-β-alanine sodium, which is an active ingredient of enadicol L-30AN, was an amino acid-based surfactant, and in particular, alanine contributed effectively to lawn growth activation. Presumed to be.

  Experiment 10: Based on the results of the above Experiments 1 to 9, the following comparative tests were conducted in order to identify the effective components for the decline of chinoke and the activity of the lawn. That is, 10 kinds of spraying liquids having different components or substantial spraying amounts were sprayed on 10 spraying sections of bentonasery on a sunny day and a temperature of 29 ° C.

Ten types of spray liquids are Enacol L-30B (9 cc / m ² ), Enacol L-30ANT (9 cc / m ² ), Enacol EC30 (9 cc / m ² ), Enacol L-30AN (9 cc / m ² ), Alanon ALE (9 cc / m ² ), Alanon ACE (9 cc / m ² ), Softazoline CH-R (9 cc / m ² ), Softazoline LPB-R (9 cc / m ² ), Enagicol L-30AN (3 cc / m ² ) and Enadicol L-30AN (20 cc / m ² ), and each diluted solution of these surfactants was sprayed evenly at 10 locations of the bentonasery.

That is, for Enagicol L-30B, Enagicol L-30ANT, Enagicol EC30, Enagicol L-30AN, Allanone ALE, Allanone ACE, Softazolin CH-R and Softazolin LPB-R, each of these surfactants 9 cc is mixed with 500 cc of water. The total amount of each mixture was sprayed evenly on 1m ² of bentonasery. In particular, for Enagicol L-30AN, 3 cc and 20 cc thereof were mixed with 500 cc of water in the same manner as described above, and the total amount of each mixed solution was sprayed evenly on 1 m ² of bentonasery.

Table 10 collectively shows the ten sections where these sprays are sprayed. In addition, the inside of () shows the actual spraying quantity cc of each surfactant (before dilution), such as Enagicol L-30AN, per 1 m ^{2 of} lawn.

上記ソフタゾリンＣＨ−Ｒ及びソフタゾリンＬＰＢ−Ｒは両性界面活性剤であるが、その他の散布液は全て陰イオン界面活性剤である。ここで、前記界面活性剤の商品名、化学物質の名称及び濃度の一覧表を表４に示す。尚、アラノンＡＬＥ、アラノンＡＣＥ、ソフタゾリンＣＨ−Ｒ及びソフタゾリンＬＰＢ−Ｒは川研ファインケミカル株式会社製造の界面活性剤である。

The above-mentioned softazoline CH-R and softazoline LPB-R are amphoteric surfactants, but all other spray liquids are anionic surfactants. Table 4 shows a list of trade names of the surfactants, names of chemical substances, and concentrations. Alanon ALE, Alanon ACE, Softazoline CH-R and Softazoline LPB-R are surfactants manufactured by Kawaken Fine Chemical Co., Ltd.

翌日、前記ベントナセリーにおける１０箇所の散布区画を観察したところ、エナジコールＬ−３０ＡＮ（３ｃｃ／m²）を散布した区画では、高温２９℃の条件下に、コケ枯死効果を奏する芝生１m²当たりの有効実質散布量を散布したので、実質散布量が３ｃｃ／m²と少なくても、十分なコケ枯死効果が認められた。又、エナジコールＬ−３０ＡＮ（２０ｃｃ／m²）を散布した区画では、芝生に対して薬害を生じたが、これは高温２９℃の条件下において、過剰な実質散布量２０ｃｃ／m²を散布したことによるものと考えられる。

On the next day, 10 spraying sections in the bentonaserie were observed, and in the section sprayed with Enacicol L-30AN (3 cc / m ² ), it was effective per 1 m ^{2 of} lawn that had a moss death effect under high temperature conditions of 29 ° C. Since the actual spray rate was sprayed, even if the actual spray rate was as small as 3 cc / m ² , a sufficient moss death effect was observed. Moreover, in the section sprayed with Enagicol L-30AN (20 cc / m ² ), phytotoxicity was caused to the lawn, but this sprayed an excessive substantial spray amount of 20 cc / m ² under the condition of a high temperature of 29 ° C. This is probably due to this.

According to the above experimental results, the required moss in each spraying section of softazolin CH-R and softazolin LPB-R is larger than that in other spraying sections such as the energic L-30AN (9 cc / m ² ) spraying section. The withering effect was not obtained.

  Here, it is common to the spraying sections that exhibit the moss mortality effect (moss control effect) more than necessary, that is, the sections sprayed with Enagicol L-30B, Enagicol L-30ANT, Enagicol L-30AN, Enagicol EC30, Allanone ALE and Allanone ACE. As a result of investigation on the active ingredient of the moss control agent, the chemical formula of the moss control agent has a C atom part at the 12-position of the hydrocarbon chain, that is, a lauroyl component is effective in inhibiting moss growth. In particular, it was found that sodium lauroylmethyl-β-alanine, which is the main component of enadicol L-30AN and Alanon ALE, has the highest moss control effect.

  Immediately after spraying the moss control agent in the above experiment, the growth situation of Gingoke was observed. As a result, the moss control agent quickly penetrated into the moss, and the Gingoke started to turn yellow after about 3 hours without harming the lawn. It was confirmed.

  In the above examples, lauroylmethyl-β-alanine sodium, N-lauroyl N-methyl-β-alanine triethanolamine, polyoxyethylene lauryl ether acetate sodium, amidopropyl betaine laurate and sodium laurylaminodipropionate Although the moss control agent having one selected as an active ingredient has been described, a combination of two or more selected arbitrarily may be used as an active ingredient, and a solution having a predetermined concentration containing two or more may be added to the lawn. Even if sprayed, the same effect as when a solution containing one kind is sprayed can be expected.

  The present invention can be applied not only to golf courses but also to lawns in parks, ball games, gardens, etc. In this case, it has a high control effect against moss of bryophytes such as ginkgo that grows on the lawn.

It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified one.
