Many techniques have been developed and utilized to cultivate and manage lawns such as parks or golf courses in a healthy state and to use them effectively. Especially, it is important to look beautiful in turf cultivation. When turf is violated by a disease and a symptom of damage occurs, aesthetics are greatly impaired. Agricultural chemicals have been developed and used.
Among them, tolcrofos methyl has long been used for many turf diseases such as snow rot at golf courses. (For example, see Patent Documents 1, 2, and 3)

Thereafter, the disease was promoted by placing it for 14 days under excessive humidity. In order to examine the disease control effect of the chemical solution, the disease area ratio was visually examined, and the control value was determined based on the following formula.

防除価(%)=100×(P−W)/P
P:無処理区発病面積率(%)
W:各薬剤処理区発病面積率(%)
E:コルビーの理論値=(X+Y)−(X×Y)/100
X:A剤の防除価
Y:B剤の防除価
Control value (%) = 100 × (P−W) / P
P: Untreated area disease area rate (%)
W: Disease area ratio (%)
E: Theoretical value of Colby = (X + Y) − (X × Y) / 100
X: Control value of agent A Y: Control value of agent B

その結果、驚くべきことに本発明防除剤は、相乗効果として当業者により予想される防除効果(即ち、コルビーの理論値)に対して15.3ポイント、29.1ポイントも優れた効果(即ち相乗効果)を示した。 As a result, surprisingly, the control agent of the present invention has 15.3 points and 29.1 points which are superior to the control effect expected by those skilled in the art as a synergistic effect (that is, the theoretical value of Colby) (ie, A synergistic effect).

試験例2(ポット試験:ベントグラスの紅色雪腐病に対する防除効果試験)
ベントグラス(ペンクロス)の種をプラスチックポットに播種し、温室内で約1ヶ月栽培し、当該芝の草丈を10mm程度にハサミを用いて刈り込した。その後、製剤例5〜6で調製された本発明組成物を、所定濃度になるように水で希釈した後、当該薬剤を当該芝の茎葉に対して、液量が500ml/mになるように散布した。芝の茎葉に付着した薬液が風乾した後、PDA培地で2週間培養されたMonographella nivalisの胞子懸濁液(105cfu/ml)を、そのまま芝の茎葉表面に1ポット当たり2ml噴霧接種した。その後、過湿条件下で14日間置くことにより、発病を促進させた。当該薬剤の病害防除効果を調べるために、発病を目視調査し、下記式に基づき防除価を求めた。
Test Example 2 (Pot test: Bentgrass control test against red snow rot)
Bentgrass (pencloth) seeds were sown in a plastic pot, cultivated in a greenhouse for about 1 month, and the grass height of the grass was cut to about 10 mm using scissors. Then, after diluting the composition of the present invention prepared in Formulation Examples 5 to 6 with water to a predetermined concentration, the amount of the drug is 500 ml / m 2 with respect to the grass foliage. Sprayed on. After the chemical solution adhering to the shoots and leaves of the turf was air-dried, the spore suspension of Monographella nivalis (10 5 cfu / ml) cultured in PDA medium for 2 weeks was spray-inoculated on the surface of the shoots and leaves as it was. Thereafter, the disease was promoted by placing it for 14 days under excessive humidity. In order to investigate the disease control effect of the drug, the disease was visually examined and the control value was determined based on the following formula.

調査基準 0:発病無し、1:発病面積率25%未満、2:発病面積率25%以上50%未満、4:発病面積率50%以上
発病度=(発病指数×該当ポット数)/4×調査ポット数
防除価(%)=100×(P−W)/P
P:無処理区発病度
W:各薬剤処理区発病度
E:コルビーの理論値=(X+Y)−(X×Y)/100
X:A剤の防除価
Y:B剤の防除価
Survey Criteria 0: No disease, 1: Disease area rate of less than 25%, 2: Disease area rate of 25% or more and less than 50%, 4: Disease area rate of 50% or more, Disease severity = (Pathogenesis index x number of pots) / 4x Survey pot number control value (%) = 100 × (P−W) / P
P: Untreated section disease severity W: Each drug treatment district disease severity E: Theoretical value of Colby = (X + Y) − (X × Y) / 100
X: Control value of agent A Y: Control value of agent B

その結果、驚くべきことに本発明防除剤は、相乗効果として当業者により予想される防除効果(即ち、コルビーの理論値)に対して29.2ポイント、18.7ポイントも優れた効果(即ち、相乗効果)を示した。
以上の2つの試験結果より、コルビーの理論値(E)と比較して顕著に高い防除価を示したことから、本発明組成物は優れた相乗作用を有することが示された。従って本発明により、単に混合した時に得られる相加効果以上の相乗効果を得ることができ、防除可能な病害の種類が多くなるとともに、その施用量を減少させることを可能とした。
As a result, surprisingly, the control agent of the present invention has an excellent effect of 29.2 points and 18.7 points on the control effect expected by those skilled in the art as a synergistic effect (ie, the theoretical value of Colby) (ie, A synergistic effect).
From the above two test results, since the control value was significantly higher than the theoretical value (E) of Colby, it was shown that the composition of the present invention has an excellent synergistic effect. Therefore, according to the present invention, it is possible to obtain a synergistic effect that is greater than the additive effect obtained by simply mixing, to increase the types of diseases that can be controlled, and to reduce the application rate.

本発明により、十分な芝病害防除効果が維持されるとともに投下薬剤量を減少させることが可能となる。   According to the present invention, it is possible to maintain a sufficient lawn disease control effect and reduce the amount of drug dropped.
