石井英夫,"作物の誘導抵抗性を利用した病害防除",[online],平成16年9月13−14日,[平成19年7月23日検索],インターネット<URL:http://www.niaes.affrc.go.jp/techdoc/inovlec2004/2-5.pdf>
海水中で約2〜3年間貯蔵されていたカキ殻を水道水で洗浄した後、110℃で24時間乾燥した。得られた乾燥カキ殻(10g)を金槌で細かく粉砕した後、マッフル炉(ADVANTEC社製、製品名「FUL242FA」)に入れて1050℃で3時間焼成した。次いで、常温まで炉内で放置した後、粉砕機(大阪ケミカル社製、製品名「ワンダクラッシュミルD3V−101」)で粉末状に粉砕した。得られた粉末を篩(東京スクリーン社製、製品名「Testing Sieve」、目開き:106μm)で篩い分けし、粗大な粉末を除外した。
上記実施例1で得た焼成カキ殻粉末(2g)を蒸留水(10mL)に加えてよく攪拌し、懸濁液とした。キュウリ(タキイ種苗社製、製品名「相模半白節成」)を実生1.5葉期まで育成し、綿棒に上記懸濁液を浸漬して本葉第一葉に塗布した。また、比較のために、水のみ、および上記実施例1で得た未焼成カキ殻粉末の懸濁液も同様に塗布した。
上記実施例1で得た焼成カキ殻粉末(2g)を蒸留水(10mL)に加えてよく攪拌し、懸濁液とした。キュウリ(タキイ種苗社製、製品名「相模半白節成」)を3個体ずつ1ポットに植えて実生0.5葉期まで育成し、綿棒に上記懸濁液を浸漬して2ポットのキュウリ個体(合計6個体)の子葉に塗布した。また、比較のために、水のみ、および上記実施例1で得た未焼成カキ殻粉末の懸濁液も同様に塗布した。塗布から2日後の1葉期に、胞子濃度:1×106/mLに調節したキュウリ炭疽病菌(Colletotrichum orbiculare)の胞子懸濁液を1個体当たり約2mLずつ子葉と本葉第一葉に噴霧接種した。次いで、当該キュウリ植物体ポットを暗黒湿潤条件に24時間放置した後、温度:25℃で、照度:3000luxの明環境下で16時間、および暗環境下で8時間のサイクルの日長環境制御室に入れ、3〜4日後に発病度を調査した。発病度は、病斑面積を5%未満、5%以上25%未満、25%以上50%未満、50%以上75%未満、75%以上の5段階で評価し、各階級の中央値に置換して水のみで処理した場合に対する抑制率として算出した。結果を表1に示す。また、水のみで処理したキュウリと焼成カキ殻粉末で処理したキュウリの写真を図2に示す。
