試験例2 フザリウム菌罹病に対する防除効果試験
方法
前培養として、PDA培地を用いてフザリウム菌を平板培養した。70%エタノールに浸漬した後滅菌水で洗浄したニンジン片(約1cm)約10個を培地上の菌叢へ置床し28℃で5日間培養した。7月11日、培地から罹病したニンジン片を剥がし、10個を網袋に入れ、これを耕起後ビニル被覆前の圃場へ深度別(5cm又は15cm)に埋設した。
Test Example 2 Control Effect Test for Fusarium Disease Disease Method As a pre-culture, Fusarium bacteria were plated using a PDA medium. About 10 carrot pieces (about 1 cm 3 ) immersed in 70% ethanol and washed with sterilized water were placed on the fungus on the medium and cultured at 28 ° C. for 5 days. On July 11, the diseased carrot pieces were peeled off from the culture medium, 10 pieces were put in a net bag, and this was buried in a field (5 cm or 15 cm) at different depths in the field before vinyl covering after plowing.

試験区内へタンポール(グラスファイバー製トンネル用支柱)を約2mおきにアーチ状に設置後、ビニルマルチでトンネル状に被覆した。2日後、発明製剤を試験区端からマルチ内へ処理した。比較製剤は、試験区中央マルチ内に製品を置いて処理した。マルチの撤去は処理7日後に行った。   Tampoles (glass fiber tunnel struts) were installed in the test section in an arch shape every 2 m, and then covered with a vinyl mulch in a tunnel shape. Two days later, the inventive preparation was processed from the end of the test section into the mulch. Comparative formulations were processed by placing the product in the test center central mulch. The removal of the mulch was performed 7 days after the treatment.

マルチ撤去直後、罹病ニンジン片入り網袋を掘り出し、選択培地を分注したシャーレへニンジン片5ヶずつをピンセットで置き、室温、散光条件下で8日間培養した。   Immediately after the removal of the mulch, a net bag containing carrot pieces was excavated, and 5 pieces of carrot pieces were placed with tweezers in a petri dish to which a selective medium was dispensed, and cultured for 8 days at room temperature under diffused conditions.

フザリウム菌に対する殺菌効果は、選択培地(下記参照)上に置床したニンジン片の周囲の培地上におけるフザリウム菌の菌叢(各接種地点あたり10サンプル)の直径を計測した。各接種地点ごとに菌叢直径の平均値を算出し、各接種地点と、その深度に対応する無処理区の菌叢直径平均値との比較で防除価を求めた。   The bactericidal effect against Fusarium bacteria was measured by measuring the diameter of the Fusarium fungus flora (10 samples per inoculation point) on the medium surrounding the carrot pieces placed on the selective medium (see below). The average value of the flora diameter was calculated for each inoculation point, and the control value was determined by comparing each inoculation point with the average value of the flora diameter in the untreated area corresponding to the depth.
