以竹炭生产副产物竹焦油为活性成分,采用菌落生长速率法测定了竹焦油对12种植物病原真菌的抑菌活性.室内盆栽药效试验表明,体积分数50%竹焦油乳油在质量浓度为2 000 mg·L~(-1)对黄瓜白粉病sphaerotheca fuliginea的预防效果达到79.13%.治疗效果达到78.36%;对黄瓜灰霉病Botrytis cinema的预防效果和治疗效果分别为42.38%和46.98%.其防效与对照药剂200mg·L~(-1)三唑酮没有显著差异.竹焦油具有较好的抑菌活性.表5参15

Fungicidal activity of bamboo tar against the phytopathogenic fungi Sphaerotheca fuliginea, Botrytis cinerea, and A hernaria solani, Fusarium graminearum, Rhizoctonia solani, Valsa mall, Sclerotinia sclerotiorum, Pyricularia oryzae, Bipolaris maydis, Fusarium oxysporum f. vasinfectum, Fusarium oxysporum f. cucumerinum, Venturia nashicola, Glomerella cingulata was tested using the colony growth diameter test method and using potted plants in a greenhouse. A comparison of bamboo tar at 2 000 mg·L~(-1) and methyl 2-[(4, 5-dihydro-4-methyl-5-oxo-3-propoxy-1H-1, 2, 4-triazole-1-carboxamido)sulfonyl]benzoate at 200 mg·L~(-1) using the control was made. Results for bamboo tar showed that against Sphaerotheca fuliginea the preventive effect was 79. 1%and the curative effect was 78. 4%;whereas for Botrytis cinerea the defensive effect was 42. 4%and the curative effect was 46. 9%. However, no significant differences were observed between bamboo tar and triadimefon(P<0. 05). These results demonstrated that bamboo tar had anti-fungal actions and may be a new potential agricultural fungicide in future. [Ch, 5 tab. 15 ref. ]
