芦笋茎枯病是山东省芦笋产区发生普遍,危害最重的一种病害。生产实践表明,常规杀菌剂对该病防效不甚理想。2%农抗120水剂是一种对多种土传病害兼具治疗和保护作用的抗生素类杀菌剂。试验表明,该药剂对芦笋茎枯病具有良好的防治效果。一、材料和方法 (一)供试药剂 2%农抗120水剂(武汉科诺生物农药有限公司);25%多菌灵可湿性粉剂 (二)试验处理试验共设五个处理:2%农抗120水剂稀释100倍、150倍、200倍;25%多菌灵可湿性粉剂稀释500倍;清水对照。 (三)试验方法每个处理重复4次,小区面积20m~2,随机区组排列。于发病初期,用上述稀释后药液进行灌根处理,每株(墩)灌
Asparagus stem blight is common in Shandong Province asparagus producing area, the most damaging a disease. Production practice shows that conventional fungicides on the prevention and treatment of the disease is not ideal. 2% of agricultural anti-120 agent is a kind of antibiotic fungicide that treats and protects many soil-borne diseases. Experiments show that the agent has good control effect on asparagus stem blight. Materials and methods (a) Test agent 2% agar 120 (Wuhan Kono Bio-pesticide Co., Ltd.) 25% carbendazim wettable powder (b) Test treatment The test consists of 5 treatments: 2% Anti-120 agricultural agent diluted 100 times, 150 times, 200 times; 25% carbendazim WP diluted 500 times; water control. (C) Test Method Each treatment repeated 4 times, the plot area of 20m ~ 2, random block arrangement. In the early stages of disease, with the above diluted solution for irrigation, each plant (piers) irrigation
