摘要: 选用新型农药纳米级铜80%波尔多液可湿性粉剂为试验药剂,常规80%波尔多液可湿性粉剂为对照药剂,以4种主要烟草叶斑类病害角斑病、野火病、靶斑病、赤星病作为防控对象,分别在辽宁省开原市和凤城市试验地连续2年开展了田间防治试验。结果表明,与常规80%波尔多液可湿性粉剂相比,纳米级铜80%波尔多液可湿性粉剂对烟草角斑病、野火病、靶斑病和赤星病具有更好的防治效果,用量1 050 g/hm2连续施药2次,最好防治效果分别可达75.61%、76.90%、81.35%和60.71%。为了验证纳米级铜80%波尔多液可湿性粉剂的安全性,在开原市试验地进行烟株农艺性状调查。结果表明,纳米级铜80%波尔多液可湿性粉剂处理后的烟株,株高为118.12 cm,茎围为9.11 cm,有效叶片数为21.51片,最大叶面积为2 487.18 cm2,均略高于对照药剂,且对烟株生长发育无不良影响。

Abstract: A new pesticide, nano-grade copper 80% Bordeaux mixture wettable powder, was used as the test agent and conventional 80% Bordeaux mixture wettable powder was used as the control agent. Field control experiments were carried out in Kaiyuan City and Fengcheng City of Liaoning Province for two years for 4 major leaf spot diseases of tobacco, including angular spot, wild fire, target spot and brown spot diseases. The results showed that compared with the conventional 80% Bordeaux mixture wettable powder, the nano-grade copper 80% Bordeaux mixture wettable powder had a better control effect on tobacco angular spot, wild fire, target spot and brown spot diseases. The dosage of 1 050 g/hm2 was applied twice continuously, and the best control effects were 75.61%, 76.90%, 81.35% and 60.71%, respectively. In order to verify the safety of nano-grade copper 80% Bordeaux mixture wettable powder, the agronomic characteristics of tobacco plants were investigated in Kaiyuan City experimental field. The results showed that the plant height was 118.12 cm, the stem circumference was 9.11 cm, the effective leaf number was 21.51, and the max leaf area was 2 487.18 cm2, which were all slightly higher than those of the control agent, and this new pesticide had no adverse effect on the growth and development of tobacco plants.
