- 摘要:
- 以甜瓜和籽用西瓜为试材，设2种自主研发配制的新型杀菌剂BX6、九醋酮和3种有抑菌作用的药剂苏纳米（Tsunami）、过氧乙酸、双氧水为处理,采用人工接种细菌性果斑病菌后喷施药剂和喷施药剂后再人工接菌2种处理方式，调查研究供试药剂防治后瓜类幼苗的发病情况及防治效果,为农业生产中预防和防治瓜类细菌性果斑病提供参考依据。结果表明：双氧水（1∶25）对甜瓜和籽用西瓜幼苗细菌性果斑病均具有较好的抑菌效果，保护和治疗作用较好，2种处理方式的防治效果分别为87.4%、84.5% 和60.5%、74.5%；苏纳米（1∶25~1∶75）、过氧乙酸（1∶25~1∶50）对甜瓜和籽用西瓜幼苗期均具有较好的预防保护效果；2种处理防治效果最高分别为78.3%、80.4% 和63.5%、81.6%；BX6（1∶8）对甜瓜和籽用西瓜幼苗具有较好的治疗效果，防治效果分别为61.3%和66.9%。
- Abstract:
- Muskmelon and edible seed watermelon were used as the test materials，and 2 kinds of new fungicides(BX6，Jiucutong) and 3 kinds of antibacterial agents(Tsunami，peracetic acid and hydrogen peroxide) were prepared.Two treatment methods were adopted with bactericide spraying firstly on the seedlings then inoculation of bacterial fruit blotch(BFB)，and after inoculating bacteria on the seedlings then bactericide spraying，the incidence rate and control efficacy of the seedlings after chemical treatment were investigated in order to supply reference for prevention of bacterial fruit blotch.The results showed that hydrogen peroxide (1∶25)，had a good antibacterial effects on muskmelon and edible seed watermelon seedling，and showed both protective and curative effects;the control efficacy was up to 87.4%，84.5% and 60.5%,74.5%,respectively;Tsunami(1∶25-1∶75)，peracetic acid (1∶25-1∶50)，had better protective effect both on muskmelon and edible seed watermelon seedling;the maximum of control efficacy was up to 78.3%，80.4% and 63.5%，81.6%,respectively；BX6 (1∶8) had better curative effect on muskmelon and edible seed watermelon seedling.And they were 61.3% and 66.9%。
