通过室内测定和盆栽防治试验,研究了黄皮酰胺纳米微乳剂(NMEC)对香蕉穿孔线虫的杀线活性和对红掌香蕉穿孔线虫病的防治效果.杀线活性测定结果表明,随着药剂处理时间延长,NMEC的杀线活性增强,在处理12h时,NMEC的杀线活性并不高于其他药剂;而在处理24h后,NMEC的杀线活性开始高于或显著高于常规黄皮酰胺,并与其他化学杀线剂差异不具有统计学意义;处理48h后,NMEC的杀线活性高于或显著高于其他供试药剂,并且较低用药量的NMEC杀线活性可以达到或接近较高用药量的其他药剂的杀线活性,1 mL的NMEC(400mg/L)处理48h的线虫校正死亡率高达99.33%±0.67%.在盆栽试验中,NMEC对红掌香蕉穿孔线虫病的防治效果显著好于常规黄皮酰胺,而且在用药量达到1 mg/盆及以上的施药量时,NMEC与灭线磷和克线磷的防治效果无明显差异;用4mg/盆NMEC处理的红掌病级数为1±0.32,显著低于1mg/盆和2mg/盆NMEC处理.
The inhibitory effect of humaramide nano-microemulsion (NMEC) on banana perforator nematode and the prevention and cure of banana perfumed nematode were studied by laboratory test and pot experiment.The results of kill activity showed that with the treatment of pesticide With prolonged treatment, the cytotoxicity of NMEC was enhanced. After 12 h of treatment, the cytotoxicity of NMEC was not higher than that of other drugs. However, the cytotoxicity of NMEC began to be higher or significantly higher than that of conventional clavulanic acid after 24 h treatment, And had no significant difference with other chemical nematicide agents. After 48 h of treatment, the cytotoxicity of NMEC was higher or significantly higher than that of other tested agents, and the cytotoxicity of NMEC at lower doses could reach or approach to higher The nematicide-corrected mortality of 99%, 0.67% of the nematodes treated with 1 mL of NMEC (400 mg / L) for 48 h was 99.33% ± 0.67% Was better than conventional clausenamide, and there was no significant difference in the control effect between NMEC and exophthalocyanine and cetyl-Phosphate when the dosage reached 1 mg / pot and above; the treatment of 4 mg / pot NMEC The series was 1 ± 0.32, significantly lower than 1 mg / pot and 2 mg / NMEC process.
