The results indicated as below: 1.The total latent infection rate and infection rate of two major fungi(Alternaria alternata and Fusarium sp)was reduced effectively with preharvest BTH treatment . The latent infection rate decreased with increasing of spraying times.Results showed that the four times of treatment by BTH is the best.

结果表明： 1。采前BTH处理有效地降低了果实生长发育期间的总潜伏侵染率及两种优势病原菌(Alternaria alternata和Fusarium sp)的潜伏侵染率，控制效果随处理次数的增加而提高，以100mg/L BTH处理4次效果最好。

Objective To research the change of multiplication, phagocytosis of THP-1 cells by Propionibacterium acnes,which is the pathogen of Fatal Bacterial Granuloma after Trauma.

All of these had shown that the induced resistance could be transmitted.Oligosaccharides had not shown any direct activity against Puccinia striifomis in vitro. This suggests that Oligosaccharides can elicit resistance to diseases of wheat, and are different from common pesticides.

不同浓度(25ppm、50ppm、100ppm)的5号提取物的体外抑菌试验表明，低聚糖对条锈菌没有明显的抑制作用，说明低聚糖不具有直接杀菌或抑菌作用，使小麦产生抗锈性的原因在于诱发寄主植物的抗病潜能，使植物本身产生对病原菌的抗性，这与普通杀菌剂显然不同。

Among them,29 stocks were highly resistant or resistant to all the three chief pathogens( Fusarirum moniliforme,Fusarium graminearum and Pythium sp .).

参加2～5年试验的玉米材料有38份，其中对三种主要病原菌(串珠镰刀菌，禾谷镰刀菌和腐霉菌)抗或高抗的有29份。

objective to investigate the infection of mycoplasma pneumoniae in children.methods the glutin agglutination rection was used, the diluting power of antibody of mycoplasma pneumoniae was more then 1:80, it was a positive sample.results 1 817 patients were detected, the positive rate was 30.7%,the female rate was higher than male rate, the highest rate were between three to six years old.conclusion mycoplasma pneumoniae is the main pathogen in children with respiratory tract infection, the positive rate was connected with age and nearly contact each other.

目的 了解肺炎支原体在青少年中的感染情况。方法采用明胶凝集的方法，若抗mp-igm滴度≥1：80，为阳性。结果共检测1817例，阳性率为30.7%，女性阳性高于男性，3～6岁的儿童阳性率最高。结论肺炎支原体的感染是青少年呼吸道感染的重要病原菌，阳性率与年龄有关，密切接触可引起局部流行。
