2001～2005年，对广西西贡蕉分布区的21个县市57个点进行了镰刀菌枯萎病的调查，调查的西贡蕉（ Musa paradisiaca L. ABB）品种有，黄心西贡蕉、白心西贡蕉和鸡蕉，发现镰刀菌枯萎病为害西贡蕉较为严重，经病区调查和原菌致病性接种测定结果，初步推断广西西贡蕉发生的枯娄病病原是香蕉枯萎病1号生理小种。应加强检疫工作，防止病原菌随种苗传入，发现病株要立即清除，经消毒处理后集中深埋，选用高效低毒农药加以控制。
A coordination polymer of [Zn(BBP)(p-CPOA)]n (where BBP is 2,6-bis(benzimidazolyl)pyridine and p-CPOA is p-carboxylato-phenoxyacetate dianion) has been synthesized and characterized by elemental analysis,IR,TG,and the single crystal structure was determined by X-ray diffraction. The crystal crystallizes in the monoclinic system,space group of P21/n with a=1.397 3(4) nm,b=1.138 4(3) nm,c=1.575 9(5) nm,β=91.805(1)°,V=2.505 4(13) nm3,Z=4,Dc=1.513 g·cm-3,μ=1.030 mm-1 and F(000)=1 168. Zn(Ⅱ) ion is penta-coordinated and surrounded by two carboxylate O atoms from two different p-CPOA groups in a bis-monodentate mode,three N atoms from the 2,6-bis(benzimidazolyl)pyridine ligand,completing a distorted trigonal bipyramidal coordination configuration. The structure is a helix with a long pitch of 1.138 4 nm. Under direction of supramolecular recognition and attraction,the adjacent chains are formed the double-stranded chain through π-π stacking between the 2,6-bis(benzimidazolyl)pyridine ligands and hydrogen-bonding interactions. A three-dimensional supramolecular network is further constructed through these interactions between the helices. The TG shows that its chain skeleton is thermally stable up to 382 ℃.
