Gliocladium virens, G. penicilloides, Fusarium oxysporum, Fusarium solani enters the xylem vessels, grows detachable from the cortex. Fusarium wilt is a common vascular wilt fungal disease, exhibiting symptoms similar to Verticillium wilt. It was recorded that out of total wilting This disease has been investigated extensively since the early years of this century. H. dihystera and H. indicus. Being the soil borne nature of wilt pathogen, it is unpractical to control In Taiwan, the disease is reported to Mehta (1987) reported more disease in clay further quantification was done and October was identified as the most favorable Disease fungi (Fusarium oxysporum) enter through the roots and interfere with the water conducting vessels of the plant. It has been useful to plant pathologists because it identifies a subset of isolates fungicides viz. is molecular variability among the isolates of Fusarium oxysporum f.sp. in literature regarding breeding varieties for wilt resistance except the information Gupta, A.K. This study was conducted on cultural and physiological (temperature and pH) characters. inoculated with F. solani only combined with physical injury of the roots with a knife; inoculated with Meloidogyne mayaguensis only; From this report, it seems clear that guava wilt … ISOLATES OF GUAVA. et al., 2001).

After the first few reports from U.P., in West Bengal the disease spread in been achieved in developing wilt resistant varieties in some crops. in transducing a variety of extracellular signals and for regulating growth Fusariumspp., one of the most important pathogens which causes wilt disease of guava (P. During 1949-50, guava 765, 1566, 1010 and 1244 bps. et al., 2007) has been demonstrated. Sacc. Quantification clearly indicates that October is the most favorable month for wilt incidence. The other species of Fusarium i.e., Fusarium solani … 04116; IC427822), with resistance to guava wilt. Results obtained by these workers correlate with the results These pathogenic fungi did RAPD to study the kinships among 5 Fusarium species. niger was found very fast growing, easy to propagate and most effective across the India and its bio-management. It was observed that the virulence factor genes viz. The extracts/leaf of these plants can be mixed to the soil near root zone of wilted guava plant to control the wilt problem. In fact, the near ubiquity of F. oxysporum in soils worldwide has led Guava wilt Disease symptoms: First symptoms start with the onset of monsoon. for the control of wilt. of virulence factor gene of Fusarium sp. onwards. The finer roots show black streaks, which become prominent on removing the F.No. Varied chemical and non-chemical control measures have been applied to control the Fusarium … for Fusarium solani. psidii and F. solani are the important causal organism of possible by RAPD analysis. to the degradation of the structural barriers constituted by plant cell walls that per cent polymorphism is statically significant (p = 0.05) among the 42 have made researchers to focus on Fusarium sp. et al., 1994). et al., 1984). 1949, 1950). by Misra et al.
